Posted on August 03, 2014 at 23:35I am using an STM32F407 to receive data via UART and seem to be getting false FE interrupts. There are two reasons why I believe that they are false: I have looked at the timing on an oscilloscope and it appears t...
Posted on August 13, 2014 at 17:46I am trying to transmit multiple bytes on I2C bus using dma. In the sample code I am trying to send 3 bytes. I see on my scope that three bytes are being sent but the problem is that the first byte gets sent three t...
Posted on August 13, 2014 at 13:50Hi guys,Keil example USB-CDC stuck under load.I just can’t believe such a basic example is unreliable.I’m sure Keil USBstack is widely used in production so I guess I do something wrong.Could you point me what is wr...

Posted on August 06, 2014 at 16:35Hello,I have a board equipped with a STM32F030R8T6. It runs for app. 0.1 s and then goes into StandBy (or should) for 10 seconds. It is woken up by IWDG. It looks like it is working OK, it executes and goes to _som...
Posted on August 13, 2014 at 02:22 I am having some trouble getting the expected behavior out of my interrupts for DMA and USB. Using the STCubeMX HAL libraries, I have configured the interrupts as follows: /** * @brief System ...
Posted on August 12, 2014 at 16:00 Hey, I am trying to communicate with SIM900 GSM module using STM32F072RB chip on discovery board. I have written the code, which works fine for a few commands. I can transmit and receive small commands and I re...
Posted on August 13, 2014 at 00:24I have an exti set up on a gpio, which when triggered, sends a command to a peripheral. Within that piece of code is a small delay which makes use of the systick. It doesn't seem to work though. Guessing the issue i...
Posted on August 06, 2014 at 20:23 Background: - I have a system with two STM32F407 processors communicating via SPI. - I am using the HAL drivers generated by STMCube - They use the same firmware and adjust their behavior into master or sla...
Posted on August 12, 2014 at 20:55In stm32f4xx_hal_gpio.h (delete comment) typedef struct { uint32_t Pin; uint32_t Mode; uint32_t Pull; uint32_t Speed; uint32_t Alternate; }GPIO_InitTypeDef;But to select the alternate function you need 64 ...
