Hi.I am using STM32H7B3LIHQ MCU, MX25LM51245GXDI00 OSPI flash, IS42S32800J-6BLI SDRAM and 24bit TFT screen. I used the schematic of the STM32H7B3I-EVAL (MB1331) board when creating the scheme. I wrote programs for FMC, OctoSPI and LTDC peripherals us...
I am experiencing processor freezes at certain points of use in our products using STM32F4.I am analyzing the cause and have a question regarding this.The processor I am using is STM32F469NI. There is a specific operation that it freezes at, and when...
I'm using Vbat as a battery voltage monitor on an STM32L431. Vref is the VDDA pin on this part, which is 3.3V. In my test case, Vbat is also connected to the same 3.3V.Vbat reads a raw count of around 1044. The internal divider is /3, so this come...
Hi i encounter this error while compiling SPI1 at ST7735.h, i dont understand as this error 'SPI_HandleTypeDef' type was generated by .ioc in main.c already and i had call this statement in ST7735.h. Could anyone kindly help? error: unknown type name...
I am using a STM32U031 part with register level configuration (no Cube libraries). The Timer should be straight forward to start in a single-shot mode but when I set the LPTIM_CR_SNGSTRT flag in the CR register, the CNT register never increments and ...
Both 'U5 ADCs contain the LFTRIG bit; however, I could not find in either 'U5 datasheet the Tidle value above which this bit has to be switched on.JW
Hi all, I'm trying to receive UART data from an xbee module, I've noticed the xbee is sending out the data correctly (using a logic analyzer) however the STM32L431KCU6 is not receiving this data properly and instead seems like the data is being buffe...
HelloI am starting a project with a STM32U585CIU6 and an OV7670 camera module. I want to use the DCMI interface to get the data, and I'm using the Introduction to DCMI to STM32 MCUs document as a reference.STM32U585 datasheet mentions the support to ...
Hi, I have an inverter project designed with stm32g474xx and there is a "h-bridge" topology in the system.Can I create a uni-polar PWM to get three-level output while controlling this topology with hrtim1? Can hrtim1 generate two complementary PWM ou...
Hi, I need to trigger DAC1 and DAC2 from HRTIM Timer A on a STM32G474. I have set the DAC Sync option inside the HRTIM Timer A settting to generate a DACTrigOut1 event that triggers my DAC1. But DAC has a separate Trigger event that also works for DA...
