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 1145d 23h /System09/trunk/rtl
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 1146d 01h /System09/trunk/rtl
208 swapped 32k and 16k ram to use block_spram. davidgb 1190d 01h /System09/trunk/rtl
207 Updated design to pick up vdu8_spram (which uses parameterized ram for video memory instead of hard macros) davidgb 1190d 02h /System09/trunk/rtl
206 Update comment/cleanup davidgb 1190d 02h /System09/trunk/rtl
205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 1190d 02h /System09/trunk/rtl
204 patched up ram for zybo use davidgb 1190d 02h /System09/trunk/rtl
203 Added a parameterized ram model. davidgb 1190d 02h /System09/trunk/rtl
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 1190d 03h /System09/trunk/rtl
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1196d 22h /System09/trunk/rtl
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1203d 19h /System09/trunk/rtl
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1204d 20h /System09/trunk/rtl
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.		 davidgb 1204d 22h /System09/trunk/rtl
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.		 davidgb 1211d 19h /System09/trunk/rtl
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1211d 19h /System09/trunk/rtl
195 Switched to using the UART over usb for the console port. davidgb 1211d 20h /System09/trunk/rtl
194 Finally have a working board. davidgb 1211d 20h /System09/trunk/rtl
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 1212d 00h /System09/trunk/rtl
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 1212d 00h /System09/trunk/rtl
189 Remove unused file. Created by ISE gui. davidgb 1218d 15h /System09/trunk/rtl
188 update options to match what the ISE gui does davidgb 1218d 15h /System09/trunk/rtl
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1218d 20h /System09/trunk/rtl
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1218d 23h /System09/trunk/rtl
185 Reverted back to the single-step version - something was broken davidgb 1219d 00h /System09/trunk/rtl
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1219d 02h /System09/trunk/rtl
179 Zybo port done to the same point as the Atlys port. The hardware appears to work but the ACIA is not communicating properly. davidgb 1219d 02h /System09/trunk/rtl
178 work on constraints file davidgb 1219d 13h /System09/trunk/rtl
177 work on zybo port davidgb 1219d 13h /System09/trunk/rtl
176 Don't delete system09_impact.cmd on 'clean' davidgb 1219d 15h /System09/trunk/rtl
175 Corrected RS-232 pin connections. Cleaned up code. Removed debug code.
System boots but the baud clock must be wrong - get garbage on hyperterm.		 davidgb 1219d 15h /System09/trunk/rtl
