09ccce5f30 Peripherals/HD44780: Rewrote and cleaned up a lot of the driver code. Unfortunately what i think is a very weird bug in yosys is still affecting the codebase 2023-11-15 00:26:46 +00:00
2c8e8a9d9c Added simple support for \n and \r on the HD44780 driver, increased the synthesised mem to fit brainfuck_compiled.asm and made it the default. 2023-11-12 21:39:27 +00:00
7d2cb5672f Reduced numbers to be sorted in gnome_sort.asm to fit in lcd, fixed hlt on real hardware, slowed down cpu, increased lcd fifo and with that I almost got gnome_sort.asm working perfectly on real hardware 2023-11-12 07:31:05 +00:00
a88c420ca5 Added an I2C driver, a PCF8574 driver and an HD44780 display driver. Unfortunately this shows that even fibonacci doesn't run correctly. Nonetheless, I made colored_led.asm output text to the display! 2023-11-09 22:10:55 +00:00
01dcbfa7a1 The CPU works on real hardware for the first time! I added an adjustment for ram size, added control for a led and a test program for it. On the fpga board there is an actual led there that I used to verify functionality 2023-11-06 08:13:36 +00:00
934e2f5a36 Fixed a bunch of things wrong with fpga_top.v and gated off some more simulation-only code 2023-11-02 23:46:12 +00:00
601397b7f0 Properly added fpga_top.v stuff in the build system and fixed some syntax errors 2023-11-02 22:00:07 +00:00
36bf8f9c7a Added OrangeCrab board-specific code to connect the cpu to the outside world 2023-11-02 20:40:04 +00:00
