# PicoCalc LVGL Graphics Demo
|
||
|
||
This is a template demo app using LVGL graphic engine on PicoCalc.
|
||
|
||
### TODOs
|
||
#### Done
|
||
- [x] Project support for both Pico1/2 Builds
|
||
- [x] Initial LVGL Project support
|
||
- [x] I2C Keyboard Porting for LVGL
|
||
- [x] SPI Display Porting for LVGL
|
||
- [x] Bitmap Driver flushing
|
||
#### TODO
|
||
- [ ] Improve Keyboard event processing
|
||
|
||
## Building
|
||
``` shell
|
||
# onetime, cloning latest lvgl submodule
|
||
git submodule update --init --recursive
|
||
|
||
|
||
cd {to_this_demo_path}
|
||
|
||
mkdir build
|
||
cd build
|
||
export PICO_SDK_PATH=/where/pico-sdk/is
|
||
cmake ..
|
||
make
|
||
```
|
||
|
||
|
||
## Build for Pico 1(RP2040) or Pico 2(RP2350)
|
||
if you are using other pico board, you could select a board type from the `CMakeLists.txt`
|
||
|
||
```cmake
|
||
# Setup board for Pico 1
|
||
set(PICO_BOARD pico)
|
||
|
||
# Setup board for Pico 2W
|
||
# set(PICO_BOARD pico2)
|
||
```
|
||
|
||
## How to Upload UF2
|
||
|
||
Uploading a UF2 file to the Raspberry Pi Pico on a Linux system is straightforward. Here’s how you can do it:
|
||
|
||
### Step 1: Prepare Your Raspberry Pi Pico
|
||
Enter Bootloader Mode:
|
||
|
||
- Hold down the BOOTSEL button on your Pico.
|
||
- While holding the button, connect the Pico to your Linux PC via USB.
|
||
- Release the BOOTSEL button.
|
||
- Check If the Pico Is Recognized:
|
||
|
||
Your Pico should appear as a mass storage device named RPI-RP2.
|
||
|
||
Verify using the following command:
|
||
|
||
```bash
|
||
lsblk
|
||
```
|
||
|
||
You should see a new device (e.g., /media/$USER/RPI-RP2 or /run/media/$USER/RPI-RP2).
|
||
|
||
### Step 2: Copy the UF2 File to the Pico
|
||
```
|
||
cp your_firmware.uf2 /media/$USER/RPI-RP2/
|
||
```
|
||
|
||
### Step 3: Run it
|
||
On PicoCalc, the default serial port of the Pico is the USB Type-C port, not its built-in Micro USB port.
|
||
So here is the standard running procedures:
|
||
|
||
- Unplug the pico from Micro-USB cable
|
||
- Plug the pico via USB Type-C
|
||
- Press Power On on Top of the PicoCalc
|
||
|
||
|
||
If your firmware includes serial output, you can monitor it using **minicom** or **screen**:
|
||
```bash
|
||
screen /dev/ttyACM0 115200
|
||
```
|
||
|
||
(Replace /dev/ttyACM0 with the correct serial port for your Pico.)
|
||
|
||
The serial monitor of **Arduino IDE** is another great choice for PicoCalc serial output on both Linux and Windows.
