Hi, i have an application where i have to read data and store in a buffer, now the buffer length depends on the data_len byte once received from the slave. Than is it wise to use Malloc/Calloc functions? Basically is the dynamic memory allocation sup...
Hi All,It will be much appreciated if i can get a hints on how to obtain bsdl file of stm32h755xih6 I download the bsdl files of the family en.stm32h7_bsdl . (in web indicate that it include stm32h755xih6) but in reality dont have. This IC have a 265...
Hi all,I'm using stm32l431 and met a problem as below.After power up a new stm32l431 board which had not been programmed before, the MCU enter bootloader progam and the PC value is 0x1FFF xxxx. Downlaod my own code to MCU but the code and not run.Th...
Hi everyone!I'd like to use the HRTIM Master Timer Period on my NUCLEO-H743ZI2 to trigger a synchronous Burst DMA Update to HRTIM TIMA, TIMB, TIMC Compare Match registers.Two timer Outputs for each timers are supposed to generate a PWM and Inverted P...
Hello, I am currently developing an MCU based radar. I tried to implement 4-channel ADC Sampling 1MSPS based on STM32H743, but the results were not good. There are many problems, but the biggest problem is the sampling rate, so to solve this, we plan...
Hi together,I am communicating over different interfaces and these are from different suppliers. There it is used the CRC-8 algorithem to secure the the communication data.I have two cases, in both we use a table to realize the crc calculation, now I...
I am using STM32H747 Discovery kit. Using FreeRTOS, trying to understand if SysTick->VAL is it in Micro-second?
I would like to use NUCLEO-H753ZI (STM32H753ZITxLQFP144) to do the following:・Use ADC1 and ADC2 to start acquiring separate signals in a circular buffer at 1MSa/s. (The time of each ADC is synchronized.)(1) Start ADC using the following functionFunct...
Hi there!First time on the community, but have been programming with STM32s for some time now. I am currently facing a speed challenge using the HAL_SPI_Transmit() function. In order to toggle the CS line, I have always done something along the lines...
Hello,I'm just started using a nucleo-h742x. I have configured the SPI and the Fatfs library using the default settings, the SPI speed was configured at speed below 1Mbit/s. The sys clock is below 100MHz.I always get disk_not_ready error when trying ...
