    Problem flashing Atmega328P U-TH MCU

    Hi all, I've been having a very big problem since 2 days. I got a brand new Atmega328P U-TH IC and made a custom board around it. Due to covid lockdown I am not able to purchase any programmers like USBasp, so I decided to use my Arduino UNO as ISP programmer. However, When I tried to burn the...

    Microdevt - Interrupt-based Drivers

    Hi there! Does anybody known how to code an interrupt driven driver using Microdevt toolkit (www.kw-net.com) ? I am trying to develop a simple driver on my atmega328 that enqueues a bitstream from an other uC. The bitstream is read on an input pin and then processed if a certain amount of data...

    AVR Datasheet

    As I'm a new microcontrollers student, I read in a book that in ATmega168 the hardware register for Port B is at byte number five of the memory. And I downloaded the datasheet and kept searching for this in the "pin configuration" section, but I could not figure out where to find this specific...
