@felmue said in Stamp Pico USB Serial:

Or in other words, there is no way to directly connect D- and D+ from the USB-C breakout to the M5PicoStamp.

Hi Felix,

thanks alot for that information.
Was hoping this converter could be easy be done by some ICs and restistors maybe but would be too difficult for me yet.
So i think i will get another controller with built in or a cojntroller with onboard USBC connection.
Makes no sense to spend much time and money if the device will be procudes 100 times each with MCU and a serial converter.

Your help was great!!!

Best regards

Hi Felix,
@felmue
sorry for this confusion.I tested to connect Tx0,Rx0,D+,D- but the USB wasnt recognized by PC. So there was no chance for me to initialize the com port to establish the connection.

I also tested to change D- and D+.Same result.
I must have done something wrong^^

Best regards

Hannes

Thanks Guys!
I was hoping to get the connections (0,) G1 and G3 modified to be used as serial only after the programm was "burnt"
I dont need a complete build in USB only the serial connection for data transmition.

All of the other s connections are perfect for my project with 2 DACs and more than 2 ADCs.
Additional components wouldnt be a problem. I have enough space on my SMD layout...

Hi ,
im testing the Pico to create a standalone measurement device with 2 ADC and 2 DACs.Before i was using MCUs with internal USB but now i want to create a separte USB serial connection only to transmit the measurements to the PC and receive some settings from the PC.I can use the burner to transmit the program but i do not know how to create an additional serial.Where can i find a example code which is running on the PICO and where do i have to connect the D+D-?An additional USBC breakout board is available. Hope anybody can help me to get started. Best regards Hannes
