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... |

Are the xmega still supported from Microchip? Even I'm aware they released some "new" xmega, they don't appear in the 8-bit family as new neither popular: https://www.microchip.com/paramC... You have to... |

Removing 0x04 Extended Linear Address records When I import a project from AtmelStudio to MPLAB IDE X I notice the same project leads to different HEX output files. In particular MPLAB IDE X uses the Record Type 0x04:... |

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... |

Debug reset cause... without a debugger I'm working on a project with an xmega64A3U that runs in an inaccessible place. I have a serial line and I can program the MCU with the bootloader. The board ran fine for months.... |

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... |

Prepend some bytes to an array (i2c) Hi guys, I need to improve a bit some functions I'm using to reduce the amount of RAM. I'm working on xmega (yes, I know I can switch to a bigger one, but I want to learn how to... |
