Hi.
Tell me, I need to do remapped USART 1 and USART 2.
Usart 1 - RC0 (Rx), RC1 (Tx)
Usart 2 - RC5 (Rx), RC6 (Tx)
Can I do it? Or I need to use for USART RC6 (Tx) RC7 (Rx). If you can tell me a sample code.
Thanks in advance for your help!

Re: Remapped USART PIC18F47J53
Hello,
If you open datasheet of your MCU, you can see that you cannot remap USART1, but you can remap USART2 (UART_Remappable)(Page 156, Table 10-13).
http://ww1.microchip.com/downloads/en/D ... 09964C.pdf
In this document on page 4, you can see that RC5 pins cannot be remapped.
Also, if you remap USART2 on RC6, you cannot use USART1 and USART2 at the same time, because USART1 uses RC6 pin for Tx.
In the attachment, you can see a simple example, where USART2 is remapped to D5 and D6 pins.
Kind regards,
Jovana

Re: Remapped USART PIC18F47J53
Hello. Thanks for your help.
How to make remap USART2 I understand. It will work on pins RD4 and RD5. But I can't understand if I can remap USART1 and how to use it after that? After reading the first post moved new pins USART1 RB6,RC2. It is necessary to make remap USART1 and USART2.

Re: Remapped USART PIC18F47J53
Hello,
As I said in my previous post, you cannot remap USART1. You have to use RC6 (Tx) and RC7 (Rx) if you want to use USART1.
You can read more about this in the datasheet on page 155, where also you can find this:
The MSSP1 and EUSART1 modules are not routed through the PPS module
Kind regards,
Jovana
