Hi, We are in a new project (first time with embedded Linux and device tree's in general) and i want to config my device (STM32MP151CAA3 on a custom board) to boot from FMC NAND flash (MT29F8G08ABACAH4-IT:) and i am having some trouble with the devic...

Hi,I am using a STM32MP151AAA3 and i need to control an RGB LED via PWM control (something like the WS2812B). I was looking into the PWM driver options for Linux side control and can't find options for PWM control for specific buffer sizes or anythin...

HI, We have designed a test fixture for a 6 panel PCB in which we use 6 individual STM programmers (STLINK-V3MINIE) and we sometimes see a problem where windows no longer recognizes one of the programmers and we can't get it back (complete system re...

Hi, I am currently actively debugging and working with the sensor and it shows correct measurement data when i set the profile to 'Long range' example (settings from the 'um2039' User manual). however the sensor response for RangeDMaxMilliMeter:...

Hi,We are currently in a project where we want to use the VL53L0X chip for ranging. And the example code with PC application seems to work quite good. the next step is to create a PoC using our own system (where we are now).I am currently reading up ...

Hi Olivier,Thank you for your reply.After some internet searches i read on a few places that buffer PWM writes are a real hassle or just won't work under Linux. Our solution also due to time constraints was to replace the WS2812B LED's with 'normal' ...

Hi Seb,An update, my problems where related to hardware and noise while calibrating. after making some changes to the calibration sequence and room variables (block out external light etc.) the sensor is now measuring beyond the 1,2m and shows accura...

HI John,Thank you for your reply, i was under the impression that DMAX was the max amount of distance the sensor could detect with the given settings. (e.g. for long range profile this would then be higher).Then ill change the softwares implementatio...

Hi,After throwing away the RangeDMaxMillimeter variable problem i am now left with the reason why my sensor does not measure beyond 1,2m. as soon as the measurement goes beyond 1,2m i get the following resulting measurement data:Can anybody help me m...
