Hello, I use STM32L476 for very low power project. I also use an external RTC because it is temperature-compensated. My question is : What is the best way to backup some bytes whitout RTC backup registers in order to enter in shutdown mode.I had the ...
I am trying to debug my USB and in the process I am going through all the registers defined in the datasheet vs stm32h745xx.h file and I see that in some cases the .h file has registers defined that is not in the datasheetGUSBCFG_CTXPKT : in .h but n...
Lets hope someone has a felicitously revelation, or a clue.I am using a custom board with a nice stm32f105rbtx, fed with external XTAL.Everything worked like a charm untill i configured the clock to be 72Mhz and readjusted the can parameters in CUBEM...
Hi, My evaluate kit is STM32L562E-DK Discovery kit.Is there any example to demo how to implement HID stream driver via USB on STM32L562QE?rgds,QiZhang

STM32F777__HAL_RCC_TIM5_CLK_ENABLE(); TIM5->PSC = HAL_RCC_GetPCLK1Freq()/1000000 - 1; TIM5->CR1 = TIM_CR1_CEN; cyclecountstart = TIM5->CNT; HAL_Delay(1); cyclecountend = TIM5->CNT; cyclecount = cyclecountend - cyclecountstart;I expect to see cyclec...
I want to read from GPIOB in regular intervals into the RAM. After 8 hours of reading blog posts, examples and trying different things I had no success. I am using STM32Cube to generate code and I am using following code to initiate transfer. So far ...
Im trying to do an ADC led counter, but when i debug my program i see the live expression and i can watch the changes in the potentiometer, but D10,D9,D8 AND D7 are on but with 1.8v, and d5,d4,d3,d2 turn on with 3.3v, the main idea is that when i rot...
I'm having a trouble when using multichannel ADC. In my application there is 2 ADC which contains 7 channels. In ADC Interrupt Callback, I'm pushing the read data to array of 7 elements. But I couldn't see the proper value in proper element of array,...
This compiles with no warnings or errors: char buf[256];uint64_t bignum = 0x123456789;sprintf(buf,"bignum: 0x%016llx, %llu\r\n",bignum,bignum);HAL_UART_Transmit_DMA(&huart1,(uint8_t *)buf, strlen(buf));This comes out the terminal:bignum: 0x0000000000...
