Detailed Description

Display implementation for JDI memory-in-pixel panels driven by the SF32LB LCD controller.

Data Structure Documentation

◆ DisplayJDISplash

struct DisplayJDISplash

Splash image.

Data Fields
const uint8_t *	data	Image data.
uint16_t	height	Height in pixels.
uint16_t	width	Width in pixels.

◆ DisplayJDIDevice

struct DisplayJDIDevice

JDI display device.

Data Fields
IRQn_Type	irqn	LCD controller interrupt.
struct DisplayJDIDevice.pinmux	pinmux	Panel interface pins.
DisplayJDISplash	splash	Splash image; not used by the driver.
DisplayJDIState *	state	Driver runtime state.
struct DisplayJDIDevice.vcom	vcom	VCOM inversion signal generation.
OutputConfig	vddp	Panel VDDP supply enable.
OutputConfig	vlcd	Panel VLCD supply enable.

◆ DisplayJDIDevice.vcom

struct DisplayJDIDevice.vcom

VCOM inversion signal generation.

Data Fields
uint8_t	freq_hz	Signal frequency in Hz.
LPTIM_TypeDef *	lptim	Low-power timer generating the signal.

◆ DisplayJDIDevice.pinmux

struct DisplayJDIDevice.pinmux

Panel interface pins.

Data Fields
Pinmux	b1	Blue data, odd pixels.
Pinmux	b2	Blue data, even pixels.
Pinmux	enb	Write enable (ENB).
Pinmux	g1	Green data, odd pixels.
Pinmux	g2	Green data, even pixels.
Pinmux	hck	Horizontal clock (HCK).
Pinmux	hst	Horizontal start (HST).
Pinmux	r1	Red data, odd pixels.
Pinmux	r2	Red data, even pixels.
Pinmux	vck	Vertical clock (VCK).
Pinmux	vcom_frp	VCOM / FRP signal.
Pinmux	vst	Vertical start (VST).
Pinmux	xfrp	Inverted FRP signal (XFRP).
Pinmux	xrst	Reset (XRST).

Function Documentation

◆ display_jdi_irq_handler()

void display_jdi_irq_handler ( DisplayJDIDevice * disp )

LCD controller interrupt handler.

Parameters

disp	Display device.

◆ display_jdi_test_drop_next_complete()

void display_jdi_test_drop_next_complete ( void )

Drop the next LCD transfer-complete interrupt.

Test hook simulating a lost completion. The silent-loss timer then fires about 500 ms later and crashes the system, producing a coredump. Not available in release builds.
