Public Attributes Documentation

variable baudrate_hz

uint32_t SYN_SPI_Transaction::baudrate_hz;

Target baud rate in Hz (0 = default 1 MHz)

---

variable bus

uint8_t SYN_SPI_Transaction::bus;

SPI bus index

---

variable callback

SYN_SPI_Queue_Callback SYN_SPI_Transaction::callback;

Completion callback

---

variable cs_pin

SYN_GPIO_Pin SYN_SPI_Transaction::cs_pin;

Target Chip Select GPIO pin

---

variable keep_cs_active

bool SYN_SPI_Transaction::keep_cs_active;

If true, leaves CS low upon transfer completion

---

variable len

size_t SYN_SPI_Transaction::len;

Transfer byte count

---

variable mode

SYN_SPI_Mode SYN_SPI_Transaction::mode;

Target SPI mode (0-3)

---

variable rx_data

uint8_t* SYN_SPI_Transaction::rx_data;

RX buffer (NULL → discard RX)

---

variable tx_data

const uint8_t* SYN_SPI_Transaction::tx_data;

TX buffer (NULL → send dummy 0xFF)
