STRUCT DAVINCI_SPI_CONFIG(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct davinci_spi_config — Kernel API Manual, but make it group chat 💅

okay so bestie, this is the <pink>Kernel API Manual</pink> page for struct davinci_spi_config(9), and it is literally the per-chip-select configuration for SPI slave devices. Main-character struct energy, no cap. 🦋✨

🌸 NAME 🌸

struct davinci_spi_config — per-chip-select configuration for SPI slave devices. That's the whole assignment. 💖

✨ SYNOPSIS ✨

       struct davinci_spi_config {
           u8 wdelay;
           u8 odd_parity;
           u8 parity_enable;
           u8 io_type;
           u8 timer_disable;
           u8 c2tdelay;
           u8 t2cdelay;
           u8 t2edelay;
           u8 c2edelay;
        };

🎀 Members 🎀

  • wdelay — amount of delay between transmissions. Measured in number of SPI module clocks. ⏳
  • odd_parity — polarity of parity flag at the end of transmit data stream. 0 - odd parity, 1 - even parity. 🎚️
  • parity_enable — enable transmission of parity at end of each transmit data stream. ✨
  • io_type — type of IO transfer. Choose between polled, interrupt and DMA. 🔀
  • timer_disable — disable chip-select timers (setup and hold). 🛑
  • c2tdelay — chip-select setup time. Measured in number of SPI module clocks. ⏱️
  • t2cdelay — chip-select hold time. Measured in number of SPI module clocks. ⏱️
  • t2edelay — transmit data finished to SPI ENAn pin inactive time. Measured in number of SPI clocks. 🔌
  • c2edelay — chip-select active to SPI ENAn signal active time. Measured in number of SPI clocks. 🔌
