Posted on August 09, 2014 at 06:51Hi there! I'm using my stm32f4 timer 5 in encoder interface mode. In reference manual it is written for CCxNP/CCxP pins that they should not written 11 (i.e. polarity of trigger on both edges) in encoder interface m...
Posted on August 08, 2014 at 07:49Hello, I am generating a sine wave by DDS method, but I dont know why the signal is flattering at the bottom. Does anyone have any idea why is this happening. Thanks #stm32 #dac
Posted on August 08, 2014 at 17:29ADC resolution 12 bits(with 16 bit buffer) works but 8 bit(with 8bit buffer) results in the code going into an infinite loop in the DMA ISR. __IO uint8_t buffer[1000];/* ADC Config*/ ADC_StructInit(&ADC_InitStructu...
Posted on August 08, 2014 at 19:27Hi:I am using a STM3221G-EVAL board from ST. Attached is the IAR project I downloaded from the STM32CubeF2 folder that examples the GPIO.The example uses 2 Pushbuttons, KEY and WAKEUP to turn ON 2 LEDs on the board....
Posted on August 08, 2014 at 15:07After reading through the promotional material, datasheet and reference manual for the STM32F3's SDADC and spending a few days trying to obtain a 16KHz sampling rate, I believe some clarification of the limitations ...
Posted on August 06, 2014 at 11:49Hello there!I've interfaced 128 MB(16 bit data bus) sdram through fmc interface in my stm32f429 device. Initialization and everything seems ok. Reading/writing to sdram is ok for small chunks. But writing 12 MB or l...
