Hi
I have this LCR-T4 which i bricked previously by messing with fuse bits and installing latest software
here is the link to post:
https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/msg1860888/#msg1860888
since i dont have high voltage programmer to reset the chip, so i bought another chip
but this one is updated one i.e. m328pb
installed the chip on the board and flashed this firmware
https://github.com/svn2github/transistortester/tree/master/Software/trunk/mega328_T4_v2_st7565but i only get backlight and no display
since i dont want to mess with fuse bit on my own so am aking here, what will be the proper fuse settings for Atmega 328pb version ?
here is the flash log
avrdude -c avrisp -b 19200 -p m328pb -P COM7 -U flash:w:TransistorTester.hex:a -U eeprom:w:TransistorTester.eep:a -v
