STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on March 15, 2018 at 15:35Hi all,I am about the configure the timer frequency which will trigger ADC to continuously scan and convert 5 channels. The callback will be from DMA.The MCU I am using is STM32F407. System core clock is 168 Mhz. Fpc...
Posted on March 15, 2018 at 17:16I am trying to create a custom external loader for the flash chip used in my product. I have looked the example projects in IAR and created myown. I modified the Loader_src.c and Dev_Inf.c file according to my flash ...
Posted on March 15, 2018 at 16:20To begin, this is a board TEST question rather than a design question: Has anyone successfully generated digital In-Circuit Test vectors for the STM32F4xx families using the Keysight 3070 or Teradyne scan tools? I su...
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...
