Posted on January 17, 2014 at 08:59 hi I am writing a simple code for converting float point number to the string , but this code just without enabling the FPU . if FPU was enabled , this code doesn’t work. I am working with KEIL compiler. ...
Posted on June 19, 2013 at 16:16Hello, I am facing a problem with the timers I am using in STM32f100 MCU. I have configured different timers to operate during the execution of the code, but somehow, all the flags related to Capture/compare or Update...
Posted on January 19, 2014 at 00:26 I am using stm32f103 to transmit some data over SPI while stm32 acts as slave. I need to use DMA for sending data to the SPI but the corresponding interrupt handler is never called. The code comes in the follow...
Posted on January 19, 2014 at 07:54I am trying to figure out the default clock speeds (after reset) for the buses and the peripherals and system clock for the STM32107VC. I am reading the STM32107 Reference Manual RM0008 on page 123.One thing I do n...
Posted on January 18, 2014 at 21:28Hello,My project is to drive some SPI external sensor with 3.3V and read its data. Since this sensor consumes a higher current that a single I/O can supply I intend to drive this sensor using 3.7V battery.As noted ...
Posted on January 18, 2014 at 20:49 Hello, first I am sorry if I didn't need to open new thread. I searched through lot of examples in this forum, about EXTI. And most of them were similar to my problem, but non of them helped. :(<br>I am using ...
Posted on January 12, 2014 at 07:43 Hi, I just received my STM32F429 discovery board and I tried to implement basic SPI but I'm stumped as to why the logic analyzer output was different. Can anybody point out were I was wrong. Here is the code. ...
Posted on January 17, 2014 at 18:09In order to test the Hard Fault interrupt, I modified the Systick example on ''STM32F0xx_Discovery_FW_V1.0.0'' as follows.. on main.c I added two lines: ------------------------------ int main(void) { uint8_t* Byte...
Posted on January 09, 2014 at 02:46I wrote a library for the STM32F4 Discovery kit. The name of this library is ZIOS.ZIOS includes low level functions. You don't need to MCU registers access for your application programs. Also I wrote simple demo pr...
Posted on January 15, 2014 at 20:51Hi I am trying to understand how to interface incremental encoders to stm32f407 ( 2 encoders) : my problems : Which pins can I connect to it; should I connect to the pins directly ? . How can I did detect the ...
