Re: ESR meter upgrades
the frequency code that you can allegedly input any frequency is very difficult to use
I found it easy as pie.
Easier to learn than the pentatonic scale.
Took me about 15 seconds to set a frequency of 456.789Khz
If it's easy enough to recomple it to include this feature again, that would be appreciated.
Now, all of that programming stuff is what i'd call "very difficult".
OK, photo coming soon (just need to charge camera batteries)
Your last update GM328x ESR tester (SVN700)(inverted encoder) worked perfectly, except i would have preferred to have the option to 'punch in' any frequency that i wanted.
Here's the pic
With the wrong software on the chip (just to show that the frequency generator works good)
Probably a bit off because i couldn't be bothered calibrating it - but still, pretty good.
645.321khz

Re: ESR meter upgrades
Here's a better Pic, the meter possibly loses accuracy on the higher ranges.

Re: ESR meter upgrades
stj - I compiled the firmware using your makefile and I get an oversized program;
Code:AVR Memory Usage ---------------- Device: atmega328p Program: 35092 bytes (107.1% Full) (.text + .data + .bootloader) Data: 454 bytes (22.2% Full) (.data + .bss + .noinit) EEPROM: 879 bytes (85.8% Full) (.eeprom)
I also noted that the supplied precompiled st7565_kit versions do not work at all (device won't power up), nor do the make files create working firmware .

Re: ESR meter upgrades
Thanks, that's better, but the makefile needs to have the rotary direction reversed.
Opened it in WinAVR Programmers notepad, and tried Tools> Make All
But it returned this output:
> "make.exe" all
makefile:381: ../setup.mk: No such file or directory
makefile:428: ../finish.mk: No such file or directory
make.exe: *** No rule to make target `../finish.mk'. Stop.

Re: ESR meter upgrades
Downloaded transistor-tester-master.zip and extracted it into a folder
Downloaded avr-toolchain-installer-3.2.3.579-win32.win32.x86.exe, and that installed Amtel folder (not "over the top of the winavr one")
Opened up the makefile (from the extracted folder) with WinAVR Programmers notepad and then Tools> Make All.
No surprise, same errors as before
Obviously i've got no idea what i'm doing.Last edited by socketa; 12-18-2016, 04:11 PM.

Re: ESR meter upgrades
I only started playing with these chips two weeks ago so it's been an uphill struggle getting to this point Winavr should compile without the other tool chain, but you will need to copy the contents of that folder Amtel folder over into the winavr folder if you want it to be 100%
The Makefile you're opening, is it in the mega328_GM328 folder? If not, i.e. you're opening it from the zip file, that won't work. Put the updated/custom Makefile in the mega328_GM328 folder, over writing the one in there. Then open that Makefile with winavr.
Glad the one I compiled is working for you

Re: ESR meter upgrades
Hey stj, tried to compile the latest SVN version using your makefile for GM328x
But the file becomes too big in the latest SVN.
I'm using CentOS7 and avr-gcc v4.8.2
Is there something not so useful that I can remove from the Makefile to get the size down a bit?
SVN700 build:
Code:16 MHz operation configured. AVR Memory Usage ---------------- Device: atmega328p Program: 32592 bytes (99.5% Full) (.text + .data + .bootloader) Data: 206 bytes (10.1% Full) (.data + .bss + .noinit) EEPROM: 922 bytes (90.0% Full) (.eeprom)
Code:16 MHz operation configured. AVR Memory Usage ---------------- Device: atmega328p Program: 32892 bytes (100.4% Full) (.text + .data + .bootloader) Data: 206 bytes (10.1% Full) (.data + .bss + .noinit) EEPROM: 916 bytes (89.5% Full) (.eeprom)

Re: ESR meter upgrades
It's your makefile from the last ZIP: "GM328x ESR tester (SVN700).zip" that you posted here:
https://www.badcaps.net/forum/showpo...&postcount=730
And I did use your "make_frequency.c" file too, otherwise the file becomes even larger.
(My aim was not not use it, and switch back to the "standard" frequency input way too...)
