Great. Will wait for you to get it and report.

Is this bug in the 2.2b2 code?
And if yes which code module?

the bug is for all versions less or equal to 2.2 (there were many changes in the code from v2.2b2 to v2.2), if you have version 2.2 you only need to change two lines in main.c

t1 = t0 + 4u;
if(t1 > 127) break;

to

t1 = t0 + 3u;
if((j+1)%4 == 0) ++t1;

Thanks Roderico.
Made the change in the source which is easier than redoing the pin out defs.

hey roderico, can you compile version 2.2 for KS0108, negating CS1 and CS2

hey roderico, can you compile version 2.2 for KS0108, negating CS1 and CS2

hi it's the S6B0108 firmware in v2.2 zip files

[kroman01]

I used S6B0108 and it doesn't work with RA8808 controller, you previously compiled test version 2.1 and it worked

[roderico]

KS0108 and S6B0108 are the two variants for CS1 and CS2 of v2.1 but with different names, try with KS0108 firmware then it should work with RA8808 controller

[kroman01]

I used KS0108 and S6B0108 and it doesn't work, but when I use SN74HC14 in CS1 and CS2, no problem if the KS0108 and S6B0108 controllers are the same, because if I use the version KS0108 on the display with S6B0108, it works fine

[roderico]

I don't fully understand, does KS0108+SN74HC14 work in the same display as S6B0108+SN74HC14?

[kroman01]

v2.2 software for KS0108 and S6B0108 works on the display with RA8808 controller but after negation of CS1 and CS2 using SN74HC14

[roderico]

ok I see, then the two firmwares you are using should be identical for both to work, I have just tested the latest firmware in a S6B0108 display and it works for me, then I flashed KS0108 on the same display and it does not work as expected, are you sure you didn't use the same firmware file for both tests?

[kroman01]

Currently, I do not have displays with KS0108 only S6B0108 and I can not check the interchangeability the fact is that the software on S6B0108 does not work with the display on RA8808 only the earlier test version works

[roderico]

RA8808 should work with KS0108 firmware and not with S6B0108 firmware, could you make this test: flash KS0108 firmware and connect S6B0108 display (it should not work), and then connect the SN74HC14 on CS1 and CS2 and it should work. If this is the case, then KS0108 firmware is the same as S6B0108 but with inverse logic for CS1 and CS2, i.e. what you need for RA8808

Hello roderico! Collected vdi led(4 led firmware). Thanks you! But it turned out D4 on for 0 <= vdi < 20 , D2 on for 45 <= vdi < 90.
Why could this be?
