The previous question seems difficult to solve, so I decided to change to another question to learn. I looked at the 38 decoder, which is roughly 3 inputs and 8 outputs. The decoder is usually used to...
It is said that the CAN in STM32 has a high rate and a long transmission distance. However, during the debugging process, I found that due to the capacity of the receiving FIFO for three data frames, ...
As the title says. Wince5.0 platform. My battery driver uses GPIO to simulate IIC, and gets the voltage and current power value by reading and writing IIC. The battery driver is repeatedly called by t...
