As explained in the reference manual RM0503 rev2, §14.10, the MCU has an internal bandgap voltage reference, which can be measured by the ADC peripheral. This reading can be compared to the one performed by ST in the factory (and stored in flash), so...
Hi everyone, I am trying to use LPTIM1 and I2C3 to read the values of a sensor's register every 1 second and save them into a data buffer while in Stop2 mode. What I would like to know is if it is possible to store data sampled at a given frequency ...
Good dayI have created a board that contains a SD card, which works great with L4, F4 and F7 microcontrollers. This board allows me to swap out a F7 uController for a H7 uController since pinout is the same.However, no matter what I do, I cannot get ...
I am trying to use the usb audio to obtain computer sound data and i have blue pill and STM32F746G-DISCO on my handFor blue pill,i add some prints in this functionstatic uint8_t USBD_AUDIO_DataOut(USBD_HandleTypeDef *pdev, uint8_t epnum);but it only ...
Some parts of the computer can not read the STM32 bootloader in the device manager after connecting to the computer via USB, and the Unknown device will be displayed, but if you change some computers, you can read it correctly, and ask what this driv...
Hello community, I'm struggling to get the dual bank feature to work with the STM32F765 as in the X-CUBE-DBANK-F7 example shown. Following situation:I have two similar FWs, only a different LED is toggled. In the OB I set the nDBank to 0 and defined ...
Hi,I am trying to make the jump work with an F103RC, and have read many posts in this community, but the jump simply does not work for me. The jump code is mainly from DavidNaviaux in the following post:https://community.st.com/t5/stm32-mcus-products...
I have the following problem with my STM32H743:I want to use the ADC3 for an injected conversion, but the ADC3 interrupt does not call the ADC3_IRQHandler, instead the SysTick_Handler is called whenever an ADC3 interrupt happens. When I read the ISP...
Hello!I'm facing an odd problem with STM32H750VB MCU and the USB Host routine on a custom board. I'm working with the latest HAL (v1.11.2) at 400 MHz and USB using the 48 MHz internal RC, "host only" mode + FatFs "read-only". The software is quite si...
Hi,We try to send an receive data to the external APS6404 RAM.Therefore we read the application note AN5050 and copy the function from page 55 (7.2.5).At first the function HAL_RCCEx_OCTOSPIDelayConfig() we cannot find in the library.What is correct ...
