MCUprog UPDI is a windows program with CLI and GUI for programming various Microchip MCU devices using Microchip CMSIS-DAP based debuggers and standard TTL serial port.

HV UPDI / UPDI programmer software for Arduino (targets Tiny AVR-0/1/2, Mega AVR-0 and AVR-DA/DB MCUs)

This library enables you to use Interrupt from Hardware Timers on Arduino AVRDx-based boards (AVR128Dx, AVR64Dx, AVR32Dx, etc.) using DxCore. These AVRDx Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software tim…
