I just purchased the STM3221G-EVAL board and I am working through some examples. I am currently using running the HMAC example and it runs fine. However I am unable to get the HMAC to match the test vectors provided in the specification (https://tool...
The LPTIM1 interrupt is running. But if I use the EnterStopMode function, the controller is not gone at the stop mode (LED1 come directly). If I use the EnterStopMode function the second time, the controller goes into the STOP mode and after few sec...
I'm trying to connect the limit switch to my stm32f429 discovery board. the digital read function is not working. I didn't get the desired output instead all the signals are high in IDR. I don't know what I'm missing?. I watch some examples on the we...
Hi all,after reading the AN2606 concerning bootloader seems to me that every device came with a preprogrammed bootloader I've correctly understand?For the STM32F105RBT6 inside the EVAL6480H-DISC board, the bootloader should be the USB type (so by mea...
1. Do I need to provide power from different regulator for VDDIO2 pins or if I use the same level (3.3V) can I use VDD? I simply need lots of GPIO pins.2. LL_PWR_EnableVddIO2 has no effect in my case. IsEnabledVddIO2 always returns 0. I did wait for ...
I use STM32F091RB MCU.If I want to make MCU shutdown, how to enter shutdown mode?Is there any HAL API or something else?Thanks
As described before (https://community.st.com/s/question/0D50X00009sWdDqSAK/stm32f042-bootloader-activation) I want to use 2 STM32F042 as CAN controller. So far I planned to use the internal HSI RC oscillator, but a +-5% tolerance seems critical for ...
I'm using a reflective sensor to measure speed. In my PCB, I wrongly connected PA12 to the output of the sensor. I actually needed PA2 to use it as TIM2_CH3. So I jumped PA12 and PA2. This pin is pulled up to 3.3V with a 10K resistor. With no sensor ...
Hello,I am working on the NUCLEO-L476RG board. I am trying to use two pairs of counters in master/ slave mode. In the first chain TIM2 is the master and TIM4 is the slave so in SMCR of TIM4 ITR1 is selected and this works as expected. In the second c...
