I have tried to set the buffer for receiving data a location where DMA can reach(uint32_t dcmi_data_buff[2560] __attribute__((section(".ARM.__at_0x24040000")));). But every time I start DMA I got the same data and once I changed the location for buf...
Is it possible to program an empty STM32F042 using UART1 instead of SWCLK-SWDIO?I want to flash programming of STM32F042 which is zero.
Hi. everyone"I've found that when I enter sleep mode, my uwtick stops counting, which causes issues with calculating the DataCollect time after waking up with the RTC. Is there a way to resolve this?"while(1){ if(HAL_GetTick() >= Tcmd1_dataCollect...
My interrupt is able to be triggered when my variable SIZE_OF_ARRAY is 10. However i want to be listening for large amounts of data so i change it to 1000 and my HAL_UART_RxCpltCallback function doesn't get called. Any idea why this is? I am using ST...
I am running into an issue with the STM32G0B0 MCU: Writing to PD1 seems to result in the opposite value being somehow applied to PD0, even though PD0 is set to input.Effectively, I created a new project in STM32CubeIDE, configured PD0 & PD2 as GPIO_I...
I want to capture several PWM signals, i.e. measure the pulse widthThe reference manual gives an example for TIM2 TI1 that uses channel 1 and channel 2 to measure pulse width and period. Therefore SMCR.TS bits are set to use filtered TI1 as trigger/r...
I tried to use this board to capture image by using DCMI DMA with a ov2640 camera. The problem is data read is successful in DCMI(by watching the register) but the buffer(initialized:uint32_t buffer[16000]={0}) used to store the image data was the sa...
Hello everyone,I hope you're all doing well.I'm currently working on a project with the STM32F103RET6, and I've encountered an issue when writing data to a page of Flash memory. I'm using the FLASH_ProgramHalfWord function to write half-word data. Wh...
Folks,Does HAL have constants for the total number of ADC channels? I want to iterate through all channels and make sure that all of them are disabled. Here's the code I have in mind. ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Rank = ADC_RAN...
