![]() ![]() You don't have to "graduate" all at once. Second, other than the power supply, is there anything on the Arduino that I absolutely need? I guess maybe a reset switch? Then I guess I (properly) wire the connector to certain pins on the ATmega. From the bit of reading I've done, I think I need a programming cable, and a connector on my board (what type?). Of course changing the software would be inconvenient.īut for option #2, I'm not sure what I need. I'm assuming that if I go with option #1, it's as simple as inserting a programmed chip in my circuit I don't need anything else. ![]() Design my circuit to include support for in-circuit programming.Buy a programmer, program the MCU, and then place the chip in my circuit.My first question is how to program the MCU. I understand that development tools are available free or at least not very expensive.įor the purpose of this question, assume I can get +5V to my circuit. Unless there is a better option, I'm leaning towards using the ATmega328, which is used by the Arduino. ![]() I know there are methods to make my own Arduino on a breadboard, but that's not really what I'm trying to do. This will allow a single board, no shield solution. ![]() That is, I would like to use a microcontroller without involving the Arduino board. After I get everything working using the Arduino, I would like to move to a solution that does NOT use Arduino. ![]()
