Re: how to get rid of all protect msg in pickit3

 

Hi Paul,

Looking at the screen shot, is it showing the readback values or the values you tried to write?

A point to note is that the /MCLR option on the main screen should not be selected. This holds the device in reset. Unselect this option.

Another valid OLED value to try in EEPROM Addr 0 is 7A instead of 78, but all OLED displays I have used work with 78.

The meaning of the cells is covered in the manual on the github link that I had previous sent.

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
Re: how to get rid of all protect msg in pickit3

 

this is what i managed to write to the pic but still no oled working.
Re: how to get rid of all protect msg in pickit3

 

i can only turn off all rotect after dlicking the check comunication on the tools menu,if i dont do that first the data and code protect are greyed out,after changing it reverts to all protect againe.
Re: how to get rid of all protect msg in pickit3

 

Hi Paul, After disabling the code and data protect bits you need to write to the device.

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.
?
Update the EEPROM values as required.
? EEPROM Addr 0x00 - Change from 4E to 78 (SH1106 I2C address)
? EEPROM Addr 0x01 - Change from 01 to 05 (0.96 Inch OLED inverted)
? After updating the values, WRITE back to the PIC.
? Read back the values and check they are as expected.

Re: how to get rid of all protect msg in pickit3

 

as an update, if i go into tools and look at code and data protect tabs they are greyed out,if i click check cominication i can then go and uncheck code and data protect,as soon as i try and read the pic the red all protect msg shows,how do i fix this?,i am trying to read the code from a new pcb to my old one that dont work with my oled display.,help someone please+73.
how to get rid of all protect msg in pickit3

 

i am trying to program my atu-100,ir has the 16e 1938,in pickit3 it says in red all rotect so i cant write to it,how do i fix it so i can write too the pcb onboard pic with the pickit3 programmer,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?

Re: knowing what to change

 

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

current fw.hex
current fw.hex

Re: knowing what to change

 

does the atu_100_fw_ext_32.zip work with the oled as is?,cheers+ 73.
Re: knowing what to change

 

and here you get the manual:

Re: knowing what to change

 

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:

Re: knowing what to change

 

have you a link to the said manual you mention,cheers+ 73
Re: fider loss

 

Hi Paul
Feeder loss is the main parameter of certain cable you use. In decibels on 100 meters of length.
In additional, one more thing....
Loss due to high SWR.

Hi, Paul
You can order needed 3d printed parts using some printing services, it is not necessary to have your own 3d printer.?

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

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

cant upload to files section

 

was trying to upload some files from the github repo to the files section on here,it goes ok but after selecting the file the add button does nothing,is the site broken?.
