Hello,I'm using an ST32U5 microcontroller and I'd like to ask some question about the ADC linear and offset calibration feature.1 - This feature is only available on ADC1 or is it also available on ADC4?2 - Right now at startup I'm launching the ADC1...
Hi all, i have two nucleo-f103rb boards, i am trying to use one board as i2c master and second one is as i2c slave.the boards communicates well if slave is reset first and master is reset after slave reset i.e.master is reset when slave is running.le...
Hello , wanted to interface QSPI dual flash with STM32H743Zit6 . The External Flash memory i am using is sst26vf064b . I am having 2 of this Flash memory on my hardware Can anyone help me with the same?I am trying to read the ID dataFirst -- With SP...
I have tried Timer 2 CH1, and Timer 3 CH1. No Luck.I know the pin has a square wave going into it and the timer is counting, because I can poll GPIOB->IDR and read TIM3->CNT.Nothing I can do can get a reading other then zero from TIM3->CC1I cannot g...
Hello together,I'm using Nucleo-32 board (with a STM32G431KBTx) and have got some problems...In my project I'm using:-> UART (here I'm using RX-DMA and interrupt with an IDLE-flag)-> ADC, one channel-> I²C with an EEPROM (no DMA, no Interrupt)Problem...
Hi all,I have a project running on an STM32F427VI that makes some specific use of the dual-bank flash, both for storing certain configuration parameters and for a custom bootloader. It's great, but I don't get anywhere near using the full 2MB of flas...
I'm trying to run a 4-stage dc-dc converter using the NUCLEO-G474 board.For this, the MCU needs to execute 4 parallel controllers at 200 KHz. I am aware of how to set up a single filter/controller by looking at AN5305 application note, but is there s...
I want to reduce the output voltage of the GPIO pin by programming. So, I'm finding a way to reduce core voltage.Is it possible? then where can I do it?If not, is the only way to change fixed LDO physically?For example, using 2.0 V-output LDO.
I am trying to port over some code from PIC to STM32. In the pic code, the ISR took the pointer data from the received uart message (1 byte) and then sent that pointer data to a circular_buffer_put function (effectively putting it into the circular b...
