(Only One Cable Project)
You think they are too many cables on your devlight ?
yes me too :
Yes it is possible to develop applications with only one cable :
To program the apf, we need tree cables to
- Power the kit (AC/DC bloc)
- control the system (RS232)
- download files fastly (Ethernet)
But it is possible to use only USB to :
Power the kit
USB protocol can provide up to 500mA (100mA by default) at 5V, then we have to plug usb power on dev light power and usb-gnd on devlight gnd like this :
control the system : tty console can be emulate over USB
In the first time, RS232 is needed to configure the kit. Here is an explanation how to configure module g_serial to use USB as serial port.
To launch on boot, I wrote a script named S10gserial in /etc/init.d/ directory
#!/bin/sh modprobe g_serial
download files fast
with USB tty console can be more fast than standard RS232 then, big files can transit trough it.
