Sysblocks has four analogue inputs, two analogue outputs and support circuitry. The 32 bit PICmicro microcontroller is programmed by a host device which is a
standard 18 series PICmicro microcontroller. This host device takes care of non-core tasks like USB communications, LCD display, encoder and switch inputs.
This architecture keeps the main 32bit device free for signal processing.
Two E-blocks ports are made available for expansion. E-block boards for Wifi, keypad, Bluetooth, CAN, Zigbee and many other functions are available, along with
a Grove connector, giving huge flexibility. The analogue input signals are buffered and level shifted to half of the supply voltage – 1.65V – and then fed to
the internal A to D converters of the main 32 bit PICmicro microcontroller.
A digital potentiometer allows the level of the input signals to be adjusted in software. The board is fitted with a number of switches and encoders for control
purposes. The board also has a miniature monochrome graphical display and a number of programmable LEDs including 2 x 8 LED VU meter LEDs. The board is powered
from 3.3V from USB or from a plug top power supply.
