Stm32F4Discovery port

[elea]

Many thanks! I don't know why Eclipse was giving weird errors. I'll try this out tonight and compare it to my FS1r.

Quick question: will this firmware work without an LCD attached?


Here were my errors compiling the boot binary:

I've never tried it without LCD. The control surface works exactly the same way as the original pFM2, I didn't change it.
Related to build errors I'm sorry, but I'm not an expert in it.

[elea]

No problem - I at least have your bootloader and I finally managed to get the rest compiled.

I'll get an LCD to test it.

Thanks again, norbim1.

Hi,
I built a low budget PreenFM (first version) using home made pcb and a maple mini clone, with a cheap 2004 LCD bought fm ebay...It works quite well!
Now I want to start the PreenFM 2 project on a low budget! I don't have the skill to code and compile the firmware...
Your stm32f4 Discovery porting is the best choice for me..
The questions are:
1) Is it possible to use your compiled bin (boot and firmware) using an ordinary (not oled) lcd (20*04)?
2) Once I've uploaded your boot loader to the Discovery board, is it possible to use the official and updated compiled firmware without any change?
2) What about the audio out quality of the Discovery? Could you please post some audio demo?

Thank you very much for your kindly reply!

Hi,

1) I'm almost sure the answer is yes, as there's not reason the low level display code has been changed.
And the preenfm2 works with regular LCD.

2) No. Norbim's firmware uses the DAC of the discovery and different pins for devices.
But i just noticed the firmware is regularly updated on https://github.com/norbim1/preenFM2
Nice job by the way

Thank you very much for your fast reply!
Your synth is fantastic!
Could you please compile them (boot and firmware) for me?
I don't have the necessary skill to do it now.. 

Regards!

[Xavier]

You can start with the zip file from previous page.
It contains the bootlooder 1.11 (latest version) and an old firmware but that will allow you to setup and check your hardware.

I'll try to compile Norbim's latest firmware later.

Let us know how the build goes,

Xavier

Wonderful!

I'll try to begin with the old firmware...waiting for the (compiled) new one!

Many, many thanks!

[norbim1]

Hi,
Here is the latest compiled fw.

Hi,

thank you for the fw!
Can you please confirm, I can use an ordinary LCD 20*04... I read that you did some change on the display driver...
What about the audio quality of The Discovery DAC? Are you happy with it?

Tks again for your help!

To Xavier...

Hi,

I've downloaded and study your schematics...I can't find the one relative to your uC board (FPreen405)?
Does it is open-hardware or not?
What type of minimum system do you use? The one of the CERB40?
Is it possible to have the schematic?
I'm looking to redesign the pcb to embed the uC...or at least to use a smd chip to dip converter and some THT components for resistors, xtal and caps...

Thank a lot for your beautiful project!

Salvo

p.s. in attached "my" PreenFM modular version
 

[Xavier]

I just uploaded the preenF405 schematic here :
https://github.com/Ixox/preenFM2/tree/master/hardware/preenF405

I don't understand your "minimum system" question.


Best,

Xavier

Hi,

fantastic, I've just dwnld the schematics! Thank you so much!

I meant with or without 32khz rtc xtal... as for CERB40 version one or two..

What I'm thinking is to use an lqfp64 to dip converter for the stm32f405 chip and put caps, resistors and xtal near it on a custom board... with the other components: dacs, opamps, conectors and so on.
What do you think, may be work?

Do you use stlink-v2 and the pins "P1" and "jump3" on the main PreenFM2 board to program (at least for the boot-loader) the preenF405 uC?

I made my own "singe side" pcb... to lower the cost for my projects (as I did with the version one of the PreenFM) so I want to try this way for your new project.

Best regards and tks again!

Hello there..
I dont understand much to this thread, but Norbim's box is absolutely beautiful !! Both the box, with the wooden sides, and the knobs..  a very delightful one..
Have a nice week-end..
