Posted on May 24, 2015 at 16:24HelloFor some purpose i need to run DCMI interface with maximum frequency(it is 54MHz, right?), i provided pixclk pin with 56MHz clock(sysclock divided by 3 coming out of mco2 pin) but it seems that overrun occurs on D...
Posted on May 24, 2015 at 22:22Hi, I've been trying to use the SD_B output on an STM32F427VIT6 with no success. This is the 100 pin package. With typical SAI usage, SAI block B would not be usable since the MCLK, SCLK, and FS pins are on port F, w...
Posted on May 24, 2015 at 00:50I am new to STM32F030. I am going to use PWMs as the dimming input of LED driver. I have checked DM00088500.pdf, DM00091010.pdf and DM00051352.pdf already. But I still not able to indentify which pins are the output o...
Posted on September 10, 2013 at 12:08Hi guys, I'm having a few issues setting of a DMA transfer based on a timer and hoping someone might be able to point out where I'm going wrong. I have a timer (timer 2) which is set to 50 Hz and as far as I can ...
Posted on May 23, 2015 at 15:42Hello: I have the 429I Discovery and can't get the serial <-> USB through stlink to work as it does on all the nucleo boards -- is this functional? I have updated the stlink firmware, added a connector to the TX/RX pi...
Posted on May 21, 2015 at 22:20We are using the STM32F429ZIT6 and we need to keep the RTC running when VDD is not present. Can we hook up a coin-cell battery directly to VBAT, with no switching/monitoring circuit? Any help would be MUCH appreciate...
Posted on May 12, 2015 at 07:56 Hello everyone, I need to measure sleep time of my Cortex-M4 processor (STM32F4xx). I looked at DWT where I also use normal tick counter and I enabled SLEEPCNT counter. However, I noticed that it is 8-bit ...

Posted on March 04, 2014 at 11:32I had a quick glance into the new format ST libs that come with STM32cube. We have some projects using the Std peripheral libs and wonder if they should be refurbished to be used with the new HAL libs. I'm a little c...
Posted on September 24, 2014 at 19:01[duplicated thread due to locked thread above] Impressive, looking forward to real silicon. Nice: - all clocks apper to be able to tick up to 200MHz - low-power timer running independently of the main clock (i.e....
