Introducing LV_CPython: Unleashing the Power of LVGL Graphics Framework on CPython
LV_CPython is a groundbreaking CPython binding to the LVGL graphics framework, unlocking new possibilities for developers to create stunning graphical user interfaces (GUIs). Originally developed for rendering GUI controls on microcontrollers, LVGL has evolved into a feature-rich framework that can now be used on a PC using CPython. This binding allows you to seamlessly integrate LVGL into your Python projects, enabling you to develop GUIs with ease and efficiency.
Market Analysis and Addressing Needs
LV_CPython addresses the growing demand for a user-friendly and efficient graphics framework in the development community. By providing a way to run LVGL on a PC using CPython, it eliminates the need for repetitive compile, flash, and test cycles during MCU development. This accelerates the development process and enables developers to create GUIs in a shorter time frame.
Furthermore, LV_CPython caters to desktop application development. It can be used in combination with other Python GUI frameworks or as a standalone solution. On Windows PCs, LV_CPython enables developers to create graphics with transparent backgrounds, no title bars, menus, or window frames, adding a modern touch to their applications.
Additionally, LV_CPython can be leveraged as a server-side graphics framework over JavaScript. The frame buffer data can be easily transmitted over a socket connection and rendered using JavaScript on clients’ computers, providing a seamless graphics experience over the internet.
The Power of LV_CPython
LV_CPython offers two APIs: the C style API and the MicroPython style API. This flexibility caters to developers who prefer using C code on their microcontrollers or those who want to run MicroPython.
To activate the C API, simply import LVGL using import lvgl as lv, while importing import lvgl.mpy as lv activates the MicroPython API.
Setting up the display is straightforward with LV_CPython. After importing LVGL, add the following code:
“`python
import lvgl as lv
DISPLAY_WIDTH = 480
DISPLAY_HEIGHT = 320
lv.init()
disp = lv.sdl_window_create(DISPLAY_WIDTH, DISPLAY_HEIGHT)
mouse = lv.sdl_mouse_create()
keyboard = lv.sdl_keyboard_create()
“`
You have the flexibility to customize the DISPLAY_WIDTH and DISPLAY_HEIGHT variables to fit your specific requirements.
To ensure LVGL is updated and the program continues to run smoothly, add the following “main loop” code snippet at the end of your program:
“`python
import time
start = time.time()
while True:
stop = time.time()
diff = int((stop * 1000) – (start * 1000))
if diff >= 1:
start = stop
lv.tick_inc(diff)
lv.task_handler()
“`
This code snippet allows LVGL to update and ensures the program’s continuous operation. Remember to remove this code before flashing your code if using the MicroPython API or before porting if using the C API.
The Go-To Graphics Framework for MCU Development, Desktop Applications, and beyond
LV_CPython has revolutionized MCU development by eliminating the need for repetitive compile, flash, and test cycles. Developers can focus on creating mind-blowing GUIs and significantly reduce the development time.
For desktop use, LV_CPython integrates seamlessly with your favorite Python GUI framework, allowing you to create visually appealing applications with transparent backgrounds and modern graphics.
Furthermore, LV_CPython opens up possibilities for server-side graphics by transmitting frame buffer data over a socket connection and rendering it using JavaScript, making it a versatile choice for internet-based applications.
