Hi Squonk42,
your post is really very interesting! I found some confirmations to some my "thoughts" about PCB design...
Thanks a lot for sharing! :D

Re: IceStamp FPGA Board in DIL28

For that price you can get only the FPGA chip (from Digikey) :shock:

Re: CPLD Fun Board (Arduino STM32 + Altera CPLD)

Thanks Pito!

About the EMP570... I found it at about 3.5$ (it's on the way...)... anyway you are right... it is a bit pricey considering that an entry level FPGA can be found at about 5$ (but you must add the eeprom and "some" regulators too...)

Re: CPLD Fun Board (Arduino STM32 + Altera CPLD)

Thanks! Not for now, but next days/weeks I want add some basic VHDL examples here with some examples using the Quartus II schematic editor, using the HW on the board. But at first I must add how to configure the Quartus II IDE at best for the board... PS: please don't consider me a VHDL expert... :l...

CPLD Fun Board (Arduino STM32 + Altera CPLD)

Hi all, as "promised" here it is the CPLD Fun Board! :D It can be seen as two boards into one: a STM32F103 based Arduino (Maple Mini compatible) and an Altera MAX II CPLD (EPM240T100 or EPM570T100) dev board to start playing with VHDL/Verilog, or just to try to use a CPLD with the Quartus II schemat...
