mainmenu "I2S Loopback Test"
source "Kconfig.zephyr"
config I2S_TEST_SEPARATE_DEVICES
bool "Use two separate I2S ports for loopback"
help
Use separate I2S ports for transmit and receive.
config I2S_TEST_USE_I2S_DIR_BOTH
bool "Use I2S_DIR_BOTH value to perform RX/TX transfers"
default y if DT_HAS_NORDIC_NRF_I2S_ENABLED
help
Use the I2S_DIR_BOTH enumeration value to trigger commands in test
cases involving both reception and transmission. Use of this option
is essential for devices that cannot independently start and stop
the RX and TX streams.
config I2S_TEST_USE_GPIO_LOOPBACK
bool "Use GPIO loopback"
default y if DT_HAS_NORDIC_NRF_I2S_ENABLED
help
Use wiring between the data-out and data-in pins for looping back
data. This option is intended to be used for devices that do not
provide the internal loopback functionality.
config I2S_TEST_ALLOWED_DATA_OFFSET
int "Allowed offset in received data"
default 2 if DT_HAS_NORDIC_NRF_I2S_ENABLED
default 0
help
Maximum allowed offset between sent and received samples. Non-zero
value of this option may be needed when GPIO loopback is used.
