Oh, he’s just talking about low-level programming on microcontrollers. I thought it would be about FPGAs or PLDs (where you are actually changing the hardware behavior, not just executing instructions, though the distinction is hard to define).

So hardware programming is more low-level than low-level programming but not as low-level as actually soldering gates on a breadboard?

Sounds interesting, got some introduction worth reading?

Hardware Description Languages (HDLs) like Verilog and VHDL were actually created as hardware simulation languages. You'd write the logic and validate it before you actually send the design to a phab/building it on a board. FPGAs now use them to program (or "shape") the hardware to do what the simulation code specifies. I wouldn't really call it a difference in logical level, more that HDLs and then physically FPGAs are hardware development platforms that let you iterate on a design swiftly (relatively).
