Alternative FW for U4 (STC15 8051 uC) on TransistorTester TC1

tc1-u4's Issues

my mistake

The instructions did not indicate that you still need to flash atmega, so I could only flash U4. After that, he stopped working.
You can give a dump of U4, for the Chinese version firmware?

v0.3.1 & v0.3.0: second time tester powers up with "Bye!" message and won't turn off

Thank you for providing custom firmware for the timer chip! It's great for us hobbyists who want to run the latest firmware from Markus and Karl-Heinz.

I have an LCR-TC2 tester with ST15W104 timer chip.
After programming it with v0.3.1 or v0.3.0 timer chip firmware, initially the tester seems to work ok.
Pressing the button wakes up the tester, the firmware version (1.47m) is displayed, and it repeatedly probes and displays the installed component until the button is held in. Then it briefly flashes "Bye!" and turns off.
The next time the button is pressed with no component installed, the unit wakes up again, but immediately goes to "Bye!" message (skipping firmware version), and does not shut down. Additional button presses have no effect at this time; the only way to reset the tester is to remove the battery, wait a few seconds, then reinstall it.
Also, selecting the "Off" menu option turns of the tester with "Bye!" message, however, the next time the button is pressed the same problem happens as outlined above.
There seems to be a timing issue(s). Maybe the button is not being debounced properly?
Would you please help? Thanks!
