223 -- 0.3 David Burnette 8 April 2021 Added read-back of clk/transfer size
-- as well as a debug tag to confirm
-- read operation
davidgb 663d 10h /System09
222 Added SPI master to project. Pick up Atlys rom davidgb 663d 10h /System09
221 Completed Atlys option davidgb 663d 10h /System09
220 checkin davidgb 663d 10h /System09
219 back out last change davidgb 663d 15h /System09
218 Added ROM variation for Digilent Atlys board davidgb 663d 16h /System09
217 Extended debug sw to show keyboard data. PS/2 keyboard now works on USB HID (you must use a PS/2 keyboard + PS/2-to-USB dongle for it to work). davidgb 666d 14h /System09
216 Get rid of warning about unconnected CLK0 pin davidgb 666d 14h /System09
215 Update project after switching to xilinx block ram davidgb 666d 17h /System09
214 Switch to Xilinx block ram davidgb 666d 17h /System09
213 updated project file davidgb 666d 17h /System09
212 Switched from VGA output to HDMI output. davidgb 666d 17h /System09
211 New version of VDU8 that has HDMI output. Still needs work refactoring clock signals. davidgb 666d 17h /System09
210 Check in code fragment implementing HDMI/TMDS encoding.
Derived from HDMI_test.v (c) & KNJN LLC 2013
davidgb 666d 17h /System09
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 666d 19h /System09
208 swapped 32k and 16k ram to use block_spram. davidgb 710d 20h /System09
207 Updated design to pick up vdu8_spram (which uses parameterized ram for video memory instead of hard macros) davidgb 710d 21h /System09
206 Update comment/cleanup davidgb 710d 21h /System09
205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 710d 21h /System09
204 patched up ram for zybo use davidgb 710d 21h /System09
203 Added a parameterized ram model. davidgb 710d 21h /System09
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 710d 22h /System09
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 717d 16h /System09
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 724d 14h /System09
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 725d 15h /System09
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 725d 17h /System09
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 732d 14h /System09
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 732d 14h /System09
195 Switched to using the UART over usb for the console port. davidgb 732d 15h /System09
194 Finally have a working board. davidgb 732d 15h /System09
