Posted on April 16, 2013 at 12:40I have an input 8 bits parallel bus, with a CLK signal connected to GPIOs. The frequency is 1MHz. I need to configure an automatic DMA transfert from the 8 bits GPIO to a memory buffer (dual buffer mode would be grea...
Posted on April 19, 2013 at 16:43 Hello, I'm quite a newbie with USART RX, I read a lot of code examples but I don't exactly understand how it works. I want to receive MIDI data from a musical instrument. MIDI is a protocol using USART c...
Posted on April 29, 2013 at 01:00 Hello here, I'm trying to reset USB peripheral before entering stop mode, on an STM32F But if I do so, the RTC (which runs from LSI) stops .. Any idea why ? Here is the code : ...

Posted on October 26, 2012 at 10:57 Hi Guys, Been trying to get the USART to work for a couple of days now and is time to get some help... This is my code: GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStru...
Posted on April 28, 2013 at 07:51Hello, I want to use UART + DMA to receive unknown length packet. So I tried to use IDLE interrupt to monitor the end of the packet. On the other hand, I use a PC tools to send several bytes data and delay a w...
Posted on April 25, 2013 at 20:46Hello, I am a first time poster on this forum so please bear with me. I am using CMSIS to get the DAC peripheral to play a simple tune. I am working off an example I found online which I have simplified to play onl...
Posted on April 27, 2013 at 17:44 Hello, I'd like to use 4 channels of TIM5 as independent pulse counter, but CCR1..4 seems to have some non-sense value. Here's the code: void TIM5_Init( void ) { GPIO_InitTypeDef GPIO_InitStru...
Posted on April 26, 2013 at 23:57Hello,I'm astudent of computer engineering, I'm trying to interface a STM32F0_Discoverycard with an LIS3LV02DQ accelerometer using the SPI protocol, but I'm havingtrouble with the initialization of the pins of the ST...
Posted on April 26, 2013 at 22:54 Hello, I'm trying to count pulse on PB7 using timer TIM4 ch2. Everything is ok, but I'd like to reset CCR2 so I can start another measure. I tried with TIM_SetCompare2(TIM4, 0); but CCR2 isn't set to 0 after execu...
