ili922x_read(9)
β¨ NAME β¨
ili922x_read β read a register from the display π
okay so bestie, quick vibe check: this is a kernel API manual page, section 9, and it's all about pulling one little register value out of an ili922x display and dropping it in your output variable. that's it, that's the whole errand. iconic behavior, no notes. π
πΈ SYNOPSIS πΈ
int ili922x_read (struct spi_device *spi , u8 reg , u16 *rx );
literally the whole signature, character for character, don't come for me π«Ά
π¦ ARGUMENTS π¦
spiβ the spi device, aka your main character. you hand it over so the function knows which display it's talking to π«regβ the offset of the register to be read. lowkey the address of the little drawer you're opening πrxβ the output value. this is where the answer gets dropped off, so make sure it's pointing somewhere real, bestie β it's an output, not an input π
