SD card reading and writing problem, some files can be written in, some files cannot be written in...
As the title says, SD card reading and writing problems, some files can be written in, some files cannot be written in... Experts can give me some advice, the file system uses EFSL ARM7---EasyArm2200
DCDC input end inrush current problem
I recently used this DCDC circuit. When VIN is powered on, the impact current at the input end will range from a few A to tens of A, and the size varies with the resistance value of R1R2. I soldered t

Non-blocking assignment order problem
This simple program can realize the function of 3-8 decoder, but I don't understand the order of the two non-blocking assignments in the begin block. According to the simulation results, the first Q a
How can we read RSSI correctly without affecting normal data reception?
I am using CC1020 to make a data transmission module. When receiving data, I need to read the RSSI value. The data reception is done in the external interrupt. The problem is: the RSSI value I read wh
