Posted on January 24, 2012 at 08:48Hi, I am using STM32F207xx for my application. In my Application,I am using OTG_FS ,FSMC & DMA for TFT Driving. If i Disable all other interrupts except for USB_FS,then USB works fine. But if all other interrupts(...
Posted on January 23, 2012 at 18:50I have an STM32F4 Discovery board; recently I just had uploaded some code pertaining to the PWM example where I made PD12-15 some PWM signal so I could see it working with the LEDs on board. The program uploaded an...
Posted on January 22, 2012 at 21:00I'd like to see some sample code (or a link to it) that utilizes a timer fed by an external clock, not the system clock, to generate an output pulse. All ST's sample code that I've seen so far uses the system cloc...
Posted on January 23, 2012 at 03:24Hi all,I am trying to use the arm_cortexM4lf_math.lib in one of my projects, but the linker cannot find it. I have tried just about everything (setting library / library paths etc), but I am a bit new to ST/ARM/Ato...
Posted on January 20, 2012 at 04:54I've seen figures quoting speeds of over 7.2 MSample/sec, when using triple ADC a 36MHz ADClock, and DMA. However, at those speeds (by my calculations) the effect of RADC on the input sample circuit means you lose ...
Posted on January 23, 2012 at 11:42Hi there, I am implementing a emulated EEPROM in flash memory on a STM32 microprocessor, mostly based on the Application Note by ST (AN2594 - EEPROM emulation in STM32F10x microcontrollers). The basics outline the...
Posted on January 08, 2012 at 00:00Hello, I'm starting developping, a USB composite device, can you please give some rules, guidlines, software example, in order to get starting with such application, Thanks for your help gafsos
Posted on January 23, 2012 at 11:59Hi all, I created a simple circuit connecting a STM32L151C6T6 to a LSM303DLHC accelerometer. They communicate using I2C interface. I made the first simple test program modifying I2C EEPROM example included in STM32...
Posted on January 23, 2012 at 08:41Hi, I'm using audio example from std_periph_lib on my STM32, and I've got a reccurent error with I2C. The example print on screen ''CODEC I2C ERROR'' but not always, sometimes it works ! If someone know what is th...
Posted on January 19, 2012 at 22:57Hi,I'd like to transfer less than a full block of data (i.e. less than 512 bytes) from the SDIO FIFO to another peripheral that's mapped into an FSMC address directly using DMA without having to first transfer the ...
