Posted on September 25, 2012 at 00:36When I use DMA on the transmit SPI2 chanel (STM32F205) I consistently get FIFO errors at the end of the transfer, even though the FIFO is disabled. I verified the DMDIS flag is 0 in the DMA_SxFCR register but th...
Posted on June 10, 2014 at 04:55The scenario is as following:1. Data is transferred by DMA from a camera or from an ADC via SPI to SRAM2. Computation should be performed based on the incoming data.3. The computation includes multiplication with look...
Posted on June 10, 2014 at 22:51 Hi all; I'm trying to make two boards communicating with SPI. The Master is a board based on PIC µC and the slave is Discovery F3. The protocol that i have to establish is as follows: 1) The master...
Posted on September 23, 2012 at 12:34Hello. I colided with the following problem: ADC1 doesn't start conversion in injected channel from TIM1 CC4 event. Below I quote a piece of code of my initialization of ADC1 and TIM1:RCC->APB2ENR|=RCC_APB2ENR_TI...
Posted on June 11, 2014 at 11:53Trying to generate a simple PWM Output using STM32-Mat Timers 1 and 8 work flawlessly, however the other available timers (2,3,4,5) all produce error 6200: TIMx-IRQHandler multiply defined by stm32f4xx.o and PWMTest.o...

Posted on September 05, 2012 at 11:16HiI've downloaded in the MCU TIM complementary signals example, provided in the ST Peripheral examples. PA8, PA10, PB13, PB14 and PB15 are working correctly. However, PB12 (whose complement is PB14) is displaying...
Posted on June 06, 2014 at 15:42Hi AlI have referred to AN3966 (LwIP TCP/IP stack demonstration for STM32F407/STM32F417 microcontrollers) to get LWIP stack for Standalone STM32F407VG. And also i got LWIP stack files from a link http://www.st.com/we...

Posted on June 10, 2014 at 16:34 For several years I have developed software for an STM32F103 target using Eclipse/OpenOCD/Olimex ARM-USB-OCD. Recently my hard drive failed so I replaced it and re-installed everything. My project will not now ru...
