Data Fields | |
void * | rx_buf |
Buffer for receive data. | |
const void * | tx_buf |
Buffer for transmit data. | |
size_t | len |
Length of receive and transmit buffers in bytes. | |
uint32_t | speed_hz |
Sets the bit-rate of the device. | |
uint16_t | delay_usecs |
Sets the delay after a transfer before the chip select status is changed and the next transfer is triggered. | |
uint8_t | bits_per_word |
Sets the device wordsize. | |
uint8_t | cs_change |
If true, device is deselected after transfer ended and before a new transfer is started. | |
uint8_t | rx_nbits |
Amount of bits that are used for reading. | |
uint8_t | tx_nbits |
Amount of bits that are used for writing. | |
uint32_t | mode |
Sets one of the possible modes that can be used for SPI transfers (dependent on clock phase and polarity). | |
uint8_t | cs |
