I want to make robotic arm , CNC controller for this purpose which STM32 is capable to do DSP, arithmetic and floating point calculation Faster (less clock cycle for execution)without much execution code delay?So interpolation and trigonometric fu...
We make below code.The variable a is written from both main function and interrupt function.When accessing variable a with the main function to realize exclusive control, interrupt disable and enable (__disable_irq(), __enable_irq()) are used.How ...
I am working on this project and I want to have full control of the sent / received messages from my STM32F746G. Even when starting an empty project without ETH these messages are sent from the STM
int main(void){ /* USER CODE BEGIN 1 */ uint8_t read_opcode ; uint8_t read_addr ; uint8_t Result_read = 0x00; uint8_t Result_read_buff=0x00; char*commande; commande = (unsigned char *) 0x5A; /* USER CODE END 1 */ /* MCU Configuration-----------...
I have a project based on the L496. The application does a few writes to FLASH. The initial write works correctly, however subsequent writes fail. The code is directly from STCube:/** * @brief Wait for a FLASH operation to complete. * @param Ti...
Posted on January 25, 2018 at 14:07Hi,I use STM43L476 and try to use fast flash program to program 256 bytes (decripted_firmware_data buffer).The flash area is erased (all 0xFF), but the function HAL_FLASH_Program always returns with HAL_ERROR and n...
Hi everybody!I'm trying to acquire data from the ADC1 with two channels, and store them in a 40k long buffer with Circular DMA.The problem is the following: it seems that every about 3k samples the ADC stops workinkg for a while and then starts again...
Hello ST Community,I use two UARTs at the same time, 1 to communicate with a sensor and the other to communicate with the BlueNGR-M2SP BLE module.The UART2 is configured with DMA IDLE because the length of the frame I receive varies and the UART1 has...
I have an application on STM32H750 which runs out of QSPI in XIP mode. After init, I enable the cache with SCB_EnableICache() and SCB_EnableDCache(). After this point, the application goes to a continuous loop which just calls the same small function...
