433MHz wireless module configuration
https://www.electronics-lab.com/433mhz-wireless-module-configuration/
Dziku discuss how to configure a cheap 433MHz wireless module for serial communication: HC-12 are cheap 433MHz wireless serial port communication modules with a range up to 1800m in open space. Each costs about $5 when bought from China, and 2 of them can create wireless UART link that can be used, for example, to […]
samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
https://www.electronics-lab.com/samdev_09-mini-devboard-atmels-samd09-arm-cortex-m0-microcontroller/
A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and therefore has […]
USB to UART Converter with GPIO – MCP220
https://www.electronics-lab.com/usb-uart-converter-gpio-mcp220/
The Module is based on The MCP2200, which is a USB-to-UART serial converter which enables USB connectivity in application that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256-bytes of integrated user EEPROM. The MCP2200 has eight general purpose input / output pins. Four […]
Hacking a UART on a blood pressure cuff
https://www.electronics-lab.com/hacking-uart-blood-pressure-cuff/
moamindustries.com hacked an Omron RS8 blood pressure cuff by adding a UART interface to it. As part of a prototype developed 12 months ago I was tasked with reading measurements from a blood pressure cuff [sphygmomanometer] in real time. Not surprisingly there are no consumer level devices that have a serial interface because what ‘normal’ […]
Serial Port Communication in C#
https://www.electronics-lab.com/serial-port-communication-in-c/
Maurizio tipped us with his latest article on how to use Serial Port in C#. The article does cover the basic code needed to achieve serial communication. The serial port of the PC is a very important resource both in industrial environment and in home-made electronics, due to the wide popularity of the UART interface […]
