  1. Dear Dan & Bianca, Thanks for showing the place in schematic. I see that LED , SwBttons & VGA are connected to the same bank. If I change the voltage to 1.8v for bank 14 ,then the other LEDs, VGA's will work ?? Having second thought to use the level shifter as suggested by dan, is that level shifter is bidirectional ? http://store.digilentinc.com/pmod-lvlshft-logic-level-shifter/ kindly advise. Thanks and Regards Lakshman.
  2. Dear Dan, Thank you for the prompt reply. I understood that we need to change the Voltage in the Bank from the link https://www.xilinx.com/support/answers/57045.html . But even I change in the constraint file still we need to change it in the Basys3 board. From your reply I understood that we need to desolder it & solder it to appropriate wire. I went through the schematic I didn't find any 1.8v but we have 2.5v , 3.3v & 1.5v. So I need to give external voltage of 1.8V ? if so which wire I need to desolder in bank 14 or bank 15. will you please point it to me ? Regarding the level shifter, if I am not wrong its a bidirectional levelshitfer (1.8v to 3.3v & 3.3v to 1.8v) am I right ? kindly advise. Thanks and Regards Lakshman.
  3. Hi, recently I bought basys3 board from diligent. In my project I need to use 3 GPIO's both input & Output at 1.8V.Kindly suggest me what I need to change? As from the website , I know I need to change in the constraint file(XDC).bank 14 pins & set CFGBVS = GND. https://www.xilinx.com/support/answers/57045.html do I need to change anything in the board.
