This project aims at providing a UART interface to a A7105 2.4 GHz wireless tranceiver. An Atmel Attiny85 with a soft UART and soft SPI is used for low level communication and some basic abstraction. The current use case is programming another chip over the air, so error-free bulk transfers are the top priority.
The soft UART and SPI work.
For the soft UART, avr-softuart by Brian Lalor is used. It is based on the Timer-based AVR Software-UART by Martin Thomas, which in turn is based on the generic software uart by Colin Gittins.
