Hi All,
I need guidance to select the right PIC preferable PIC16F or PIC18F type for the purpose of LED multiplexing display.
The scrolling message consists of 51 characters including spacing, the LED dot matrix is 7 rows by 15 columns, the rows are controlled by MCUs port, and columns are controlled by two units of 74HC138, a 3 to 8 line de multiplexer, via MCUs port. Its datasheet is attached.
I tried 16F628A, it could handle scrolling message of around 20 characters, but for 51 characters encountered out of memory when trying to compile. Could the experts here give advice for the correct PIC I should be using? In the PIC datasheet which figure should I be notice? The SRAM or EEPROM?
Thanks
