I use the stm8s discover development board, that is, the MCU is stm8s105c6t6 [size=5][color=Blue][b]For a chip like stm8 that has a separate IO port direction, how should it be set to release the bus?...
I use an emulator to debug the dsp,but it stops downloading programs after about a week of use.The error message is something like power loss.Is the dsp not that easy to break, or is there something w...
The program to read this part looks like this:
char READ (char addr)
{ char R;
SEN=1; //Generate start bit
while (SEN==1); //Start bit detection completed
IIC_SEND(0b11010000); //The SSPADD of the sla...
The program I wrote means to draw a sine wave first, then outline the sine wave, then draw the same sine wave on the left, and outline it again... The method is very stupid, and there is a flickering ...
I have 20 TMS320F28379DPTP (176 pins) chips on hand. The only difference between 28379D and 28377D is the position control module. The other hardware and software are exactly the same, so the software...
