  1. I am having layers of problems with the Pmod MicroSD. My ultimate goal is to get through the wifi example on youtube with a Basys 3. Today I am just trying to do the "hello world" demo for the micro SD Pmod. Issues: [Common 17-69] Command failed: BOARD_PART_PIN cannot be assigned to more than one port ["f:/microSD.srcs/sources_1/bd/microSD_bd/ip/microSD_bd_PmodSD_0_0/microSD_bd_PmodSD_0_0_board.xdc":7] I get this error for 4 pins set_property BOARD_PIN {JB7} [get_ports Pmod_out_pin7_t] set_property BOARD_PIN {JB8} [get_ports Pmod_out_pin8_t] set_property BOAR
  2. Tells me PmodWIFI is packaged with board value arty and to update my basys3 to the arty. I am confused. Well hang on a second. It finished generating a bitstream and I see no critical warnings in the project summary. In fact if I tell vivado to discard user generated messages in the messages window, the project has no indication of critical warnings at all. Still confused but closer to my goal.
  3. I am new in VHDL and have a school project. I am reading 40-bit data from DHT11 humidity sensor. Although first 8 bit is meaningful to me, I read all 40. At the end of the transaction, it is required to light 8 LEDs corresponding to each bit of 8bit. I can light the confirmation LED which lights when all 40-bit data is received. But, can’t do it for the data LEDs. I need urgent help. Thanks.
  4. Hi, I created a VHDL description to work with the PS2 interface of a Nexys-3 board, but I'm having a problem with the arrow keys. The right arrow key - code E0 74 - works perfectly, but strangely the other three - codes E0 75, E0 6B and E0 72 - do not! I tested with the Ctrl key - code E0 14 - and with the Alt GR - code E0 11 - and they also work perfectly. Since I was unable to understand the problem, I tried with another board - a Basys-3 - and with Vivado. The behavior was exactly the same. Then I picked up an old Spartan-3E board with a true PS2 connector and the whole arrow keys and
