Adresse im CG RAM setzen Daten des Zeichens 1.) The commandCG RAM Address Se set the Bit Adresse Hex Hex pointer (bit 3,4,5) to the 1st dot line of the new 7 6 5 4 3 2 1 0 character. The individual dot line will be 000 40 0 0 1 0 0 04 addressed by bits 0,1 and 2. With this example a 001 41 0 0 1 0 0 04 character with ASCII code 00 will be defined. 010 42 0 0 1 0 0 04 2.) The commandData Writ defines the upper 011 43 0 0 1 0 0 04 01 000 XXX dot row (here: 0x40). The next Data Write 100 44 1 0 1 0 1 15 commands are for the other dot rows. Full 101 45 0 1 1 1 0 0E definition requires 8 write cycles where the last 110 46 0 0 1 0 0 04 one is the cusor line. 111 47 0 0 0 0 0 00 3.) This new defined character will be used like a normal ASCII character 0x00 DD RAM Address Se,Data Writ). Page 2 Printing and typographical errors reserved.
