We will be continuing with adding generics to our vga_solid module. Last class left off with the h_counter, v_counter sizes and, red, green, and blue signal widths being generic. Now we will make the VGA signal timings generic as well as outputting the current x and y positions. Finally, if there is time, we will remove the DCM/PLL from the module and add it to the parent.
For those of you with a Nexys3, Basys2, or Atlys, you will be able to connect a VGA cable directly. For those using a Mojo or some other board without a VGA connection, please E-Mail email@example.com stating that you need a VGA breakout cable! There are several breakout cables from last class, but we need to make sure there are enough on hand.
The slides for the upcoming and previous classes can be found here. The slides are generally made during the three days before a class. An E-Mail will be sent to those attending the class via Google Hangouts with instructions for getting an SRAM chip.
1. Overview of last class
2. Calculate and output x and y positions
3. Make VGA signal timings generic
4. Remove DCM/PLL from vga_solid
If you would like to join the class, then please E-Mail firstname.lastname@example.org. The class is now to a point where you need to know VHDL prior to joining. We also stream the class on Google Hangouts. Please send an E-Mail to email@example.com if you would like to join the Google Hangout.
**IMPORTANT** You *MUST* have ISE (not Vivado!) installed prior to the start of class!!! ISE can take upwards of 30 minutes to an hour to install. We will not have time to wait for ISE to be installed. Please go to here and download the ISE Design Suite package for your operating system. If you have licensing or installation issues, please contact firstname.lastname@example.org
1. FPGA development board with Spartan 3 or Spartan 6
2. USB cable for programming
3. JTAG programmer if your board does not have USB
4. Laptop **with ISE installed** and either wired or wireless network connectivity
5. VGA breakout (red, green, blue, horizontal sync, vertical sync, and ground) if you do not have a VGA connector on your dev board.
1. VGA breakout if you let the instructor know
We have been given ‘academic’ status from Digilent Inc (http://www.digilentinc.com). This means that the instructor can (sometimes) purchase boards from Digilent at the academic price. This discount will only apply to people who are attending the class regularly and is on a case-by-case basis from Digilent.
Since Unallocated Space runs off of donations, we would like to mention that the recommended donation for this class is $5. It is by no means a requirement! Attendance to the space, and this class, is 100% free to all!
