stm32fx_spi_dma_tx_cb(9)

okay bestie, welcome to the stm32fx_spi_dma_tx_cb(9) page from the Kernel API Manual — yes, the manual name is folded in right here so you don’t have to scroll for it. This one is short and sweet, but we’re still giving it main character energy. 💅✨

💖 NAME 💖

stm32fx_spi_dma_tx_cb — dma callback 🎀

🌸 SYNOPSIS 🌸

void stm32fx_spi_dma_tx_cb (void *data );

🎀 ARGUMENTS 🎀

• data — pointer to the spi controller data structure 🫶

🦋 DESCRIPTION 🦋

okay so the DMA callback is called when the transfer is complete for the DMA TX channel. That’s the whole vibe check: TX DMA done, callback time, slay. ⭐
