Hello! Recently I got into STM programming for my internship and I cannot figure out register level programming yet, I have this piece of code ```RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN | RCC_APB1ENR_TIM2EN;GPIOA->MODER |=GPIO_MODER_MODE5_1 | GPIO_MODER_...
Hello,I am experiencing the following problem. When I setup an ADC with DMA for 5 channels, occasionally I get lower readings than the expected ones. It also happens in some of our hardware of our production, but others perform ok. We have inspected ...
Hi, I am using stm32u575 uc trying to use independent watchdog for time 1.2 sec for custom board. The clock configuration is as follows: static void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct = {0};RCC_ClkInitTypeDef RCC_ClkInitStr...
Hi,Problem: I'm getting errors when trying to send ttcan time reference messages while FDCAN1 is set to external loopback mode.Description: I have an application where we are using TTCAN effectively with one device acting as a TTCAN-Master and sendin...
I have two nucleo boards communicating over SPI. No Interrupts; No DMA ; Using HAL TransmitReceive(..) Chip Select set by software. Simple 8 char ASCII Transfer. Everything Works....almost. I am using a logic analyzer to monitor the interact...
Hi everybody,I am using STM32F042G6 MCU for an automotive project and since It doesn't have mush FLASH (32kB) I am trying to reduce code size as much as possible.Lookign at the linker file generated by STM32CubeMX, I see that instructions are aligned...
The STM32F429 processor operates at 180MHz, with a clock cycle of 5.56ns. Can we generate pulses with a width granularity of 5.56ns using only ARM instruction delays?For example: 5.56ns, 11.12ns, 16.68ns, 22.24ns?In practice, I have encountered diffi...
Is there a way to reset the counter and the prescaler via a hard event or something when an input capture happens?I use timer 1 to have a hall interface and to drive timer 8. But there are some fluctuations, because the interrupt (where i reset count...
I'm using STM32F407 as a USB host. I have multiple devices in which we are using CH340E as the USB to serial communication. The problem is if that device somehow turns off and CH340E loses its power. The USB Host can not transmit data to the other de...
hi,The datasheet says "In this mode, the TCR flag is set when the number of bytes programmed in NBYTES is transferred"Does this mean that the flag will be set when the data is transferred from TXDR to shift register, Or, the flag will be only set if ...
