Posted on February 28, 2014 at 23:00Hi, i'm newbie on stm32 and i have some questions about it ! I have f3discovery and i would like to communicate with my pc by usb ! I want to send to my pc the angles values of the gyroscope. On my pc i use Qt. I ...
Posted on March 08, 2014 at 04:04 I'm working with USART2 on the STM32F439 and when I enable the USART2 the RX Pin connected to PA3 pulls high to around 500 mV.I have initialized PA3 for the USART2 RX Pin as shown below. This pin is connected to...
Posted on March 07, 2014 at 18:23Hi. I'm writing a pc tool for flashing STM32F407 using USART. I got familiar with AN2606 (bootloader) and AN3155 (USART protocol). One thing I don't know is the BIN file specification. Can I just write to STM32 the c...
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...
