Posted on May 25, 2015 at 14:26We have a solution, which reading audio file from SDCard and playing by I2S. It works ok when the CPU Clock Speed is >= 84Mhz. To reducing the Power Consumption, we have to reducing the CPU Clock Speed to 24MHz, then t...
Posted on March 18, 2014 at 03:12Hello, I am planning on using the SDADC in STM32F37x microcontroller. The data sheets says the sampling frequency is between 500 kHz ~ 6 MHz, depending on the clock signal driving the SDADC. The output data rate is...

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 ...
