Im interested in low cost FPGAs, like around the $5 range. My goal is to make a closed loop stepper microcontroller.
Ive never did FPGA design. what's good resources to start reading to get caught up with the basics? Figure I should ask those more in the know.. :)
- 01100011 8y agoStart with digital logic fundamentals(not, or, and, xor, xnor gates, flip-flops(d, jk, etc). It helps to know some analog theory so you understand propagation delay and such. Then you'll probably want to learn a language like Verilog or VHDL. From my experience, most people like Verilog and VHDL is mostly used in the defense industry. You could probably skip right to Verilog/VHDL, but I really suggest having a background in digital logic. FWIW, I'm just an embedded software guy. I came from an EE background but it's been a long time since I've played with programmable logic.
- sigstoat 8y agoif practicality is a concern at all, then you can get stm32's for about that which will have significantly more power than you'll be able to cram into a $5 FPGA, and the development environment will actually be pleasant. (or just buy them, there's at least one on crowd supply, another was on kickstarter in the last couple years, etc)
