  • RE: Need a second UART in an ADuC7021. Is there any soft UART code for this device?

    Is the .c file still available for the software UART on the ADuC7023? I don't see it in this thread.

  • ADUC7021测试看门狗复位后不能用J-LINK 进行调试

    你好! 调试ADUC7021,程序中不使用看门狗,程序正常。当我开启看门狗后,程序里面没有定时喂狗(T3CLRI=1,没有使用写保护),程序按定时的时间复位,此时退出调试模式后,重新上电后用J-LING进入调试模式,程序无法进入 .从此这块电路板再也不能用J-LING进行调试,也就是说,只要我开看门狗,程序出现一次异常看门狗复位一次,我的电路板再也不能进行调试和使用了。请帮我看下怎么解决。多谢了

  • Damaged Code on ADuC7021

    Hello,

    we are using a custom board with ADuC7021. We use page 120  as user space. This page is written every once in a while (say, every day 1 time)

    We had some user complains about losing settings. They probably turned off the device after erasing the…

  • ADUC7023和ADUC7021/22/2x的区别

    请问ADUC7023和ADUC7021/22/2x的区别。

    以前用ADUC7021,现在想换用ADUC7023,看价格似乎便宜些。

    ADUC7019/20/21/22/24/...共一份文档,但ADUC7023却独立一份文档,这个片子有什么特殊吗?

  • RE: ADuC7021上电异常

    我感觉是这两个问题:

    1、你每次下载程序,BM/P0.0是否连接地对以前程序擦除。

    2、晶振是否起振。

  • RE: ADuC7021 Intermittently comes out of reset.

    Try examining the envelope of the external crystal an make sure you are switching from internal to external oscillator at a point where the amplitude of the external oscillator signals are sufficient. Consider the loading effect of the scope probes when…

  • ADUC7021 pll问题

    大家好,aduc7021英文手册里谈到时钟从内部晶振切换到外部晶振时有这样一段话(大概在第51页):

    External Crystal Selection

    To switch to external crystal, clear the OSEL bit in the PLLCON MMR (see Table 32). In noisy environments, noise might couple to the external crystal pins and PLL could lose…
