Today, I have flashed my first ATtiny85V with the elnec beeprog programmer. It was really easier as I expected. Now, I would like to flash my application to use it as an extern module. With the bootloader, you have a tool doing this but it is only on widows. I would like to use the uart7 to speak with the ATtiny. However, I see in ChibiOS that neither the Serial Driver neither the UART driver for the UART7 are implemented. I will see tomorrow, what is the best solution with one day left.
