New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...



Posted on September 26, 2012 at 18:20Hello!I'm trying to get an STM32F407 with the LQFP176 Pinout to output in OC PWM1 mode.  My code is as follows:  /* set up GPIO as timer output GPIOI 5, TIM 8 CH 1*/    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOI...

IIR functions in DSP libraries (STM32F407xx)

Posted on September 28, 2012 at 19:08Dear colleagues,          are there any stable libraries for IIR (recursive) filters for the STM32F4x, aside of the CMSIS DSP software library? The CMSIS has only lattice (arm_iir_lattice***) or biquad (arm_biqua...
