TC1 lcr-meter transistor-tester fix

belzrebuth:
If I haven't done anything to firmware I should assume the diode test is disabled by default?
Because I don't think I've configured anything; just transferred a hex file to the MCU IIRC..

If you are using this firmware version(1.34m), then checking the zener diodes can only be done from the main menu in the item "Zener". Automatic zener testing, which is similar to the Chinese factory firmware, is available in newer versions of m-firmware.

@Gyro I think you may be mistaken.
TC-1 is able to test zeners so maybe my unit has a hardware problem since I've repaired it as can be read a couple of pages back in this thread.

Indeed I am. I'm clearly well out of date on these things, my apologies.

Hi Madires, this morning replaced the U4 with the 2 transistor schematic and I tried to flash the micro (see the enclosed images).
The programming has gone successful,
But all I get is that splash screen, which holds until I have the button pressed, and nothing more happens.
Maybe the firmware I used is wrong, but I don't have a link for the correct files,
Can you help?
Thanks

madires:
For the m-firmware:
- download source at https://github.com/madires/Transistortester-Warehouse/tree/master/Firmware/m-firmware
- see 'Clones' files for settings
- edit config.h, config_644.h and Makefile
- run 'make'
- run 'make upload'
