USI Serial UART Send on ATtiny
In my previous post, USI Serial UART Receive on ATtiny, we discussed how to implement a Serial UART receiver on an Atmel ATtiny using the USI module. This post describes how to implement a simple…
USI Serial UART Receive on ATtiny
Many ATtiny microprocessors don't include a hardware UART, but do include a Universal Serial Interface, USI. The USI module can be used to implement SPI, TWI (also known as I2C) and UART serial…
Tuning ATtiny internal oscillator
The internal oscillator of an ATtiny can be inaccurate and might require tuning. This post discusses how to do that if you have access to an oscilloscope or a frequency counter. An accurate clock…
Borrowing an Arduino Timer
If you want to use a microcontroller timer for your own purposes and you are using Arduino you might find that you need to borrow a timer from the Arduino core and then give it back. The ATtiny85…
