UART1 Q26xx Interface - Transciever


#1

Hi.

Sorry, but i’d like to know if all 8ch are in use for testing application, like Eclipse IDE, firmware downloading, debug, etc.
Or is just necessary a Transciever with 4chs (RTS, TXD, CTS, RXD). I intend to use only C languagem using de ADL applications from Wavecom.

Another question is GPIO Q26 UART1. In PTS manuals, you say that pinouts are 3.3V tolerant and in CDG manuals you say pinouts are 3V tolerant. Which is specification is recommended. i’d like to use a 3.3V transciever em UART1.

Best Regards.
