B.2. Conﬁgure OTG/CFast

Both VS-860 and Alekto2 use USB OTG port in two modes: OTG and CFast. The mode can be

switched both via jumper and GPIO pin (software). The software settings “overwrite” the jumper.

Executing onrisctool.py will show the status of hardware/software settings. Following output

says, that the USB port is in OTG mode set over jumper:

OTG automatic mode: OTG

You can switch to CFast via executing:

onrisctool.py -o cfast

If you then execute onrisctool.py without parameter you’ll see following output, indicating, that

CFast mode is set via software:

OTG force mode: CFast

B.3. Conﬁgure RTC

onrisctool.py lets you read the RTC directly and also write current system time to it.

Reading RTC:

onrisctool.py --readrtc

RTC read: 2013-06-03 12:44:47

Writing system time to RTC:

onrisctool.py --systohc

B.4. Conﬁguring Digital I/O

As described in Section 6.1.2 Alekto2 provides 8 digital I/O pins. With onrisctool.py you can

set direction and data.

Set direction “output” for the ﬁrst group:

onrisctool.py -c out -g 0

Set pin 0 to 1:

onrisctool.py -m 0x01 -d 0x01

Set pin 0 to 0 and pin 1 to 1:

onrisctool.py -m 0x03 -d 0x02
