Posted on July 13, 2012 at 10:56Dear ladies and gentlemen, I am currently writing on my Bachelor thesis about boundary scan and its advantages/ disadvantages. Our company is currently launching the new STM32 micro-controller family and it is my task...
Posted on July 03, 2012 at 13:44Hi, As you can see from the schematic below,the ''C3'' capacitor is a low voltage 1.5F supercap that I use as backup battery to keep the mcu up during the stand-by mode. My problem is that,while I flash the program me...
Posted on July 12, 2012 at 16:08 Hi, Hardware -> STM32-Discovery IDE-> Keil uVision getBit(USART2->SR, position) works in the non-interrupt mode, but, it doesn't in the USARTn interrupt mode...! I have linked the USART1's...
Posted on July 12, 2012 at 02:23Using stm32f4 discoveryI am off to a good start with this board. I can not do floating point numbers. That is annoying but ok. I decided to move on and not use floating point numbers. When I try to fixed point I don't...
Posted on July 12, 2012 at 12:53i have connected the usb hub to the discovery board using micro usb port...now i connected a pen drive 1 to the one port on hub...i want to do is when i connect another pen drive to the 2nd port on hub...the ucontroll...
Posted on July 12, 2012 at 18:32I'm wondering if it's possible to generate a clock (or 1PPS) on the MCO pin? I'm just not sure how far down you can divide this clock... If this isn't feasible, is it possible to generate a 1PPS with the RTC?
Posted on July 11, 2012 at 14:52hi alli need to know that is DMA uses the SRAM as the DMA buffer??????if yes then my MCUstm32F407 got 112Kb and 16Kb of SRAM.and DMA max buffer size is 64kb, in the case DMA is using half of my SRAM,is there a possibi...
Posted on July 11, 2012 at 13:55Hello ,I am new to STM32. I am reading data from USART using DMA. I dont know how to directly access data from DMA memory after transfer complete interrupt.
Posted on July 11, 2012 at 16:59Hello, in the Document RM0008 (datasheet of the STM32F10xx Family) on Page 510 is the FSMC access described with the external WAIT Signal. It works well for my application now, but i have some problems by understandi...
Posted on July 11, 2012 at 16:36Hi all, I have a simple routine called in TIMER_IRQ event that set GPIO and than set a DAC on SPI BUS. This routine must be quick as possible. Regarding the GPIO setting there is no particular problem, while SPI has s...
