VDI-RODERICO

[roderico]

Hello praktik, if we somehow knew what the phase change introduced by the ground is, we could take into account and correct the effect in the vdi, however, I do not know what this phase change is, and I suppose it depends on the type of soil, material, etc., but it would be very good to know, e.g. someone could make some tests with different metals buried/unburied in different soils to quantify the effect...

Hello Roderico! I liked your development of the VDI indicator. Please tell me, how does the change in the phase of the ground regulator affect the accuracy of the VDI readings? Or are these changes negligible? Sincerely.

Yeah follow roderico tips, you will save your time ;D
My PCB for oled display with two MCP602 didn't give what I expected :s
My display stay black ... Roderico can you confirm that my PIC18 is ok if after writing with my pickit3 I have the message "programing complete" in blue ?
I checked VDD it's ok +3.3V for oled, VSS is 0V I used V2.2 for my pic18f26k22 and SSD1305 (8080). All pins are conected except VEE /A+ / K- and V0.
I have no idea of what is wrong PCB seems ok, ICSP work because MPLAB recognise the microchip and write it whithout error message...
If someone have an idea of something to check ....
Good luck nikko10 !!

could you also provide one or two pictures of your pcb where the connections can be seen clearly (along with a link of your display datasheet)?

[roderico]

you can change the screensaver if you use the latest firmware in the display menu -> "theme" entry, there are two options: the battery voltage and the kroman01's idea, I quoted your other question because it might be relevant for others, the easiest way for the splash screen IMO would be to delete the current boot message and write e.g. in bold font your text, otherwise you will need to create a bitmap and a function to display bitmaps, and the size of the bitmap would be 128x64 = 8192 bits = 1MByte of space

Roderico, personal correspondence is therefore called "personal", I myself could write for a general review. But I still do not understand whether it is possible to make changes to the screensaver or not

IMO that has to do more with the display, do you have the datasheet of your display?

Hi nikko I haven't seen the messages until today but it is good news that you have made it work.

Good evening, Roderico! I have assembled the indicator, thank you very much for the work done. Works with Golden Musk perfectly !!! I have a request to you, if the project is open access, my personal request is to make a splash screen on the indicator when you turn on the device: "CYBORG UKRAINE". I wrote to Kroman, he told me to contact you. What is the cost of this firmware? Thanks in advance!

the source code is GPL licensed, i.e. you can redistribute it, modify it, etc. under the terms of the GPL, it is distributed without any warranty, etc, etc, which more or less means you can change it, copy it, improve it, etc. but your derivative work cannot add restrictions and/or should be GPL compatible, and the binary files are subject to Microchip XC8 compiler (free edition) terms and conditions

I also started my board, for testing I put a very small indicator KS0108, the beta 4 kroman firmware works fine on Golden Mask 4, the only thing I don't like is the constant inclusion of the power voltage screen saver

[nikko10]

I apologize, there is an error in the archive above in the indicator board - when filling the polygon, I filled in extra contacts, here is the correct LAY fileindicator VDI LAY_6.rar

[nikko10]

I didn't get an answer ... thanks for the help. Who needs boards in LAY, on 3 LEDs works fine on Mask-4indicator.rar

[nikko10]

Good afternoon, Roderico, I have a small request, can you make a gerbera from this file, filling in with DIP-SMD adapters, to fill in 10x10cm when ordering boards in China?
Power supply B + is plus batteries, and V + V- is + -5v? Is this indicator suitable for Golden Mask-4? ThanksVDI PCB MCP604.rar

RODERICO,Many thanks!
