一个简单的MEGA8初始化程序，很实用。包括外部中断，定时器，SPI和UART初始化-MEGA8 a simple initialization procedure, it is practical. Including external interrupt, timer, SPI and UART initialization

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, s
