STM32F042: External clock and clock output
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 ...
Issue with PA2 and PA12 pin in L432KC Nucleo
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 ...
Master/Slave problem on TIM3 in STM32L476 - slave not counting when ITR2 selected
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...

How to use PA15 on STM32F302RD?
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...
External (Timer) trigger for regular ADC channel
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...
problem with dfuse
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...
Resolved! What is the reset value of GPIOx_MODER?
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...
STM32 - ATA read/write
Well, i need to read data from the hardware that uses ATA interface, my mcu is stm32f407, all is came in my mind is to make software implementaion by bitbang the pins, but ATA has 16 bits data interface, therefore ill need to bitbang each pin connect...
