• ADuC7124 can not be supported well on Keil or IAR with emulator

    1. The recent part ADuC7124 did not supported very well currently, with keil provided within the ADuC7124 CD, it is recognized as ADuC7023 and thus specific features/registers can not be accessed via emulator.

    2. IAR did no support ADuC7124 yet.


  • On the ADuC7124 I can't protect flash block 1 using the ARMWSD serial downloader

    On the ADuC7124 I can't protect flash block 1 (the one with lower addresses ) using the ARMWSD serial downloader.

    I downloaded a piece code to the ADuC7124 using ARMWSD and write protected it.

    After a reset I was able to overwrite it.

  • Possible Bug on ADuC7124?


    the last 2 days is had trouble with the interrupt on T1 (GP Timer). I found that the interrupt could not be cleared, even though T1CLRI was set to clear the interrupt and T1CON was set to 0x200 (disabled, with 32kHz Clk). So, the interrupt occured…

    Hi Patrick,

                  Thanks for your reply.  I reverted to 4.42c (I couldn't find v4.40f) and I am able to download and debug now.

    Please let me know when the issues is resolved with the latest drivers.


  • ADuC7023: What are the rising and falling trigger levels for edge based interrupts?

    On the ADuC7023, at what voltage on the input pin  will a)  a rising edge  external interrupt be triggered b) a falling edge external interrupt?

    The same question applies for the ADuC7121, ADuC7122, ADuC7124 and ADuC7126.

  • RE: If using an ADI micorcontroller in a LFCSP package, how do I connect the exposed paddle on the underside of the package on my PCB?

    On the following parts, the exposed paddle is used for mechanical stability and should be connected to a large pad on your PCB but, this pad should not be connected to ground or any other track:

    ADuC7019, ADuC7020, ADuC7021, ADuC7022, ADuC7023, ADuC7024…
