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.
The appended .c file is for the ADuC7023.
However, you should only need to change the header file called to ADuC7021.h
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…
Thanks 4 ur replys………..JJJ

Could you please help provid the ucos II/III code run on ADuC7021?
Thanks a lot for your help!
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?
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…
I use pin 3 of port 1 (P1.3) on my products and at power up, the port is in high impedance, everything is ok.
Now we received a new reel of aduc7021 and this port (pin 1.3) now emit a glitch at power_up : 2V during 17ms with a pull down of 68Kohm…
