GLCD KS0108 DEMO WON'T START

[Howard Hammond]

I have attached my schematic, it is made using Eagle software

[Anobium]

Post a JPG of the schematic please. This computer has no design tools.

---

Please - take a photo of the back of the GLCD. I will see if I have something like it.

[Anobium]

Also, if you have a scope or meter. Test each connection.

Ensure you have power cycled the chip before starting to clear any PPS.

Please test the signal at the LCD.

Attached is a PDF of my schematic, if you can't read it I can zoom in on the GLCD area and send you that.

[Anobium]

Also, what are using to program? is this setting the debug bit in error?
Using your programmer - read the chip, export the HEX. Post here... it should be the same as mine.

[Howard Hammond]

Attached is the read. I did not read the EEPROM.
I am using PICKIT2 minus

[Anobium]

Truly not good to hear that you are using PICKIT2 minus. That is plagiarised work of mine and it is really hurting the project as the PICKitPlus funds partly paid for this GCBASIC project.

The HEX is verifies here and works.

So, you are looking at local functional issue. Connection, GLCD type etc.
Really puzzled here. This did work with another compiler? I wonder...

[Howard Hammond]

Have to take my wife to the Doctor, be back within the hour

[Howard Hammond]

PICKIT2 minus has really been the best for me.
What is PICKITPLUS something I should look into?
I have PicKit 5 but that is way to complicated.
I will be donating once we get this figured out and I will have many other questions as I try to program all the other areas of my project.

.
I do not have an Oscilloscope but I do have a digital meter not sure it will be fast enough.
Explain to me exactly what I am measuring, CS1 or all 8 data lines and what am I looking for?
You said 14 measurements but there are 8 data lines.

[Anobium]

I did all the hardware spending many years on updating the PICKItPlus database. Taking the database with no attribution is no nice. www.pickitplus.co.uk and you full support when you buy a license.

re Testing. The test program above toggle each port. Check the pin on the chip is toogling and then check the correct connection on the GLCD. Do this for every connection. You just need to change the constant ( do not use portx. y as this does not test constant replacement). Make sense? Every connection should toggle.

[Howard Hammond]

It appears PICKIT PLUS is just software using pickit 2 is that correct?
Can you tell me which version would be best for me?

Back to the test I am going to do. I am confused since the software you added only toggles CS1.
Am I supposed to change that software for every port I am testing for example RS,EN, R/W,CS2, RST, D0 to D7? That's what I am going to do.

No PK2 and PK3.

Yes, change ONLY the constant for TESTPORT to each of the GLCD constants, two tests per port ( at the chip and at the GLCD).

[Howard Hammond]

First part of test is done. All pins on pic18f47k42 are toggling
I will now do the pins on the GLCD
I need to get setup by mark the ports

You are in London my time here is 1:55 what is yours and when do you leave?

[Howard Hammond]

Finished testing the GLCD ports all are pulsing.

I then changed out the pic1847k42 and ran the complete program not the test.
Still nothing

[Anobium]

Hard to figure this out. Can you send me one of the GLCD?

I have written many, over 40, GLCD libraries. It is hard without the actually GLCD. These GLCDs have very odd pinout, a different chip but they are from SureNoo. SureNoo are good products.

The attachment is my golf cart speedometer. My project is to replace the PIC18F.

Hit the wrong button

I can send you my GLCD but I probably can order one from China for less money than it would be for me to ship one to you and you would get it in about the same time.
Give me your address and I will see if I can do it.

I have been using a couple of different versions of this GLCD all with the same pin out so for me it is not an odd pin out

[Anobium]

I will send details via a Personal Message.

[Howard Hammond]

I have not got your address, do you still want e to get you the GLCD?

[Anobium]

Yes, I have sent you a Personal Message. Have you received ?

[Howard Hammond]

Yes but I need your shipping addtress.

[Anobium]

Emailed direct to you.

[Howard Hammond]

Better send again, all I got in your email was your email address, need shipping address.

[Anobium]

Check email at address pXstoXXump@coXcast.nXt I have sent there.
Check trash, spam etc.
