Fast graphics with ready-to-use modules based on FT81x

Posted on 16 December, 202016 December, 2020 by mixos

The new gen4-FT81x display modules from 4D Systems represent a ready-made solution based on graphics chips from Bridgetek. The main advantages include easy and intuitive programming, powerful SW IDE, many useful functions and three display sizes. (SOS electronic)

FT81x graphics processors were introduced in our recent article.

For many years, we have been associating 4D Systems with their own graphics processors – especially Picaso and Diablo 16, which are still prospective and active.

However, for those who, for whatever reason, prefer Bridgetek’s FT81x graphics processors, they bring an elegant solution with seven new 4.3″, 5″ and 7″ gen4-FT81x modules.

Here you can find types with a resistive and capacitive touch panel, as well as with the demanded glass black frame (CLB – cover lens bezel), which also greatly simplifies assembly on the front panel simply by glueing into the hole.

The FT812 and FT813 chip-based modules allow you to create a powerful graphics application with minimal effort, which, in addition, has very low demands on the performance of the host processor. Bridgetek offers freely available development environment EVE Screen Designer (ESD).

Nowadays more than ever it is often more advantageous to use a ready-to-use module than to develop your own solution, especially for small and medium production series.

Please, find the new gen4-FT81x modules e.g. gen4-FT812-50T directly in our warehouse.

Main Features:

LCD TFT Screen with Resistive or Capacitive Touch.
Mono PWM audio output with separate amplifier enable
Onboard FTDI FT812 or FT843 Video Engine
64 voice polyphonic sound synthesizer
PWM dimming control for LCD backlight
JPEG and Motion JPEG decode
Single 5.0V supply

Modules with Wirepas Mesh protocol for Massive IoT

Posted on 16 December, 2020 by mixos

Würth Elektronik has entered into a partnership with the Finnish software developer Wirepas. The aim of the agreement is to offer a portfolio of radio modules that use the IoT network protocol Wirepas Mesh from 2021. This innovative technology can be used to create large IoT networks, for example of battery-powered sensors, in which each participant also functions as a router. The mesh is self-healing and scalable as required. As part of an “early bird offer”, Würth Elektronik customers can receive from today the proven Proteus III / Thyone I hardware with firmware from Wirepas.

The design principles of the software stack from Wirepas were geared from the beginning to the requirements of the industry with regards to reliability, scalability and longevity of devices in battery operation. As a provider of compact and energy-saving radio modules in the 2.4 GHz band, Würth Elektronik is the ideal partner for manufacturing, selling and supporting ready-to-use radio modules for Wirepas mesh networks.

“This will make us a one-stop shop for companies willing to develop IoT solutions for remote monitoring and remote control of devices based on the extremely flexible and scalable Wirepas technology,” explains Luca Settembre, product manager for GNSS and Wirepas in the Wireless Connectivity & Sensors Division at Würth Elektronik eiSos. “There are a lot of interested parties and developers who are urgently waiting for Wirepas radio modules available in smaller numbers. We have decided to be very flexible and offer a solution before the official start. “

Wirepas modules

With immediate effect, Würth Elektronik customers can receive their first radio module with Wirepas basic firmware. In cooperation with Wirepas, Würth Elektronik offers standard hardware in which the Wirepas firmware can be customized according to customer requirements. This means that an intelligent mesh network can be implemented for the customer within a very short time. The hardware is based on the Nordic chipset nRF52840, which has already proven itself very well at Würth Elektronik as the Bluetooth LE 5.1 module Proteus-III or as the 2.4GHz proprietary radio module Thyone-I. From the end of Q1 2021, a standard radio module, like all products at Würth Elektronik eiSos, will be available from stock without a minimum order quantity.

ATmega3208 Powered Development Board for Embedded Applications

Posted on 15 December, 2020 by Abhishek Jadhav

Microchip has recently launched a simple yet powerful development board aimed at embedded and IoT applications. As the name suggests, the development board is powered by the ATemga3208 from Microchip. The microcontroller features an 8-bit AVR processor clocked at up to 20MHz and comes with up to 32 KB Flash, 4 KB SRAM and 256 bytes of EEPROM. The AVR family of processors is famous for their performance, power efficiency, and design flexibility and are widely used in embedded systems applications.

The development board has an onboard decoupling capacitor, which suppresses high-frequency noise in the power supply signals, and Unified Program and Debug Interface, which is an interface for external programming and on-chip debugging of a device. This programming header includes the USART.0 TX and RX signals in “UPDI+” that is in a 2×3 o.1″ layout matrix at the lower end of the board.

The LED is attached to the PF5 pin that can be seen from the figure and is connected through a 2k2 current-limiting resistor to ensure that the amount of current does not exceed the limit that the circuit can handle. Similarly, the onboard button is connected to the PF6 RESET pin via a resistor, while the PF6 pin is the default pin for the GPIO mode.

Additionally, you can see an extra 2-pin header that has a VCC and GND pin for additional connections that are placed above the onboard LED. Coming back to the heart of this development board that is ATmega3208 chip has a CPU Speed of 20 MIPS/DMIPS. The chips also have digital communication peripherals, including 3x-UART, 1x-SPI, and 1x-I2C, along with a 10-bit 12 channel analog to digital converter input.

The popular solution for low-power design is to put it into an appropriate sleep mode. For this, the chips have three sleep modes, including idle, standby, and power down. It also has an event system, which is popular among the AVR microcontrollers as it lets you connect the on-chip peripherals without writing any code.

The advised operating temperature is -40 to 125 degrees Celsius and an operating voltage of 1.8 to 5.5 volts. I wouldn’t be surprised to see this ATmega3208 powered development board aiding in several embedded and IoT applications, as mentioned before.

You can buy this board on Tindie for $18.
