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...

Hey,I can't access PA15 with the STM32F302RD µC. It's obv used for JTDI but it's possible to change this mode (if I can trust the reference manuel). With the "flexible SWJ-DP pin assignment" I have to change the mode to "JTAG-DP Disabled and SW-DP En...
Hi everyone!So as the title suggest I would like to get some help for my STM32F303 Microcontroller.In the application Timer1 is used to turn an external pin ON and OFF at a constant frequency, while ADC4 is used to read some feedback with the same fr...
Posted on August 12, 2011 at 10:20Hi, I am currently developing a PC application for STM32 using Inemo board.The PC application will be able to upgrade the firmware of the STM32 using Dfu mode. Iam using Visual studio Vb.net for the PC side appli...
According to RM0433 rev 5 section 10.4.1, the reset values are 0xABFFFFFF for port A, 0xFFFFFEBF for port B, and 0xFFFFFFFF for all the others. This appears to agree with the bits shown in the register table at the end of the chapter. However, in the...
