STM32F407 MEM2MEM dma TRIGGER

Posted on May 24, 2015 at 13:36Hi to all i want to trigger DMA on MEM2MEM State and use it by fsmc to run an External 12 bit DAC(AD5445) in 50ns Step. is there any way to do that without using interrupt? #dma #memory #fsmc #timer-trigger #mem2mem...

STM32F373 SDADC (Sigma-Delta ADC)

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...

HSE oscillator power consumption

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...

Comparator rising/falling edge propagation delay

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...

STM32F100(RBT6): PWM generation with TIM1

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...

problem using SAI block B on STM32F427VIT6 (100 pin LQFP)

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...
