stm32f7_spi_read_rx(9)

💅 stm32f7_spi_read_rx(9) 💅

Hii bestie! You’re reading the stm32f7_spi_read_rx(9) page from the Kernel API Manual, and it’s lowkey giving very specific kernel-driver main character energy. ✨

🌸 NAME 🌸

stm32f7_spi_read_rx — Read bytes from Receive Data Register. That’s the vibe, no cap. 💖

✨ SYNOPSIS ✨

void stm32f7_spi_read_rx (struct stm32_spi *spi );

🎀 ARGUMENTS 🎀

• spi — pointer to the spi controller data structure. That’s the whole argument, bestie. 🫶

🦋 DESCRIPTION 🦋

Okay so the tea: the write into rx_buf depends on how many bytes are remaining, specifically to avoid writing beyond the end of rx_buf. Boundary-checking era, fr fr. 💅
