Posted on April 28, 2013 at 09:27I configured ADC1 and ADC2 on fast interleaved mode and use DMA for ADC data transfer. I expect that when I call the StartConversion function of ADC1, the ADC2 should be started automatically by ADC1 after 7 ADC cloc...
Posted on April 27, 2013 at 00:26HiI find problems with capateur internal temperature sensor STM32F4 Discovery, I have measured as false (-80.50...-45.00...-60.50 ).I know if my code is wrong or the formula that calculates the temperature.I hope the...
Posted on April 26, 2013 at 18:25HI, I want to know how to convert the values ​​that provides MEMS accelerometer on g because I need to set the threshold for single /double click detect.For example in the program MEMS in STM32F4-Discovery_FW_V...
Posted on April 27, 2013 at 13:07Hi all, I've the following problem. I need to measure signal on the PC.00 pin and with the code bellow it doesn't work. :( However, if I change the pin to PC.02 and Channel 12 , everything works fine and I get the pr...
Posted on April 27, 2013 at 08:12I am using stm32f107rc for rs485 communication through usart1 and usart3. i am receving a set data from usart1 to an array and trying to transmit the same set of data from an array through an usart3. it works fine fo...
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 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 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...
