HRSout problem

[joesaliba]

As per the title, I spent around half a day with this HRSout on an 18F26K22. I think I never used HRSout on this device, and really I do not know what is going on.

At this time I am only doing some tests to a data terminal on a PC. As far as I know I set everything with regards to HRSout, however, the data that is going to the terminal is garbage.

After external oscillator, internal oscillator and had spent some good amount of time on this, I thought to replace HRSout with RSout to give it a try, and it worked!

So please, where am I missing the correct setup to make the hardware USART work as it should be?

Thanks Pepe,

Seems to be working. It was something to do with BAUDCON. I will investigate which bit I altered to make it stop.

Looks that I was forcing BAUDCON.3 to use BRG16 at 16-bit Baud Generator, but it must have been 8-bit Baud Generator.
