stm32fx_spi_...ne_dma_start(9)

💅 stm32fx_spi_transfer_one_dma_start — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in the kernel, the stm32fx_spi_...ne_dma_start(9) page is open, and it's giving very serious kernel API energy. this is that page, but make it make sense. it's from the Kernel API Manual, section 9, and yes the title is literally truncated with dots — that's not me being lazy, that's the manpage being iconic and mysterious 🎀

🌸 NAME 🌸

stm32fx_spi_transfer_one_dma_start — sets the SPI driver registers so the transfer can kick off using DMA 💫

like, it's the little setup goblin that gets the registers ready, and then the DMA does its whole main-character thing. no cap.

---

🦋 SYNOPSIS 🦋

void stm32fx_spi_transfer_one_dma_start (struct stm32_spi *spi );

that's it. that's the whole signature. she's a void, she returns nothing, she simply does 💅

---

🍓 ARGUMENTS 🍓

• spi — pointer to the spi controller data structure 🌈 this is your struct stm32_spi *, the one that knows everything about the controller you're working with. hand it over and let her cook 🫶
