2.3. Display modification to control illumination
In case of you are using the backlit LCD you have to make the changes as shown. Use the
component R5 or R6 (0 ohm resistor) to put it on the position of R7.
The change is not required you just can control the illumination.
1. Remove R5 / R6 2. Place R7
Hint: The changes requiring average soldering skills with SMT components!
Do some soldering test before, if you doesn’t feel well enough with such changes.
It is important to use a soldering iron with a slim tip.
3.0 C++ Language software package for Asuro xTend
The C++ language is a superset of the C language or vice versa the C++ language is an
extension of the C-language, but more powerful and structured more rigid in the compiler
checks.
All in all it gives a better readable code and better protection against side effects of your software
design (e.g. enums and the use of name space definitions for the modules instead of tons of
#defines) - and of course with C++ you can combine C-code and Assembler-code if required.
Special advantages, will be given if you have multiple instances of e.g. a device driver like a
UART which saves memory. The developed code is also easier to port to a new system.
The used Extended Embedded C++ excluded by purpose the following C++ features, which
doesn’t make sense on an embedded system:
- RTTI
- Exceptions

The make file to support your existing C- code and the code Libs from the Asuro board and the
C++ code from the Sensor & IO board with examples are included.
