Detailed Description
Configuration structure of the SPIM driver instance.
Field Documentation
| uint8_t nrfx_spim_config_t::miso_pin |
MISO pin number (optional).
Set to NRFX_SPIM_PIN_NOT_USED if this signal is not needed.
| uint8_t nrfx_spim_config_t::mosi_pin |
MOSI pin number (optional).
Set to NRFX_SPIM_PIN_NOT_USED if this signal is not needed.
| uint8_t nrfx_spim_config_t::orc |
Overrun character.
This character is used when all bytes from the TX buffer are sent, but the transfer continues due to RX.
| uint8_t nrfx_spim_config_t::rx_delay |
Sample delay for input serial data on MISO.
The value specifies the delay, in number of 64 MHz clock cycles (15.625 ns), from the the sampling edge of SCK (leading edge for CONFIG.CPHA = 0, trailing edge for CONFIG.CPHA = 1) until the input serial data is sampled.
| uint8_t nrfx_spim_config_t::ss_duration |
Slave Select duration before and after transmission.
Minimum duration between the edge of CSN and the edge of SCK and minimum duration of CSN must stay inactive between transactions. The value is specified in number of 64 MHz clock cycles (15.625 ns). Supported only for hardware-controlled Slave Select.
| uint8_t nrfx_spim_config_t::ss_pin |
Slave Select pin number (optional).
Set to NRFX_SPIM_PIN_NOT_USED if this signal is not needed.
