Hi guys.I am using STM32G031F6P MCU and i want to use UART TX with DMA in slave mode. But it is not working. RS485 line is always busy. I am using RS485 transceiver (SN65HVD37DR). If i use normal (not DMA) transmit mode, it is working. Code and cubem...
Is it possible to configure 1 or more timers to divide incomming pulses on a pin by a factor (for example 8) and send out the result on another pin?Like this:That way I would not need to implement the counter in software.
I'm developing a new design with a STM32G0B1x uC. Therefore, I will use a 12MHz or 8Mhz external (HSE) crystal quartz from Abracon. I just read through the AN2867 and did some calculations. Now I'm at the point where I would need to measure the drive...
I have a FT231XS on my board and a STML451. I would like to communicate over Uart to STM. So i need the FT231XS as USB to UART converter. My software works with NUCLEOL425RE, so when i send some strings over a Serial Port i can receive it immediately...
Hi, I've been looking at timer examples for days and can't seem to find what I need. If I find something, then the interrupt routine isn't listed, for example.I have a precise 2.5Mhz signal that I want to count 25,000 times and then overflow. I don...
Hello,I am a newbie in struct.I have a struct declaration below.typedef struct __serial_data { uint8_t frameStart; uint32_t data; } serial_data; serial_data mydata[25];but frameStart is allocated 32bit in memory and this causes trouble when sendi...
I am using the ADC on an STM32 microcontroller.The ADC is operated in ContinuousConvMode.Can I start it with HAL_ADC_Start and query it at any time with HAL_ADC_GetValue?Or may HAL_ADC_GetValue only be used if it is ensured that the ADC is not curren...
My code runs without issue when the STM Nucleo is connected to the laptop, but if I try to run it without connection to PC, I have to press the reset button before the code will run.I am using STM32CubeIDE and cannot find a solution relevant to that ...
I'm trying to create a firmware application that can be updated via usb in the field, and most of it is working. I can get the microcontroller to enter and exit bootloader mode by, and I have a program to flash a new firmware update to the microcontr...
It seems so easy, but I get no signal to the pin PA4. I use STM32f103VCT, any Idea ?int main(void){ /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all periphera...
