I shall take a look thanks!

Steve

I've checked all three port types so it's easy to see where everything is but I can't see how to get the SCK line into a plug-in module (not base) via say port A (red).

Steve

OK, thanks.

Steve

That worked thanks! Any other gotchas likely? Also, is there an M5 stack CoreS3 api guide? I couldn't find one anywhere.

Steve

Hi

The output is a DOUT as the module contains an HX710B A/D converter. Really simple to use with for example on an Arduino IOT 33 SCLK goes to SCK, DOUT going to any digital in pin and vcc,ground. The only connection I cannot work out is how to connect to sck from an external unit.

OK, I've now added the library but I am now getting 'fatal error: BMI270_Sensor.h: No such file or directory
#include "BMI270_Sensor.h"' when I compile any of the test programs. I've loaded the BMI270 library but I suspect the Arduino one is not the correct one. Any ideas?

Steve

Hi

I did, yes but it seems to not exist. I found the library but I do not know how to add it in to the Arduino IDE.

Steve

Hi. I am indeed. The part is from China (https://www.ebay.co.uk/itm/193482839640) and uses the HX711 library.

Steve

Hi.

I have a Core S3 and am programming it with the Arduino IDE. When I compile I get

*D:\Users\steph\Arduino\SPG\Gloving\Gloving_Pressure\Gloving_Pressure_M5StackCore23\Gloving_Pressure_M5StackCore23.ino:6:10: fatal error: M5CoreS3.h: No such file or directory
#include <M5CoreS3.h>
^~~~~~~~~~~~
compilation terminated.

exit status 1

Compilation error: M5CoreS3.h: No such file or directory*

I've added the M5Stack board and in the preferences too. I must have missed something somewhere as the Core S2 works fine. Any ideas?

Steve

Hi

I have the tube pressure sensor connected to port B on an M5stack Core 2 using the M5GO Battery Bottom2. All works OK but the resolution/range is not fine enough for my project. I do however have another little circuit board I was using on an Arduino IOT 33 that I'd like to use. It's a simple unit that only requires VCC,GND,SCK and OUT. I'm hoping to put it in an external unit and plug it in. All seems pretty easy apart from SCK. How would I get that signal to an external unit from the M5?
