Can nRF52840's all pins work uart?

[swna3708]

Dear all.

I know the nRF52840 has 2 uart module.

I've been used only 1 uart setting like below pin connecting in 52840 DK reference doc.

But now i have to use 2 of uart which 52840 has

So what my curiosity is Can nRF52840's all gpio pins work uart? 

I want to use both of them.

e.g. if uart0 is set like p0.09, p0.10, p.0.11, p0.12

and uart1 is p0.13, p0.14, p0.15, p0.16, Am i using correct?

Also, for this, all I have to do is changing RX_PIN_NUMBER, TX_PIN_NUMBER and connecting with pins i want to use

and add some of code to set another uart?

 

thanks.

best regard.

I also need two uart but can't work。

#define RX2_PIN_NUMBER 27
#define TX2_PIN_NUMBER 26
#define CTS2_PIN_NUMBER 12
#define RTS2_PIN_NUMBER 11

#define RX_PIN_NUMBER 14
#define TX_PIN_NUMBER 16
#define CTS_PIN_NUMBER 7
#define RTS_PIN_NUMBER 5
#define HWFC true

Hi

I would suggest opening a separate case on this issue. 

Please provide a bit more information on your issue, how you configure the UART interfaces, which errors you see etc. 

Best regards
