When Using RP2040, it must using the hardware UART instead of software entity.
Doing so, you'll need to modify the pins_arduino.h, which you can edit locally.
according to the datasheet of pico, I modified as follow:
Be attention of the WIRE0, as it connot be comment and I didn't change it. so if you want to use I2C, use WIRE1 instead.
wire.begin() // do not use it
wire1.begin() // yes
So, For Indicator, RP2040 connect to PC via USB2.0, Serial1 to inner ESP32 and Serial2 via grove(20,21).
Serial2 will support the high speed baud, as now it's harware configured.
There are two problems:
