Arduino Nano 33 IoT Support #384

Open moooorph opened 3 years ago

moooorph commented 3 years ago

Arduino Nano 33 IoT (Arm® Cortex®-M0 32-bit SAMD21) support requested due to identical issues with Nano 33 BLE while using the onboard WiFi/BLE (u-blox NINA-W10) -> interrupt issues with standard methods, PWM requested (see NeoNrf52xMethod.h)

Tested with: NeoPixelBus 2.6.0 + Arduino Nano 33 IoT + ArduinoBLE.h and standard Arm method (NeoArmMethod.h) LED output deactivated: BLE working / LED output activated: BLE no connection possible (interrupts/timing)

This will require specific hardware support for that platform. The ARM support is a bitbang method and will be interrupted by lower level services like BLE and WIFI as you found out.

I do not own one of these boards myself.

@moooorph I got a Seeeduino XIAO for a holiday gift, so I am now actively working on it. If you are interested in testing it on the Nano 33 IOT let me know. I am working on i2s method first. Then probably a i2c method. The PWM feature looks heavy interrupt based so that will be the last method I will look into.

@Makuna excuse my delay. I decided to swap my project to an ESP32 platform (multiple reasons) and can use RMT now which is my most preferred solution acc. the described timing issues. Anyway I could try to test your XIAO methods with the Nano IoT
