UART pinout for vcp is incorrect #5

Closed allexoll closed 2 years ago

allexoll commented 2 years ago

currently dir_vcp_rx/tx is on gpio25/24, and vcp_rx/tx on 18/19.

The issue is that 18/19 only have cts/rts capabilities on the rp2040, but not rx/tx.

but gpio24/25 have uart1 rx/tx capabilities:

i think just switching the two pinset would be enough for VCP to work. I currently have a start of impl for the vcp (using core1 since DMA has not yet landed in the hal), but it will need the correct pins for this to work.

Hi, thanks for reporting!

I have moved the pins to 20 and 21 in the latest commit: image
