QTPY RP2040 Board not found

[TrinityTeacher]

I just got a QTPY RP2040 and I am unable to get the port to show the device. I tried installing the board but do not see it anywhere. I can see the QTPY SAMD21 but that board doesn't work. Any help would be appreciated.

I am using the QTPY to hook up temp/hum and light sensor with an OLED all in I2C for a portable package. This will be used by students to gather data on experiments.

Hi @TrinityTeacher

@TrinityTeacher

I can see the QTPY SAMD21

In this specific case, if you are seeing it somewhere in the Arduino IDE user interface, a screenshot of the IDE window might be helpful.

@TrinityTeacher

that board doesn't work

Please provide a detailed explanation of what you mean by this, including:

• What did you do?
• What were the results you expected from doing that thing?
• What were the results you observed that did not match your expectations?
  • Make sure to include the full and exact text of any error or warning message you might have encountered.

Have you installed the board library for RP2040?
As @ptillisch has said a screenshot would be helpful.

RP2040 are 3.3v only to.
Better off using a 5v board?
Unless you are using this with careful students or have other circuitry.

Thanks... Here is what I get when I search for boards. QT is not listed but the the rp2040 is.

OK, it is clear now. I'll provide instructions for installing support for your "QT Py RP2040" board in Arduino IDE:

1. Select File > Preferences from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Enter the following URL into the "Additional Boards Manager URLs" field of the "Preferences" dialog:

   https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
   

   If there are already Boards Manager URLs in the field, separate them with commas.
3. Click the OK button in the "Preferences" dialog.
4. Select Tools > Board > Boards Manager from the Arduino IDE menus.
   A "Boards Manager" dialog will appear.
5. Wait for the updates to finish, as shown by the messages printed at the bottom of the "Boards Manager" dialog.
6. Scroll down through the list of boards platforms until you find the "Raspberry Pi Pico/RP2040" entry. Click on it.
   Some buttons will appear on the entry.
7. Click the Install button on the "Raspberry Pi Pico/RP2040" entry.
8. Wait for the installation to finish.
9. Click the Close button on the "Boards Manager" dialog.
10. Select Tools > Board > Raspberry Pi RP2040 Boards > Adafruit QT Py RP2040 from the Arduino IDE menus.
