The I2C test validate proper implementation of the I2C hal.
To run the I2C hal tests, use the command:
mbed test -t <toolchain> -m <target> -n tests-mbed_hal_fpga_ci_test_shield-i2c
| void fpga_i2c_test_async_abort | ( | PinName | sda, |
| PinName | scl, | ||
| uint32_t | frequency | ||
| ) |
Test that call aborts ongoing asynchronous transfer.
Given is asynchronous transfer ongoing. When call . Then transfer is aborted, and callback doesn't triggers and stop condition is generated

| void fpga_i2c_test_frequency | ( | PinName | sda, |
| PinName | scl | ||
| ) |
Test that i2c_frequency() sets the frequency used during the I2C transfer.
Given is platform with I2C support. When i2c_frequency() is called and valid frequency is specified. Then function is executed successfully and actual frequency which will be used during the transfer is returned.
| void fpga_i2c_test_get_capabilities | ( | ) |
Test that i2c_get_capabilities() fills given i2c_capabilities_t instance with capabilities.
Given is platform with I2C support. When i2c_get_capabilities() is called. Then function fills the given i2c_capabilities_t instance.
