The question translated:
How much current can pin 2.4 or 2.5 drive. Using CY8CKIT-059, A resistor and two diods in line?
The datasheet for the pins component shows exactly what you want. Keep in mind that there are two different situations:
Maintaining the logic level (Lo and high) maximum for the pin will be 4mA source and 8mA sink.
When the logic level is not needed a pin can drive up to 20mA, restrictions exist for using more than 1 pin at higher currents.
The two diods in your case reduce the output voltage and the resistor will control the current. Just calculate using Ohm's law.
