[SOLVED] Multi UART Communication

[TiagoRibeiro]

Hello, I need to develop a project with PIC18F4680. Pic needs to communicate with a GSM module and GPS. But this pic has only one USART. So I have a doubt, it is possible to make 2 or more UART for Software? IF YES, how? Please guide me or provide any app to read.
I'm using MPLABX - C18 Compiler.
Thank you.

Google with the term "Soft UART" you will find tons of information

Hello again,
I managed to make a software UART work, but she is sending garbage.
I think this is happening because the baud rate is not correct. :grin:
Anyone know how to set the baud rate of the UART software?

Use PIC18F46K22. It has 2 UART.

you can find setting baudrate in to registers in the reference manual . Normally everyone does set at 9600 mbps.

if u are sending different commands for different devices then u can connect multiple serial port to single port. But condition is different data should be for different devices.
This is not try but u can try and post the resullt.
