Hi,I have to read a sequence of five ADC channels each 100us. In the past, I used the common way by DMA channel 1 and an interrupt at reading completion to get all values. Unfortunately I need most of the DMA for other purpose this time and I'm wonde...
Hello, I'm new to embedded software and I have 2 questions about UART communication.I've coded UART interrupt and have no problem with the transmit function, but the HAL_UART_Receive_IT(&huart2, rx, 10);only read the first byte I passed to the serial...
I've configured my STM32F303RE to send the COMP4 to the output (PB1) as well as to TIM4_Ch2. I also am running an external signal generator in from PB6 to TIM4_Ch1.I can see the COMP4 output on PB1 but not at the TIM4_Ch2. I can see the external sign...
I am trying to set up FMC to work with external RAM. The code compiles and works with KEIL, but I am trying to make it work with STM32CubeIDE. The code compiles and runs, but the RAM is not initialized. I copied all of the code, including the .ioc fi...
Hello,I'm working with the NUCLEO-F722ZE EVB on STM32CubeIDE.I want to use the main USB connection to the PC as a UART.The default CubeMX pin configuration already has PD8 and PD9 configured as a UART, so I proceeded with code generation (the auto ge...
I am currently designing an application where I will read Sensors that can be integrated over time (e.g. Accelerometer, flow meter). As a first step I want to calculate whats the maximum error I could get by using the cycle counter as a unit of time....
Helllo,I'm working on the NUCLEO-F722ZE EVB.I want my code to wait for a character to be received from UART 3 and do nothing.This is what I wrote:unibt8_t received_character = 0 ; HAL_UART_Receive(&huart3, received_character, 1,1000) ;From what I und...
