Sync two TC0 timers to control full-bridges I built a board that has to control 3 different full-bridges for DC motors. Think as 3 different axis. The MCU is an `xmega128A1u`. Due to the other peripheral constraints I... |

Definitive way to acquire 8 ADC input with DMA I read this very old thread, and I'm reading the A4U datasheet, the AVR1300 and AVR1304 app notes. Still I'm not sure how to do a very simple thing: reading all PORTA 8 ADC inputs... |

Improve SPI speed I'm using an xmega32A4U to control an AD5592 DAC. My goal is to write all 8 outputs with a frequency of 20 kHz. To update a single output I need two bytes. The MCU is running at... |
