Navicat Posted January 20, 2015 Report Share Posted January 20, 2015 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??

TK. Posted January 20, 2015 Report Share Posted January 20, 2015 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 Best Regards, Thorsten.

Navicat Posted January 21, 2015 Author Report Share Posted January 21, 2015 Thanks for your reply Thorsten First of all STM32F4 can support those lcd's.. i 'm just asking the pinning :) 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 :D ) 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. Best Regards, Tilemachos. Quote Link to comment Share on other sites More sharing options...
latigid on Posted January 21, 2015 Report Share Posted January 21, 2015 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. Quote Link to comment Share on other sites More sharing options...
Navicat Posted January 21, 2015 Author Report Share Posted January 21, 2015 (edited) 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??

Shuriken Posted January 21, 2015 Report Share Posted January 21, 2015 J16 would be my guess too. You will want SPI with DMA. Quote Link to comment Share on other sites More sharing options...
Navicat Posted January 21, 2015 Author Report Share Posted January 21, 2015 (edited) 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!
