We are porting code from a STM32L4P5, where we relocate the IRQ VEctor Table with memcpy(g_RamVectorTable, g_pfnVectors, sizeof(g_RamVectorTable)); __HAL_SYSCFG_REMAPMEMORY_SRAM(); // not implemented on STM32L5xxthat works fine, but as commented ...
Hi, i am working on signal wave generation on the STM32L053 Discovery kit. I'd like to see the maximum frequency of signal generation (a sinus with 100 samples using DMA). But the problem is : i cannot reach over ~20kHz, which is not even in the ultr...
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 ...
