-- Once you get an address, this will be in decimal and not hex. 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!

 Printing is simple :lcd.putstr("") This requires a string input! if you want to feed a changing value such as a temperature, it must be: lcd.putstr(str(Variable))

 OSERROR : 5 (This is quite a common error, 5 means I/O error. Check Your connections. This means codes can't be sent or recieved ensure SCL and SDA are properly connected through the level translator!
