MIPI CSI-2 v4.0 to Augment Always-On, Low Power Computer Vision Applications

Posted on by Saumitra Jagdale

MIPI example

MIPI Alliance has just announced the launch of the latest MIPI CSI-2 v4.0 interface. It adds features for environmental monitoring, multi-pixel compression and RAW28 color depth for safety-critical applications. Before understanding v4.0, let’s take a look at what MIPI CSI-2 is and its existing versions.

MIPI CSI-2 is a camera interface that connects an image sensor with an embedded board to control and process the image data. This helps the sensor and embedded board to act together like a camera system to capture images.

How does CSI-2 Protocol Work?

MIPI CSI-2 architecture and functioning

In a computer vision application, the image sensor captures and transmits an image to the CSI-2 host processor/SoC. The image is placed in the memory as individual frames. Each image frame is broken down into packets that include data format and error correction code (ECC) functionality. A single packet travels through the D-PHY layer and is split further according to the number of virtual channels. On the receiver end, the receiver is provided with a D-PHY physical layer for image extraction and error correction.

CSI-2 Protocol Timeline and Features

CSI-2 offers a maximum bandwidth of 6 Gbps, with an attainable bandwidth of 5 Gbps. MIPI CSI-2 supports high-resolution imaging. It can easily transmit images and videos in 1080p, 4K, and 8K formats. It is suited for both single and multi-camera implementations.

The MIPI CSI-2 v1.0 specification was released in 2005. MIPI CSI-2 is divided into the following layers: Physical Layer (C-PHY/D-PHY), Lane Merger Layer, Low-Level Protocol Layer, Pixel to Byte Conversion Layer and Application Layer

In April 2017, the CSI-2 v2.0 specification was released. It brought support for RAW-16 and RAW-20 color depth, increased virtual channels from 4 to 32, Latency Reduction and Transport Efficiency (LRTE), Differential Pulse-Code Modulation (DPCM) compression and scrambling to reduce Power Spectral Density.

RAW is the format of the image captured by the sensor without any processing. 16 or 20 is basically the number of bits per channel. Ex – An 8-bit camera can capture 2^8=256 different tonal values, by permutation and combination in each of the Red, Green and Blue channels. That makes a total of 256 X 256 X 256 = 16.7 million colors. Hence, in simple terms, MIPI CSI-2 v2.0 has the ability to transmit RAW-16 or 20 images to the CSI-2 host as per industry requirements.

Also, increasing the number of virtual channels from 4 to 32 augments the image transmission capabilities as a higher number of packets can be transmitted at the same time. This and Latency Reduction and Transport Efficiency (LRTE), Differential Pulse-Code Modulation (DPCM) compression makes CSI-2 v2.0 especially useful for use cases like Advanced Driver Assistance Systems (ADAS). CSI-2 v2.0 features are literally suited to transmit different inputs from multiple sensors with varying ranges and intensity.

Different image inputs with varying ranges

MIPI CSI-2 v3.0 was released in 2019 and came with support for RAW-24 color depth.

CSI-2 v4.0 – More with less

Building on the machine awareness capabilities introduced in MIPI CSI-2 v3.0, v4.0 adds features to reduce lower power consumption, bandwidth demand and hence improving the ability to process better quality image input.

MIPI CSI-2 v4.0 is the first to support transmission of CSI-2 image frames over the low-cost, low-pin-count MIPI I3C/I3C basic two-wire interface. Some of the new features introduced by MIPI CSI-2 v4.0 are AOSC, Multiple-Pixel compression(MPC) and RAW-28 pixel encoding. Just like RAW 16 or 24, RAW 28 is the new pixel encoding supported by MIPI CSI-2 v4.0 for transmission of images of greater HDR to the processor for safety-critical operations like ADAS.

Another very important enhancement is the Always-On Sentinel Conduit or AOSC. This enables the image frame streaming from image sensor to VSP over a low-power MIPI I3C bus. This enables monitoring of the surrounding and triggers the host CPUs only when significant events happen, to save power.

Another important feature is the MPC or Multi-pixel compression. MPC reduces the bandwidth demand by compressing multi-pixel and standard Bayer CFA images with better efficiency. Hence, you can use the latest image sensors with high HDR image output without proportionally increasing the bandwidth.

To top it all off, CSI-2 v4.0 is backward-compatible with all previous versions of the MIPI specification.

Sensor data collection from STM32 and SHT85 using Bluetooth Low Energy

Posted on by mixos

A simple Bluetooth Low Energy project showing how to get sensor data from SHT85 which is connected to the STM32 Nucleo-144 using javascript.

Requirements :

When the BleuIO Dongle is connected to the Nucleo board’s USB port, the STM32 will recognize it and start advertising the sensor values that it reads from the SHT85 along with the sensor serial number. It will update these values every 10 seconds.

Setup the project

Part 1 : Download the project

Get project HERE

https://github.com/smart-sensor-devices-ab/stm32_bleuio_SHT85_example

Either clone the project or download it as a zip file and unzip it, into your STM32CubeIDE workspace.

Part 2 : Importing as an Existing Project

From STM32CubeIDE choose File>Import…

Then choose General>Existing Projects into Workspace then click ‘Next >’

Make sure you’ve chosen your workspace in ‘Select root directory:’

You should see the project “stm32_bleuio_SHT85_example”, check it, and click ‘Finish’.

If you download the project as a zip file you will need to rename the project folder from ‘stm32_bleuio_SHT85_example-master’ to ‘stm32_bleuio_SHT85_example’

Running the example

In STMCubeIDE click the hammer icon to build the project.

  • Open up the ‘STMicroelectronics STLink Virtual COM Port’ with a serial terminal emulation program like TeraTerm, Putty or CoolTerm.
Baudrate: 115200
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
  • In STMCubeIDE click the green play button to flash and run it on your board. The first time you click it the ‘Run Configuration’ window will appear. You can just leave it as is and click run.
  • Connect the BleuIO Dongle.

Access sensor data from a web browser

We wrote a simple script that connects to the BleuIO dongle and reads advertised data from STM32.

For this script to work, we need

Steps

Create a simple Html file called index.html which will serve as the frontend of the script. This Html file contains some buttons that help connect and read advertised data from the remote dongle, which is connected to stm32.

<!DOCTYPE html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

    <!-- Bootstrap CSS -->
    <link

      rel="stylesheet"
      integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3"
      crossorigin="anonymous"
    />

    <title>STM32 Read sensor value</title>
  </head>
  <body>
    <div class="container mt-5">
      <h1>Sensor data collection from stm32 using Bluetooth Low Energy</h1>
      <button id="connect" class="btn btn-primary">Connect</button>
      <button id="getdata" class="btn btn-success">Get device data</button>
      <div id="loader"></div>
      <br />
      <div id="response" class="fw-bold"></div>

      <script src="./index.js"></script>
    </div>
  </body>
</html>

Create a js file called script.js and include it at the bottom of the Html file. This js file uses the BleuIO js library to write AT commands and communicate with the other dongle.

import * as my_dongle from 'bleuio'

//connect to BleuIO
document.getElementById('connect').addEventListener('click', function(){
  my_dongle.at_connect()
})
//get sensor data
document.getElementById('getdata').addEventListener('click', function(){
  document.getElementById('loader').innerHTML = 'Loading'
  //set the BleuIO dongle into dual role
    my_dongle.at_dual().then(()=>{
      // sensor id of the device that we are trying to get data from
      let sensorID='05084FA3'

      //look for advertised data of with the sensor id
        my_dongle.at_findscandata(sensorID,4).then(x=>{        

          //split the advertised data from the respnse
          let advdata= x[x.length-1].split(" ").pop()

          //trim the advertised string to only get sensor response
          const result = advdata.split(sensorID).slice(1).join(sensorID) 

          //get temperature and humidity value
          let temp = result.substring(0, 4);
          let hum = result.substring(4, 8);

          //convert from hex to decimal and device by 100
          temp = parseInt(temp, 16)/100
          hum = (parseInt(hum, 16)/100).toFixed(1)  

          document.getElementById('loader').innerHTML = ''
          document.getElementById('response').innerHTML = `Sensor ID : 05084FA3 <br/>
          Temperature : ${temp} °C<br/>
          Humidity : ${hum} %rH<br/>`              
        })
    })
    
  })

The script js file has two button actions; connect and read advertised data.

We also need to update the Sensor ID on line 13 of script js. The Sensor ID of this example project is 05084FA3, which we got from SHT85.

Therefore this script looks for advertised data that contains sensor ID 05084FA3. After getting advertised data , we split the temperature and humidity information and show it on our index.html page.

Now we need a web bundler. We can use parcel.js

Once parcel js is installed, let’s go to the root directory and type “parcel index.html”. This will start our development environment.

Let’s open the script on a browser and select the right port where the dongle is connected.

The web script is available on the web script folder of the GitHub repository.

MAX16163/MAX16164 nanoPower On/Off Controller

Posted on by mixos

Maxim’s MAX16163 and MAX16164 nanoPower on/off controllers with programmable sleep time extend battery life up to 60%

Maxim’s MAX16163 and MAX16164 are nanoPower on/off controllers with programmable sleep time. The devices integrate a power switch to gate an output, which provides up to 200 mA load current.

The MAX16163 and MAX16164 use either an external resistor or an I2C bus to program the sleep time. When the device powers up, it checks the connection on the PB/SLP pin. If the resistance between the PB/SLP pin and ground is larger than 5.5 MΩ, the device is configured as I2C programmable. Otherwise, the device is configured as resistor programmable.

When the MAX16163 powers up, it measures the resistance on the PB/SLP pin to ground and sets the sleep time properly. It then asserts the OUT output. When the downstream device (e.g., a μC) finishes its task, it asserts a falling edge on the CLRB pin. The MAX16163 then deasserts OUT and the sleep timer starts. When the sleep timer expires, the MAX16163 asserts OUT again.

When the MAX16164 powers up, it measures the resistance on the PB/SLP pin to ground and sets the sleep time properly. It then keeps OUT deasserted and puts the device in shutdown state. The MAX16164 does not assert OUT until a pushbutton closure on the PB/SLP pin.

The MAX16163 and MAX16164 operate over the -40°C to +125°C temperature range and are available in a 1.54 mm x 1.11 mm, 6-bump thin wafer-level package (WLP) and a 6-pin μDFN package.

Block Diagram

Features

  • Ultra-low current saves power
    • 30nA IQ in sleep timer state
    • 10 nA IQ in shutdown state
    • VCC range: 1.7 V to 5.5 V
