VDI-RODERICO

[Wiltran]

I'll try it Thank you!

[roderico]

yes, the pinout would be (I included the pin numbers you wrote in parenthesis)

KS0108-> ST7565

VDD -> VDD (9)
VSS -> VSS (10)
V0 -> ---
CS1 -> /CS (12)
CS2 -> /RST (13)
/RST -> A0 (14)
RW -> /WR (15)
RS -> ---
EN -> /RD (16)
DB0-7 ->DB0-7 (1-
VEE -> ---
A -> LEDA (11)
K -> ---

you don't need V0, VEE, RT1, contrast is controlled by the firmware

[Wiltran]

So for use with the ST7565 display the VDI board CS1 and CS2 are connected to ST7565 display pins CS and RST?

[roderico]

Hi pins are shared by different displays, e.g. CS1, CS2 in KS0108 are CS, RST in ST7565, pin RS is no used in ST7565 and so on, V0, VEE, RT1 are for KS0108 contrast, not used in ST7565. You don't need the backlight during dayligth but you can have the backlight control if you connect pin 11 to A+ pin, just match the display labels with the schematics labels, e.g. pin 16 would be RD, and pin 11 would be A+, the others as you already wrote

Hello Roderico! I am trying to connect a Zolen parallel ST7565p display. the pins on the display are as follows:

1-8DB0-DB7
9 Si, VDD,+5v
10 VSS-ground
11 backlight power supply+
12 chip select /CS
13 /RST reset signal (low effective)
14 A0 D/I data/instruction select
15 /WR write signal
16 /read signal

My questions :
do K-, A+ and VEE have to be connected?
does backlight have to be connected to view in the daylight?
what does V0 connect to?
what connects to CS1 and CS2?
what does RS and EN connect to?

thanks

Kicad should work at least up to Windows 10 according to https://www.kicad.org/help/system-requirements/, you might have also found this page https://www.kicad.org/help/windows-d...-verification/ or maybe someone that is using kicad in windows knows what the problem is, but if somehow you manage to install kicad then you can easily customize the pcb, e.g. push buttons, display connectors, pcb size, and so on. For the display I would suggest a ST7565/ST7567 (8080 parallel interface 5V) because they are lighter than KS0108 displays and you can find them in the same sizes e.g. 71x57mm but all of them should work well, wltr even made it work with an OLED display

[Wiltran]

Thanks Roderico, yeah, I tried downloading Kicad from 3 different locations but Windows would not accept the digital signature. Kicad looks like a good program, it has the negative output that I use for making circuit boards. Now all I have to do is get a graphical display. thanks again!

[roderico]

yes no problem, I have just exported the negative image of the pcb to pdf with a newer version of kicad and in principle it looks fine, see the attached file

[Wiltran]

Hello Roderico, any chance you might have a negative version of the vdi-pcb-pdf.2.2? I tried downloading Kicad, and it wont install because Windows wont accept the digital signature,thanks.

Also, try putting the display back on the board it worked on. I have had these display simply DIE. Two that died I troubleshot and found the charge pump chip on the display died. Found a replacement and got them working again.

Ignore this:
I posted without seeing that it is now working with different firmware version.

Great that it works.

Now I will know about it too. I will do it as an independent VDI prefix to Whites IDX and Tesoro Bandido. Thank you very much again!!!

[roderico]

we had the same problem at the beginning with kroman1's displays the problem was that the clones use the opposite logic with CS1 and CS2 than KS0108 maybe because they are clones so that's why there are two firmwares for these displays S6B0108 and KS0108 (both identical except for CS1 and CS2), I'm very glad you made it work at the end

[ArchibaldSTM]

Works! I flashed the firmware that you said. God... I never would have guessed in my life that this was the case... Roderico, I take off my hat and my respect! Thank you all, now I will make out in the case. P.S. Both displays work

[roderico]

Hello Roderico! Everything is fine with jumpers --- checked with a tester. The PCB is also normal (I checked everything several times). To exclude the display, connected the second. He has a 100% controller KS0108. However, nothing has changed, everything is the same. Maybe it was necessary to put a tick in front of the MCLR item in PICkit3?? I bought PIC18F25K22 in a trusted store. Just in case, I connected the first display to the DM-1 ... everything works. In general, I will continue to think ...
The second display bought in this store

for display 12864-2 you need VDI_S6B0108_P18F25K22.hex firmware, for display 12864TXD v1.0 try both firmwares S6B0108 and KS0108, you also need to reduce the contrast to see something in the display, in the image you posted it looks like it is at maximum and with that contrast you would not be able to see if it works or not
