Code only executes when semihosting

Posted on June 28, 2016 at 21:11I have a STM32F4 Discovery board. I have GDB connected to OpenOCD and when I run my program on GDB it executes perfectly. When I disconnect the board and program it via ST-Link nothing happens. I tried and older progr...

STM32F4 ADC DMA Transfer Error

Posted on February 06, 2016 at 18:06 I am using STM32F407VGT-6 chips. I use the DMA2 Stream0 with the ADC1 to read analog values. On two of my Boards, the code is working fine and I am not having any problems. On a third Board I programm...

STM32F4 TIM1 DMA CCR1

Posted on June 30, 2016 at 21:57I plan to use the STM32F40x TIM1 CH1 (PA8) to produce a varying  PWM  signal. The base frequency is set, say 1 MHz.  I need to use DMA to change the PWM duty cycle on every iteration. I know this can be done by aiming...

How to clear SPI TX Buffer

Posted on January 02, 2012 at 04:06I am using STM32F103 MPU.I set the board as SPI Slave and uses DMA to receive and send data.Most of time Command comes from Master and Slave responses.So I made code to wait for receiving Command from Master. Once ...

DMA to GPIO output pins

Posted on June 28, 2016 at 17:39I wish to transfer a large array of data to 8 output pins that are all on the same port. E.g. a 500 element 8bit array where each bit of each element represents the pin status.So 500 independent transfers to the port ...

usart baud rate

Posted on June 30, 2016 at 12:38hi i wanna connect stm32f407discovery board to stm32f429 via uart communication. how can I calculate the closest baud rate to 5Mbps for these 2 board? I use following cod and it work but I want to be sure about minimu...
