Resolved! STM32F427VI firmware retrieval
Hi All, Been reading and learning a lot about MCU's in general. I'm very very new to all of this so please bare with me.The board comes with STM32F427, and a custom .exe that can flash directly via USB-C. I've read about fake STM32's, and. I'm not su...
Resolved! Problem with creating external loader on STM32F411 and W25Q64
Hello I wanted to create a external loader for STM32F411CEU6 (WeAct Blackpill board) and W25Q64 flash memory chip. I did it based on the tutorial from youtube link: https://www.youtube.com/watch?v=KlG2doCkREM&t=1792s I the tutorial i found link to W2...
Flushing/resetting DMA state
So DMA can read/write from 16bit SPI DR, to 32bit memory variable, in circular mode,I need to reinit stream, but DMA TX ends up off by one 16bit in destination array,so how can I partially reinit DMA to beginning or array/or even addresses?Without fu...
stm32f4 timer based interrupt function execution
hey!im working on data logging and want to store all data in text filewhere i want to save date and time with the use of RTC clock and external interrupt based on timer with gap of 1 sec i have things configured correctly for the RTC which works fine...
Resolved! Issue with uart USART_ISR_EOBF bit
Hi I have a stm32L433, and setup Uart1 for standard TX and RX with interrupt for both send and receive (9600N81 setup). I don't use any hardware handshake . Within the IRQ routine occasionally the USART_ISR_EOBF bit in the ISR is set , and I am not u...
Resolved! STM32U5xx: CPUID and REVID - where to find documentation of the expected values?
I read and display the CPUID and REVID on my project.I see the difference between using an U575 chip vs. U5A5 chip (NUCLEO boards): U5A5: CPUID: 0x410FD214 REVID: 0x30016481 U575: CPUID: 0x410FD214 REVID: 0x20016482 OK, based on ARM Cortex-M33 docume...
Resolved! HRTIM activates output immediately when re-enabled rather than on compare match
I am using HRTIM in my project such that the output TA1 of timer A generates a delayed pulse after the timer is triggered via the EEV1 input. I have two compare values defined in Advanced configuration mode: One to set the output high and the other t...
HAL fails to switch VRef from internal to external H743
Changing VRef source would seem simple, but it doesn't work, there is no change in the levels the ADC records. __HAL_RCC_VREF_CLK_ENABLE();HAL_SYSCFG_DisableVREFBUF(); // Disable the Internal Voltage Reference buffer, uses external 3.3vHAL_SYSCFG_VRE...
Resolved! ADC Measurement error in STM32F030C8
Hi ST Community, I am trying to measure system voltage (Lead Acid Battery) using ADC input of STM32F030C8 (PB1). The system voltage can be between 9V and 13.5V () so I am using voltage divider (10k and 1k) to lower the voltage to the 0 - 3.3V range. ...
