In the process of DIY ultra-low power clock, we have discussed the clock source.Does the clock source used by this clock use a 32768Hz crystal or a dedicated clock chip such as DS1302?Finally, we chos...
I can't help it, answering questions for the first time. In 2008, my company debugged a new arm9 CPU from Samsung, model S3C2416, which is a simplified version of S3C2450. When the development board w...
I have been able to log in the module to the network and get the module's IP address, but when I use BENQ M32 AT$DESTINFO to connect to the server, an error occurs. I don't know what's going on? AT+CG...
I don't know what happened. This is my first time to make an SD card, but I encountered a big problem. I tested the program with ADS bare metal without any problem. But it doesn't work under PB (Micro...
