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...
I want to realize continuous AD conversion of two channels, but I don't know DTC. I want to realize it by my own programming, but there is only one AD conversion result, and only the highest channel c...
I have four CC2530s and want to build a star network. I have seen the ZigBee protocol stack for a week and want to make CC2530 a serial port transparent transmission module. One coordinator, three ter...
