Openplotter 3 - I2C - Your Raspberry Pi is too old
#4
I just installed Openplotter on a new computer and got the same message in the status bar of the I2C app. As a result I cannot add my sensors.  Sad

Hardware:
  • Raspberry Pi Compute Module 4 Wireless / 8 GB RAM / 32 GB eMMC
  • Waveshare CM4-IO-BASE-B baseboard rev. 4
  • Waveshare 8inch DSI touch display
  • BMP280 sensor 

I2C seems to be working, sensor is shown at address 76

Code:
pi@openplotter:~ $ sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- 76 --
