Posted on May 22, 2015 at 11:17I am using a STM32L152RC microcontroller and have to detect the length of pulses of about 0.7 V and 3 ?s using the COMP2 comparator. At 2.7 V VCC the worst case propagation delay is 2 ?s in fast mode. A minimum delay i...
Posted on May 24, 2015 at 19:17 Hi Guys, I am very new to the STM32 family and right now I am using a STM32F100 to be able to generate a PWM with TIM1. The end goal is to generate a PWM that can be filtered to show a sinewave so I need v...
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 21:42I am designing an USB device on the STM32L151CB micro-controller. I use the STM32Cube_FW_L1_V1.2.0 USB library. My device enumerates correctly. I reach the point of sending an receiving data. I implemented a class laye...
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 22:22Is there a way of acessing Tim2 3 4... CC interrupts since they are not declared?Or do I have to access them by TIMx_IRQHandler? Thanks
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...
