This is the circuit I have been given for reverse engineering. It has a 4 feet matrix display. It has other features like RS232 input, PS2 Keyboard input, HT1380 RTC, 24C64 EEPROM not shown in circuit. Now the issue is only with matrix display code writing. How should I approach ? The original board uses P89V51RD2 which is obsolete and
Finally I finshed my first project (after 9 months). I wanna show my work to other people and with this Thread i want to share photos, schematics and more.

If this message is moved to a separate thread, please call it: moving up to ARM, chosing between TI Tiva and ST32-F4. I am taking the step up, I have decided, but I have the same problem as you Rezaf. But I have questions from another angle. At the moment I am choosing between TI TIVA (the Launchpad Eval board) and the ST32-F4 (STM F4 Discovery
Hello there ,I like to display a moving message on 3 8*8 dot matrix (ROW Anode) but I am having problem of how to create MAP for characters to display; If you gonna using row scan another use column scan I think you don't use the same characters MAP nor the same circuit;can you please help me to think on this?? see the circuit I want to use,i

The terminal works. I have tested it. thank you Bigdogguru for reply but i don't find the mikroC code that use UART terminal to change the message the only existing code and its hex file its used to display number and we can't change it Post the project files. I will add the UART code to it and also the code to display any Cha
