its just have a predefined function eMBErrorCode eMBInit ( eMBMode eMode, UCHAR ucSlaveAddress, UCHAR ucPort, LONG ulBaudRate, eMBParity eParity ) how it will take my USART3 to communicate as modbus ?
While bringing up DMA on H743 in my code, I painfully found out that specifying a wrong memory region as DMA target, like ITCM for DMA transfers, will also set a FIFO error and abort transmission. RM0433 should mention wrong SRAM source or target re...
Hi there,I am looking to design a custom HID device using STM32CubeMX and TrueSTUDIO on a STM32F411E-Disco board. However, i can't find any good examples online for custom devices and how to get one working. I was wondering if anyone could point me i...
Hallo. I'm using SPI and DMA on a STM32L433, to receive data from an external board, and I would like that an interrupt was fired at reception of the 4th byte.I've set the SPI3 (that is in slave receive only mode because I'm using MISO pin for other ...
I have STM32F765, did the configuration in CubeMX.I did try to receive with:uint8_t testData[10] = {0,}; HAL_StatusTypeDef status = 0; status = HAL_UART_Receive(&huart4, testData, 5, 2000);This did not work, status was HAL_TIMEOUT(I did try Receive_I...
Hi,I used ADC Scan Conversion Mode + DMA to read the values from 7 channels of ADC1.But the adc reading values are not correct when I enable the cache./* Enable I-Cache-------------------------------------------------------------*/// SCB_EnableICac...
Hi,I would like to scan 7 channels of ADC1 using multichannel conversion method.Since I want fix sampling rate for all channels, I use timer... But I cannot read ADC value when I set timer value for 200KHz.Please guide me how to configure 7 channels ...
Hi,Is it possible to find a source for project code that is mentioned in the note AN3411? I am looking at the details of lwip and ptp stacks. I working on using IEEE1588 capabilities in my project.Thanks
I have only been able to increase it up to 600 KHz. I have studied the speed the ADC peripheral should have and should be even higher, it can be set at up to 84 MHz, with a prescaler of 2 and 6 bits of conversion should be 9 cycle clocks, resulting t...
Hi all,I am using an stm32l433rct6 (tqfp64 package) in a project and am trying to reconfigure the boot0/PH3 pin for input, but this doesn't seem to work. I can configure the pin as output, which works fine. But when configuring for input, the pin alw...
