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...


for an inverter PWM -ADC -feedback -synching

What is the best meathd to of feedback method In sineinverter (like commercial) ?is it good by a forumal appling instead using look up rable .It saves the memoryIf i use look up tableconst unsigned char sin_table[416]={0, 16, 32, 47, 62, 77, 91, 103,...

2 channel PWM with 90 degree phase shift it possible to create such a two channel pwm with any timer?(in output compare mode the falling edge of the first channel overlaps on rising edge of the second channel overlaps, but its not good for my purpose) thanks.

ADC Readings Lower than Ideal

I am using an STM32L562VET6Q MCU.  I have been having issues getting a valid reading from the ADC.  The signal is essentially DC (i.e., no fast high frequency measurements) so I conservatively set the ADC sampling time to its maximum.  My reference v...
