That ‘hardware’ programmer could also be emulated in software. The -c parameter specifies the ‘hardware’ programmer being used. (By the way, this configuration file does specify and recognize both the ATmega328 and ATmega328P.) The -p parameter specifies the part (i.e. The -C parameter specifies the file with various microcontrollers AVRDUDE can program and their respective identities. I will leave it up to the reader to consult the AVRDUDE documentation if they are interested in the other parameters. We are specifically interested in three parameters (-C -c -p). The Arduino IDE runs AVRDUDE in the background with specific parameters on how it should run. AVRDUDE ‘talks’ to various hardware (and software) programmers which physically connect it to the microcontroller chip. Here is how things are physically connected:īehind the scenes, the Arduino IDE uses the AVRDUDE software to do the programmimg (uploading the sketch). Let’s take an example of how the Arduino IDE burns the bootloader for an ATmega328(P). Since the ATmega328 is not used in an Arduino, that chip is not recognized/used by the Arduino IDE unless we make some changes. Even though they function the same, they have different signatures. There are ‘minor’ differences between the ATmega328 and ATmega328P but for my purposes the ATmega328 works essentially the same as the P version. An original Arduino UNO has an ATmega328P microcontroller. While making a new batch of my DIY Arduino UNOs I bought some ATmega328 microcontroller chips. So an ATmega328 with two identities is possible. However, sometimes, a program it runs speaks for it and tells a different story. Therefore, a chip has only one built in identity, that is, if you ask it. This protects the microcontroller from user error. When you program a chip (for example, upload a sketch in the Arduino IDE), the process checks that the chip selected matches the type it’s connected to. This signature is a unique code that identifies its model. Microcontrollers from Atmel (AVR) and Microchip (PIC) have a built in ‘signature’ or identity. □ First though, before we ask, here is some necessary background information. ![]() Get the most out of your time and work from a single secure Workspace.Some would say that an ATmega328 with two identities is not possible.
