If you keep messing up the "comma-separated" file prep like I do (the SAVE feature from Open Office is not smooth), consider using a script if you are I.S. savvy.
If you connect a logical analyzer to the serial lines, you know for sure if data is being transmitted or not. That would have saved you a lot of time. I always put in my PCB designs a testing point...
Okay, I think I might have solved this one. I didn't have the TRIS of the transmit pin configured as an output. I was under the erroneous impression the UART controller trumped control of any port...
I was originally planning on making 2 sets of MCP23017 circuits; 1 for input with debounce, 1 for output. But even with JLCPCB it comes out to $1 / PCB. I'd like to lower my cost more, and not have...
Use a logical analyzer to see what's coming out of the chip. Compare the output of the SEROUT2 to the output of the HSEROUT2 using the logical analyzer. You might think that your output is 115200,...

Re: Filtering noise from a wire
The graph at the bottom of page 1 of the LTC4311 shows a total rise-time of about 1uS.

Would a LTC4311 be enough...
