ARM7 Processor Peripheral Sample Demos

Location

$TwlSDK/build/demos/spi
$TwlSDK/build/demos.TWL/spi

Compilation

Move to the $TwlSDK/build/demos/spi (or $TwlSDK/build/demos.TWL/spi) directory and enter the following.

% make

  The compilation begin, and the SRL executable file and the NEF or TEF files with binary information are generated in $TwlSDK/build/demos/fs/(sample name)/bin/(platform)/(target)/.

$TwlSDK/build/demos/spi/(sample name)/bin/(platform)/(target)/
$TwlSDK/build/demos.TWL/spi/(sample name)/bin/(platform)/(target)/

 For example:

$TwlSDK/build/demos/spi/tp-1/bin/ARM9-TS/Release/main.srl

is the executable file for the tp-1 demo.

Execution

If using the Ensata emulator:

If using IS-NITRO-DEBUGGER:

If using IS-TWL-DEBUGGER:

For TWL/NITRO Hybrid ROMs

If using IS-NITRO-DEBUGGER:

If using IS-TWL-DEBUGGER:

For TWL Limited ROMs

If using IS-TWL-DEBUGGER:

Description


Name Directory Operation
tp-1 demos Displays touch panel input positions on the screen.
tp-2 demos Displays the track of touch panel input positions on the screen.
mic-1 demos Displays the microphone voice input status on the screen as a waveform.
mic-2 demos Displays microphone voice input status on the screen as a waveform, and outputs text data.
The mic2wav.exe tool can convert the obtained data into a WAV file.
mic-3 demos.TWL Displays a waveform on the screen indicating the state of audio input, based on the TWL's own microphone auto-sampling methods.
mic-4 demos.TWL Displays a waveform on the screen indicating the audio input status, based on the TWL's own microphone auto-sampling methods, and outputs it as text data.

The mic2wav.exe tool can convert the obtained data into a WAV file.
spiMonkey demos Displays touch screen and microphone input status on the screen while playing the background music.
spiMonkey2 demos Displays touch screen and microphone input status on the screen while playing BGM.
Unlike spiMonkey, it uses automatic sampling to sample the microphone.
spiMonkey3 demos.TWL Displays touch screen and microphone input status on the screen while playing BGM.
Unlike spiMonkey2, it uses the TWL's own auto-sampling method to sample the microphone.
pm-1 demos Enters sleep mode or power save mode by pressing the power button or closing the cover.
pm-2 demos.TWL When the power button is pressed, the system will wait for the user operation to actually exit the application.
pmAmpGain demos Manipulates the gain of the audio input through the microphone.
The results of sampling the audio input are displayed on the screen as a waveform, much like with the mic-1 demo.
pmAmpGainLevel demos.TWL Manipulates the gain of the audio input through the microphone.
Unlike pmAmpGain, this demo can manipulate the gain with a finer resolution thanks to the TWL's unique features.

Operation

mic-1, mic-2, spiMonkey, spiMonkey2, and pm-1 do not function properly with ensata.
mic-1 and mic-2 function normally only when using NITRO ROM.
tp-1, tp-2, spiMonkey, and spiMonkey2 attempt to read touch panel calibration values from the non-volatile memory (NVRAM) in the DS. If they do not succeed they will terminate with an exception. In this case, use the DS Start menu that is built into the Nintendo DS to store calibration results in NVRAM.
