Posted on August 17, 2014 at 02:04Hi, I have a device which is sending an inverted UART on the line. The startbit is 1, the stopbits are 0. The whole line is inverted, but the other syntax of uart is right. So is there e possibility for receiving th...
Posted on August 16, 2014 at 22:34I'm trying to find an example of loading the next timer delay via DMA. I want to sweep a square wave over a range of frequencies and this looks as if it might be able to do it very neatly. Assembly preferred as I'm...
Posted on August 16, 2014 at 19:00Hi guys.I have a STM32F4 Discovery Board. I had some programs for it, it was work very good.But Now STLink V2 debugger on board not working.My computer has not detected to board. Both of Leds are not blinking.Whats ...
Posted on August 16, 2014 at 18:52 Hi, my experience with serial comunication is very poor, after six months of ''pain'' trying to implement some AHRS algorithms, now i want to port that data to matlab for example, but i need every dataset t...
Posted on August 10, 2014 at 20:58Hi all, I am planning on using the STM32F439 as I need as much performance as possible. As I understand it, to upload a program to the board I will need the ST-Link V2. Could someone please explain how I would conne...
Posted on August 15, 2014 at 02:03 I know for a fact that this question has been asked before (I've seen it) but for the life of me I cannot find it, so I appologize. I am unable to get some of my EXTI interrupts to clear their pending st...
Posted on August 15, 2014 at 15:57I am using a STM32L series MCU. I am trying to trigger ADC at 16KHz with a TIM3 and later use DMA to store the ADC values in a buffer. The issue is that I am trying to test the ADC rate using a GPIO_Toggle in the AD...
Posted on August 15, 2014 at 12:09Hello everybody.I am having trouble writing data to the STM32F0 flash. I would like to store a look-up-table in a page of flash. My intention is to flash this in during production, so I have added it to the appropri...
Posted on August 15, 2014 at 13:15Hey guys, I work on my bachelor thesis with an stm32f4 discovery board. I want to revive data via UART3 form PC. The Data fit at the Rx Pin (GPIOC.11), i checked it with the Oscilloscope. But de controller doesn’t j...
Posted on August 14, 2014 at 13:53Hi!ST refers to a technology called muxed PSRAM.As far as I know, this simply means, that the data and address signals share the same IO pins.All simple and good, but my question is, could someone point me to a PSRA...
