DFRobot_HX711_I2C connect to MKR1010
jeroendegroote 2022-07-12 03:32:45 1754 Views1 Replies Dear,
I am struggling to connect my DFrobot HX711 to a MKR1010 via I2C. I am following the guidelines documented there; https://wiki.dfrobot.com/HX711_Weight_Sensor_Kit_SKU_KIT0176
This describes the process for implementing the gravity I2C 1kg weight sensor kit (KIT0176). This is the exact kit I bought. When running the example sketch ‘getCalibration’, I don not succeed in compiling it for an MKR1010, nor for an Arduino Uno.
i get the following error:
"

^~~~~~~~~~~~~~
exit status 1
Error compiling for board Arduino MKR WiFi 1010.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

As far as my understanding goes, my best guess is that something is wrong with setting up the I2C address at the start of the sketch. I did not change anything in the example sketch. However, I am unsure if this could be why the sketch does not compile. Could someone point out what the potential solution could be?
Thanks in advance!!

HI
Sorry for the late response
The demo code on Wiki do not contain #define HX711_I2C_ADDR (0x64) sensor IIC address*/ now, maybe it has been updated.
Could you please try the demo code of new version again?
Hope it will help.
