Make-Yourself ATmega32 Starters Kit with LCD I2C SPI RTC ADC interfaces

Posted on Feb 6, 2014

Here is my home-made kit of ATmega32 microcontroller interfacing. The ATmega32 controller is rich with features like onboard 32kB in-System programmable flash, 1 KB EEPROM, 2KB SRAM, 10bit ADC (8 channel), SPI bus inteface, TWI (compatible with I2C bus) interface, an USART, analog comparator, etc. That`s why I`ve selected it to load my kit with al

l those features. This M32 card is having an LCD inteface with contrast adjustment, an RS232 port for connecting with PC, a connector for 8 analog voltage inputs to measure by ADC, a Real Time Clock IC DS1307 from maxim with battery back-up, four general purpose keys, two keys for generating interrupts and an LED. The PCB is completely home-made, using the etching technique with the Ferric Chloride chemical.
