Title: Feature adc lowfreq

ADC sampling speed is higher than necessary. Current necessary to charge sampling capacitor is causing error for high-impedance sources - typically current measurement.

This patch triggers ADC conversion from systick handler, decreasing conversion to 1kHz. At this speed sampling current is much smaller that other error sources. Only stm32f10x is changed - 30x conversion speed is lower than 1kHz
