OpenCR Arduino Test - EEPROM

7. 6. OP3

OpenCR is used for power and sensor control in OP3, a humanoid robot. If the OpenCR

firmware for OP3 has been changed, follow the procedure below to update it.

7. 6. 1. Preparations

OpenCR develops and downloads firmware through the Arduino IDE. Therefore, you must

install the Arduino IDE in advance and install the OpenCR board package. Install through the

following link document.

Install Arduino IDE and OpenCR

7. 6. 2. Download OP3 firmware

1. To update OpenCR’s firmware, open the front cover of OP3 and connect USB to PC as

shown below.

2. After connecting USB, select Tools-> Board-> OpenCR Board in Arduino IDE.

3. Change Tools-> Port to the port to which the board is connected.

4. In the Arduino IDE Examples, select the firmware for OP3.

if (Serial.available())

{

uint8_t inByte = Serial.read();

if( inByte == '1' )

{

EEPROM.write(0, i+1);

EEPROM.write(1, i+2);

EEPROM.write(2, i+3);

i++;

}
