Posted on September 24, 2013 at 11:40I had read that STM32Fx series has adc self calibration feature but I couldn't find any register/explanation in reference manual of STM32F205.Also is it possible to assign different sampling time in SMPRQ registe...
Posted on September 24, 2013 at 03:21I have a project that has a mix of cpp and c files. The symptom is that at certain times, the code gets stuck at the end of the startup_stm32f40xx.s at the ''B'' line.DCMI_IRQHandler ...
Posted on September 23, 2013 at 11:19 Hi, I am trying to establish I2C communication between STM32F4 and OV5642 Camera module( http://www.arducam.com/camera-modules/5mp-ov5642/) and I want to test it separately. I already worked with I2C a...
Posted on September 16, 2013 at 15:30I've pruchased a STM32439I-EVAL2 (5,7'' TFT) module for evaluation, the manual state demo software may be downloaded from http://www.st.com but I've been unable to find it. Also, is there a stemWin version compa...

Posted on September 23, 2013 at 08:42I�ve have a problem with the ADCs in dual regular simultaneous mode. I want to measure 3 channels with ADC1 and 3 channels with ADC2. The conversions are started by software. I want to get 32 acquisitions in DMA ...
Posted on January 22, 2012 at 23:30Hi, I am just trying to fully customize the USB CDC example / Virtual comport. I changed the USBD_PRODUCT... string and USBD_MANUFACTURER_STRING in usbd_desc.c. I also copied STMCDC.INF to a TEST.INF, and in the TE...
Posted on September 23, 2013 at 14:34 Hello! I want to get defined number of samples at constant sample rate. I used ADC1 triggered by TIM15 TRGO signal and DMA in normal (not circular) mode with interrupt on transfer complete. Something is wro...
Posted on September 22, 2013 at 22:46Hi, i use a STM32f3discovery evaluation board and trying to generate 6 PWM signals. For this purpose i have choosen Timers 3 and 4. As base project i use a Demo project. (The project demonstrates a sensors func...
Posted on September 22, 2013 at 20:50I am currently reading a high speed ADC over SPI1. E11 is configured to generate a DMA SPI write/read when the busy signal from the ADC goes low. A double buffered DMA moves the data from SPI to memory. Works ...
