Resolved! Anyone know of a Nucleo pin-out print utility?

I'm creating code for an STM32L073 that will connect to another system. The final boards are not done yet (and will not be for a while) so we have a Nucleo board that we will be wired into the demo board for the system. I made a spreadsheet with the ...

Duty cycle on Timers

I was reading in "Mastering STM32" and in the intro of PWM pulses (pg355 hard copy) said that "The square waves generated until now have all one common characteristic: they have a Ton period equal to the Toff one. For this reason they are also said t...

hello, im using stm32f446re nucleo board for practice and i have configure the board for SPI communication. i did the program for the 8bit and 16bit DFF. Now i using HMC767 PLL as a salve device whos register size is different from that of nucleo board.

i dont know how to send variable size data evrytime. The HMC Mode protocol for the serial port is designed for a 4 wire interface with a fixed protocol featuringa. 1 Read/Write bitb. 6 Address bitsc. 24 data bitsplease need yout help on how to send >...

What's the source address when using DMA PER_2_MEM Mode?

Hi Folks,i'm working with the STM32H750 controller. At the moment i'm trying to get the ADC working with the DMA in a Peripheral to Memory Mode. Since i've no idea how to do this, i've started to checking the HAL functions and found the HAL_DMA_Start...

LPTIM as a pulse counter

Hi, bom dia.I need to use LPTIM as a pulse counter in stm32L431. I created a project using stm32cubeIDE and start only the necessary to test the LPTIM, but when i call HAL_LPTIM_Counter_Start() or HAL_LPTIM_Counter_Start_IT() never return HAL_OK. I h...

STM32L051 Stop Mode and LPTIM interrupt

I use HAL to go to STOP mode with interrupt (WFI), but the microcontroller immediately exits stop mode.I have LPTIM setup with HAL_LPTIM_Counter_Start_IT() to give interrupt after a few seconds, but even without setting up LPTIM I can't get the micro...

STM32F429: Can Flash Sector "write protection" be set and temporarily cleared during operation (to erase or write some data)?

Hi AllI have been experimenting with the Flash write protection most of the day and was hoping to be able to set it by just writing the setting in the FLASH_OPTCR register, however the value that is written doesn't seem to affect anything unless comm...

Timers, How to set the timer ? In STM32 Please explain me. Watch my video I am explaining Timer multi tasking concept https://www.youtube.com/watch?v=EYXbNmaPBWo My Timer explanation in PIC 8 bit https://www.youtube.com/watch?v=dP1S4p7a1js

In Stm32 has too many parameters, So please some explain me how to use this ?. please watch my timer videos. because I know how to use the timer in PIC, but in stm32 which is prescalar and how to calculate for generating pulse(in expected frequency)
