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

[Mdtoday]

Hi Md
Yes I live in Sydney Australia.

Dean, if you have trouble with the AliExpress parts drop me your postal address on PM and I'll send you one.
We will need most of what we have for our prototyping but happy to help out for your proto board.

Cheers

MAGPI V4 - Bipolar Nfet ?

how about 1.5 amp peak to peak bipolar with 1.2 microsecond risetimes and 650 volt flybacks ?? ... for starters.

We look forward to it .
Thank you so much .

Hi Md,
Thats is really appreciated and will definitely take you up on the offer if the Alliexpress chips turn into duds.

Great result Moodz.

Looking at the original schematic.

Change R11 and R16 to 5.6 mH neosid or similiar inductors.
Change c9 and c16 to 10uF electrolytic.

Change R13 to 100k
Change R14 to 100k

Change C4 to 1uF
Change C5 to 1uF

Result = supersmooth audio tone :-)

Easily drives a 4 ohm speaker to 250 mW at full volume ( ... approx ) with V1.2 firmware

Hi Paul,

I have done these changes and grounded the 7805 and as you say smooths out the audio with V1.2 code but when using the V1.3 code it all falls apart sensitivity down encoder very scratchy its as though there is a loose wire somewhere but that is not the case at first I thought the code was corrupt so I reprogramed it and no change so I have reverted back to V1.2 for now.

Regards, Ian.

Hmmm ... OK I will check that out .. thanks Ian.

Hi Moodz,
Trying to compile V1.2 but it appears I am missing some system files <peripheral/bmx.h> <peripheral/adc10.h>
My make files directory is C:\Program Files\Microchip\xc32\v4.21\pic32mx\include\pic32m-libs
My MPLAB X IDE is V6.00
Below is screen shot of the default compilers.
Also it appears that my 20 x 4 character display is using Hitachi HD44780 controller so will likely need to re-write the driver.

Attached is v1.3 source.

The C compiler must be v2.15 to support PLIB functions.

You have to install PLIB after installing the compiler.

The IDE I use is version 6.05

Not sure why you have to rewrite the driver ... the library IS for the HD44780 controller and it works fine.

Hi Moodz,
Thank you for your help.
I have installed the V2.15 toolchain onto my V6.00 IDE essentially it looks exactly as per your screen shot same Pack version etc.
There is only one file missing when I try to compile and that is bmx.h..?
The directory I installed the V2.15 toolchain is from the link below "PIC32 Legacy Peripheral Libraries"

From what I can see ... the bmx.h file is provided by older versions of the XC32 compiler ( so its a microchip file not mine ).
I am not on my regular machine here .but I do have V1.4 installed here and the bmx.h file is sitting in C:\Program Files (x86)\Microchip\xc32\v1.40\pic32-libs\include\peripheral

here it is anyway ...

Hi Moodz,
I managed to install the peripherals library >>> C:\Program Files (x86)\Microchip\xc32\v1.40\pic32-libs\include\peripheral
Lots of warnings when compiling such as >>> #warning The PLIB functions and macros in this file will be removed from the MPLAB XC32 C/C++ Compiler in future releases
There are only the below 2 issues I need to figure out which I hope when sorted will be able to compile.

The V1.3 source project I posted last was set for a MX250 device .... your error message is saying you have it set to a MX150 device ??

Hi Moodz,
Thats because I am using an MX150.....?

... OK looking at that log there is some error not visible ... should be listed higher up in the log.
