    Re: ESR meter upgrades

    btw, the zif sockets are crap, i damaged a few contacts in mine by putting caps in them with bits of solder on the leads.
    you have to clean the wires before you put stuff in the tester.
    those sockets are designed for chips with flat pins afterall.

    luckily i have seen the sockets for 99p maybe even for 2.
    one original from 3m or Aries costs as much as the whole tester!

                  Re: ESR meter upgrades

                  Trying to piece together the sources, in post #466 you posted "GM328x ESR tester (SVN684).zip" which contains:
                  changed src:
                  make_frequency.c
                  Makefile (8MHz)
                  Makefile (16MHz)
                  Transistortester.h

                  The changes in make_frequency.c where those what's described here or anything more?
                  http://www.eevblog.com/forum/testgea...772/#msg985772

                  Then in this post #2234 on eevblog is this one: "ComponentTester-trendy-1.23m(GM328x).zip"
                  Which contains:
                  changed source:
                  config.h
                  config_328.h

                  Is that it or did you modify some more files?
                  Or that together with this should be it?
                  https://github.com/svn2github/transi...Software/trunk

                  I did manage to build it on my ContOS7 machine, used this repository for avr-gcc if anyone is curios:
                  rpm -Uvh http://repo.iotti.biz/CentOS/7/noarc...7-1.noarch.rpm
                  rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-LUX
                  yum install avr-gcc avr-binutils avr-libc

                  That repository does provide avrdude v6.1 also, I compiled the latest from source though before I found this repository...
                  The version of avr-gcc is 4.9.2 which might create a bit bigger files than 4.8.x from what I've read though but I managed to compile both the 8MHz and 16MHz firmware with it.

                    Re: ESR meter upgrades

                    trendy is totally different firmware from the madiras guy on that forum.

                    as for the make_frequency.c - that is not exactly a patch - it's a heavily modded version of the old frequency generator that is no longer in the standard firmware

                      Re: ESR meter upgrades

                      Not sure I follow now, but so the one you posted on eevblog: "ComponentTester-trendy-1.23m(GM328x).zip"
                      Is that not the same source as has been used for the ones you have posted here on Badcaps?
                      If so what is the SVN URL for the ones you used?
                      Would be fun to be able to play around with some stuff on my own but gotta know where to start at least

                      Can you list the general positives and negatives with the different firmwares in your view?

                        Re: ESR meter upgrades

                        A lot has happened in the month it took for my banggod kit to arrive!

                        I decided to try and assemble the stock kit to make sure it worked..

                        Bloody hell it worked 1st time!

                        I didn't bother trying to read every post on the past 10 pages as it seemed to be a lot of troubleshooting.

                        I saw a pic in post 273
                        I take it thats what I need to do to hookup my usb programmer?

                        I have a 12mhz crystal sat here, I didn't get anything else yet as I wanted to make sure it worked.

                        Can you post up some links on how to use this programmer and what file I will need to flash to take the 12mhz crystal and your updated software.

                        Thanks

                        Oh and it came with a CBB22 cap, is that to calibrate it?



                        The test leads are a bit shit tbh, they had high resistance due to the piss poor job of connecting the cables but hopefully they will do the job for now after stripping them back.

                          post a foto of the board - not the case

                          12MHz is no good btw, only 8 or 16MHz

                            o.k. there are 2 firmwares from 2 different guys.
                            the one i posted here is from Karl Heinze Kubbeler
                            https://www.mikrocontroller.net/topic/248078

                            the one i posted at EEVblog is from Markus AKA Madires

                            it's personal opinion, but Karl's firmware is a lot more useable.


                            as for that frequency generator file,
                            the K firmware had a fixed set of frequency's you could select.
                            but they werent much use.

                            after i spoke to Karl, he re-wrote it so you could dial-in any frequency - but it was very hard to use.

                            so i took the older code and replaced the pre-defined frequency's with usefull ones.
                            (mains timebase etc.)

                                    test versions.
                                    the bangood ones probably work, but you need to let me know the best contrast value.

                                    the old text display one has 2 possible wirings, so i made both - vince - let me know which one works when your ready.

                                      Yes, there is a video on YouTube that shows the tester being calibrated with a similar cap that had been provided.


                                      Not wanting to miss out, my kit arrived a couple of days ago.

                                      Any idea what 10-bit PWM is for ?

                                        TFT - i have someone dropping one of those off to be built with extra bits soon.

                                        question, did you add the battery cable connector? i'v not seen it in the picture of parts - i thought the cable was soldered to the board?
                                        (i was going to add a molex header anyway )

                                          Re: ESR meter upgrades

                                          10bit PWM is exactly that, it can generate a PWM signal (5v) with 1024 steps controlled by the encoder.

                                          handy maybe for testing dimmers or servo's
