So problems with stm32h743VIT6 SPI TX.No TXC/EOT -flag(s). No TX interrupts. No physical activity on pin side MOSI/SCK.Like commented to code: I have tried so many variants of configurations (only master transmitters). I feel I have tried all what I ...
I have inherited code that received 1400 bytes over a 2mbps serial link. I've increased that to 1892 bytes and on occasion (not always, but frequently enough to be annoying) I receive my buffer "shifted" by one byte and a garbage byte for byte 0 in t...
My development board "NUCLEO-401RE" has forgotten the original name of the virtual disk.As a result of various projects, the original name "NODE_F401RE" changed to "NUCLEO".I do not know when.The board is working properly.However, the Teseo-Suite Pro...
int16_t GetTim4Encoder(){ Tim4Encoder = __HAL_TIM_GET_COUNTER(&htim4); //__HAL_TIM_SET_COUNTER(&htim4,0); return Tim4Encoder; }
In a noisy media, I need to receive 10bytes with DMA (about 1Mb). I have set the DMA and its interrupt as shown below:void DMA_Configuration(void) { DMA_InitTypeDef DMA_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE); ...
Hi, community:I'm working on a custom board based on a STM32F7 MCU,which I have use the MCU is STM32F750Z8T6 and spi flash is W25Q064AJVSSIQT(Winbond).But the assets (images, font ...) are too large to be loaded into the memory of the MCU and have to...
Hi everyone!i have an issue with communication! As shown below, when I press the green button I want to toggle led on the IoT board & when it’s the red I want to toggle WiFi ble led( I didn’t find an other user led)if i press the red button it works ...
The STM32F303RBT6 ADC2_IN3(PIN PA6) is connect to GND .When the pin PC4 set high,the ADC_IN3 read a abnormal data 0x70. When the pin PC4 set low,the ADC_IN3 read a normal data 0x00. Which the PC4 set high,is affect theADC2_IN3 sa...
Hello,I have a doubt about the amount of SRAM available on the STM32H7B3.In the datasheet it is indicated 1184kB (setion embedded SRAM), but the linker script indicates 1024kB.In the datasheet, there is not much detail on this.My goal is to use for a...
