If you're not familiar with Daytripper yet, please see the Quick Start Guide first.
Instead of hiding windows, you can perform custom actions when TX is triggered.
Slide the Mode Select Switch on RX to CUSTOM, middle position. Now ALT + PAUSE will be pressed when TX is triggered.
This key combo normally doesn't do anything, but you can capture it with a software and then perform your own actions.
You can use autohotkey. It is a powerful and free open-source keyboard automation program, where you can write a script to do anything you want when ALT + PAUSE is pressed by RX.
Check out the official tutorials, and here's a sample configuration file upon which you can tinker with.
When you first plug RX into your mac, a window might pop up asking to identify keyboard layout, simply close it.
Go to System Preferences -> Keyboard -> Shortcuts -> App Shortcuts:
Click the box to the right of Keyboard Shortcut, trigger the TX, and it will fill in the box for you.
You can then add a shortcut to launch an application, or execute an applescript.
For more advanced scripting needs, you can try bettertouchtool, which can be considered macOS equivalent of autohotkey.
Believe it or not Daytripper also works on Android!
You can use Tasker with Autoinput plugin.
Here is a tutorial: https://forum.joaoapps.com/index.php?resources/react-to-keys-from-a-real-keyboard.79/
Oh I'm sure you'll figure it out 😉
The default settings of Daytripper demonstrates a good balance between accuracy, sensitivity, and battery life.
However, you can also adjust them to suit your particular needs.
If you purchased your Daytripper before Sept 2020, you will need to update your TX to the latest firmware. Please do so by following the USB Firmware Update section below.
Right click on the start button, then select Device Manager:
Make sure the TX is TURNED OFF, then plug it into your computer with a USB-C cable.
In the Ports (COM & LPT) section, A new USB Serial Device should appear.
Remember the number! COM5 in this case. Yours might be different.
Head here to download the latest release for Windows and macOS.
- The software is in early stages of development. If you run into any problems, please don't hesitate to open an issue, ask in the official Daytripper discord, DM me on discord
dekuNukem#6998, or contact me throughdekuNukem@gmail.com.
When trying to run the app, your system might complain about this software being untrusted. This is because I haven't had the code digitally signed, which costs hundreds of dollars a year.
Please feel free to review the code. If you don't trust the app, you can run the duckypad_config.py script itself with Python3.
For Windows 10, click More info and then Run anyway.
For macOS, RIGHT CLICK on the app and select Open. You might have to do it twice.
After the app has launched, press Refresh button, select the COM port with the correct number, and press Connect.
On macOS or Linux, the serial port will have different names, and mostly likely will have the word usb in it.
Anyway, if connection is successful, a number of options is presented:
-
Drag the slider to adjust values.
-
Click
What's this?to learn about a particular setting. -
To return to default, click
Reset to Defaultin a section, orReset allon top right corner. -
Click
Save Changesto save the current configuration to your Daytripper. -
You can make a backup of your settings with the buttons on lower left corner.
-
A description of parameters follows.
How many times per second TX takes a reading while on battery. Turn it up to make TX more sensitive to faster motions, at the expense of battery life.
Here is a table of approximate Battery Life vs Refresh Rate:
| Refresh Rate (Hz) | Battery Life (Hours) |
|---|---|
| 2 | 100 |
| 6 (Default) | 50 |
| 10 | 30 |
| 15 | 20 |
| 30 | 12 |
Please note that your battery life might be more or less depending on your lighting conditions and number of triggers.
TX will always run at fastest refresh rate (30Hz) when plugged in.
By default TX will take additional readings to prevent false triggers from sensor noise.
If turned off, TX will become much more sensitive to motion, but might also produce false triggers from time to time.
Turn it off if motion sensitivity is absolutely critical and occasional false triggers is acceptable.
Amount of time allocated to the laser sensor to produce a reading.
A larger value gives more accurate measurements, at the expense of reduced battery life and refresh rate.
I suggest leaving it at default for normal operations.
Adjust the values here if you want Daytripper to only monitor motions within a certain distance range.
The blue LED comes on when TX is triggered. You can disable it to make your Daytripper less noticeable.
TX prints some debug messages through its hardware UART. Turning it off might save a tiny bit of battery life.
Again, don't forget to press Save Changes button to save the current configuration to your Daytripper.
Daytripper uses a nRF24L01-compatible chip called Si24R1. It is less expensive, and actually has a higher TX power output, resulting in longer communication range.
Daytripper operates at channel 115, address 0xDA 0xBB 0xED 0xC0 0x0C.
Data rate is 250kbps, TX power is +7dBm, Auto Acknowledgment is used.
Daytripper TX sends 6-byte packets, details below:
-
The first byte (byte 0) is a unique identifier calculated from the microcontroller serial number.
-
Second byte (byte 1) denotes what this packet is about. It can be either a test packet, trigger packet, or status update packet.
-
The rest 4 bytes are payloads, their meaning depending on the command type (byte 1).
-
For a
Testpacket, the 4 bytes are the same incrementing sequence number repeated 4 times. -
For a
Triggerpacket, the first two bytes are the baseline reading of the power-up calibration. And the last two bytes are the actual distance reading. Unit in mm. -
For a
statuspacket, the first two bytes are the latest battery voltage reading in mV. The last two bytes are the time-since-power-on count, multiply it by 5 to get the number of seconds elapsed since TX power-on. -
The
vbat_mVis about 300mV lower than the actual battery voltage, due to the diode drop.
There is a user button on both TX and RX board. Usually they are unused:
For RX, a press on the button types out some debug messages. Make sure you open a text editor first. If the RX has not received any messages from the TX, the debug values will all be zero.
You can update Daytripper's firmware via USB, for bug fixes and and/or new features.
First, click me to download and install the STM32 DfuSe tool from this repo.
(You can also get it from the official website, but it requires creating an account.)
Locate the user button on the board:
To update firmware:
-
Make sure the board is
TURNED OFFand unplugged. -
Press and hold down the user button while plugging it into a computer.
-
Once it is plugged in, you can release the button.
-
If all goes well, the blue LED should stay off.
Now launch the DfuSeDemo software:
You should see a STM Device in DFU Mode in the Available DUF Devices section at top left corner.
- If nothing shows up, you might need to install a driver. Click me for details
Press the Choose... button and select a firmware file in .dfu format. Make sure it's the correct file!
-
Click me for latest TX firmware (1.1.2)
-
Click me for latest RX firmware (1.0.1)
-
Click me for older firmwares.
Press Upgrade button to start uploading the new firmware into the microcontroller.
And now the firmware is being updated!
It could take anywhere between a few seconds to a few minutes. Try using different USB ports if it is particularly slow.
After uploading is complete, unplug and turn it back on to start using the new firmware.
- Your custom settings will be lost after flashing a new firmware, so make sure to set it up again!
If you generated a .hex file yourself, you can convert it to a .dfu file with the Dfu file manager and then upload this way.
This method is nice for occasional firmware updates, but quite cumbersome if you want to do extensive reprogramming. It's faster to get a ST-Link programmer and use the Keil uVision IDE. See this guide for more information on STM32 developments.
There is an active-high trigger output on RX. This pin will go from GND to 3.3V for around 200ms when a trigger from TX is received.
On earlier production runs, the pin is on a testpad. On the later runs, the pin has its own header hole.
Make sure everything is on the same GND when connecting external circuits!
Unfortunately, TX does not have a dedicated trigger out pin due to limited microcontroller pins. However, there is a debug output that prints out some serial data upon triggering at 115200bps, which you can parse.
Daytripper wasn't really designed with multiple TX/RX boards in mind. I haven't done any extensive testings on this subject, however most of the time it does seem to work.
In this scenario RX will react when ANY of the multiple TX fires.
Here ALL of RX will react when TX fires.
Untested, probably a mess.
