I'm a first year Computer Science student looking to get started with development for micro-controllers. I'd like to use the 8051, as it's common as dirt, and is used frequently in the real world.
During my junior or senior year, I'll be taking a PIC micro-controller based embedded design class…

Hi, in school I have written many programs for 8051 compatible CPU. But I never actually knew how our "debug" sets worked. I mean, we test our programs in special sets, which actually allow you to very simply load program to CPU via PC serial port. But I thing you know this musch more better than…

The connection is as follows An infrared sensor circuit which yields 0 or 5v depending on closed or open circuit output line to port 2_0 pin of microcontroller 8051 philips.Problem is when i do this the circuit value are overridden by the current value on port 2_0 led always goes on.Here…

I'm thinking about using a microcontroller with an 8051 core from Silicon Laboratories.
I hope that I can use C rather than assembly language, so I installed SDCC.
I installed the "Silicon Laboratories IDE" to download the executable binaries to the on-chip Flash program memory.
It also supposedly…
