EFN English Font display Network module INTRODUCTION EFN English Font display Network is a display module displaying English character on 5x7 of Dot matrix LED through simple serial communication It can display all English character and 0 9 of digits and that special character such as etc When EFN receives ASCII code through RS232 it will display related character GENERAL DESCRIPTION RS232 serial communication 5V level 9600 baud rate Protocol is fixed as N 8 1 Connect up to 127 of EFN on one RS232C line by adjusting addresses Display English Capital lower case digit as per ASCII code HOW TO USE gt TRANSMISSION FORMAT If you send 3 bytes of data in the form shown below to EFN EFN displays English character related to ASCII code 255 0 127 32 127 Start code Address ASCII code 255 is Start code 0 127 is Address code indicating which EFN data will be sent to 32 127 is ASCII code EFN will display English character related to the ASCII code gt USAGE IN PICBASIC You can operate EFN much simpler by SEROUT instruction of PICBASIC language The following is an example of SEROUT instruction with PB 1S 2S SEROUT 0 30 0 0 255 0 amp H41 piceae O F F core nooo annnnnnannnnnnn 24LC32 PIC16C73 04 SP OOOO CO 2 OVRESGNIO 1 2 3 4 5 7 8 10 1 12 13 14 15 CLK PB 4123 4 5 6 7 8 9 10
