See reply #1494 (page 100) for pics of the tester board and a bug that this version has.
I registered this bug on one tester. This error is caused by a defective firmware. Flashing MCU with a functional firmware the problem is resolved.
Firmware upgrade process, I published here (post #17).
Hi.
I have one of the China import Transistor Testers, and it seems to work quite well:
http://www.ebay.com/itm/381351024208I'm trying to compile the source code onto a new ATMega128, but upon upload and startup, the red power LED is on, the LCD screen illuminates, but nothing is displayed. Perhaps I am using the wrong config.h settings? (see attached).
I've tried both this upload command:
make
avrdude -b 19200 -c avrispmkII -p m328p -v -U flash:w:ComponentTester.hex
as well as this one, from the banggood forum, above:
make
avrdude -c avrispmkII -p m328p -B 4.0 -e -U flash:w:"ComponentTester.hex":i -U eeprom:w:"ComponentTester.eep":i -U lfuse:w:0xF7:m -U hfuse:w:0xD9:m -U efuse:w:0x04:m
The chip is exactly the same ATMEGA328P-PU and I am able to burn a bootloader and upload a sample "blink" app from my Arduino.
But I simply cannot seem to make a successful burn of the Transistor tester. Any ideas?
clearly I'm a newbie at this.
any suggestions on getting the program to compile and upload correctly would be greatly appreciated.
