ADC autorange
Dear friends, I am on a project, that uses an atmega16 @ 16MHz and a 16-bit bipolar ADC. Communication is made with SPI @ 4 MHz. The ADC is sampling a signal from an amplifier and...

using two timers for time control
Hello. I use an atmega16 at 16 MHz. The microcontroller "talks" with spi to a DAC in order to produce a specific waveform of potentials. For the timing I use timer2 in CTC mode...
