It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate. ## CircuitPython Quickstart Follow this step-by-step to quickly get CircuitPython running on your board. [Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_qtpy_rp2040/) **Click the link above to download the latest CircuitPython UF2 file.** Save it wherever is convenient for you. ![install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/655/medium640/install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg?1618943202) ![](https://cdn-learn.adafruit.com/assets/assets/000/101/680/medium800/adafruit_products_QTRP_buttons.jpg?1618956837) To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RPI-RP2 drive appears!** If the drive does not appear, release all the buttons, and then repeat the process above. You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button. A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.** You will see a new disk drive appear called **RPI-RP2**.   Drag the **adafruit\_circuitpython\_etc.uf2** file to **RPI-RP2.** ![install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/656/medium640/install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg?1618943666) ![install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/657/medium640/install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg?1618943674) The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear. That's it, you're done! :) ![install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/658/medium640/install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg?1618943864) ## Safe Mode You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help. Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_. Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive. ### Entering Safe Mode To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.) ### In Safe Mode If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times. If you connect to the serial console, you'll find the following message. ```terminal Auto-reload is off. Running in safe mode! Not running saved code. CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode. Press any key to enter the REPL. Use CTRL-D to reload. ``` You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._ ## Flash Resetting UF2 If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RPI-RP2. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython. [Download flash erasing "nuke" UF2](https://cdn-learn.adafruit.com/assets/assets/000/101/659/original/flash_nuke.uf2?1618945856) # Owl IR TV Remote ## Code the Owl IR TV Remote ![](https://cdn-learn.adafruit.com/assets/assets/000/113/114/medium800/3d_printing_hero-code-remote.jpg?1657634759) Once you've finished setting up your QT Py RP2040 with CircuitPython, you can access the code and necessary libraries by downloading the Project Bundle. To do this, click on the ** Download Project Bundle**  button in the window below. It will download as a zipped folder. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Owl_IR_TV_Remote/code.py ## Upload the Code and Libraries to the QT Py RP2040 After downloading the Project Bundle, plug your QT Py RP2040 into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called  **CIRCUITPY**. Unzip the folder and copy the following items to the QT Py RP2040's  **CIRCUITPY**  drive.  - **lib**  folder - **code.py** Your QT Py RP2040  **CIRCUITPY ** drive should look like this after copying the  **lib**  folder and the  **code.py ** file. ![CIRCUITPY](https://adafruit.github.io/Adafruit_Learning_System_Guides/Owl_IR_TV_Remote.png ) Warning: ## Decode Your Pulses Each remote command for your TV is stored in an array of IR pulses. Follow along with [this guide page](https://learn.adafruit.com/ir-sensor/circuitpython) for the IR sensor to decode your remote's pulses. Once you decode the arrays that you want your owl to send from your TV remote, then you can update the CircuitPython code to work with your TV. ## How the CircuitPython Code Works The code stores two IR pulse arrays: one for powering on the TV and one for powering it off. These arrays are stored in the `signals` list for use in the loop. The `colors` array is setup with `GREEN` and `RED` NeoPixel colors. The onboard NeoPixel will change color depending on which IR command was sent. You'll edit the `power_on` and `power_off` arrays with your decoded IR pulses so that the code will work with your TV. ```python remote = pulseio.PulseOut(pwm) # power on pulse array power_on = array.array('H', [9027, 4490, 577, 563, 549, 1677, 579, 1674, 582, 558, 554, 559, 553, 561, 551, 562, 551, 1675, 580, 1674, 572, 567, 555, 1672, 573, 567, 556, 558, 554, 559, 553, 560, 552, 562, 550, 1675, 581, 560, 552, 561, 552, 561, 551, 563, 549, 1677, 579, 1674, 581, 560, 552, 561, 552, 1674, 581, 1673, 573, 1680, 575, 1679, 577, 563, 549, 565, 547, 1679, 577]) # power off pulse array power_off = array.array('H', [9028, 4491, 576, 563, 549, 1678, 578, 1701, 554, 533, 579, 561, 551, 562, 551, 536, 576, 1703, 552, 1700, 556, 558, 554, 1698, 547, 540, 582, 558, 554, 532, 580, 560, 552, 561, 552, 562, 550, 563, 549, 564, 548, 565, 547, 566, 546, 1707, 549, 1704, 551, 562, 550, 1703, 553, 1699, 556, 1697, 548, 1705, 551, 1701, 554, 560, 553, 560, 552, 1701, 554]) # array of the pulses signals = [power_on, power_off] # neopixel colors RED = (255, 0, 0) GREEN = (0, 255, 0) # array of colors colors = [GREEN, RED] ``` ### The Loop In the loop, `s` is used as the index variable and either has a value of `0` or `1`. When the button is pressed, the IR LEDs alternate between sending out the `power_on` or `power_off` pulse arrays. The onboard NeoPixel is green when `power_on` has been sent and red when `power_off` has been sent. ```python # if the button is pressed.. if button.fell: # send the pulse remote.send(signals[s]) # update onboard neopixel pixel.fill(colors[s]) pixel.show() # turn on button LED led.value = True # advance the index variable s = (s + 1) % 2 ``` # Owl IR TV Remote ## QT Py Headers ## Perma-Proto for QT Py The QT Py RP2040 will connect to the quarter-sized Perma Proto using a mix of male and female headers.  This makes the QT Py modular so it can be removed from the Circuit and repurposed. ![3d_printing_qtpy-proto.jpg](https://cdn-learn.adafruit.com/assets/assets/000/113/007/medium640/3d_printing_qtpy-proto.jpg?1657541855) ## Header Setup Use the following headers to connect the QT Py to the Perma Proto. - 2x 1x7 short female header strip - 2x 1x7 short male header strip ![3d_printing_qtpy-headers.jpg](https://cdn-learn.adafruit.com/assets/assets/000/113/008/medium640/3d_printing_qtpy-headers.jpg?1657541876) ## Install QT Py to Perma Proto Fit the two strips of male header pins under the QT Py PCB.
