I am trying a project to capture the image through pynqz2 board with usb camera connected to it using C++ code in vitis (2024.1/2021.1) software. I have tried to write .cpp , .h and testbench to run this code but it has many errors . Please help me to get the code for above project and i also need a code (if switch 0 is on the led 0 and led 1 should be on and switch 1 is on the led2 and led3 should be on ) it should run in vitis software

Hi,
Can you please provide the codes and the errors displayed?
Did you try chatgpt for your second code with the switch?

Yes we tried chatgpt
But still it has errors we need .cpp .h and testbench for the code please provide the code to run in vitis software and to dump the code on pynqz2 board of the second code that is switch to on led
for your first project, can you please provide the C++ code you created?

The project (if switch 0 is on then led 0 and 1 should be on else if switch 1 is on then led 2 and 3 should be on )
the code of first program has 3 file one is .cpp .h and testbench
.cpp
#include “gpio_control.h”

GpioControl::GpioControl(int deviceId, int switchChannel, int ledChannel)

throw “GPIO Initialization Failed!”;
}
}
// Initialize GPIO
int GpioControl::initialize() {
// Set GPIO directions
XGpio_SetDataDirection(&gpio, switchChannel, 0xFFFFFFFF); // Input for switches
XGpio_SetDataDirection(&gpio, ledChannel, 0x00000000); // Output for LEDs
return 0;
}
// Read the state of the switches

What is this GPIO driver header? Did you put it in the same folder as your others files?
Your problem is more a programmation problem than a board problem, You could get answer faster in a more appropriate forum, like stack overflow or C++.com .

No there are no errors . I want to know how to dump the c++ code executed on vitis 2024.1 version to the pynqz2 board .please tell step by step procedure to dump the code from vitis 2024.1 to pynqz2 board
