VDI-RODERICO

[nikko10]

Hello Rodericо! I connected an indicator with 10 LEDs to the MD Whites board: X to pin 8, Y to pin 7 of LF347, rebuilt from BG.1 ferrite and 2 LEDs do not light up, a group of 5 LEDs 3,4,5,6,7 lights up, alternate with the last SVD, tried adjusting 5k and foil - no result. What about pliers, what about a brass coin, near the sensor, the last SVD lights up, I raise the target higher, these 5 LEDs light up. In general, it does not distinguish between metals, it is not regulated. - to put the control buttons on this indicator or are they not needed there?

I connected one more circuit to PIC18F25K22 and MCP602, check-VDI LED MCP602.rar

[QUOTE = reiv; 229863] Здравствуйте, интересная ветка. Вот печатная плата с регулировкой подсветки. Я предполагаю, что VDI Родерико не имеет этой функции?

And you can see the diagram for your board. Or at least the denominations of the parts. Many thanks.

Hello! I read the entire forum, but please clarify. Do I need a crystal oscillator when using controller PIC18F26K22? Thanks!

The Source code will tell you if it needs a XTAL. Look at the CONFIGURATION words for XTAL or Internal oscillator.

[ArchibaldSTM]

I understood. This is done in the program when programming the controller. Thanks

[nikko10]

roderico, there were defective microcircuits with Ali Express SSOP28, I will get good ones and then I will check again the firmware for the LEDs. Sorry for the panic

Zolen display with16pins

Hello ewery one I am new in this :-(
I programed pic P18F26k22 with VDI_ST7567_P18F26K22_RR40.hex file
From ebay I received zolen display with 16 pins,
how i can connect this display on pcb Vdi-pcb v2. 2
Is it possible without change source code?

Match the pin NAMES and connect.
One problem I see: The 2.2 schematic calls for a R/W signal whereas the display you have have separate /WR & /RD signals.
The "ST7567.c & 18f25k22.h files do use the /WR & /RD signals. So you need to READ the source code files for the pin definitions.

The VDI source (and hex) has options for a variety of display controllers. Look in the source code files for pin definitions.
The "ST7567.c & 18f25k22.h files do use the /WR & /RD signals.
Example:
ST7567_nWR = 0; // is used in ST7567.c
#define ST7567_nWR GLCD_RW // in 18f25k22.h file is defined to connect the RW pin.

simple as that...

Thanks a lot Valtr :-). It's much clearer to me now.

Hi Waltr I have a problem with my VDI module. I connected the Zolen display to the PCB as follows: 1-8 on data port, RD-RA5, WR-RC4, D / I-RC5, REST-RC6, CS-RC7, VDD- + 5V, VSS-GND, A + on the pcb A+. But the display remains black. The hex code is loaded correctly ВДИ_СТ7567_П18Ф26К22_РР40. Am I wrong somewhere?

[Altra]

Is the display black or blank? I use these displays and the contrast is controlled by the firmware. So if black you need to lower the contrast. If blank (gray) you need to increase it. Assuming your wiring is correct. Do you have a link to the code you are using?

[zmaj od nocaja]

Pozz Altra. The display remains blank and does not turn on the backlight. How do I increase the contrast? By the way, the hex code is from 21 pages of this forum for pic18f26k22

[Altra]

Sorry I don't understand. The Hex files can not be modified. You would have to make changes to the src files in C to to change the contrast.


Ok the text is now translated. You need to find the C source code, it is located back a few pages. I am not set up to help you maybe Roderico or Walter can guide you.

Also there are jumper connections on the zolen for serial or parallel and 80/68 style addressing. Check that the "80"and "P" jumpers are soldered
