SOLO BETA User Manual
Digital Control using USB or UART protocol :
One of the ways of commanding and getting feedbacks from SOLO in a complete digital mode is
using the USB or UART communication protocols, the USB is accessible through a micro USB type
B connector mounted on SOLO and UART is accessible through the “Communication Port
” of SOLO
as can be seen below, by using any of these two an in digital mode, you can fully control SOLO in a
complete digital fashion with all the commands and feedbacks sent and received through data
packets without the need to send any forms of analog commands like PWMs and so on.
As can be seen, in the communication port, Pins 17 and 19 are in the TX and RX pins of UART respectively
and they support 3.3V level signals. Please notice that these pins are NOT 5 volts tolerant and in case you
want to send/receive signals in 5V range you need to use a level shifter module or IC, in which they will shift
the 5V level into 3.3V level suitable for SOLO, in case of connection of 5V to these pins, the permanent
damage to the board in imminent.
The main settings for UART or USB communication between SOLO and the secondary Modules/PC should
be as following:
UART or USB hardware settings:
The proper hardware settings to communicate with SOLO are mentioned in table below:
- * SOLO can be commanded in both of these baud-rates, the standard baud-rate is used
when the external system supports only standard baud-rates, but for those systems in
which the baud-rate can be set manually, it’s better to use the exact baud-rate value due to
higher accuracy of data transmission.
