I successfully used CPLD to drive MAX7219 to transmit 16-bit parameters.
I see that microcontrollers transmit 8 bits of data at a time, and I also want to use CPLD to transmit 8 bits of data.
But ther...
I'm working on car charger (27W) and wireless charger (maximum 15W) recently, but I can't pass EMC (radiation and conduction). What bothers me most is that I don't have a good design circuit for the f...
Using a 220V to 18V transformer, the voltage output of the transformer output (pins 12, 14, 17, 19) is 12V. After passing through the MB6S rectifier, the output voltage of pin 3 of SP1 is 27V, and the...
