heres a jpeg,hope its better.

Hi all,i am trying to get my atu-100 going with an 1602 + ic2 pcb working? together,see the screenshot of the pic program and tell me if its ok please .

i just get a 404 error if i try and use the links on the pickit 3 sw i have,any links for an udate?,thanks m3vuv73

on the pikit3 about it says application version :3.10.00 DEvice file version :1.62.15 os firmware version :2.00.05

Hi Paul Can you check your version

Hi with my picit3 connected too the atu-100 board,i can read the pic but when i click on cell 00 it just turns blue and wont change as i type,is this a bug/fault?,i am trying to change it from 00 to

can someone post a screenshot of the pickit3? screen with it setup to make the atu-100 3.2fw work with the 1602+ ic2 board ,so i know what to alter in the cells as still not sure what cell is what

the only way i get the data+ code protect not greyed out is by clicking check cominication first,where do i get the pickit3 updated zip,have you a link?,thanks.

Paul Open the pickit software and go under tools and click disable write protect . Do you have the updated pickit zip file ? I just checked mine and the option is not greyed out ! i hope this

well i flashed the 3.2 fw and had code and data protect turned off,it seems to have removed the all protect warning in red,i am trying to make it work with the lcd with ic2 pcb,i changed one cell to

I find it impossible to read any data from the 16f 1938,all i get is zeros in all fields,if i reflash the chip with 3.2fw it writes ok but the all protect re appears as soon as i try to read it,how do

ok i cleaned the ic2 pcb and read it as 8574t,but the issue is the words all protect are in red,if i go into tools and look at code and data protect they are greyed out until i go tools check

from what i can read on my 1c2 adaptor bord chip number it looks like 87541,does that look plausable,if so what too change /program into the atu pcb pic?,thanks.

You can edit the cell data in the pickit window with your keyboard and only upload the eeprom data from pickit to the ATU 73 Ton PA0ARR

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

and the address can be modified using the three links A1, A2, A3 just below the contrast pot. see the PCF8574 datasheet for details

Hi Paul, I think most i2C adapter boards with the 1602 displays have the PCF8574T, so EEPROM Addr 0 = 4E. 73, Dave

Hi Paul, The value depends on the device on the I2C adapter board. From the manual: PCF8574AT, EEPROM Addr 0 = 7E PCF8574T, EEPROM Addr = 4E 73,Dave

ROFL

but i have pic 1938 tho dave not pcf8574at.
