STWINKT 1B bug in fft analys demo.

In ultrasoun library has a bug. If change you in fft_app.h FFT_OUTPUT program is not compiled. Please change code like this  static void FFT_Thread(void const *argument) { (void) argument; #if (configUSE_APPLICATION_TASK_TAG == 1 && defined(TASK_F...

Getting correct register value when reading "WHO_AM_I" register on LPS25HB mems sensor but the wrong values read from the sensor. (STM32G474RE)

I have a board developed by one of my colleague, that uses a STM32G474RE microcontroller and in his SPI1 I had both an LPS25HB (Mems ST barometer) and too an acelerometer SCA3300. For the LPS25HB I'm using the following driver:


Resolved! FSM_ODR register settings on LIS2DUXS12

I am suspecting that the ODR setting in my application is not correct. I want to be using 25Hz so according to the datasheet I would set register address 39h to 48h. 25Hz equals 001 which would give 01001000 = 48h.But all examples and also the Unico ...

Resolved! STEVAL-MKI168V1 with IIS2DH I2C issues

HiI currently try to integrate the STEVAL-MKI168V1 for a development board via I2C.I use a TI MCU and use the default drivers provided by ST. The sensor does not respond to the defined I2C addresses of 0x31 resp. 0x33 if SA0=1. After doing a I2C scan...
