Missing declaration of VL53L1X ULD (STSW-IMG009)

[Dn1te]

Hi everyone,

I am a beginner working with the VL53L1X sensor on an STM32F103C8T6 using the STSW-IMG009 (Ultra Lite Driver). I am trying to implement a calibration routine, but I am encountering two specific compilation errors inside my VL53L1X_calibration.c file:

The errors:

1. 'VL53L1X_ERROR_TIMEOUT' undeclared (first use in this function); did you mean 'HAL_DMA_ERROR_TIMEOUT'?

2. implicit declaration of function 'VL53L1_WaitMs' [-Wimplicit-function-declaration]

I have checked the driver files but cannot find their declarations.

I have not changed any of the driver files. Am I missing something? Any help is appreciated. Thank you!

Hi:

I just downloaded a new one STSW-IMG009 and compile again, actually there are no errors or warnings reported.

and I also check VL53L1X_ERROR_TIMEOUT is declared in VL53L1X_api.h. we add this timeout just for make sure sensor can't stuck here by some unstable environment (for instance, if a cable or a sensor breaks for some reason).

In addition, VL53L1_WaitMs , there is no problem with the function declaration and definition.

you can download a new one from www.st.com and try again, make sure the version is 3.5.5.
