Hello all, I have designed a board for sensing purposes and I am using the following ST components: STM32U575ZIT6Q. I am supplying this component with 3V3, which I get form a 5V/3V3 LDO. Between the output of the LDO and the supplying rail to the STM...

Hello all, I want to use a NucleoU575 board to test an accelerometer sensor.I have written the driver for this accelerometer and currently, without having it connected to the Nucleo, I am trying to check whether my SPI3 Clock is working.This is the c...

An update: I have desoldered the pins and have connected them based on the recommendations above. The VDD pins are now reading 1.1V and the issue described above is solved. However I am now unable to comunicate with the STM chip. Could the mistake de...

Hello Tom, Thank you for your reply. I do understand your argument and I tried to make the necessary changes in my code. So the way I exctract my tempRaw now looks likes this: tempRaw = (uint16_t)(regData[0]<<0 | regData[1]<<8); However I am still ge...

Hello Federica, Thank you for the reply.What I'm also trying to understand is the values of the registers. For some of them, the default value is given in binary form on the datasheet. For others, the value is just "output". How should I understand t...

Unstable voltage supply to STM32U

Using accelerometer IIS3DWB

SPI3 Clock not working on NucleoU575

Are there any resources available that can help me develop a driver for the IIS3DWB accelerometer sensor based on SPI communication and STM32 MCU?
