Posted on November 13, 2012 at 21:20 Hello, i am working on project where i need to save array stored in stm32 to sdcard problem is i was able to make it work using project, but somehow i was unable to crate new file. Idea that i press b...
Posted on November 12, 2012 at 22:53I love the StdPeriphDriver files (inc, src) for all the discovery products. I recently received a Keil MCBSTM32F400 evaluation board that uses a ST32F4407IG. Question is can I port the StdPerhipDrivers from F4 D...
Posted on November 12, 2012 at 20:58The following is my watchdog code. The watchdog is triggering and I am constantly find myself in the startup routine. Why? Here is my watchdog related code: //After Periph Clock set and before GPIO and NVIC set...
Posted on November 13, 2012 at 13:11Hi all Can higher priority interrupt interrupts lower priority in his execution? For example. When I am servicing DMA ISR routine with priority 0x01 and EXTI interruption with priority 0x00 if and only if happens....
Posted on November 13, 2012 at 18:46Hi. My name is Steve. I have some microcontroller experience with AVR, Stickos and Arduino and have recently bought an STM32F4 discovery kit as I am interested in its DAC , DSP and audio capabiiteies. I have some ...
Posted on November 13, 2012 at 11:33I was planning on using an STM32F103RE in a design where the DACs would be part of a control loop, and will need to be used in 12 bit mode. Unfortunately the DAC specifications in the datasheet show extremely bad...
Posted on November 08, 2012 at 15:23Evaluating the STM32F207 for a project. I need to create a triangle waveform, starting from an arbitrary point between two limits, and it needs to be able to start in both incrementing or decrementing fashion. I i...
Posted on November 04, 2012 at 10:25Hello, I am experiencing some troubles recently with floating point calculation within interrupts. I have a dma interrupt running at 400 Khz in double buffer mode. I have an usart RX interrupt coming at 50 Hz. the...
Posted on November 08, 2012 at 15:51I see that there are dedicated forums for some of the STM32 Discovery boards, such as the Discovery-F4. Will there be a dedicated forum for the Discovery-F3? The dedicated forums are a little hard to find because ...
Posted on June 06, 2012 at 15:59Hi,I'm working on a custom design with in a STM32F4xx. A 420mF capacitor is connected to Vbat. ( with a serial diode and a resistor between Valim and Vbat to charge up the supercapacitor ).The system power off it stil...
