AVR Microcontroller – ATMEGA minimale onderdelen
Minimale onderdelen voor een ATMEGA 328P: Bron
All you need apart from the programmer and the chip is a couple of decoupling caps, and some way of connecting the programming signals to the breadboard.
- 1 largish electrolytic cap (e.g. >100uF) You can maybe do without this if your source is nice and quiet (e.g. battery)
- 1 100nF ceramic across the power pins of the micro
- 1 10kΩ resistor to connect from the reset pin to Vcc to hold the micro out of reset.
- Some jumper wire to connect up nodes on your breadboard (you can buy ready made jumper wires, but I use a 22AWG roll and cut my own – much cheaper if you do this a lot)
- A header to plug your programmer cable into. According to the user guide it looks like you need a 2×3 pin 2.54mm pitch header.
- A button to connect your reset line to ground if you wish to physically reset the chip (I don’t use AVRs, but I’m 99.9% certain the programmer can do this from the IDE)
- A crystal to use instead of the internal oscillator
- 2 * 22pF capacitors for the crystal (place from either side to ground)
- Passive components, LEDs, sensors, etc in order to do something useful with the code you write ;-)
Apart from the header (which is 10-pin with some unused pins – you can use the labels as a guide for your connections, the names are the same) this schematic is about the simplest I could find with a quick Google:
