Posted on February 15, 2018 at 13:55Hello all,We are migrating from a STM32F42xx processor to a STM32F77xx. As we have a hardware design already done and we want to increase the processor resources, we decided to upgrade our processor to another one...
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...
