diode.
The 5 V output from the SBC is routed to the microcontroller board via jumper J7, where
it supplies the main MCU.
The SPI signals are routed directly between SBC and main MCU via header J4 and its
counterpart J2.
The RSTN signal on the SBC is connected to the reset input on the main MCU via
0 Ω bridge R11. When terminals 2 and 3 of header J104 are connected with a jumper,
pushbutton SW5 on the MCU board allows the RSTN signal to be pulled LOW manually.
This function could be used, for example, when restoring the MTPNV register factory
preset values.
The USB MCU is powered via the USB interface. The signals between main MCU and
USB MCU are passed through level shifters that serve as a bridge between the two
supply domains.
Double-click on file flexgui-app-ivn-uja116x-1.0.0.exe to begin the installation. The
FlexGUI application starts automatically after a successful installation.
FlexGUI can be started via the Windows Start menu or the shortcut symbol on the
desktop
