Posted on December 11, 2016 at 03:15Hi.I am developing for an STM32F4. I'm using STM32CubeMX and System Workbench for STM32. I'm using FreeRTOS. I would like to know how I should, and should not, be using the STM32F4 HAL Driver callbacks. As an exam...
Posted on December 09, 2016 at 09:39I have designed two different data acquisition boards with STM32F407 MCU. Everything is OK. Now I would like to customize the USB CDC driver. I changed the MFG name in the .inf file provided by ST. This works in W...
Posted on February 14, 2016 at 16:01Hi,I tested the official USBD MSC exemple with a stm32f746-disco board in HS mode, and I got a very bad speed. For several high speed sd card, I got write:400KB/s, read: 1.6MB/s.Then I tried to increase the MSC_ME...
Posted on December 09, 2016 at 21:31Hi,I'm trying to read SD card using Mass Storage Protocol via STM32F746-DISCO board. I found example in Applications\USB_Device\MSC_Standalone which does exaclty what I need. However the read/write speed is bad. I...
Posted on December 08, 2016 at 22:38Hi all, I'm working with Ethernet on an STM32F745IETx and with a project configured using STM32CubeMX. We're using an RMII interface to a chip that supports three Ethernet ports. I've tested pass through between t...
Posted on December 08, 2016 at 19:27Hi everyone,I'm trying to use the STM32F429-Disc0 board with CubeMX as a CAN to USB bridge but I'm running across very strange behaviour now.I've made it to the point where the device gets enumerated correctly by ...
Posted on November 27, 2016 at 03:51 Anyone figure out how to run the examples downloaded with Cube ? I am using the f0, r8 chip with the nucleo board. I have been programming using bare metal (registers) and some spl to learn about the chip. No pr...
Posted on December 08, 2016 at 09:38 I'm trying to send data by STM32f103 to an Arduino board using UART. Data isn't received properly. The code is generated using STM32CUBEMX and here is the part I added: uint8_t Test[] = '1 2 3 4 5 6 7 8 9 1...
Posted on March 14, 2016 at 08:11 Hi all, I configure the STM32L476 as USB CDC device. It works by PC sends bytes like 256 length to embedded, and embedded side sends big data to PC is OK. However, when the PC send data like 2048 or 512 ...
Posted on December 07, 2016 at 19:16Hello !I did implement a fast transmit queue successfully for serial port printing. That works well with a development board. But in my real circuit, the TX pin is driving the LED of an opto-isolator. The result i...
