I am trying to read a square wave, or rather I am trying to detect when a square wave is falling using the Nucleo-F746ZG board. Using CMSIS v2, using STMCubeIDE 10.1The square wave comes from a flow sensor, and every time it goes from high to low an ...
Here's what I have:https://tinyurl.com/2y2b76gjThe opto-coupler simulates (very roughly) the TCST2103 optical sensor.My goal is to accurately measure the pulse frequency. The Q MOSFET's gate represents the MCU GPIO input. The 1M resistor represents t...
I bought X-NUCLEO-IKS01A3 and I have already an STM32 Nucleo-144 F767ZI board. Now I wanted to connect both so for that I went through the F767ZI user manual which i found the following table then I went through the X-NUCLEO-IKS01A3 document there I ...
I am seeing some strange happenings using X-CUBE-MEMS software pack, which generates some code for user buttons, LED outputs, etc.I noticed the user button was always returning GPIO_PIN_SET even when it should be returning GPIO_PIN_RESETI make a call...
Hello. I have VL53L1X working in window mode with GPIO polarity active low:Window mode = 3 (within the distance range (min/max)).Min = 50mmMax = 200 mm It is working well. If my hand is: Within window: GPIO interrupt goes up and downBelow or beyond w...
Posted on May 07, 2018 at 17:27I'm developing an applications where an array of VL53L1X sensors would be used. During that development effort it became apparent that there were some timing issues while cycling through the sensors and when I expected...
Posted on March 09, 2018 at 00:18Hey! I am using the accelerometer LSM303AGR to read some acceleration values on external interrupt. If the threshold is overcome, and interrupt will be triggered and in the ISR, I am reading the FIFO of the accelerom...
Posted on March 18, 2017 at 11:51Hi all,I am attempting to build a microphone array out of digital MEMS microphones and I am trying to determine if I can achieve a reasonable system on an STM32F7 microcontroller. Ideally I would like to capture the ...
