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...
Problem description: Industrial field control, real-time performance is very high, using Advantech industrial computers as the host computer, requiring that when one of the industrial computers fails,...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
