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...
Posted on November 08, 2012 at 16:52can't install drivers under windows 8, the ''unsigned driver '' error appears. workarounds with reboot to troubleshoot menu does not work because there is no such menu in full version (not dev. preview). is there ...
Posted on November 12, 2012 at 18:47Greetings - Seek the higher performance (faster downloads) achievable w/J-Link ''SWD'' rather than the ''on-board'' ST-Link. Reviewed the F4 Discovery schematic - does not appear that there is any easy way to ''b...
