hi sir, this is my first project to build attiny moving text with serial interface.
source from here **broken link removed**
I think all of the manufacture of hardware is correct and has filled the hex file into attiny also true. but his results do not display the alphabetic characters. what I'm ordering from delphi program the hardware does not function at all. with or without a command from the serial port, it displays the same results only 7x5 dot light box, lit from right to left without any form of characters written.
about which there is a problem? I suspect he made a delphi program from your computer to interface dotmatrix device is not working. because when the program starts to give commands to the device dot matix, tx & rx indicator light on my computer does not flash at all, unlike other programs that use a serial interface that is always the indicator blinks when the program is run. thanks for ur attention
look like this
