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...
Posted on December 07, 2016 at 10:13Hello all,I am trying to program stm32L152 to interface with LS013B7DH03 by using HAL. Its been more than two weeks I am trying to do this (I am quite new to ARM) but not getting proper way to do it. Would anyone ...
Posted on December 06, 2016 at 20:42Hi.I started to work with STM32F7 series and USB HS (CDC class). I am able to send data to PC using CDC_Transmit_HS(uint8_t* Buf, uint16_t Len) function, but I am not aware what is going on behind it. If let say, ...
Posted on November 26, 2016 at 00:33Hello,I'm working in a custom bootloader. I have follow many discussions here and then i end up with this code.commenting the function PerformFirmwareUpdate() the code works ok! pFunction appEntry; uint32_t appS...

Posted on September 11, 2014 at 17:24Dear Friends, Hi,I want to get an interrupt by receiving each character on UART port. How can I use HAL_UART_Receive_IT() and HAL_UART_RxCpltCallback() functions? When I call HAL_UART_Receive_IT() function its ca...
Posted on November 28, 2016 at 23:46Configuration: STM32F107, Linux PC, VCP library provided by STM. Received data is buffered from interrupt and reading within RTOS task context. When resetting device, it's start to be visible as /dev/ttyACM0. Ok. ...
Posted on November 27, 2016 at 17:10HiI try to send data over a VCP USB interface from my STM32F446RE to the computer. I use a C♯ programm with a SerialPort interface to read the data.Under Windows 7, 8 and 8.1 everything works perfectly fine but on...
Posted on July 24, 2015 at 22:27Hi. Let me describe the situation. I have to do 8 AD conversions (using STM32F103) as fast as possible. Thus, I'd like to use ADC in DUAL mode to execute 4x2 conversions (on ADC1 as master and ADC2 as slave) and trans...
