Posted on June 26, 2015 at 18:19Hi:I am trying the LwIP TCP/IP stack demonstration for STM32F2x7 microcontrollers based on LwIP TCP/IP stack and FreeRTOS on a STM3221G-EVAL board,(http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1743/LN17...
Posted on June 26, 2015 at 04:01Hello,I am trying to add a semaphore within stm32_eval_i2c_ee.c IRQ handlers for synchronization. The current implementation polls a variable that is modified by the RX/TX IRQ handlers. Here is a link to a post on the...
Posted on June 23, 2015 at 20:02Hello All,I am using STM32F207 to develop ethernet communication. I have to port FreeRTOS on the board. The board is custom no the standard ST EVAL board.I have access GPIO and UART on the board.Now I am using LwIP de...
Posted on December 25, 2013 at 13:34Hello everyone, I have a 'leaf maple' ARM board which I am trying to get the USB peripheral functioning using only ASM coding. I am fairly confident with ASM in general but only have a few months experience with 3...
Posted on June 23, 2015 at 10:16 I made my own bootloader for an STM32L1 board. My algorithm is simple : - first, I erase the memory I need to write my new program on my flash. - then, I write 4 bytes per 4 bytes my new program ( I receive it fro...
Posted on June 22, 2015 at 07:45Hello,We are using STM32F415RG76 chip in one of our products and we are facing a very confusing USB issue. The issue comes when we switch the microcontroller from the bootloader to application-firmware.In some of the ...
Posted on June 18, 2015 at 21:36Hi. I used HAL drive and example from STM32Cube_FW_F4_V1.6.0 on Open429I HW. FatFs reading file from SD card via SDIO sometimes returns FR_DISK_ERR. After the reset program reads four files. Usually it finish OK. Some...
Posted on June 20, 2015 at 18:59Hello All, I have configured the STM32F417VG Ethernet peripheral, attached it to the LAN8720 PHY interface, configured it all for RMII operation, and established a successful link from my target board (STM32F4 Discove...
Posted on June 20, 2015 at 10:54Hi everyone, I need to plot on my PC a signal that has a max frequency of about 86 KHz (i'm using an anti-aliasing filter with that cutoff frequency). I'm working with a STM32F4 Discovery Board. I configured the ADC ...
Posted on November 18, 2013 at 15:54Hi,I am using the STM3210C-Eval board and the STM32_USB-Host-Device_Lib_V2.1.0 Host MSD example.It is working i.e it reads and writes to disk but it is slow. I need to make / save a 2 Mbyte file on the USB.The cod...
