Hi there,I want to do a printf redirected to a Tera Term using the USART2 on the STM32F407G-Disc1, but it doesn't print while the same code works on the NUCLEO-F401RE. I found this instruction in the user manual UM1472. Does it mean that I have to u...

The general API user guide, UM2356 (rev 2), says that the min timing budget is 20ms, but the ultra-lite driver guide, UM2510 (rev2), says 15ms is the minimum. I've tested with 15ms (I'm using the ULD) and it seems to work fine, but just wanted to ma...

VL53L1X overshoot?In my initial testing with the VL53L1X, I'm seeing that by rotating the sensor from directly facing an object to facing the ceiling, which is well over the max distance away (I'm operating in 'short' mode, so that should be 1.3m), I...

Dear members,I am currently trying to interface Arduino Atmega 328p with VL6180X via I2C Bus. I have prepared basic code for reading Range value in single shot and continuous mode, it is working file. Now I changed I2C SCL to 100 KHz, 50 KHz, 20 KHz ...

Hi Markus,3mm is a bit challenging but it should work if you can keep the air gap (distance between the cover and the ToF) as small as possible.What is the dimension and the material of the object to detect at 1m? Please check out the VL53L8CX ToF fo...

Thanks for the update. Simple I2C read write function checks at the first step are helpful ;)

HiYou have 3 solutions:You port the VL53L5CX bare C driverYou use the Arduino IDE with the VL53L5CX Arduino Library https://github.com/stm32duino/VL53L5CXForgot the ESP32, use STM32 ecosystem, Nucleo F401RE board, to access to full example codes avai...

STM32F407G-DISC1 printf issue

There seems to be some conflicting information in the VL53L1X API documentation regarding min timing values for 'Timing Budget' and 'Inter Measurement Period'.
