    • RE: Accessing second UART on M5Stamp-PICO

      Hi Felix,
      Sorry for the delay... my STAMP_PICO project was momentarily shelved but I just resurrected it and found your response.
      I will definitely try your suggestion since I would like to keep the native port to flash but I need another UART.
      Thank you!

    • Accessing second UART on M5Stamp-PICO

      Is there a way to access a second hardware UART on the M5Stamp-PICO?
      I do not need the SPI port but I do need the UART (and I2C) and uploading code while also using the UART in the application is really inconvenient.
      Any help appreciated.

    • RE: new m5stack: Failed to write to target RAM (result was 01070000)

      I had weird problems like this with an M5Stamp-PICO until I put more capacitance across the bus (5V and 3.3V). I used a couple of tantalum capacitors I had on hand, not sure the value, probably 33uF. I was powering the device through the USB serial adapter and apparently it was power limited.
      I have had no problem whatsoever since then.

    • RE: M5Stamp C3 - I2C interface

      Thank you, that is good news.
      Now I just have to find out how to configure and access it from the Arduino IDE :)

    • M5Stamp C3 - I2C interface

      Does the M5Stamp C3 have an I2C interface? I do not see any reference to it on the pinout.
