Arduino code for changing GP2Y0E03's address over I2C
This code is heavily based on dbaba's version of code the changer I just ported it to run on the arduino enviroment, so all the credits to the main code go to him, please give him all the love for this over at his repo HERE!
Follow the diagram on page 28 of SHARP's Application Note.
Open the code and go to the first lines to change the define of the VPP pin to the one you connected on your system, and the desired Data for the NEW_ADRESS define to be programmed into the sensor according to the following table:
This instructions were also written by dbaba on his repo so go there to checkout more!
Choose the NEW_ADDRESS on the Data column value of the following table.
| Slave ID | 7-bit Address | Data |
|---|---|---|
| 0x00 | 0x00 | 0x00 |
| 0x10 | 0x08 | 0x01 |
| 0x20 | 0x10 | 0x02 |
| 0x30 | 0x18 | 0x03 |
| 0x40 | 0x20 | 0x04 |
| 0x50 | 0x28 | 0x05 |
| 0x60 | 0x30 | 0x06 |
| 0x70 | 0x38 | 0x07 |
| 0x80 | 0x40 DEFAULT! | 0x08 |
| 0x90 | 0x48 | 0x09 |
| 0xA0 | 0x50 | 0x0A |
| 0xB0 | 0x58 | 0x0B |
| 0xC0 | 0x60 | 0x0C |
| 0xD0 | 0x68 | 0x0D |
| 0xE0 | 0x70 | 0x0E |
| 0xF0 | 0x78 | DO NOT USE |
Please do NOT choose 0x08 as the corresponding Salve ID is the default value.
Updating Slave ID to 0xF0 broke his sensors (He broke 3 sensors...). So he highly recommends you not to use the address 0xF0 (data for 0x0F)
Flash the code and open the Serial Monitor on baudrate 115200 to see the process
If the monitor is displaying dot after dot that means that the operation is complete.
