    which firmware version have you found that works? did you re calibrate the tester after installing the firmware?
    I tried calibrating both of these with the results as listed:

    GM328_EZM_v1.12k_r541: Board is hard to turn on. Seems to perform most tests OK but often incorrectly identifies small signal transistors as JFETs

    mega328_GM328 from current trunk at the same repo: Board turns on, but ditto with the small signal transistors.

      the pot is surplus btw, it's just rfom when they sold the lower pcb with a character display.
      it's the manual contrast setting.
      So good I did it twice:

      Code:

        are the fuse settings rite?

          Re: ESR meter upgrades

          did you actually read all that?

          it's not writing the eeprom or fuses.

          copy & past in 3 seperate operations.
          avrdude -c USBasp -p m328p -U flash:w:TransistorTester.hex

          avrdude -c USBasp -p m328p --U eeprom:w:TransistorTester.eep

          avrdude -c USBasp -p m328p -U lfuse:w:0xf7:m \-U hfuse:w:0xd9:m \-U efuse:w:0xfc:m

            btw, this looks like another windows10 fuckup.

            piece of shit cant even handle long commandline strings!!!

              I tried yesterday on windows 10 and mine failed, when you posted the three seperate commands on a windows 7 laptop the firmware load worked fine.

                maybe i should make a batch-file

                  batch-file? im still learning programming so is this just another method of loading the firmware?

                    Re: ESR meter upgrades

                    batch-file
                    you create a text file, and put command strings in it.
                    then name it xxxx.bat

                    you run it like a command and windows does whatever is in it - like a macro

                    i'll give you an example.
                    create a text file called "program.bat"

                    then copy & paste this into it:
                    avrdude -c USBasp -p m328p -U flash:w:TransistorTester.hex
                    avrdude -c USBasp -p m328p -U eeprom:w:TransistorTester.eep
                    avrdude -c USBasp -p m328p -U lfuse:w:0xf7:m
                    avrdude -c USBasp -p m328p -U hfuse:w:0xd9:m
                    avrdude -c USBasp -p m328p -U efuse:w:0xfc:m
                    exit
                    then if you type "program" or "program.bat" it will run all those commands.

                      thanks for explaning that its easier when shown commands etc too as examples.

                        the power of the command-line will never be beaten by a mouse!

                          Duh! Copied the instruction verbatim from the accompanying text file. Will redo in three steps.

                              Now reflashed and running OK. Calibrated OK, but like the other firmware I tried it has problems with small signal transistors which can either report as JFETs or a pair of diodes. If I revert to the original firmware the transistors check as expected.

                              Happy to check out any suggestions or stick with the original firmware if there's no desire to look into this.

                              Thanks either way.

                                can you upload the original firmware file im just wondering if stj can modify it into the new firmware?

                                      stj on the eevblog forum someone has just said
                                      Yes, the tester can't correctly identify integrated circuits, including voltage regulators. This is normal.

                                      so some parts it cant test properly?

                                        Just to clarify, all the parts I listed in my previous post are bipolar transistors. The list shows which ones are detected correctly and which are incorrectly identified as either FETs or diode pairs.

                                          so your original firmware tests them all ok and give the proper tests results?
