c++ - How to manage the lines com port/uart for the firmware microcontroller (atmel), which is manual?

问题描述:

I want to write a new program to flash Atmega avr microcontrollers. Start planning for the possibility of firmware only atmega8/16/32. The project will be open source. On the internet i only found the source avrdude. I read the datasheet atmega 8/16/32.

But this is not enough for me, not all clear. What books, source codes, articles you advise me. I have experience firmware atmega8/16.I worked with uart/usart, pwm, interrupts.Thank you.

网友答案:

Maybe Atmel's Application Note AVR910: In-System Programming will get you closer to what you want to do.

It also has a section about 'A Simple Low-cost In-System Programmer'.

Note that you will probably not be able to have a PC's UART output SPI. Using the parallel port (LPT) is the common solution.
