Posted on March 17, 2013 at 15:31Hi I'm just wondering why the LSI on the STM32F4 Discovery board has inaccuracy's, I've searched the internet and application notes but can't seem to find the answer? My seconds on LCD jumps several times between 0-6...
Posted on March 17, 2013 at 17:37I'm working on a project where power consumption is a critical issue. I need to store a frame from a camera (OV2640) on the uSD each 2 seconds. My problem is that the camera's clock is always on which bring the power...
Posted on March 09, 2013 at 14:29Hello, I am trying to generate sinusoid signal via DAC. I can´t use look up table of sine values, because user will enter amplitude. So values of sine are first computed in program and than stored in buffer: sine[i...
Posted on March 16, 2013 at 21:38Hello, I want to implement the bipolar 4-quadrant complementary switching using STM32F103C8 TIMER1. The bipolar switching requires that the top and bottom switch PWM signals need to be swapped.I have read STM32F103C...
Posted on March 09, 2013 at 17:28 Hello peolpes, maybe somebody can help me. For a testing I use two I2S - one(I2S3) for transmitting, second (I2S2) - for receiving, phisicaly connected at the PCB. At both I use Double Buffer DMA...
