I am considering powering a STM32G4 with a DC-DC Switching Converter. One of the converters I am looking at has a PWM Switching Frequency of 6-MHz, the other 500 kHz. I'd use a hefty inductor and capacitor to filter the current ripple at this PWM fre...
Hello,which points of SDIO (DMA) settings i have to look for if my f_read reads only half but counts full.Example:uint16_t buffer1[1024];f_read(&file,&buffer1[0],1024,&cnt); buffer1 is filled with values to buffer1[511] but variable cnt gives me 10...
I am doing some characterization study for the cache behavior on STM32F7508. The result is hard to understand.Below is a simple code that I use. I align the array A1 to the cacheline (aligned(32)), and it is placed on SRAM1 above TCM (0x20010000~ ) w...
Hi, I have a design where I have multiple GPIO interrupts and some share the same interrupt input line, for example EXTI10_15. How can I differentiate in the interrupt callback routine which GPIO triggered the interrupt aside from reading these GPIOs...
Hello together,currently I'm facing a very strange issue:I'm working with an STM32F777.One GPIO of the MCU is used to enable the voltage to a sensor. This pin is initialized as GPIO_InitStructure.Mode = LL_GPIO_MODE_OUTPUT; GPIO_InitStructure.Outp...
Hi, is there a way to change LPTIM_CNT on TIM4 so that LPTIM_CNT = LPTIM_CMP, this is because for every interrupt we need the PWM to skip some period. is there any sample code ?
In our current project, we are using the STM32G431 (UFQFPN32) with only an HSE connected. In this project, we do also need a longtime accurate RTC for Time/Date. Since the internal LSE have a quit high accuracy of 1%, they dont seem to be suitable fo...
Hello, second day try to launch UART in LIN mode.Task: waiting break, when break flag set up, switch on DMA receiver.Transmitter works fine and send 100us break before frame.But receiver can't set UP Break Flag.And there are not everywhere examples =...
Hello,I am trying to generate a unipolar PWM-Signal with an STM32f103RBT6. The Current needs to be sampled at a specific point in the PWM-Cycle. Due to the unipolar nature the current cannot be sampled at overflow/underflow. Instead it needs to be me...
