Posted on April 10, 2013 at 07:59 Hi Everbody, I'm trying to configure 3 channels of the ADC (Vbat, Temp and another analog input). Yesterday, I managed to read the value of Vbat. Now I would to read the value of the three channels, but I...
Posted on March 07, 2014 at 17:27Hi Hi, I have done some test using the USART1 PA9 and PA10 pin to communicate with my arduino board, i made some basic configuration like this : USART_InitTypeDef USART1_Init;RCC_APB2PeriphClockCmd(RCC_APB2Periph_USA...

Posted on March 05, 2014 at 13:17Hello guys,Can anyone explain me how CAN filters work? I cannot understand the reference manual, I don�t know if I am stupid or it is very bad explained (stm32f407).I read a lot of post on the internet but I have a m...
Posted on March 07, 2014 at 10:40Hi everyone, I'd like to choise STM32 for a HMI case, whoes main requirement was a TFT LCD of 800*480. There were 2 idea: 1) STM32F1 + RA7785 2) STM32F429 Which was the better? Everybody could give me some suggest...
Posted on November 07, 2013 at 16:50 Hello everybody. I need to use LIN communication with stm32 mikrocontroller. I see the std lib have function for lin communication, but the comments in the usart.c file is strange. The lin communi...
Posted on March 05, 2014 at 12:59I'm looking at making a device with the STM32F401, and I'm wondering if USB on it can function without a HSE crystal?The clock diagrams seem to imply that PLL48 can work off of HSI, but the reference implies that USB...
Posted on March 06, 2014 at 12:41Hi there, I want to change the speed of GPIO for STM32f4 discovery board. The maximun speed I can get on specified pin is 6 MHz and I want to get 20 Mhz. we know that the discovery board has external clock circuit to...
Posted on March 06, 2014 at 19:00Hi all, I'm trying to interface a multi-channel ADC to the F4 series over SPI or perhaps I2S. Need to achieve DMA. I have 256 bits. Can I use a NSS signal that is low for 256 serial clocks? Or do I need to burst bot...
Posted on December 29, 2013 at 02:54Hello,Can anyone tell me whether the STM32F429I-Disco board is compatible with the STM32F4DIS-BB's Ethernet? In short, I want Ethernet on the '429 Discovery board.Thank you,-david #discovery-stm32f429
