This was a tricky bug to find. I am doing context switching. Everything seems to working well until a context switch happens while one of my tasks has called a different function. Specifically, HAL_GetTick(). To be clear the switch is happening while...
I am looking at the STM32U073x8/B/C Datasheet - DS14548 - Rev 2 - March 2024. Table 12 on page 35 is a list of all the pins and which pin they are connected to on each package. The row for VDDUSB does not have a pin listed for the UFQFPN32 packag...
Hello,I have been utilizing the OTG_HS peripheral on an STM32U5A5 to act as a USB host. I am using the USBx stack in a non-secure application and initializing the peripheral as follows: VOID USBX_APP_Host_Init(VOID) { MX_USB_HCD_Init(); ux_host...
Hi all,I am working on a motor control project using STM32, and I am trying to calculate the RPM of a BLDC motor using Hall sensor pulses. I have set up a SysTick timer to trigger an interrupt every 1 millisecond, which should increment a counter (sy...
Hi guys, I m having an issue with my Nucleo F401RE. I m porting a code based on the use of SPI2 that worked very well on Nucleo G431RB. I made same setting on Nucleo IDE (see picture). After inizialization of periperhals NSS (Chip Select) goes to hig...
Hello ALL,ADC values when 2 channel are disturbed when used in STM32L071 board. i have tried changing the sampling time of channels still no difference the voltage at that pin is around 2.5 volt but the ADC value after conversion i am receiving is ar...
Hello,Hello,I am seeking either a ready-to-use or partially implemented driver for the HM01B0 - QVGA SPI Camera Module to use with the NUCLEO-F767ZI board.My aim is to recreate a project I previously completed with the Portenta H7 on the OpenMV IDE,...
Hello,I have a strange issue with backup ram in F405. It is battery powered after main power off.When i remove battery and power up board, whole bkpram contains values of 0 - this is normal. But after initialize procedure whole memory contains random...
Question comes from PM0056 Programming Manual STM32F10xxx/20xxx/21xxx/L1xxxxCortex®-M3 Programming Manual Page 129I calculated the last address is 0x350Is it a problem with the manual?
Hi I am working on a own prototype.The issue facing is NRST pin pulled low once powered on.Actually it should give me 2V.MCU used is STM32G030K8.and also on checking the PCB tracking its fine .When we checked by removing the MCU chip NRST is 2.0v .Wh...
