We are in the oil industry for instruments, 51 have been used, and the lattice, recently led to do algorithm to convert aLTEra, certainly have to write my late microcontroller, at the same time let me pay more attention to nIOS and FPGA data communication, see if video discovered nIOS structures, methods of MCU library functions must have to write ah, their level is limited, also didn't do any arm, has been written in way of register before 51 single chip microcomputer, feeling really good study library function to use aLTEra version, more than 30 years old is a bit difficult, after all, we still have a lot of other things to do ~ ~ please god what can write programs in the nIOS as 51 to write? Is not considered in altera replacement lattice when the fpga using calculate, microcontroller is not changed
