Hi,

First of all , thanks a lot for your work !
I am testing your dev resolution.ino (update last night) for a resolution 8x8 on a Teensy4.0 and it doesn't work. Nothing in the serial and the function vl53l5cx_check_data_ready(&_dev, &is_ready) in the sensor.isReady() line block.

I have last version of all framework and library and i use PlatformIO (but i don't think it is the problem).
When i test, *p_ready is never to 1, it keep 0, so function vl53l5cx_check_data_ready engage an infinite loop because the following condition in never true :
if((p_dev->temp_buffer[0] != p_dev->streamcount)
&& (p_dev->temp_buffer[0] != (uint8_t)255)
&& (p_dev->temp_buffer[1] == (uint8_t)0x5)
&& ((p_dev->temp_buffer[2] & (uint8_t)0x5) == (uint8_t)0x5)
&& ((p_dev->temp_buffer[3] & (uint8_t)0x10) ==(uint8_t)0x10)
)

More precisely those conditions is never true :
p_dev->temp_buffer[0] != p_dev->streamcount
p_dev->temp_buffer[0] != (uint8_t)255
p_dev->temp_buffer[3] & (uint8_t)0x10) == (uint8_t)0x10

Is there a buffer trouble ?

On Ubuntu 20.04, Arduino 1.8.13, with the library installed via downloading the zip file and importing it from
Sketch -> Include Library -> Import ZIP library...

The test code is basically just the initialization from the autonomous ranging example.

Hi,

thank you very much for publishing your library for this sensor.

unfortunately on my STM32 (Nucleo F446RE) this code get stuck up during the initialization, as the sensor does not return the expected value in poll_for_answer, here is a permalink to the corresponding line in code: https://github.com/simondlevy/VL53L5/blob/fa743d1c319c5fd53562447cf11af5ac3199ccfd/src/vl53l5cx_api.cpp#L445

The issue is described here on the ST Community forum too:
https://community.st.com/s/question/0D53W000010uFcTSAU/vl53l5cx-driver-vl53l5cxinit-fails
The error is attributed to too small RX and TX Buffers. I can see that you have a Fix for some STM32 boards implemented, and have defined ARDUINO_ARCH_STM32, but this does not change the behavior. Are you aware of other issues with STM32 boards?

I am using PlatformIO with the stm32duino, did you use the STM32 for your Ladybug tests too, or did you use Arduino_STM32?

(Same message repeated over a hundred times...)

That line number is the end of an attempt to initialize a very large array with the VL53L5 firmware (according to the comments, anyway). Explicitly setting the size of the array gets rid of the "Sorry, unimplemented" message, but not the "too many initializers" message.
