Description: Sinclair ZX spectrum48 emulator on stm32f103c8t6 & ILI9341 SPI display

Installation on ubuntu:

• git clone https://github.com/sdima1357/specci48
• cd specci48
• make
• .. connect hardware
• ./load.sh

Status:

Work in progress… Right now only proof of concept

today i have recieved new blue pill board .
Seems that not every board the same , part of them 64K
Older board (same price) was have 128K flash

On ili9341 board You must close(short) jumper J1 to 3.3v .Check board documentation… 5 volt can damage your stm32
Touch,Display and SD card use common (3 wire CLK,MISO,MOSI) SPI1 interface. Chip selects are different.

2. started from here:
   gorien for stm32f4 (last version very simular to fuse,same macros)
   http://forum.easyelectronics.ru/viewtopic.php?f=35&t=16592&start=150

3. most tricks from here, but simplified & reduced and added partially instruction decoding:
   fuse (http://fuse-emulator.sourceforge.net/)

4. baseline display routines from:

5. touch from here,completely rewritten calibration by LS 6 points:
