Posted on June 08, 2018 at 19:30 I'm trying to draw a bitmap using 2D DMA, so I have the address of the destination which is the front buffer, and then I read a line from the bitmap, blit it using the 2D DMA.. I get scanlines, and garbage image. ...
Posted on June 08, 2018 at 21:10My project needs me to connect the host PC to my STM32F4Discovery DISC1 via the virtual COM port to the USART2. So that I can send commands to the Bootloader. Though I have been able to transmit data from the USART3 t...
Posted on June 08, 2018 at 16:37Hi, guys.I am using STM32F437 and trying to use PI8 as an output port.I am trying to program it using standard procedures: RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOI, ENABLE); GPIO_InitTypeDef GPIO_InitStructure; ...
Posted on June 06, 2018 at 14:23Hello,I implemented some functions to read and write the QSPI memory by using functions HAL_QSPI_Transmit() and HAL_QSPI_Receive() provided by the libraries.Everything works fine. I just wonder how I can write and rea...

Posted on June 08, 2018 at 10:48I have a question about a feature of STM32s which slightly puzzles me. Each peripheral class (e.g. SPI) may have several instances on a given processor (e.g. SPI1, SPI2, ...). Different processors in the family have d...
Posted on June 08, 2018 at 10:26Hi All,I am brought a a bunch of STM32L082KZT6 (STM32L082 in LPFP32 pinout) parts and I've started designing my PCB but in the datasheet the VDD_USB pin is omitted (only) for this package BUT ST says it supports USB d...
Posted on May 28, 2018 at 09:05 Im trying to catch data from the unknown device, this device has data and clock. I decided to make my stm32 as spi slave and catch the data as recevier.And im struggling with it. I have this data flow which i want to...
Posted on June 06, 2018 at 13:42Hi!I found setting up an external interrupt in an STM32F103 to be a little bit hard. What is the sequence of to do's? I can find information fragments about the EXTI and NVIC, scattered through the reference manual an...
