LP-CC2652RB: Enable both UART on LP-CC2652RB

Part Number: LP-CC2652RB
Other Parts Discussed in Thread: CC2652RB

Dear,

In ZNP example source UART0 was used communicate with host MCU, So I need enable other UART port to print out some debug.

I can not find mux pin function tables of CC2652RB so I don't know What pin I can use. When I import UART2echo project from Resource Explorer and check .sysconf file, UART pin was UART0, not UART2.

So Could you please send me some instruction how to enable UART2 on ZNP source to print out debug ?

Thanks,

Khai.

There is no UART2. Since NPI UART uses UART1, your second UART can only use UART0 and I see not problem on this.

Dear Chen,

UART config in ZNP project in picture below :

I don't understand "NPI UART uses UART1" clearly. So if I want use uart0 how can I config sysconf file ? And what's DIO pin I need to use ?

Thanks,

Khai.

I try to use default UART2 configuration in sysconf and I can output debug message with it.

Dear Chen,

I already print out uart log by using "display" config with UART0.

Thank you.

Khai.
