This is the schematic diagram of the board I drew, using STM8S003F3, using IIC to read and write 24C32, with a pull-up resistor of 3.3K. I used another STM8S003F3 development board with the same progr...
I just submitted a smart bike companion, and later found out that someone else has made one. In order to make a SensorTag for fun, I submitted another solution. Since the difficult ones have been done...
Everyone knows that if you want to learn any kind of MCU or MPU, you need to actually write programs or build hardware. However, some MPUs or MCUs are not suitable for building circuits by yourself, s...
Difference between TMS320x281x and TMS320x2833x/TMS320x2823x
I've been using TI's 28355 chip recently. Since I've never used it before and there isn't much information on it online, I went to TI's off...
