Digital Image Processing with STM32 ?
Dear Members or ST Employee,I've been looking for inspiration from STM32 board for digital image/signal processing,Any boards that can be used for image processing straight away from development board?because I need RAM for it, and the internal RAM w...
STM32L4 VRefint dependency on temperature
VRefint is between 1.18 and 1.22V depending on temperature. As in our hardware we have termometer available i would like to know more precisely what Vrefint voltage actually is.What are exactly the relation between temperature and Vrefint voltage?equ...
Implementation of filesystem
Hi i am trying to implement Littlefs filesystem on STM32L151 MCU which is interfaced with external Flash memory using SPI.is it already implemented on any one of the STM32 board? if yes-i need to know what are the key features to be carried out to im...
AHB and APB
Hi ST Community,I’d like to know why sometimes we use GPIO with AHB and sometimes with APB ?
Is this a documentation error? (PM0214: Cortex-M4 programming manual, NVIC base and offsets)
In section 4.3.11 NVIC register map (p.217) the base address of the main NVIC register block is stated to be 0xE000E100. The Offset to NVIC_ISER0 is then given as 0x100. This would make the address 0xE000E200.On p. 208, however, the address of NVIC_I...

Dear Members, I want to send SMS but I stack with ^z,how can I rectify it ?uint8_t aTxBuffer5[] ="AT+CREG?\r"; uint8_t aTxBuffer6[] ="AT+CGMF=1\r"; uint8_t aTxBuffer7[] ="AT+CMGS=\"61400000997\"\r"; uint8_t aTxBuffer8[] ="\"TEST SMS FROM STM32 ...
Resolved! stm32H743Y vs stm32H743V
Dear all,I am facing to a stm32h743 issue. I have a Nucleo with the stm32H743 Rev Y that work perfectly. Now, I just tried the new Nucleo equipped with the stm32H743 Rev V. As expected, my previous code (Rev Y) does not work on the new device (Rev V)...
I2C errors and interrupts
Hi there, I'm using the STM32H7 to talk to a CS2000 clock chip over I2C. I'm using interrupt mode.I'm just trying to read the chip's ID register for starters. Despite the CS2000 ACKing the first 'setup write' byte, it won't write the second byte (wit...
Hi everyone, I am fairly new to ST and I'm working on a project where i need 8 phase shifted pwm signals(each phase shifted by 45 degrees and same duty cycle)
i was thinking if there is a way i could generate 4 timers phase shifted by 90 degrees wrt each other so that i could use them to generate 2 pwm signals (on each timer using asymmetric mode) . can this be done? if not, is there any other way i could ...
