knowing what to change

 

Hi all,i am looking to try my atu-100 with firstly an lcd then oled displays,see screenshot of it hooked up to the programer,can someone circle what i need to alter to do this as i am unshure what to change,also what to alter in the fw for 10w and a 50w version,i know about the bridge windings just confused about what does what on the pikit3 screen shot.also my hex dump attached.

Where the number screen is - under the words Program Memory there is a list in grey background down the left side. this is the Cell Number starting at 0000 with eight cells across the screen in white background, starting at the top left.

the second row starts at cell number 0008 and the third row 0010. these numbers are in HEXadecimal.

the manual describes which cell to alter for? whatever function you require. you will then need to write the changes back into the ATU-100 controller chip. simples

correction..... under the eeprom data screen NOT the program memory screen. and each line is 16 cells wide also in HEX

have you a link to the said manual you mention,cheers+ 73
 

hi Paul,
here the link to the explanation of the eeprom-cells:
/g/ATU100/attachment/2277/0/EEPROM-Cells%20Content-de_eng.pdf
and how to get the hexcode for version 3.2, look my post here:
/g/ATU100/message/2017

and here you get the manual:

does the atu_100_fw_ext_32.zip work with the oled as is?,cheers+ 73.
 

Well i flashed the above file but still no display (oled),see the fw i have read attached.,does it need altering for oled?.73

Edited

you don't have to flash the firmware. you need to adjust the eeprom settings.

Setting of EEPROM-cells/ Werte in den EEPROM-Zellen 00 ¡ª I2C address setting cell of the connected display. The port extension board for display 1602 made on the PCF8574AT chip has the address 7E, on the chip with the ¡°T¡± index - 4E. OLED displays usually have an address of 78 or 7A. It is allowed to record any address in the cell for normal operation with the connected I2C device. The default value is 4E, which corresponds to the LCD display 1602 with an extension board with the PCF8574T chip. OLED-Display= set 78?

heres a pic of the picit3 screen,grab (not mine but an example) someone explain what is what,ie what are cells etc,thanks+73
 

The field EEPROM Data?contains 4 lines with numbers.
the first line starts with 00 in grey backgroud color, there after are the cells 00H to 0FH (or 15 decimal)
the second line contains cells 10H to 1FH (or 16 to 31 Decimal)
There are a lot of docs which describes the cells contents, this is one of them:


read the Chapter?Change of default settings?

You can edit the cell data in the pickit window with your keyboard and only upload the eeprom data from pickit to the ATU
