Computer-generated dream world: Virtual reality for a 286 processor
We set the data bus to write mode, put the NOP instruction on it, send a clock signal, then set the data bus back to read mode.
Which we then do with the code generated by nasm :MEMORY = Memory() MEMORY.load( 0x000500 , [ 0x31 , 0xc0 , 0x8e , 0xd8 , 0xa1 , 0x0f , 0x05 , 0x03 , 0x06 , 0x11 , 0x05 , 0xa3 , 0x13 , 0x05 , 0xf4 , 0x34 , 0x12 , 0x0a , 0x00 , 0x00 , 0x00 ]) MEMORY.load( 0xfffff0 , [ 0xea , 0x00 , 0x05 , 0x00 , 0x00 ])All that remains is to handle the cases.
In our case, 'Memory data read' is very similar to 'Memory instruction read', so we can handle both with the same code.
In what order should we place the bytes onto the data bus?
The GPIOA register represents the least signific…
