Serial Display sample for Arudino Nano 33 BLE powered by nRF52840 chipset

[nagesh.shamnur]

Hi Support team,

    I have downloaded nRF5 SDK and found that there is a sample for serial via UART but however the samples (<SDK Folder>\examples\peripheral\uart) is available only for PCA series of hardware which are directly released by nordic. But i am looking for Arduino nano 33 ble which is powered by nRF 52840 SOC. (i checked <SDK Folder>\components\boards i don't see arduino nano 33 ble listed). Can you help me with that?

Basically i want a baremetal example (not involving either zephyr or mbed ) which i can use for bringing up the Arduino Nano 33 BLE board and print hello world on the COM port. I found one such example for nRF52832 in the link: https://git.threefortiethofonehamster.com/kelvin/spider-bot.

Thanks in advance.

Regards,

Nagesh.

This is a third-party board, which means that you should contact the makers of that board. We are limited to what we can support on this platform.

This example should be a good start.

Thanks a lot for the quick and kind reply. Let me check on that.

Hi Jared,

    When i checked SDK folder under components/boards i see presence of arduino_primo which is now discontinued. Can this folder be updated with currently supported models such as Arduino nano 33 ble ?

You can add your own custom board file by mapping the pins yourself.

Hi Jared,

   Tried as suggested by you, but i am kind of stuck trying to get baremetal UART and USB CDC_ACM up and running. Can i get a helping hand here ?

I am using nRF5 SDK 17.0.2 for Arduino Nano 33 BLE MCU.
