Hi,I'm configuring the independent watchdog in the STM32F103xx medium-density using the registers.During the IWDG the PVU bit is not cleared by the hardware. The reference manual (page 498) says the following:"PVU: Watchdog prescaler value updateThi...
I am unable to start a PWM signal on my Nucleo board --> I was not able to observe a signal on an oscilloscope.Please see the following code and Cube configurations.1) Is the following code all that is necessary to start a PWM on a channel (given it ...
I have experienced this issue on STM32L4R and STM32U5. If debugging through STOP mode (with DBGMCU_CR_DBG_STOP set), the flash memory occasionally seems to read out garbage as the MCU is coming out of STOP mode. This typically causes the CPU to har...
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
When I'm enabling DMA and run the code, the debugger hangs at "SCB_EnableDCache();" even though the function is correctly excuting when I go step by step. Also as seen in the examples the problem gets solved when using a static declaration "static v...
Is it possible to DMA DCMI data to external SPI PSRAM (8MB)? I don't have enough pins to place SDRAM and wish to buffer Camera data.
Hello,I wrote a Boot program in flash to initialize sdram and copy the app program to run in sdram. The current state is able to jump and run normally, but the length of jump time seems to be positively correlated with the size of global variables in...
Hello, Just a quick question as I need confirmation :Using a STM32H7 ADC in a differential input mode, does this circuit work ? The output of the op-amp is Vout = G * (Vin[+] - Vin[-]) + 1.65 .Then the ADC output should be between :[0 - INT16_MAX] w...
I have a project running on my Stm32H7. I imported my ethernetif/lwip settings from the Stm32CubeH7 H723 lwip + freertos http server example, but made some small changes. For the most part in the most basic sense, the driver works and my board at lea...
Hello,Using the STM32CUBEPROGRAMMER v2.2.0 + the NUCLEO-N657X0-Q :I tried to set the OTP_124 -> HSLV_VDDIO3 bit to 1 but it did not suceed. First, I read the whole otp, put 1 in that field then press Write and it did not work, the OTP_124 stays at de...
