Posted on October 22, 2013 at 02:09In the STM32F205 datasheet, it says that in STOP power mode, all clocks on the 1.2V power domain are stopped. Is there anywhere I can look to see which clocks are part of the ''1.2V power domain'' ? Particularly, I...
Posted on October 21, 2013 at 20:07 I've DMA1 stream 3 channel 0 configured to handle the I2S2 data coming in from my UDA1380 codec and what I notice is that when configuring the Memory0BaseAddr to be the beginning of my circular buffer, the con...
Posted on October 20, 2013 at 19:17 hello dear forum, I am trying to read an AB encoder with stm32f4 timer_1 I got the encoder signals through 75175 to timer_1_ch1 and ch2 pins I can see square waves of A and B with osciloscope ...
Posted on October 20, 2013 at 04:11Hi all,I'm at my wit's end with this little project I'm working on. I'm new to MCUs and had a few ideas on small projects that I would like to make. I've been following a guide on the STM32 and modifying bits and p...

Posted on October 21, 2013 at 16:10Hello,I am using a : STM32F303RC (256k FLASK, 32k RAM, 8K CCRAM) gcc g++ tool chain with Eclipse. At compilation time, my firmware memory are as following:arm-none-eabi-size --format=berkeley -t Muster.elf text ...
Posted on October 21, 2013 at 10:26 Hello again, I have learned that this: void DMA2_Stream3_IRQHandler() { // Test if DMA Stream Transfer Complete interrupt if (DMA_GetITStatus(DMA2_Stream3, DMA_IT_TCIF3)) { DMA_ClearITPend...
Posted on June 08, 2013 at 12:03I am using stm32f103rbt6 for frequency capturing. I am trying to use timer1 channel1 and channel2 to capture two different frequency say 1K and 500 hertz. Once 1k frequency rising edge is detected i am reading the CCM...
Posted on October 18, 2013 at 22:41Trying to stuff multiple channels of ADC3 into a DMA, but am unsure of how the DMA address gets incremented. Is this done automatically behind the scenes and I don't have to worry, or am I missing a setup? I didn'...
Posted on October 17, 2013 at 10:03I have about 2 - 3 channels which I need to sample differently , as in, say: ch1 : at 400 Hz, batch processing samples at 100, (possibly one more chan like that) ch2, 3: one sample every 100 is ok. The ADC sampl...
