• Logging over SWO (swo_init, swo_writestr)
• Data cache
• Instruction cache
• SysTick based sys_delay_ms
• 400 MHz system clock (aka sys_go_fast)
• External SDRAM support (32 MiB @ 0x9000_0000)
• GPIO
• Very bad HD44780 driver (not a part of the HAL)
• sys_delay_us
• Interupts
• UART
• I2C
• LTDC

Other TODOs

• Cleanup init code
• Switch to C++ (mostly for syntax, not OOP)
• Make BadHAL a CMake module
