    Help with programming an EEPROM

    I fried my component tester by not discharging a cap. Now I've been trying to reprogram the Atmel 328 (new) with no luck.

    Does anyone know how to program Picture 1 with picture 2? Thanks!

    Re: Help with programming an EEPROM

    You need the running data file (bin or hex file) and there's every possibility that the original microprocessor in the tester is damaged.

      Re: Help with programming an EEPROM

      Thanks DB,

      I did buy a new one and swapped the Atmel chip and the old one works with the new chip.I was hoping I could copy the data from the new chip to old (new) chip with the minipro. No luck. This project is more of a learning curve than trying to fix the device. they are cheap to replace.

      I'm looking for "do this, then do that" type of instruction.

        Re: Help with programming an EEPROM

        I suspect the original chip is locked (fuse bits)to prevent reading/coping

          What is the part number of the Atmega328Pxxx?

            If you can work your way through the documentation you should find the software as open source on the following pages.

            https://www.mikrocontroller.net/arti..._.28English.29

            Once you have the software I'm sure someone would be able to help.

              Getting closer, thanks for the help so far. I'll post a solution if you all are interested (if I get one). Have a nice evening! Hot here! For us anyway.

                I have both of these items myself i will find the guide i used too update mine and the hex and bin files but if you search this site theres a thread with all the information you need in it

                from page 11 onwards
                https://www.badcaps.net/forum/showth...tester&page=11

                also some good info in this thread too
                http://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/

                The only thing you need to do is to load the TransistorTester.hex in the "Code Memory" and the TransistorTester.eep in the "Data Memory"
                Pay attention and use always "INTEL HEX" as File Format when you load the files. By default the TransistorTester.eep will be recognized as Binary and you have to change it during loading

                  Thanks Vince, a lot of info in the thread you posted. I will try this after work today and post back.

                  The picture I used (tester) is slightly different than mine in that mine has all SMD components not through hole, does it make a difference?

                    Re: Help with programming an EEPROM

                    yes as my firmware wont work on your tester post a picture of your tester and we can see if we can find the correct firware version has yours got the original 8mz crystal still? as most of us have updated to a 16mhz and some extra fuctions in the new firmware its all in the eevblog thread too be honest but using the programmer use the guide i have posted as works fine just make sure the fuse setting part is set rite as it does cause errors if its not.

                            i honestly have not saw that tester before my advice is post a picture and amazon link on to the eeblog thread what i would do is keep the working ic as it is and maybe if its not damaged use your old ic put the firmware what the eeblog forums recomends onto that and give it a try as the font size etc maybe diffrent but usually the firmware is a lot better and more accurate. dick-bartons link has the firmware links but i have no idea which version you need to try but also remember you old ic maybe damaged and require a new one.

                              Thanks for your help VR69! I am trying to program a new Atmel 328. I bought 10 of them to practice with.

                              Can you post a link to the BUILT one you purchased, I would like to compare, thanks again!

                                i have two one with the standard 8 mhz crystal one i upgraded to 16 mhz crystal and firmware

                                have you tried copying your working ic data on too a new ic that way you get used to copying and adding the files etc and see it working.

                                  Yeah, I've been messing around with it. I'm where you were where I get the screen to come on for 5 seconds, but can't see anything on the screen. It could be the Intel Hex thing. I'll try tonight after work.

                                  I tried to copy the new IC files, it is locked, just a bunch of FF FF FF.

                                    yes i had that issue too try the hex/bin files and make sure the fuse settings match as per the picture i posted
                                    i have just checed both of our testers use the same lcd screen so in theory the files i attached should work

                                      IT'S ALIVE! Thanks VR69! It worked using the files and suggestions you provided.

                                      It's asking to be calibrated, What 3 pins do I clamp together?

                                        Glad the tester now works im sure its the three pins you need to join together but you will also need a capacitor to calibrate the unit i have attached the tester manual all the info required is in there

                                        this video will give you a rough idea on how to calibrate the unit

The data sheet for both is below:

                                          Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me

                                          1). Understand the schematic and check the connections between the EEProm and DSP
                                          2). Check the functionality of the EEProm

                                          I don't know if this is the unit's problem but it's a place to start.

                                          I have little to no electronic experience...

                                          Macbook Display EEPROM Programming

                                          Hello,
                                          Namaste!

                                          Recently while doing Macbook Display repairs - due to a mishap by the supplier, we found that certain Macbook LCDs are cross -compatible but have Brightness issues.

                                          Some are DIM after start-up and some stay at Max brightness with the brightness control being disabled.

                                          While speaking to my supplier they said that they can program the LCDs at the Factory so that the brightness issue was resolved.

                                          I was wondering if there were a way we could do the same? I came upon a video online as well. Here is the link >...

                                          24C04 Eeprom programming?
                                          by ducky29
                                          Hello. I have to read a 24c04(404rp) eeprom msop8 package but currently don't have an adapter for it. I have read couple comments that claim that you can read by connecting only some pins of the eeprom, only serial data and serial clock. Has anyone tried this or is there any way how to read the data without desoldering the chip?

                                          Damaged EEPROM on TV Vizio E320-A0
                                          by edgarmg15
                                          Hi everyone

                                          I´m trying to repair a TV Vizio E320-A0 that I found in the street

                                          The symptoms are it doesn't respond with remote or buttons, the LED indicator is always off and also there is no image on the TV.

                                          The power supply board works fine (I probed the terminals with my multimeter) but in the main board the EEPROM doesn't works correctly because the voltage on the pins doesn't match with the parameters of the datasheet.

                                          So, I´m going to replace the EEPROM with a new one, but the problem is that my programmer (CH341a)...
