Hi, I was wondering if it is possible to use the on-board USB-to-UART bridge, for serial communication using, That is, I've created a test board connecting GPIO20 to USB-D+ pin and GPIO19 to USB-D- pin, which should allow USB 2.0 OTG / USB-JTAG bridge. https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/gpio.html I would appreciate your help, if you already have experience with this topic. |
