Seven Segment Multiplexing using PIC18F4550 Microcontroller— URGENT HELP NEEDED PLEASE!

[Yuvanampi Thaiveegan]

i used the codes exactly as given in the website. but the output of RD4,RD5 and RD6 (which are 7segment display legs ‘e’, ‘f’, and ‘g’) do not function. is there something wrong with the programming? i have checked the hardware connections multiple times and nothing seems to be wrong.

STEP 1: Make a look up table having values for the displaying each digit.

STEP 2: Select the SSD in which you want to display the values.

STEP 3: Read the value from look up table.

STEP 4: Send it to the port where the data lines of SSD is connected.
