Hi,
sorry, I've digressed too much...
Yes, Norbim's solution is probably the best way for me... to get a working PFM2.

Tks again for your kindly help,

regards,

Salvo

Hi Salvo,

Sorry for the late answer. I'm sure any standard 20*4 LCD works with my code. At first my OLED didn't work properly, so I made some timing change to better follow the datasheet. Later it turned out, that the problem was with the supply voltage instead.
I'm really happy with the audio quality of the Discovery. In one of my projects I use an external I2S board with a Discovery, because I need audio input too. The onboard codec have way less noise than the external one. I think STMicro made a really good job with the F4Discovery board.

Thank You Thierry, I use this box design for my other small projects too. The wooden sides are made from bamboo cutting board.

Regards Norbim

Hi Thierry,

yes there is no hardware volume control, but I implemented midi CC 7, so you can control it via midi.
The knobs are form MidiBox forum group buy. AFAIK last batch was a year ago:

Hi Thierry,
first check the original STMicroelectronics product page to know the orginal version:

I bought all my Discovery boards from Farnell (farnell.com). The part number is STM32F407G-DISC1.

Hi,
Here is the latest compiled fw.
Norbim

Hi,

I finally got my Discovery Board.

I'm doing my own "motherboard" pcb for the encoders, lcd and switchs...

How can I upload Your bootloader and firmware using the on-board USB connections?

I'm a newbie... ::)

Use the STM32 ST-LINK utility via the mini USB on the debugger side of the board.

Finally got mine working!!

Thank you Norbim!

Thank you Xavier!

I hope to upload soon, on my website, some other info on how I built it.
I made my own "motherboard" pcb to host the stm32discovery board...
The total cost has been kept low!  ;)
