Hello everyone,
I developed my first "custom Arduino2560 board", and it aims to be used with a Labview application using LINX.
I would like to have more details about how to first program it.
Some of the pin are unused (unbound), and I know that I will have to declare it somewhere to activate internal pull-up resistor by this way for example:
DDRA = 0x00;
PORTA = 0xFF;
If I wanted to use it with the Arduino IDE, I saw that it has to be implemented in the ISP bootloader.
My questions are:
- Can someone tell me what is the difference between a firmware and a bootloader?
- Where those lines have to be implemented? In the pre-built firmware generated by LINX?
Thank you
