Moodz' Awesome Gold Pulse Induction Version 3 - MAGPI V3 Project

[Dean Sarelius]

Hi Dean ... yes I had a look at the rotary wiring and you are right I have wired the C ( common ) to the B switch Good Pickup !
So I changed the wiring to AB and C to common and its still works OK ... so I guess the code and the wiring is foolproof by accident.

I have never used interrupts for rotary encoders ...if you have some other more critical loop task ( like the TX interrupts ) then if the loop is fast enough to sample you get a rotary encoder or multiple REs with very little code overhead plus free debounce.

The less interrupts the better I always say.

Hi Moodz,
Just in the process of re-configuring the V1.4 firmware which I have renamed to V3.11.
Could you remind me which pins you ended up using for the Encoder..?

[moodz]

Hi All,
Everything appears to be working ok.
The issue with the display was the contrast control on the back of the SPI display controller.
Running the display with 3.3V I had to set the contrast control pot to its limit and it is still not very good.
Lucky I provided a 5V backlight option and the contrast is much better.
In order to use the SPI display controller in 5V mode you need to remove two pull up resistors on the SPI controller pictured below labelled R8 and R9.
You also need to add 2 x 4.7k pull up resistors on the main board.
There is a spare header on the main board for the 5V option.
Before I can test with a coil am expecting to receive the surface mount IRFP9640S next week .
in the meantime I will be adding the encoder and testing the audio circuitry over the weekend.
When all this is done and dusted will start a new thread where I will post all the files.

good job

Hi Paul finally got V1.4 programmed first came up with no voltage to VDD then wrong target ID but after 12 goes it finally programmed any way after playing for a while I have some suggestions can you separate threshold volume from target volume because as it is now if you set the volume to a steady low threshold volume the volume of small targets in fact all targets at the lower limits of detection are not loud enough to hear also could you give us a list of what the Menu items are and what they do Volume, Tone, Battery and balance are probably self explanatory it is the other items and their inter relations with that knowledge I would be happier playing around with the settings sorry to be a pain.

Regards, Ian.

errmmm ... the last version 1.4 I left some test timings in there ... I will need to re-release it ... It wont break the detector but the TX is wrong.

Hi Dean ... I downloaded the source zipfile I posted earlier and it compiles fine on a new machine setup ( defaults - did not change any configs ).

the command line option is -g .... see below. ( default setting )

I notice that your generated command line for the compiler is referring to v1.4 XC32 .... you need version 2.15.

I install version 2.15 XC32 then install the legacy PLIB on that ( it should ask you to specify the location of the compiler during install )

Also note that Microchip refer to PLIB for later support libs ( like Harmony etc ) ... this is WRONG. You need the legacy PLIB installer. ( login to Microchip and access the PLIB in the legacy file area )

moodz

Hi Moodz,
Great news..after installing the legacy peripheral libraries into the V2.15 libraries path it succesfully compiled and downloaded to the PIC.
This verfies the fact that the display is not initialising properly as this was the same behaviour I was seeing from the hex file also.
Thanks again for all your help and will let you know when I have it working.
Cheers

Paul ,

Have you done the version V1.4 for the PIC32MX250 yet if so I will try that and see how I get on.

Hi Moodz,
I am still unable to compile fully and I think it is because I am missing some arguments in my compiler setup.
Here is a copy of my compiler output below and when you compare it to yours I can see that you have additional -g -x c -c
"C:\Program Files (x86)\Microchip\xc32\v2.15\bin\xc32-gcc.exe" -mprocessor=32MX150F128B -o dist/default/production/MAGPI008_2023_06_07_V1.4_RELEASE.X.production.elf

Would you know how to setup these arguements in the compiler..?

I have been playing around with the Compiler options fields and checking the Generated Command Line to see if I can get it to match but without any luck..?

I have finished with the assembly of this project and carried out the first tests and it seems to work well, however I have a big doubt with the D3 diode (BYV79-200) since mouser sent me a TO220 assembly diode instead of the one I see in your photos that looks like a diode with DO41 packaging. What diode are you using in your project?

Dario

Hey Dario ... good work ... try a MUR160 diode.

[darov922]

...the case fitted with a handmade 18650 battery pack ( 2 cells in series - 8.4 volts ) which is good for hours of detecting joy @ 230 mA draw.

I am just figuring out if I can make a QADCC ( quick and dirty charging function) with some spare ports on the CPU.

Hey Dean ...

Just to make sure on a clean machine ...

I loaded up a clean Ubuntu 22.04 virtual machine hosted on Virtualbox .

Installed MPLABX 6.10
Installed XC32 v2.15
Installed PLIB legacy on the compiler location.

Downloaded the V1.3 I posted ... and it did not compile .

So there is something wrong with that source package ... it only builds on my workstation ( regular machine ).

I then downloaded the MX150 package from post #16 ....

That builds OK.

In summary ... something IS wrong with the V1.3 package. dont use it till I investigate it.

moodz.

Thanks Moodz,
Really appreciate your help.
Will let you know how I go with V1.2.
Cheers
