I've used some of these before. And for less than $3.00; it'll save me like 20 hours researching parts and designing my own custom PCB. I just need to cut the appropriate traces and put this in between. I was thinking of essentially making my own with transistors but this works also.

Hi Guys,

Sparkfun has some nice inexpensive level shifting boards,

Nice post, it looks like you are well on your way to exploiting the FPGA.

You'll get the best result by doing a complete new board for the robot but that will involve you in work you may not want to take on.

It will let you experiment using the FPGA to do all the low level control - which is good.

To drive the robot board from the Zynq will mean spoiling it by quite a lot of hacking (remove processor, graft in level shifters)

Just talking to the robot AVR via SPI is not really giving the Zynq anything to do - just using it with a bog standard peripheral to do some processing.

The best work:benefit ratio seems to be the middle option, if you don't mind hacking the robot board.

To add an ADC - do just that - the Zynq can control an ADC standing on its head (ie easily) and it's a good project to get going on FPGA.

Hi James,

Thank you for your interesting blog. I've used Vivado for the Arty S7 Roadtest and there was much I didn't get to understand - I'm hoping to learn more reading the PathToProgrammable blogs like yours.

Regarding your line following bot - I did a search looking for a shield that converts 5v/3.3v logic but couldn't find one. Personally I would try and make my own (using a bare UNO development PCB) and some bidirectional logic translators ( range of bi-directional logic translators from TI ). You could use your new board to interface your Zedboard to other 5v boards in the future.

Good luck on your path(s)
