Serial Lib Tutorial

Using Arduino Programming Questions
#1

Hello

I am using Adafruit Feather M0 Adalogger an need three serial channels beyond the USB channel (4 all total). The channels are MU 10DOF (SCL & SDA), GPS Module (TX Pin 15 & RX Pin 14) and a Radio TX (Pin 10).

I found some time back a tutorial that explained how to set up the serial channels. I had a machine crash an lost the tutorial, so I was wonder if any one could guide me to that tutorial. Or help me with the code for the last channel (Radio TX Pin 10).

Thanks

The IMU is NOT a serial device.

the IMU is the 10DOF-IMU MPU9250+BMP280. The attached pic shows the hook up pads.

Your point being? SDA and SCL are I2C pins, NOT serial pins.

Any RX or TX on there :wink: No, SDA and SCL which is I2C bus.

From the datasheet, the processor has up to 6 SERCOM peripherals that you can use for different communication purposes.

Looking at the schematic, an number of those SERCOMs are still available.

Maybe Creating a new Serial is what you're looking for.

My point is they might be I2C pins, I can not use them to send data to the radio. Meaning I have to create a new serial port for the Radio TX channel.

Thanks sterretje :slight_smile:

I think that's what I am looking for.
