Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

------------------------------------

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures. You may do so in a thread if the off-site link you're posting is relevant to the topic, but otherwise, don't do it. If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

        maybe now you know why it's good to have a programming header on the board!

          soldering one on the pcb etc isnt the isuue its the learning of the programming side of things im reading up on and trying too learn, things it seems to take longer as you get older.

            You are correct they mislabeled some of the pins, but the layout seems correct.
            As now verified by vinceroger69 as well

            I now tried all firmwares in "testing-chips.zip"
            The only one which gave scrolling text like with the previous files quoted below was the 7565 display firmware.
            All others just had blank display with backlight lit.

            The above two behaved like it also did with "GM328A ESR tester (SVN663).zip" which was scrolling characters on the screen.

              Thanks for testing the files per hansson i wonder if its worth now updating the eevblog thread with the information and picture stj found regarding the screen and ribbon connections.

                Re: ESR meter upgrades

                Would be interesting if you could test them too, since we know your programmer works.
                As I don't have a working chip I obviously can't be 100% sure there isn't something else wrong with mine...

                Btw, you said you can't read the firmware from your working pre-programmed Atmega chip, but can you read how the fuses are set on it?

                    i will give it a try and see if it says anything in the fuse settings

                      low f9
                      high d9
                      extended fuse ff

                        Based on the picture of the LCD module it should be a ST7920, In Karl-Heinz' documentation the ST7920 is stated as "serial" with only three I/O pins (REST = PD0 / B0 = PD2 / EN = PD5). The ST7920 got Reset, CS, SID and CLK, but they got different functions in parallel interface mode. I think the best idea is to check the source code for the functions of the three I/O pins and then to adapt the port pins to match the hardware. You might need to add some code to drive the CS.
                        so not sure if any of you guys can do the coding he mentions?

                          This firmware works but display is upside down and inverted:

                          This firmware works, display is also oriented correctly. But no MakeFile is included.

                              im new to this coding stuff so i guess the makefile is what the tester can test and values etc?

                                No it's just what is needed to know _why_ that specific firmware works.
                                I.e. it's the compilation options that the firmware is built from.

                                The source code itself is the same for all meters, it's just different options used in the makefile for what gets enabled, type of monitor, crystal, etc etc etc.
                                And of course the source code is constantly evolving, that's why new options etc can be added in later builds.
