4.3" TFT LCD on Seqv4

Design Concepts
1

Hello..

I am building a project based on the MBHP_CORE_STM32F4

 

I wanna add a 4.3" TFT LCD and the module i will use is this : http://www.4dsystems.com.au/product/4DLCD_FT843/

 

There is a 10 pin out from the screen.

Here is the datasheet : http://www.4dsystems.com.au/productpages/4DLCD-FT843/downloads/FT843-4.3-Display_datasheet_R_1_2.pdf

 

Here is the pin out :

 

PIN                SYMBOL

 

1  ------->        3.3V

2  ------->        SCK

3  ------->       MISO

4  ------->       MOSI

5  ------->        CS

6  ------->        INT

7  ------->        PD

8  ------->  AUDIO_SHDN ----> Audio shut down ( dont know if i need it )

9  ------->  AUDIO_OUT   ----> Audio Out ( dont know if i need it )

10 ------->     GND

 

Any help on how too connect the pin out on the STM32F4Discovery pin out??

This display won’t work because:

  • it isn’t supported by MIOS32

  • graphical LCDs are not supported by the MBSEQ V4 application

  • the screen dimensions are not supported by the MBSEQ V4 application

  • the 80x2 character row would be hard to read with this small size

-> bad choice

Thanks for your reply Thorsten

 

First of all STM32F4 can support those lcd’s.. i 'm just asking the pinning :slight_smile:

 

I’m making a clone of TR-808 and i wanna use your amazing Midibox Sequencer. I will not use the old MB808 seq… My design started from the begin and here is my concept :

 

  1. TR-808 Voice Boards designed from the begin with SMD compoments wich means smaller and cheaper pcb. ( I have my own DIY SMD oven :smiley: )

  2. Midi Interface wich means you can have different Accent(Velocity) for each instrument from a digital sequencer like midibox.

  3. More voices than the original TR-808. ( I ll add Guiro and maybe some extra snare drums and also i am planning too add some 909 voices.)

  4. Cymbal / Hi Hat / Hand Clap / Maracas / Snare Drum alternative noise inputs from front panel with patchcables. Alternatives sounds will be : Original Pink/White noise from 808 circuit or a 909 circuit or any other noise source,even a microphone.

There will be many future adds that i am currently working on..

 

 

I want to use the midibox seqv4 but i wanna make a different version with GUI and real buttons. ( Midibox DR and MB seqv4 is not enough for me) I need to make a module that will help me make my dream come true and give some ideas so the midibox sequencer project go further.

 

Here some pictures from my work on TR-808 voiceboard cloning in Altium Designer.

Maybe the STM32F4 supports the LCD, but probably not the specific MIOS application. You would have to arrange your own pin mapping and build a custom firmware.

Yes i figured it out.. I 'm under datasheet reading now.. I think will be not a problem to make an lcd driver and mios compatible..

Excuse me for my bad English if you guys see any mistakes!

 

:smile:)

 

EDIT :

 

What about using the J16 on MBHP_CORE_STM32 for wiring this lcd??

I will make drivers from the begin and i will make it mios32 compatible..

What you think it is possible??

J16 would be my guess too. You will want SPI with DMA.

Already under construction :smile:)

Here is the schematics i started!

 

 

I just purshaced the an STM32F4 and the LCD from 4D Systems.. Can’t wait to start.

Thanks for your attention and your answers everyone!
