![]() If you are building on CentOS7 or RHEL7 I made a small writeup here.
If not the version of GCC should still be relevant no matter what build OS you have. https://www.badcaps.net/forum/showpo...&postcount=773

![]() I have just received a couple of 16mhz crystals and fitted one to my T4 tester
with the old program which is v1.12 all the capactors read double there value where as resistors and transistors seem to read within tolerence, I have tried several 16mhz firmware upgrades with no luck just a blank screen, any suggestions ? if all else fails I can always revert to the 8mhz crystal. the original firmware was V2.68 which I lost due to corruption and damage to the original chip, (my fault) did not discharge capacitor.

![]() Piece of s*$#(%t...
I remember having so much trouble making sure that gcc fit everything in flash and got so pissed off when gcc version bumps caused bloat, and it's still a problem... ![]() |

![]() I was pissed off that I kept 3.3.something for a long time because it produced the smallest code...
Alas had OS compatibility issues as it was kept back for so long and forced to delete it. |

![]() Same board as TEDDIBEAR have.Except crystal at 16MHz.
Replaced push button with encoder. Tested few versions,some no display,some display OK but only push button works no encoder. Finally found this one https://www.mikrocontroller.net/svnb..._T3_T4_st7565/ But crystal on board was already 16MHz so display double value. Change value in makefile and works fine. |
