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 is my code(in keil c) i guess i have ...
what are the advantages of using atmega32 than other microcontrollers ? is it better than pic and arm,8051 ? ...
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, so I'd rather not do PIC now; otherwise,...
I'm writing a program for a 8051 microcontroller. In the first part of the program I do some calculations and based on the result, I either light the LED or not (using CLR P1.7, where P1.7 is the port the LED is attached to in the microcontroller). In the next part of the program I want to retrieve the bit, perhaps store it somewhere, a...
Hello, According to this: http://www.8052.com/tutsfr.php , the sfrs whose address are divisible by 8 are bit addressable. You can do things like SETB or CLR on them. But aren't they overlap other memory addresses? I mean, for example, P0 is in 80h. So P0.0 will be 80h, P0.1 will be 81h. But 81h is the address of SP. Aren't they overlap?...
I'm using uCsim to do unit test on SDCC projects. In uCsim/S51, you can simulate serial line traffic by s51 -s /dev/tty PROGRAM.ihx or s51 -S in=testdata.in,out=testdata.out PROGRAM.ihx In the latter form, the data is immediately sent to the simulator which causes a lot of frames are lost. So instead of given the test data in p...
I'm writing to memory space a few address and I need to optimize the code. There is a better way to do the following? SETB 00h SETB 01h SETB 02h SETB 03h SETB 04h SETB 05h SETB 06h SETB 07h ...
i am supposed to code a bubble sort program in embedded C using keil uVision. I havnt yt understood what is it that is actually required. I have been told to use registers and/or ports in it. if anyone can understand what exactly has to be done pls help me out... ...
