Hi, team, I am work on stm32g030f6's uart dma. And config them as idle interrut mode to receive data.When the uart data on high frequence like 10bytes/30ms , the CNDTR will be aways MY_BUFF_LEN -1 , so i only can receive 1 byte data. After reset the ...
Hi All,I am using STM32F74xxx.I need to count micro seconds. currently we are using HAL_GetTick(), function but it gives the time in ms.After I searched on google I found some ways to get micro seconds count, and I tried it but no luck.can any one he...
I work with STM32H753 through 3-rd side hardware (Algocraft WN-1 programmer) and have an access to the registers. I try to read/write GPIOJ pins. For this purpose I enabled GPIOJ clock by writing the AHB4 peripheral clock enable register (RCC_AHB4ENR...
Dear Community Members & STM32 fans,Peculiar year it has been, 2020 comes to its end. This is an opportunity to say "Thank you" because:you don't hesitate to bring help to othersyou help us improve our STM32 offeryou have confidence on ST Communityyo...
it seems that a write to AXI SRAM very shortly before a system reset (via AIRCR) gets lost. I wrote a very short block of code that simply reads a word from 0x24000000, increments it, writes it back, and resets the processor. I can see that the value...
I am using STM32H743BI controller. I need to use backup RAM as nonvolatile ram. So I use external 3V battery and LSE 32.768 crystal for RTC. RTC works well but I can not use backup RAM. I use code like below;PWR->CR1 |= PWR_CR1_DBP;while(((PWR->CR1 &...
Is there any part from STM which able to operates as bluetooth HID keyboard as well as bluetooth touchpad?
Hi :) So I keep reading everywhere that leaving a CMOS input pin floating is bad because it is high impedance, can oscillate, etc. I understand and agree.But while a MCU is starting up (or when you're programming it) all its pin are in input state un...
Hi, I have a STM32F407 board that is running as a full duplex slave. it receives data from a Raspberry Pi configured as a SPI master. Is there a way to receive data from the RPi in a non-blocking mode? One way I could think of was to set the CSN line...
void TIM1_UP_TIM16_IRQHandler (void) { volatile uint8_t t; uint32_t sr; sr = TIM1->SR; sr &= ~TIM_SR_UIF; gpio_set(TIM1_PORT, TIM1_PIN); gpio_clr(TIM1_PORT, TIM1_PIN); TIM1->SR = sr; while (TIM1->SR & TIM_SR_UIF); }Above i...
