    [51] Using 2 main functions in one Keil project

    @FvM: YES, i want to achieve the boot code and APP code in the controller. If BOOT is OK then i need to jump from BOOT CODE to the APPlication code to run interfaced devices and all. In boot code i am not at all using ISR, it just checks for a particular condition.. and Jumps to aPP.

    [51] Using 2 main functions in one Keil project

    YES. i am not using any ISR in APP1, but APP2 uses ISR. i HAVE REDIRECTED the ISR to start address of the APP2. Also, i am linking it using a asm file. Can you please let me know how can i use function pointer to implement the same. Any doc will be helpful. tHanks in advance :) - - - Updated...

    [51] Using 2 main functions in one Keil project

    by two main functions i mean.. In my Keil Project Settings. i have TWO Targets [separate apps, so separate main functions] . the output is separate .hex files. I will burn both the hex files to my 8051.. 0x0000 ~ 0x0FFF == APP1.hex 0x1000 ~ 0x1FFFF == APP2.hex

    [51] Using 2 main functions in one Keil project

    Hello All, I am making 2 applications [ separate apps having separate main functions ] on 8051 controller . So, i need to jump from APP1 to APP2 depending upon the execution. I am using the KEIL V7.10 Compiler. I am having trouble jumping from one app to other. It jumps from one app, but do...

    USB Controller with Modulator as a transiever

    Hi all, I am starting a project. The block diagram looks like this: PC-->USB Port--->MCU-->Modulator(any modulation can work)-->Amplifier-->Transmit Receive-->Pre-Amp-->Demod--> Output to PC The first half is transmitter.. second half is receiver... i am starting to think what kind of...

    RF and Zigbee Co-existence

    one thing that is pure necessary is EMI Interference. need to take care of that. Rest all will be fine.. EMI filters matters. not the distance..

    Enumeration in C language

    hi, the enum can not be used as a type.. here in struct, you are using enum wrongly. just declare a variable (integer). then check that against the enum value.

    delete data from eeprom

    EEPROM Clearing is nothing but just all 1's in the memory. So just put 0xFF and write it to entire memory.

    Problem with reading data from eeprom 24c32

    one thing, you have left WP Pin floating.. may be that is the reason.. Check and reply. im looking into code.

    Problem with reading data from eeprom 24c32

    The best solution to giving delay is using the counter of MCU.. rather than stopping the microcontroller for giving delay in a loop, just make it interrupt based.
