Hey! I was wondering if you could help me out with some issues I seem to be having with whats coming out of the TX line. So I'm following along for the FPGA-peripherals/uart-tx/examples/txstr/
and i got everything working but when i read the serial data, instead of "Hello!.." I get a bunch of garbage ascii. I'm assuming this could be because of the fact that your
baudgen.vh
file was generated for a 12Mhz clock.I used your python script for what it shows my clock speed is at 50Mhz
But for some reason I'm still getting garbage ascii, with `define B115200 434 i am getting the correct amount of chars printed out in the terminal which is progress but I can't seem to figure out what else I'm doing wrong. I'm using the manual off here https://usermanual.wiki/Document/ax309xilinxspartan6developmentboardusersmanual.1355685398.pdf
RESET pin is at L3
TX pin at D12
CLK pin is at T8
Is it maybe something with my constraints file that I would need to add extra for the TX or CLK pin. Or something off with how the baud is being calculated?
Heres my ucf file
Thank you!
