I tried to write a program that would flash LED connected tp 8051 Ports ... when i tried to see the output in the hardware (MCBx51 board) by connecting a LED (red) to the corresponding port ... The MCBx51 board already has LEDs on it, and the "Blinky" example to flash them. I suggest you start with that. The board schematics are in the Manual: http://www.keil.com/manuals/mcbx51.pdf You have read the MCBx51 Manual, haven't you...? Keil's MCBx51 page: http://www.keil.com/mcbx51/ |
