• RE: ADUC7021 :general purpose register address.

    I have proper SW running for I2C. I am able to access registers from ADUC7021 through FPGA via I2C. My confusion is that where I can get the register details of ADUC7021 like 0x0 register is version register, 0x1 is die temperature register.

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

    The appended .c file is for the ADuC7023.

    However, you should only need to change the header file called to ADuC7021.h

  • RE: SPI slave chip select problem

    If you do not use the /CS signal you have no control about start and stop of a frame.

    You may use a GPIO from the ADuC7021 itself to toggle the /CS, but still there is a potential problem if you have noise on the SPICLK. This can cause a extra bit shift…

  • ADuC702x: Tying off unused GPIO pins

    We are using the ADUC7021 in a reference design.  We are not planning on using pins 18 and 21.  Do you see any issues tying these pins directly to VDD?
