This example can run on zynqmp / versal platform evaluation board and IIC controller configured slave in interrupt-driven mode and Aardvark Analyzer used as master.
It uses buffer size of 250. Set the send buffer of the Aardvark device as continuous data from 0x00 to 0xF9.

void Handler | ( | void * | CallBackRef, |
u32 | Event | ||
) |
This function is the handler which performs processing to handle data events from the IIC.
It is called from an interrupt context such that the amount of processing performed should be minimized.
This handler provides an example of how to handle data for the IIC and is application specific.
CallBackRef | contains a callback reference from the driver, in this case it is the instance pointer for the IIC driver. |
Event | contains the specific kind of event that has occurred. |
int IicPsSlaveIntrExample | ( | u16 | DeviceId | ) |
This function does a minimal test on the Iic device and driver as a design example.
The purpose of this function is to illustrate how to use the XIicPs component.
This function sends data and expects to receive the same data through the IIC using the Aardvark test hardware.
This function uses interrupt driver mode of the IIC.
DeviceId | is the Device ID of the IicPs Device and is the XPAR_<IICPS_instance>_DEVICE_ID value from xparameters.h |
This function contains an infinite loop such that if interrupts are not working it may never return.
