Finally forked a BASIC interpreter to use on my Teensy 3.6 Support for : - SDCard - HID USB Keyboard - LCD (128x64) - Buzzer (w/ 2 own audio file formats) - 3 colored LEDs & 3 user btns - HC06 Bluetooth to serial - RPI0W for HDMI output - a specific bus to deal w/ some function boards
I reconnected my rpi0w to the system, for HDMI output (@ this time it does VGAT emulation) may soon I'll make a simple GUI instead (with simple feedbacks as it is now connected on a dedicated Serial port & no more on same port as Keyboard !)
Hi, today I nearly achived the Simple VGAText Serial ouput (100x50 chars - text ONLY interface) replacement by re-using a Raspberry PI Zero + Java + FrameBuffer.
It does actually run an emulation of the VGAText micro-code (receiving text & escaped commands from the Serial Port) to make a Pseudo text-based UI.
It boots & start the program in 14sec from strict powering up time (8sec from linux starts booting).
The cons : It does not starts instantanatly,
the pros : It can be use on ANY HDMI TV or Computer Monitor even with too high resolution, later it will be able to receive some GFX commmands, the render code is (on-board) modifiable, Keyboard reading will replace the HobbyTronics USB Host (keyb preprogrammed) board, & it costs nearly as same as HobbyTronics VGA TEXT board...
I know, It could replace the whole system, but I keep my MCU (teensy3.6) board to do the main Unit... (just for personal fun ! )
