Questions tagged [atmega32]

ATMega32 is an 8-bit AVR microcontroller with 32 kiB of flash.

A relatively high-end microcontroller, thus 8-bit RISC. Still in production as of 2021, but the newer ATMega32A is also available.

Tag [avr], and don't tag [atmega32] unless your question is about specific features or performance of this microcontroller. (You can still mention in the question body what hardware you're using, even if it's probably a general AVR question)

Specs

https://www.microchip.com/en-us/product/ATmega32 links a summary datasheet: https://ww1.microchip.com/downloads/en/DeviceDoc/2503S.pdf and various more detailed stuff.

  • 32 KB ISP flash memory with read-while-write capabilities
  • 1 KB EEPROM
  • 2 KB SRAM
  • 54/69 general purpose I/O lines
  • timers, USART, 8-channel 10-bit A/D converter
  • 0 to 16 MHz (or 0-8 for the ATmega32L model)
  • Supports AVR's multiply instruction with 2-cycle performance

Check number range in Preprocessor macro

To set the clock prescaler on the Atmega32u4, you have to set TCCR0B according to this table: If you want the prescaler to be 64, you would write this: TCCR0B |= BV(CS01) | BV(CS00); btw, here is BV(): #define BV(x) (1<
