ESP32 and QMC5883 and HMC5883 not compiling

[mkopitovic]

Hi flowcode community

If I add QMC5883 and HMC5883 components I get an error and I can not compile anymore.

"Device: ESP.ESP32.ESP32_WROOM_32

Thanks for letting us know, hopefully sorted for you now via the library updates.

Hi
thanks for the fast response,
but unfortunately there still error during compile
"C:\ProgramData\MatrixTSL\FlowcodeV10\CAL\ESP\ESP_CAL_String.c:113:17: warning: 'FCI_GETCHAR' defined but not used [-Wunused-function]
static MX_UINT8 FCI_GETCHAR(MX_STRING sStr1, MX_UINT16 iStr1_len, MX_UINT16 iPos)
"
best regards

Hello,

That just looks like a warning and shouldn't cause a compile error. Can you post your project or at least your .msg.txt file so we can see the errors you're getting.

Thanks again,

This was the error.

../main/esp-project.c: In function 'FCD_049a1_QMC5883_Magnetometer1__UpdateCompassData':
../main/esp-project.c:272:66: error: pointer targets in passing argument 3 of 'FCD_049a1_QMC5883_Magnetometer1__Read_N_Registers' differ in signedness [-Werror=pointer-sign]

Hopefully that one resolved for you now too.

hi
sorry to bother you but I ran into a few more bugs trying to make a compass:
1: LSM303D_Magnetometer1 component also don't compile,
2: EBM015 component also don't compile,
3: LSM303DLHC1 don't have Read_bearing, Read register and collectXYZdata but compile normally in this moment I can't confirm that component work.

thanks

Please post your project so we can see where the problem is.
