ATU-100 Ext 3.2 w/Yellow Power Reading #atu-100
|
Have a 3.2 kit purchased from amazon. On boot it shows 3.2, and the power measurement is yellow, but youtubes of 3.2 show it as the same blue as the other values. Reading the unit with PicKit shows it is protected.
?
Is the power yellow on the official 3.2 from github? I would like to not lose the yellow power as it looks nice, but with it protected I cannot view/verify the cells. |

Hi John.
Please see comments below.
I hope this covers your questions.

OLED DISPLAY
The 0.96-inch OLED displays with 128 (columns) x 64 (rows) come in various (fixed) arrangements. ? ? ?White ? ? ?Blue ? ? ?Yellow/Blue (First 16 rows, upper quarter is yellow) ?
?
The OLED display I got with my ATU-100 was also the Yellow/Blue type, which I don¡¯t mind.

EEPROM
Most of the ATU-100's are shipped with the protection bits set, so you can¡¯t read or write to the EEPROM.
If you want to modify the EEPROM values, you will need to reprogram the PIC. There are several threads that cover this.
Example: /g/ATU100/message/2111
?
The hex file and User Manual are available from the GitHub site.
?
In brief, the steps I did using a PICkit were as follows.
Import the reference GitHub hex file. Turn off the protection settings in the tools tab. ? Enable Code Protect. Set to off. ? Enable Data Protect. Set to off. Write the image to the PIC. This will write the program and data values. Read back the PIC and the program and data values should be shown. ?
I had to update a few of the EEPROM address (cell) values, since the defaults were not set up for an OLED display.
Addr 0x00 - Changed from 4E to 78 (SH1106 I2C address)
Addr 0x01 - Changed from 01 to 05 (0.96 Inch OLED inverted) Addr 0x07 - Changed from 01 to 00 (Offset down = 0) Addr 0x08 - Changed from 02 to 00 (Offset from left = 0) After updating the values, WRITE back to the PIC. Read back the values and check they are as expected. ?
