Step 1: 元件清单
1 x FT232RL chip
1 x ATMEGA328P-PU microcontroller
0.1 uf capacitor
Step 2: 连接和上传
This instructable was made in a hurry and I think the connections in the image are wrong. Should be RX -> pin 3 and TX to pin 2.
FT232RL -> ATMEGA328
DTR via 0.1 uf capacitor > pin 1
RX -> pin 3
TX -> pin 2
VCC -> pin 7
GND -> pin 8
Pin 7 (+) -> pin 20 (+)
To upload sketches is the same as usual.
Make sure you select the right port.
If your ATMEGA328 is running at 8Mhz select “Tools → Board” and select “Atmega 328 on a breadboard (8MHz internal clock)”.
If your ATMEGA328 is running at 16Mhz select “Tools → Board” and select “Arduino Uno”.
Step 3: Tip
I have soldered the capacitor and the wires to my FT232RL chip so now it's very easy to use.
It is good practise to solder male or female header pins to pin 1, 2, 3 and to + and - so you can still upload and change the program on the microcontroller without having to remove the chip.
