![]() ![]() the fourth hex digit of the 16-bit number end case Įnd process Now, let's use it for displaying a counting hexadecimal number on the 4-digit seven-segment display on Basys 3 FPGA. LED_BCD <= displayed_number( 3 downto 0) activate LED4 and Deactivate LED2, LED3, LED1 My question is given this configuration, I don't understand how to drive each digit separately. I was looking at the datasheet for the LTC-4627JR, and it looks like each digit shares a common anode, and each segment shares a common cathode. 7-segment display controller - generate refresh period of 10.5ms process(clock_100Mhz,reset) 7-segment LED display with multiple digits. A digital stopwatch built around timer IC LM555 and 4-digit counter IC MM74C926 with a multiplexed 7-segment LED display. ![]()
