@kuriko Thank you

Thanks ajb2k3,
I did manage to get my Stamp Pico working with both a PIR sensor and relay unit.
The problem was my fault. In soldering on the grove connector to the Stamp Pico, I soldered it on the wrong side of the board so when I connected a grove cable - ground was connected to GPIO 33, 5v was connected to GPIO 32, GPIO 32 was connected to 5v and GPIO 33 was connected to ground. Fortunately I didn't cook my board.

@felmue said in Stamp Pico and connecting more than one unit:

PIR unit only needs one input GPIO and the relay unit only needs one output GPIO.

Thanks felmue I did get this working.

Thanks robski, yes indeed this was my problem. I hadn't updated my Atom S3 Lite with the latest firmware via M5Burner.
When I updated it to V2.0.1, the same as the latest UIFlow 2 version, it worked perfectly.
Thanks for your help.

@kombistack
oooF! Sorry, I am not familiar with UIflow!!!
Cheers!

@ajb2k3
Thanks for the advice but I am hardly going to buy a shop brought SPO2 meter to check the M5 Heart Rate unit against.
Calibrating the unit?? No instructions were provided with the unit to do this.
I persisted testing it on myself many times and there is no way my heart rate fluctuates between 60 and 210.
Anyway M5Stack guys were helpful in trying to assist me too so that was also appreciated.

Nope but if you read the data sheet for the SPo2 then it says it needs calibrating.

Hello @Kombistack

from what I can tell the damage isn't that severe. According to the schematic those two components are capacitors. I don't think they are critical for the overall functionality of the M5Core2, they might have an influence on the performance of the IMU though.

That said, you should be able to resolder those with a small soldering iron. Or find someone who can fix it for you.

I don't know if this board can be purchased separately as spare part. Have you checked with M5Stack support?

Thanks
Felix

I fixed the problem with the cam2core on the core2. So the UnitCam will work with Arduino IDE code and the core2.

It is a very simple fix:
Replace the first line #include <M5Stack.h>
with #include <M5Core2.h>

Initialising the core code on a Core2 is not the best idea!
Now it works on my Core2 showing the video stream from a UnitCam connected to PortB (pins 26, 36).
