I've come across the following code in system_stm32h7xx.c, present in all example projects in STM32CubeH7 FMC_Bank5_6_R->SDCMR = 0x00000009; tmpreg = FMC_Bank5_6_R->SDSR & 0x00000020; while((tmpreg != 0) && (timeout-- > 0)) { tmpreg = FM...
Hi,I am using 4 ADC channel to read MIC circuit with STM32G030C8T6I am using ADC interrupt service to read ADCsI set ADC as follow:Clock Prescaler: Async clock mode divided by 32 Scan conversion Mode: enableContinuous conversion mode: enableADC_regul...
On the STM32F401RE, I'm trying to get a compare match on CC4 on TIM1 to trigger an ADC conversion in injected mode, but the ADC is never seeing the trigger.How do I set TIM1 to generate the TIM1_CH4 trigger on a compare match on CC4?TIM1->CR2 has an ...
Im using a stm32f105RBT6 and i am in need a ton of softpwm pins.My solution (with the help of @Community member ) was to run 4 DMA channels triggered by 4 different timers addressing 4 different GPIO ports (in a circular mode).This worked like a cha...
Here's my issue: in converting an STM32L072 QFN32 to BGA49 I routed the NRST line across the PH0 & PH1 balls to avoid using via-in-pads. However, it appears that in a virgin part HSE is enabled by default and OSC_OUT is pulling the NRST line low, whi...
Hi everyone, For some reasons, i need to store 3 uint16 in flash (once) when my application is running. Of course the goal is that those values will remain after a power down / reset. Does someone knows how to do this properly ?Do i need to define a ...
I have TIM1 configured in one pulse mode triggered by rising edge on TIM1_CH1 to generate single pulse. Timer works correctly (generate single pulse for each rising edge on input). Datasheet claims that TIF flag is set on trigger event in all modes b...
i'm using stm32H7,i want to use ITCM/DTCM ram,so i want add .o file in stm32H7XXXXX.ld filei try .main_section { . = ALIGN(4); CORE/src/main.o(.data); . =ALIGN(4)}>ITCMRAMbut gcc report errorso i want to known how fix it?
OK, I am using STM32H750BV, I have a driver that needs very critical timing control, so I want to use DMA trigger by timer, transfer memory data to GPIO BSRR register, let GPIO can according to time pass to generate the signal, but most of all refe...
