Workbench is a MicroPython IDE that runs in your browser, with a built-in simulator for MicroPython-compatible devices and the PyDevices libraries, and USB, Bluetooth and WebREPL connections to real boards. It's a fork of ViperIDE by Volodymyr Shymanskyy (MIT license); how the fork works.
There's nothing to install: open https://pydevices.github.io/workbench/. A browser can also install it as an app (the install icon in Chrome or Edge's address bar). To run your own copy, see CONTRIBUTING.md.
Press the simulator button, then type these lines at the >>> prompt:
>>> from board_config import display_drv
Initializing WasmDisplay...
WasmDisplay: initialized.
>>> import pygraphics as pg
>>> from palettes import get_palette
>>> pal = get_palette()
>>> w, h = display_drv.width, display_drv.height
>>> w, h
(320, 240)
>>> buf = bytearray(w * h * 2)
>>> fb = pg.FrameBuffer(buf, w, h, pg.RGB565)
>>> pg.fill(fb, pal.NAVY)
Area(0, 0, 320, 240)
>>> pg.circle(fb, w // 2, h // 2, 80, pal.CYAN)
Area(80, 40, 160, 160)
>>> display_drv.blit_rect(buf, 0, 0, w, h)
(0, 0, 320, 240)
>>> hex(fb.pixel(w // 2, h // 2 - 80))
'0x7ff'A cyan circle appears on the navy display, and the last line reads back a pixel on its edge: 0x7ff is pal.CYAN.
