usb_host

[mrbbp]

Sorry for this newb question, i read your code, but i do not see what i want. I just want to connect trough usb a pico to a thermal printer.
what do i need to just software connect to printer?

i do not understand the need of usb_host_Pin!

[SYSTEM]
USB_HOST_PIN_DP = "GP26"   # required for USB printer(s), specific to board; GP26 is a PicoW specific pin name
USB_HOST_PIN_DM = "GP27"   # required for USB printer(s), specific to board; GP27 is a PicoW specific pin name

i don't need to create an http/mqtt server, i just want the pico to be able to print sentence coming from pico with few ESc/POS instructions...

regards

Hi, the Pico doesn't have USB-Host support, so circuitpython 9 implements USB host support using the RP2040 PIO - which provides USB host using two GPIO pins. My implementation allows for these two pins to be configurable, so that's why USB_HOST_PIN_DP and USB_HOST_PIN_DM are there.

So you want to simply print some sentences, what would trigger these to be printed (you probably don't want an endless loop of printing those sentences)?
