4.5 Task 5: Use of the Debug Interface

4.5.1 Introduction

4.5.2 Setting up the code

32185A-AVR-01/12
The parameters are as follows:
•
sensor_type
•
from_channel
•
to_channel
•
aks_group
•
detect_threshold
•
detect_hysteresis
•
position_resolution the resolution of the reported position value
•
position_hysteresis the hysteresis of the reported position value
•
p_sensor_id
The range of
position_hysteresis
The debug interface is used to communicate various touch sensor information to the
computer running Atmel QTouch Studio. The debug interface as seen from the Atmel
AT32UC3L is implemented completely in firmware. This is to be added only for
debugging purposes.
Add the source files.
• QDebug.c
• QDebugTransport.c
• SPI_Master.c
These source files with the corresponding header files are present in Task 5 folder.
1. ,
QDebug.c QDebugTransport.c
headers can also be found in the qebug folder.
2. The debug interface is used to communicate various touch sensor information to
a computer running Atmel QTouch Studio.
3. In the solution explorer tab in Atmel AVR Studio, right click the project and select
Add Existing File, and then select the above mentioned source files and the
corresponding header files from Task 5 folder. Alternatively, you can drag and
drop the file onto the project. Similarly include the other source files.
4. The Atmel QT600 interface board and QTouch Studio can be used to read touch
data from any application based on the
USART SPI mode as the communication interface.
5. Open the Project properties Window, select tool chain tab and click on Directories
option below AVR/GNU C compiler, and specify the right paths for all three files
(enter the relative path). Make sure those directories paths are included both in
Release and Debug profile.
