Posted on May 22, 2015 at 12:25Hello,I estimate the total power consumption of a device operating from the HSE oscillator. The MCU part number is STM32L152RBT6.I configured the MCU to operate from the MSI oscillator (2.1 MHz). All the GPIO are confi...
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 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...
