Arduino ed

I'm having the cheap clone from Maker Factory, with an atmega328p. Trying to work on Manjaro linux.

Arduino IDE ed

Setup ed

• open the board manager (menu tools/boards)
• install "Arduino AVR boards"
• select the "Arduino Uno"
• programmer: "ArduinoISP"
• port: "/dev/ttyACM0"

Giving upload permission to normal user:

sudo chmod a+rw /dev/ttyACM0

Serial monitor ed

Had Java errors first, because my system used an outdated version of java.

check

archlinux-java status

set

sudo archlinux-java set java-10-openjdk

Some goals ed

0.98' OLED display ed

In IDE, install libraries:

• Adafruit SSD1306
• Adafruit GFX Library

Connect to random pins and edit code accordingly:

#define OLED_MOSI  11 // -> D1
#define OLED_CLK   12 // -> D0
#define OLED_DC     9
#define OLED_CS     8
#define OLED_RESET 10

wifi: ESP8266 ed

Connection... 3V3, GND, D0, D1...

Test

flashing an image

avrdude -p atmega328p -P /dev/ttyACM0 -c arduino -U flash:w:main.hex

Can upload, but sadly, no digital output yet...?
