Touch on Atmel SAMD20/21 and QT6 Xplained Board
A touchpad solution on Atmel SAMD20/21 and QT6 Xplained board based on ASF(Atmel Software Framework) and QTouch Surface Library.
- The Atmel SAM D20/D21 Xplained Pro evaluation kit is ideal for evaluating and prototyping with the Atmel SAM D20/D21 ARM Cortex-M0+ based microcontrollers.
- The QT6 Xplained Pro is a QTouch Surface extension board for Xplained Pro boards that demonstrates the Peripheral Touch Controller (PTC) as a high performance touch-surface controller.
- The Atmel Software Framework (ASF) is a MCU software library providing a large collection of embedded software for Atmel flash MCUs: megaAVR, AVR XMEGA, AVR UC3 and SAM devices.
- Atmel QTouch Surface Library makes it simple for developers to embed capacitive-touch surface functionality into general-purpose Atmel SAM D20/D21 microcontroller applications.
How to Build
Build with
arm-none-eabi-toolchain in Cygwin/Linux/MacOS.
Build in App Dir
$ cd project_root_dir
$ source envsetup.sh (*MUST*, one time shot)
$ cd apps/hmc
$ make clean
$ make
- or -
$ make -f Makefile
Build App from Top
$ cd project_root_dir
$ source envsetup.sh (*MUST*, one time shot)
$ mmm apps/hmc
Usage:
mmm [path] [option]
- path - relative path to Makefile (for an App) to be built with
- option - target to make, eg clean, debug, release, etc
Example:
mmm apps/hmc clean (* at top folder)
mmm apps/hmc (* at top folder)
mmm . clean (* at apps/hmc)
mmm (* at apps/hmc)
How to Flash Image
Flash by Path From Top
$ cd project_root_dir
$ ./fam.sh [path] [action]
Usage:
fam.sh [path] [option]
* path:
- App path, relative path to exe/xxx.bin in unix format,
eg, MUA/main (exe not included in path)
* option:
- E - erase
- P - program (default)
- R - read
- EP
Example:
$ ./fam.sh apps/hmc
$ ./fam.sh apps/hmc EP
$ ./fam.sh . E
$ ./fam.sh
$ ./fam.sh . P
Flash Script Wrapper
$ cd project_root_dir
$ source envsetup.sh
$ fa [path] [action]
-or-
$ cd <path_to_app>
$ fa
fa is a wrapper of fam.sh, it use the same parameters and can be used anywhere which have exe/xxx.bin in the folder without parameters.
edbg Usage
Usage: edbg [options]
Options:
-h, --help print this help message and exit
-b, --verbose print verbose messages
-e, --erase perform a chip erase before programming
-p, --program program the chip
-v, --verify verify memory
-k, --lock lock the chip (set security bit)
-r, --read read the whole content of the chip flash
-f, --file <file> binary file to be programmed or verified
-t, --target <name> specify a target type (use '-t list' for a list of supported target types)
-l, --list list all available debuggers
-s, --serial <number> use a debugger with a specified serial number
-o, --offset <number> offset for the operation
-z, --size <number> size for the operation
Example
$ edbg -bpv -t atmel_cm0p -f apps/hmc/samd_qtouch_mutlcap_example_flash.bin
Debugger: ATMEL EDBG CMSIS-DAP ATML2407060200000332 02.01.0157 (S)
Target type: Cortex-M0+
Target: SAM D21J18
Programming....... done.
