You can convert the decimal to hex or simply put a decimal address in the setup. +- Once you get an address through the console (REPL), this will be in decimal and not hex. You can convert the decimal to hex or simply put a decimal address in the setup. in my case, the decimal addr. was 39 which converts to 0x27 in hex. - Ensure that your SCL and SDA pins are selected properly in accordance with the Pico's pin table. These connect to the low voltage side of the translator with a 3.3V Reference from the board. The high voltage side gets a 5V reference from the VBUS pin of the Pico. - Finally, assure the I2C_NUM_ROWS and I2C_NUM_COLS are set properly!
