(Tim) Efthimis Kritikos 1966ab78b4 Peripherals/I2C: Added a CPU I2C driver and wrote a bootloader that uses that to boot from an I2C eeprom ... I'm happy to have reached 200 commits and with this, version v0.3.0 is functionally ready. I still need to do a fair bit of cleanup and bug fixing though before the actual release. With this commit I added a CPU I2C driver as well as a basic arbiter to have the hardware lcd controller and the software i2c communication pass through the same I2C driver and I2C bus. I also wrote a bootloader that reads code from an i2c eeprom to make sure the hardware works.		2024-02-09 23:30:58 +00:00

ascii_to_HD44780_driver.v	Project: The cpu finally works perfectly now even at full speed as far as i can tell! I made the ram and register writes synchronous which fixed the weird issues I had, then I added -abc9 to yosys so that nextpnr can actually route the cpu at full speed and increased the display fifo since the cpu is so fast now!!	2023-11-15 18:43:56 +00:00
