Hi, I am trying to set SysClock to 216MHz using stm32f769xx.hI have no access to MCO pins, so for testing I am trying to blink a led every second. ARR and PSC values to achieve it will confirm if I am to desired SysClock frecuency (Blink led using ti...

Hi,I am facing some issues related with VL6180x offset calibration (I am not using cover glass, and I have tested many sensors on breakout boards from Adafruit and Pololu).First, with default SYSRANGE__PART_TO_PART_RANGE_OFFSET value, range measureme...

Hi everyone,I have an VL6180X connected to a PIC18F46J50. VL6180X is powered to 3V3 and I have implemented I2C routines and application code as in https://cdn.sparkfun.com/datasheets/Sensors/Proximity/VL6180_ApplicationNote.pdf to work in single shot...

Hi, I am new on STM32 and I started a product prototype using STM32F769-Discovery. I developed all software using default clock configuration, which uses HSE. Now I want to change to HSI, but USART is not working ( Not true, only works when board res...

Hi @John E KVAM , thanks a lot for the information.However, it keeps answering with wrong distances (with vl6180_simple_ranging.c and using I2C1 interface). I am using a STM32F769-Discovery board. As you said, I have used ST32Cube for adjusting I2C ...

Hi @John E KVAM I have been testing the same vl6180x breakout board with a Raspberry Pi and adafruit_vl6180x.py software and with it that's working (distance measurements are right).However, I am adapted the adafruit library for using in the STM32 a...

Hi @John E KVAM I have tried crosstalk calibration and keeps not working.We are not embedding the sensor in any structure, as we are using the breakout boards of Adafruit and Pololu, where sensor is on the top.However, we have realised that we get "...

I have moved it to https://community.st.com/s/question/0D53W00000KolaQSAR/vl6180x-offset-issuesI am not using cover glass, so I don't think crosstalk may be the problem. Anyway, I will try to adjust cross-talkFor testing we are using white sheet of p...
