I'm trying to generate a cascade of DMAs:1) HRTIM trigger ADC. 2) On ADC conversion completion, DMA ADC results to memory.3) On ADC DMA transfer complete, DMA memory to different peripheral.When a DMA occurs, the DMA request multiplexer generates bot...
I am unable to communicate with the MCU via UART (115200 bit/s). It looks like the program inside MCU is not running. I think the problem can be probably in not running LSE 32.768kHz crystal oscillator.Is it possible to enable LSE clock on PA8 if I h...
Hi there,I am trying to do some digital signal processing on a STM32G031F6 by interfacing an SPH0645 MEMS microphone via I²S. I'm running into strange issues however, that I haven't been able to solve in the last few days. I am switching to an analog...
Hello.Very frequently I end up chasing problems that not suppose to be in first place.Here is example ( making 32b counter of 16b by counting overflows)volatile void Delay_ms(uint32_t ms) // delay in ms { time = 0; time_start = LPTIM2->CNT; o...
Hi all,is it possible to use the same GPIO-pin as Timer external trigger and falling edge external interrupt.I'd like to create an application in which a rising edge on a GPIO starts a timer that sets an output for, say 2ms. After this time, another ...
Hello.I'm trying to use SPI interface in STM32F051r8t6 micro on my STM32F0 discovery board. I got it to send data, but I set data lenght to 8bit, it is sending double that (first 8 is my data, but second 8 bit is always 0x00). When I set it to 4-bit,...
STM32F100RBT6 TIM15_CH1 and TIM15_CH1N complementary pwm mode does not generate the complementary outputI have a problem with my complementary output generation at Timer 15 Channel 1. I have set all parameters at CubeMX and have set HAL_TIM_PWM_Start...
Hi, I am trying to set SysClock to 216MHz using stm32f769xx.hI have no access to MCO pins, so for testing I am trying to blink a led every second. ARR and PSC values to achieve it will confirm if I am to desired SysClock frecuency (Blink led using ti...
Hello,I am using STM32 CubeProgrammer Api and I succesfully bootload my STM32H743ZI but it stays in bootloader mode after download, is there any way to ask a reset ?There is a reset function in the dll but it specify that it only works in SWD/JTAG mo...
Hi,I'm using the STM32G474 in dual BLDC driver application.I'm operation the encoder interface at X4 mode. For RPM calculation I would like to time stamp every transition event i.e. encoder count + timestamp.Timers in use: TIM1/8 - PWM, TIM2/3 - hall...
