Posted on August 06, 2012 at 12:22Hello, i am working on science project involving fast calculations for laser stabilization. I need to calculate complex FFT and get phase of second maximum in spectra (first will be 1/f noise, second should be right...
Posted on July 25, 2012 at 13:52Hi, I am developing an application for the STM32L151QC device using gcc and my application needs the facility to perform In-Application Programming. The application update will be contained in an external hardware mo...
Posted on August 03, 2012 at 10:43 Hi gents, We're using a STM32F217IGH6, in a Silica Xynergy board, and we're experiencing some strange issues with the RTC. The code regarding RTC is: static void rtcConfiguration( void ...
Posted on March 13, 2012 at 16:47Hello! I have a question to STM32xx chip manufacturers. Last yar I uses STM32F10xx chips in my applications. It's 8mHz HSI works perfect - stable, with small temperature sensistivity - works very well. CAN bus (slow...
Posted on July 27, 2012 at 21:29hello, I have an issue. I'm using the stm32f103RB. When i want to create an array which has 8192 elements - const uint16_t table[8192] = {458,542... }; The software successfully build in to the flash, but when i'm st...
Posted on March 07, 2012 at 11:12Hi, I develop a project on the STM32F4 discovery board and I want use a MicroSD card. I work with Atollic TrueStudio for STM32. So I search a driver to use my MicroSD card with SPI. I have an API to FATFs and an API ...
Posted on August 02, 2012 at 13:07Hi , i've a problem, i don't manage the sending of the UART signal in correct manner using stm32f4 discovery. I've need of the correct procedure to send Uart signal. Every help is accepted. Thank you. #stm32-di...
Posted on July 31, 2012 at 17:28Hi all, To begin I have compiled AN2790 and AN3241 application note, to try understand logic code. These notes explain how use TFT with firmware ST. I have several questions about it. Is it possible, to display a pict...
Posted on August 02, 2012 at 16:49I'm trying to make a custom drive based on MCS driver; In order to run a STM32F4 (on a discovery board) as USB host of a vendor specific device.Using USBH_BulkSendData I have exchanged data in OUT direction with suc...
Posted on August 02, 2012 at 07:05Hi, I have a query about STM32 External Interrupts. STM32f4 has 16 External Interrupts. But the problem is there are only 5 Interrupt Vectors available in the ST firmware library. EXTI0_IRQHandler(void); EXTI1_IRQH...
