I have an accumulator. When signals a and b are updated, a is added to b and then accumulated. I want to use active to determine whether the signal is updated. If (a'active and b'active) then the mach...
The current key tone is what was used when the kernel was generated. I want to change it to a different sound. How can I change it? Where is this sound file hidden? Has anyone changed this key tone fi...
I used Wanli's demo board EK-STM3210E, and the compiler was MDK.It's best not to use the board's emulator ST LINK II. A lot of inexplicable crashes were annoying.Many of them died in HardFault_Handler...
I recently got a prototype for measuring PM2.5 and I just couldn't figure out the principle of signal collection. Since the front-end chip model of the machine has been erased, I can't get the circuit...
