Hi,I am using STM32F205 Board for our development. We were using HSI (16MHZ) as the clock and found out that HSI has issues with high temperatures. I am calibrating HSITRIM value to fix the clock drift issue and we already have 50 boards manufactured...
Hi,I'm working on stm32l496 and I try to write data to a custom flash section, in the .ld file I put new sector :/* Memories definition */MEMORY{[...]FLASH (rx) : ORIGIN = 0x08003800, LENGTH = 0x07B800config(rx) : ORIGIN = 0x0807F000, LENGTH = 2Kcomm...
Hi,I have a board with an STM32U575 at the core.I'm attempting to set up SAI receiver in I2S mode, with 32-bit 48kHz sampling. See my configuration of SAI A below: I also want to receive the data continuously in circular mode via DMA (or GPDMA in th...
static uint16_t aDST_Buffer_1[BUFFER_SIZE] = {0}; static uint16_t aDST_Buffer_2[BUFFER_SIZE] = {0}; LL_DMA_LinkNodeTypeDef pNode1, pNode2; /** * @brief LPDMA1 transfer configuration * @PAram None * @retval None */ void BspLPDMA1Init(void) { /*...
I am starting a product design tentatively using the STM32F072RBT6.I want to determine how soon the CTS input must go low to prevent the USART from transmitting the next byte.Even informed opinion would be appreciated; but a reference to documentatio...
Hello,I'm trying to work with the ADC of the STM32L433 microcontroller. The Reference manual (RM0394) on page 448 it says : The following formula gives the actual VDDA voltage supplying the device:VDDA = 3.0 V x VREFINT_CAL / VREFINT_DATAWhere can I ...
Hello,I will use stm32g473VC ADC2 working together with DMA.I configure ADC2, Input3 at Pin PA6 and DMA2 Channel1 to read 100 Samples from ADC after Start.At first call after cpu reset I receive the expected result:ADC:Value 4034 for Items 0->99, as ...
Hello,I have designed a PCB with 3 STM32H725VGT6 MCUs, and assembled them according to my schematic:(sorry for this resolution, this is from a converted pdf)All 3 MCUs are the same, from this schematic.R5 and R2 are just 0R jumpers to select the boo...
Looks to me like the FDCAN peripheral has a few registers that are marked 'r' when they are likely 'rw' in the RM. They are the registers that configure the size of the FDCAN messages. This isn't blocking my work; only thought the ST team should know...
Trying to implement a composite HID device on STM32F042 (or maybe STM32F072 as both Flash and RAM usage seem insane), starting from the MX mouse middleware. After much scratching around it's finally working as a mouse and keyboard and I now need to a...
