Missing sample code for Feather 32u4 Arduino board about embedded-uart-sps

[rnestler]

According to https://learn.adafruit.com/adafruit-feather-32u4-basic-proto?view=all#logic-pins-2-9 it looks like you can use pin 0 and 1 with Serial1.

Then just use Serial1.begin() and remove the pinPeripheral calls.

I changed all the references of Serial2 to Serial1. But I am getting the following error in sps30_example_usage.c :
/tmp/ccTGaACo.ltrans0.ltrans.o: In function main': /home/dinesh/Arduino/libraries/sps30-uart/sps30_example_usage.c:61: undefined reference to sleep'
/home/dinesh/Arduino/libraries/sps30-uart/sps30_example_usage.c:119: undefined reference to `sleep'
collect2: error: ld returned 1 exit status
exit status 1
Error compiling for board Adafruit Feather 32u4.

Arduino just compiles all files it finds which is a bit suboptimal in this case. You'll have to remove sps30_example_usage.c, I'm assuming you're using some kind of .ino file. You can use the example as a base for what functions to call on the generic sps driver..

I don't know which is the correct serial interface to use for which pins on your board since this is very platform specific. For general Arduino programming support you'll be much better off asking in an Arduino forum. But once you get it working, we'd be happy to include your findings on how to get the example working for your board. I'll leave the issue open for a while.

Thanks, I kinda figured that out. I removed the sps30_example_usage.c file. I then added
#define NULL 0 in sps30.c .
The program is now compiling without errors. There is a problem with interfacing it to the hardware. I will update any progress.

@nit1995 did you get it working? If so, would you provide us with a sample or post a pull request?

[rnestler]

@nit1995 Do you have any updates?

[nit1995]

@rnestler Nope. I stopped working on the project. Instead of Feater, we integrated it with another microcontroller.

@nit1995 I'll close this for now. Feel free to re-open or open a new issue if you encounter any problems 🙂
