Pager Service
Hello, I'm currently working on a research about pagers or beepers. Does anyone have any good site that can help me with the communication techniques regarding pagers? Like multiplexing, signal formats etc.
Hello... anyone know of any programmer for PIC microcontrollers using the parallel port??? If you do, can I have a schematic or board layout and what software is used to upload the hex file to the microcontroller. Thanks!!!
Hassan,
Can I know your design? I actually did it with pic16f85 and 4017 but it only worked for 1 5x7 and I need to scroll the text in 7 pcs of 5x7. Can you help?
I've been through that but I actually can't understand coz most are for atmel and the sites posted there have no hardware schematics so I can't understand. If someone can explain it I'll be very thankful!
I'm sorry. I have 7 displays. The character is scrolling. I don't know what lcd controller is.
Added after 1 minutes:
I want to have as many characters as possible scrolling.
