UART_FLAG_TXE is not set while a lots of ADC interrupt are issued.
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...
How to Trigger ADC1 with TIM1_CH4?
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 ...
Resolved! How to move DMA ISR functions from flash to RAM? (hoping they run faster)
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...
What is the default operation of OSC_IN & OSC_OUT for the 32L0x2?
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...
How to retain some data in flash memory during appplication running on STM32F405 ?
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 ...
Resolved! STM32F429 TIM1 trigger flag (TIF) issue
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...
how iadd .o file link in ld file ？
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?
How to use DMA control GPIO in STM32H750 series?
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...
