Thanks to all your answers to my questions, my project has become very easy.
Today's question is the same as the subject : low drive, Low frequency I/O
During my c program, I am in the process of pin assignment and learned about "low drive, Low frequency I/O "
In 52832 datasheet, there are 10 pin of "Low drive, low frequency I/O only" from P0.22 to P0.31.
and I was able to check the following information.
- Low frequency I/O is a signal with a frequency up to 10 kHz.
- Radio performance parameters, such as sensitivity, may be affected by high frequency digital I/O with large sink/source current close to the Radio power supply and antenna pins.
So I checked that "low drive, Low frequency I/O" is a port related to radio, or rf communication.
in my project, I don't use rf, rf communication and NFC. I only use ble as beacon receiver.
what I'm wondering is that it is possible to assign this low frequency I/O with gpio pins such as led on/off or switched on/off?
