SOS electronic: 9″ intelligent embedded display uLCD-90

Posted on by mixos

Apart from the simple and fast development of graphics applications, a larger display has been added to the pool of benefits of working with 4D Systems displays. New 9” module with resistive or capacitive touch panel and with adapters for Raspberry Pi and Arduino.

Intelligent displays with powerful (free) software for the simplest possible development of applications may already be familiar to you from several of our articles.

Display modules from 4D Systems have attracted many fans especially for the ability to easily and quickly develop an application in 4DGL (C-like) graphics or even graphically, practically by “drag and drop” method using a wide range of ready-to-use widgets.

The proprietary graphics processor (Diablo 16) provides enough power and I/O functionality to control the surrounding electronics. Thus for not very complex applications, these modules can replace the Host processor and become the core of the application.

The 4D Workshop 4 IDE development environment provides a variety of ready-to-use buttons, sliders, switches, analogue gauges and other graphics that, thanks to a touch panel, can be used to replace classic electromechanical components to simplify wiring, reduce costs and increase device reliability.

Even 4.3 ”and 7” display can accommodate a fair number of different indicators and controls to create powerful graphical manipulation (HMI). This is even truer for the new 9-inch uLCD-90DT and uLCD-90DCT, which has a 1.7x larger area than the 7-inch module.

The gen4 uLCD family design is the same for all available modules and all have a plastic white frame as well as pins on the FPC connector. However, uLCD-90 does not have an additional white plastic frame with eyelets for side mounting for screws but these eyelets are metal and are directly part of the LCD module design.

Advantages / Features:

  • 9 ” intelligent RGB display module 800×480 px
  • fast application development in a powerful development environment (freeware)
  • easy to use graphics
  • slot for uSD card
  • capable of standalone operation
  • single power supply 4 to 5.5V

The easiest way to connect the module to a PC and start working in the 4D Workshop 4 IDE is to use the 4D-UPA programming module.

A big advantage of 4D Systems modules is the mutual compatibility of modules and applications. The application written for the 4.3″ module can also be used for the 9″ module, but of course, it is necessary to adjust the placing of graphic elements (or add more of them) to use the significantly larger display area.

The uLCD90 is available with a resistive (uLCD-90DT) or a capacitive (uLCD-90DCT) touch panel as well as with adapters for Raspberry Pi and Arduino. The nominal supply voltage is + 5V (4-5.5V, approx. 760 mA).

Thanks to many years of cooperation with the manufacturer, we can deliver any 4D Systems product in a short time and at competitive prices.

SoM provides ARM Cortex-A7 performance in QFN-style package

Posted on by mixos

Direct Insight has introduced a QSMP Solder-down module featuring the STMicro ST32M1 single/dual core ARM Cortex-A7 processor. The module has been manufactured by the Direct Insight’s partner, Aachen-based Ka-Ro Electronics. [via]

The SOM has been built around an ST32M1 family processor that is powered by a single or dual 650MHz ARM Cortex-A7 core, which is supported by a separate ARM Cortex-M4 operting at 200MHz with up to 512MB of DDR3L RAM and up to 4GB eMMC Flash. The ST chip also offers a wide range of interfaces. The chip has been developed to provide low power operation, combined with security features and high-performance. To boost performance, the ST32M157C can offer a powerful 3D GPU and the integrated security features include secure boot and an AES/TDES/SHA crypto-engine.

The QSMP SoM measures 27mm square and is only 2.3mm high. It has been manufactured in a solder-down package that features a QFN-type pin-out that is based on a 1mm pitch with 100 edge-located pads. The SoM has been built this way to assist inspection and simplify routing. It even permits a two-layer baseboard and a base plane. The ground plane design helps the modules ‘float’ into position during reflow, unlike a BGA which requires X-Ray inspection to ensure full connectivity. The QS solder-down modules are small enough to prevent warping. The package’s design also improves thermal efficiency and EMI performance with the base functioning as both a ground pad and a thermal conductor. The modules can operate across the industrial temperature range of -40 or -25 to +85degC.

David Pashley, Direct Insight’s MD says,

“Solder-down SoMs offer simplicity and reduced cost but can be tricky to handle during production. Ka-Ro’s QS modules address these challenges, simplifying inspection and PCB layout, while delivering huge processing power – all in a miniature package”.

The module has a broad range of connectivity options including CANbus (ST32M153A and ST32M157C), UART (x3), SPI (x2), I2C (x2), Audio, Gb Ethernet, SD, USB Host and Client and a parallel or MIPI-DSI (ST32M157C) display. It operates on a single 3.3V supply.

The ST32M1 ARM Cortex-A7-powered QSMP SoM also has a dedicated development system, equipped with Linux BSP.

Pandauino Narrow Boards Features ATmega644/1284-based boards

Posted on by Tope Oluyemi

 

644 Narrow and 1284 Narrow are small, simple, ATmega644/1824-based boards, which are designed to improve small footprint Arduino projects. The Narrow board enables two to eight times more flash and RAM resources and ten more digital I/O as compared to an Uno/Nano, plus total compatibility. The Catalonian maker Thierry Guennou claims:

“they are the smallest ever breadboard-compatible development boards to feature the Microchip ATmega644 or ATmega1284 microcontrollers.” He continues “Many microcontroller-based projects need to have the smallest possible footprint and a lot of resources. Up until now, the Arduino Nano has certainly been popular for its price/performance value and small footprint…”

The 644 and 1284 Narrow boards both feature a large amount of effective Flash and RAM. They are described as “Effective” because the code generated on 8-bit MCUs is much smaller than on 32-bit MCUs. Hence, you can load a bigger program on a 128k 8-bit MCU than on a 256k 32-bit MCU! ATmega644/1284 also has EEPROM that adds to their total storage capabilities. Cortex processors can emulate EEPROM, but this further consumes flash (in whole pages) and wears out the memory.

Narrow Narrow 1284 Board

The specifications varies by the model you are choosing. For the Pandauino 644 Narrow, it enables ATmega644 microcontroller and features 64kB of flash storage, 4kB of static RAM (SRAM), and 2kB of EEPROM storage on-board. However, the Pandauino 1284 features ATmega1284  microcontroller and enables flash storage of 128kB, SRAM to 16kB, and 4KB of EEPROM. Despite the differences in the microcontrollers they both feature, they share some similarities in features, like they enable the same amount of break out pins at 24 digital and eight analog I/O pins, however, the 1284 Narrow offers eight pulse-width-modulated outputs, while the 644 Narrow offers six. They both offer extra connectivity than the UNO and Nano boards. Both boards measure at 1,097mm² in footprint and weigh 8g.

For manufacturing plans, he says

“PCBs will be high quality and lead-free. Sourcing will be from specialized distributors I have used reliably in the past. Depending on the number of backers, I will either:

.Assemble, program, and inspect the boards myself.
.Assemble partly with an assembly company and complete the programming and inspection myself.”

As the campaign progresses, more information about schematics, programming examples and user manual will be provided with a GitHub repository. Funding ends on Jul 30, 2020 at 04:59 PM PDT (11:59 PM UTC), and Crowd Supply will handle all deliveries. Within USA, orders will be free of charge, while all international (non-US) will be charged a surcharge. More details about the Pandauino 644 and 1284 Narrow boards are can be found  on Crowd Supply, pricing at  $29 and $35 respectively.

SE-DPIN: 16 to 256 Channel I/O Card For PXIE and ATE Instruments

Posted on by mixos

Salland Engineering delivers over 28 years of services to develop and build custom ATE instruments for the semiconductor industry. CEO, Paul van Ulsen said;

“Building high density instruments is always about finding the right balance between performance, density/throughput within the right available power and cooling at the right cost per channel.“

To address these challenges, Salland decided to design the Instrument IP themselves. This enables customers to benefit from proven and available building blocks to achieve high performance and very high density at the right cost.
Salland’s ‘’off-the-shelf’’ custom OEM instrument solutions allow customers to build ATE instruments at a fraction of the cost and at minimal risk. In this respect Salland follows a similar approach as Elevate, building standard solutions for custom applications.

Salland’s latest proof of concept is a scalable 200MHz DPin IO technology based on ElevATE’s Mystery Octal SOC ASIC. This is a 64ch PXIe card with 8 Mystery ICs onboard featuring:

  • 64 (/32)-channel, 200MHz/up to 500Mbps Digital I/O card in PXIe format
  • Based on ElevATE Mystery ASIC and a FPGA based timing generator
  • Scalable architecture in blocks of 16 channels up to 256+
  • Technology can be used in all kind of form-factors; modules, ATE, PXIe, etc.

With the Mt. Mystery ASIC, Salland was able to dramatically increase channel count and speed in an air-cooled solution designed to fit into the strict power/space requirements for a PXIe card.

“We are very excited by what our engineering partner, Salland, has been able to do with our class-leading Mt. Mystery ASIC. We know our customers will appreciate the density of their solution and the flexibility of the PXIe architecture.” – said David Kenyon, Elevate CEO.

Founded in 2012, Elevate Semiconductor is the worldwide leader in the design and manufacturing of Automated Test Equipment (ATE) semiconductors for the automotive, Memory, LCD, Industry and IOT markets.

Building a Chaotic Oscillator from Common Components

Posted on by mixos

Tim’s Blog writes:

A chaotic oscillator is an electronic circuit that can exhibit “chaotic“, nonperiodic behavior. A commonly cited example is Chua’s circuit, but there are many others. I always regarded these as carefully designed, rather academic, examples. So I was a bit surprised to observe apparently chaotic behavior in a completely unrelated experiment.

A while ago a took an interest in recreating an ancient logic style based on discrete transistors, resistor-transistor-logic (RTL), with todays components. I discussed some of my findings earlier and continued to work on transistor selection and circuit optimization afterwards in collaboration with Yann from Hackaday TTLers. The tool of choice to evaluate the switching speed of different logic gate designs is to build ring-oscillators from chains of inverters.
