205	A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory.	davidgb	1153d 03h	/
204	patched up ram for zybo use	davidgb	1153d 03h	/
203	Added a parameterized ram model.	davidgb	1153d 03h	/
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	1153d 04h	/
201	A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake.	davidgb	1159d 23h	/
200	Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port.	davidgb	1166d 20h	/
199	Add in full RS-232 handshake for PmodUSBUART.	davidgb	1167d 22h	/
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	1167d 23h	/
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	1174d 20h	/
196	Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm.	davidgb	1174d 20h	/
195	Switched to using the UART over usb for the console port.	davidgb	1174d 21h	/
194	Finally have a working board.	davidgb	1174d 21h	/
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	1175d 01h	/
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	1175d 01h	/
191	check in file so that you do not need to generate it when running ISE in gui	davidgb	1175d 22h	/
190	check in file so that you do not need to generate it when running ISE in gui	davidgb	1175d 22h	/
189	Remove unused file. Created by ISE gui.	davidgb	1181d 16h	/
188	update options to match what the ISE gui does	davidgb	1181d 16h	/
187	Partially works. Garbage on the ACIA due to baud clock problems.	davidgb	1181d 21h	/
186	Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps	davidgb	1182d 00h	/
