Posted on November 06, 2017 at 11:11Hi, I generated a simple LWIP/UDP project for the NUCLEO-H743ZI using the STM32cubeMX. But the function HAL_ETH_Transmit(&heth, &TxConfig, 0); returns with DMA error . My board works using the example from the S...
Posted on October 05, 2017 at 22:44 I need to read variable length strings from a usart. The strings may be the result of local programming or not. I'm using the HAL DMA receive driver under FreeRTOS. I've found that the following approach works:...
Posted on March 15, 2018 at 14:51I have successfully implemented an initial I2C bus (I2C1) in my custom board design (using STM32F405). I then added a second I2C bus (I2C2) to my design and have initiated it and set it up identical to I2C1. The fi...
Posted on March 15, 2018 at 10:31Hi clive,I am using a 32 GB SD card,My code by using the API f_getfree() is as follows:if (f_mount(&myFATAFS, SDPath, 1) == FR_OK) {HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_12);f_getfree('1:', &Free_clust, &myFATAFS);tot_s...
Posted on March 09, 2018 at 07:59Hi I am storing files into SD card using the SDIO interface. I am using a 32 GB sd card. Now i want to check everytime how much space is available on the sd card. Are there any API's available to do this? I am using...

Posted on March 14, 2018 at 08:09My product with stm32l073vbt6 ran 1 week or longger,the mcu was broken.All io and peripheral on broken mcu can run as normal,But the power consumption up to 100mA not 100uA!I have removed all other part but mcu and s...
Posted on March 15, 2018 at 07:40I am using stm32f103r8 and I need to use VREFint Channel to calibrate ADC.But I cant find ROM address holding the VREFINT_CAL value.I look both reference manuel and datasheet.But I couldnt find.#stm32-f1
Posted on March 15, 2018 at 08:06Hi, I am using a STM32LO72 device and entering stop mode using HAL_PRW_EnterSTOPMode ( PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); I have configured the RTC AlarmB to wake the device but it wakes almost...
Posted on March 14, 2018 at 13:58Hi All,Iam trying to configure STM32F4 discovery board to detect as mouse in Windows PC.I have generated code from STM32CubeMX tool and configurations are HSE_VALUE = 25MHZ, usb device class is HID. When Am running c...
