The full FreeWili OneWili command API for firmware running on the FreeWili 2 display CPU (WiliBSP, RP2350B). The library is the same generated C package the PC serial target uses; only the transport differs: commands travel to the main CPU over the FwGUI display link (UART0, 8 Mbaud, hardware flow control on GPIO0-3) and responses/events travel back on the same link.
The main CPU must run the default FreeWili 2 firmware (which carries the OneWili display bridge).
#include "onewili.h"
#include "onewili_fwgui.h"
ow_device dev;
ow_open_fwgui(&dev); /* UART0 + link handshake */
/* any generated call, e.g.: */
ow_io_gpio_set_io_toggle(&dev, 25); /* toggles a MAIN-CPU gpio */Text events arrive in-band — poll with ow_poll_text_line(&dev, ...).
Binary events (onewili_binary.h):
ow_binary_device bdev;
ow_transport bt = ow_fwgui_binary_transport();
ow_binary_open(&bdev, &bt);
ow_event ev;
while (ow_binary_poll(&bdev, &ev) == 1) { /* ... */ }Poll events regularly: each stream buffers 1024 bytes and whole frames are
dropped (counted by ow_fwgui_dropped_frames()) when a buffer is full.
Logic-analyzer binary reports are never mirrored over the display link.
CMakeLists.txt builds a onewili_fwgui static library against the
pico-sdk. Link it from your wilibsp app target and add include/ (PUBLIC,
automatic via CMake). examples/blink.c is a minimal app body.
