Tool/software: Code Composer Studio
Hello!
I'm using the Rm46L852 at home for a simple project. But i need 3 UARTS for this project, the RM46 only got 2.
Is there an easy way to configure GPIO's as an UART? I've heard there are so called Software UART's. Do you have an example for that?
Greetings
Hello Kubiks,
It is possible to implement a UART through "bit banging" IO, but I wouldn't necessarily recommend it. The easiest way to implement another UART on the Hercules device is to use the N2HET to emulate one.
Here is some example code for the N2HET UART emulation: 7462.N2HET_EMU_SCI.ZIP
there is also an unpublished application note on the subject as well. Here it is: 8883.N2HET_EMU_SCI_AppNote.pdf
And finally some links to other posts about the same topic:
