Why to use ATMEGA16U with ATMEGA2560
puneet1984 wrote: Thanks a lot for the reply.   So, we can use a CH340 instead of the ATMEGA16U. Will save two steps of programming ATMEGA16U - burning bootloader and burning...

[SOLVED] Question: AVR, interrupts and ISR
Kartman wrote: 100 loops at 24MHz is how long? This will vary depending of the interrupt rate of your other code. Use another timer and test the interrupt flag to get a consistent...
