Using the UART interface
5 June 2018
UART (universal asynchronous receiver/transmitter) is a communication interface used between two microcontrollers. Data signals are transferred using two lines, one for transmitting signals (Tx) and one for receiving signals (Rx).
The FTDI USB to TTL serial converter module
5 June 2018
The FTDI USB to TTL serial converter module is an UART (universal asynchronous receiver-transmitter) board used for TTL serial communication. It is a breakout board for the FTDI FT232R chip with an USB interface, can use 3.3 or 5 V DC and has Tx/Rx and other breakout points.
Connecting the ESP-01 module to a breadboard and FTDI programmer
12 September 2017 | Updated 4 June 2018
When compared with some other microcontroller boards (e.g. the Arduinos), the ESP8266 is slightly more complex to hook up to a serial port for programming. This post will show how to connect the ESP-01 module to a breadboard and FTDI programmer for ‘flashing’ purposes.
Understanding the digital read pin on a microcontroller
6 July 2017 | Updated 10 June 2018
When working with electronics, one will very often come across working with digital readings. Digital read (and write) pins are available on many microcontrollers and is one of the simpler pins to work with.
