Hello,i currently use SPI interface of my STM32H7B3I board with DMA (mode circular) to build up a connection to Raspberry Zero W (using Python spidev-lib).At the beginning, I start HAL_SPI_TransmitReceive_DMA() where the data exchange is initialized....
Hello All,If I pass 0x38 hex value into my function, that should be came out from my one of the port as parallel data, how to do this ? please give me a simple example with code and explanation.My youtube channelStm32user
Hello, I have several modules with STM32F103C8T6 (called Blue Pills). But I cannot get them to runthe programs. I can freely write or read flash memory with stm32cubeprogrammer, but there is always warning (even when I want to start the program), tha...
I've got the following structure to write to memory:```#define FLASH_CONFIG_START_ADDR ((uint32_t) 0x080E0000)#define FLASH_CONFIG_END_ADDR ((uint32_t) 0x080E0040)union NVRAM { Config_t config; uint8_t data[512];} DevNVRAM;```I've used this code for ...
I was trying to write a simple UART driver using polling method to run on my Nucleo-F303RE. I tried 2 different approaches:I wrote the function intpolldriver() to write an integer value between UART4 and UART5 in the main.c, called it in main() and c...
Hello all,I'm trying to implement a really simple exercise:Send a char via USART2 (PA2);Receive the char via USART1 (PA10);After the char is received, within an interrupt I increase a variable called "Debug".The only HW connection done is that betwee...
Hello everyone i was wondering if STM sold microcontrollers with bluetooth integrated into it. Please do let me know the names of the chips Thank you
I'd like to use TIM14 to time some events but only using software capture triggering. I'd like to setup TIM14 to count continuously through its whole range and use the CC1G bit in the TIM14_EGR to capture the timer. I'd like it to ignore TI1 or disa...
Hi.I am having problems with the ADC, for some reason, it only works when I put a breakpoint in the function I use to enable the ADC to debug, but, if I run it without any breakpoint, it does not work.line of code I use to extract a value from the AD...
Hi,I'm new to STM. I've been learning to program, but finding it difficult to display logs on the screen of STM32F746G Discovery board.I'm not sure if I'm on the right direction. Basically I want data from UART_Receive with interrupt to be displayed ...
