G2553PWM

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, so I have to software spi ,but the software spi configure have low speed into hardware spi.
