211 New version of VDU8 that has HDMI output. Still needs work refactoring clock signals. davidgb 671d 20h /
210 Check in code fragment implementing HDMI/TMDS encoding.
Derived from HDMI_test.v https://www.fpga4fun.com/HDMI.html (c) fpga4fun.com & KNJN LLC 2013
davidgb 671d 20h /
209 Started adding in keyboard (not tested).
Added in green-only VGA output thru Pmod port to PmodVGA J2 port.
Started working on HDMI output
davidgb 671d 22h /
208 swapped 32k and 16k ram to use block_spram. davidgb 715d 23h /
207 Updated design to pick up vdu8_spram (which uses parameterized ram for video memory instead of hard macros) davidgb 715d 23h /
206 Update comment/cleanup davidgb 715d 23h /
205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 716d 00h /
204 patched up ram for zybo use davidgb 716d 00h /
203 Added a parameterized ram model. davidgb 716d 00h /
202 Updated Zybo design to reintroduce VDU8 driving the PmodVGA on pmod connectors JC+JD.
This version also uses PmodUSBUART on JE. To use PmodRS232 you must edit the .ucf file and select the appropriate pin LOCs.
davidgb 716d 01h /
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 722d 19h /
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 729d 16h /
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 730d 18h /
198 Update UCF file to select Pmod pinout compatible with the PmodUSBUART.
To use, make sure PmodUSBUART has JP1 as "LCL". Connect the usb to the uart and open the terminal program. Test the transmission via the LED on the Pmod. Then (carefully) plug into Pmod port on Zybo.

197 Updates from John Kent:
-- 4.5 John Kent 2012-02-04 Re-arranged Rx & Tx Baud clock edge detect.
-- 4.6 John Kent 3021-01-30 Double sample RxC, TxC, and RxD with cpu_clk
-- for 125MHz Clock on Zybo Z7 board.

196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 737d 16h /
195 Switched to using the UART over usb for the console port. davidgb 737d 17h /
194 Finally have a working board. davidgb 737d 17h /
193 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. Also fixed the 32k addressing davidgb 737d 21h /
192 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. davidgb 737d 21h /
191 check in file so that you do not need to generate it when running ISE in gui davidgb 738d 18h /
190 check in file so that you do not need to generate it when running ISE in gui davidgb 738d 18h /
189 Remove unused file. Created by ISE gui. davidgb 744d 12h /
188 update options to match what the ISE gui does davidgb 744d 12h /
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 744d 17h /
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 744d 20h /
185 Reverted back to the single-step version - something was broken davidgb 744d 22h /
184 update files to correctly produce flex9ram.vhd davidgb 744d 22h /
183 update file extensions davidgb 744d 22h /
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 744d 22h /
