Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Posted on February 15, 2018 at 11:24I'm using stm32f217 controller for my project where i have to interface with tlv320aic1106(pcm audio codec), which requires mclk of 2.048 Mhz and a pcmSync signal of 8khz,But when I tried configuring the i2s modul...
Posted on February 13, 2018 at 11:14Hi,I am planning to use a 25MHz crystal as HSE Xtal for STM32f107 and route the same 25MHz Clock as MCO out to drive the ethernet PHY Chip -LAN8742A.From LAN8742A, 50MHz RMIIREFCLK is fed back to stm32f107 EMAC. ...
Posted on February 14, 2018 at 00:10Hi,i want to write some text from my main Loop on my USB Stick. How can i trigger and Transfer my Strings from the main Loop to my usb_host thread?I can write text in my usb thread. It's triggeres from USBH_UserPr...
Posted on February 12, 2018 at 15:29Hello,I have generated project from STM32CubeMX, FreeRTOS and Ethernet. I have working Ethernet with websockets, SDIO SD card and SPI1.On SPI1 bus I use optocouplers for galvanic isolation and I need to use the sl...
Posted on May 24, 2016 at 17:37 Hi, I am tring to initialize Ethernet with LWIP on STM32F To configure it I used CubeMX, but it can not pass this loop: /* Wait for software reset */ while (((heth->Instance)->DMABMR & ETH_DMABMR_SR) != (ui...
Posted on October 31, 2017 at 19:18I'm using STM32CubeMX to generate code for a custom STM32L051R8T6 project. SysTick functions as expected when HAL drivers are selected. SysTick does not work if LL drivers are selected. Is there a reason why STM...
Posted on February 10, 2018 at 09:44Hi,I am trying to migrate from STM32 Standard peripheral libraries to HAL libraries. I have few queries here:1) Can i use HAL libraries with Keil without first creating project in CubeMX? I just want to build my...
Posted on February 05, 2018 at 13:23Hello, I'm facing a difficulty using CubeMx generated code with USB (CDC with VBus sensing).HAL_GPIO_EXTI_Callback is declared as 'weak' so for managing some GPIO's interrupts, I declared my own call back to 'catc...
Posted on November 28, 2017 at 04:08Dear there, I'm using the Nucleo STM32L031K6 EVK as a 12MHZ SPI slave in my application. Now I found it takes about 60ms from VDD ready to finishing excetution of below code snippet so the SPI slave misses some cm...
Posted on May 29, 2017 at 16:50I believe there is a bug in the osMailCAlloc function from cmsis_os.c V1.02 (STM32Cube_FW_F1_V1.4.0).The function will always assign 0 to the first 4 bytes of the block, since sizeof an uint32_t is 4.if (p) { for (i =...
