my project must use both GLCD and character LCD. But those signals are common. I don't know how to correct it. Can I add in my SOPC a tristate to correct them ? How it design ?
I'm done on the system board kit dev cyclone iii. My system includes components such as: cpu,jtag,mem, character LCD, PIOs role graphic LCD.
My verilog program as follows:
module bt4 (clkin_50, cpu_resetn, lcd_data, lcd_csn, lcd_d_cn, lcd_e_rdn, lcd_rstn, lcd_wen, lcd_en);
input clkin_50...
I have problems when connect two LCD: Character & Graphics together. Some comon signals don't allow to connect : write enable pin, data/command select pin. How do I correct this error ? I use Cyclone II dev kit
Thanks.
