ADUC847的DAC 口输出时,要用滤波器吗?

I am a product designer at a company. For a new product we are using ADuC847 Evaluation Board. The board works mostly as a Data Acquisition Device. Unfortunately the newer computers or laptops does not have a Serial Port as required by this particular…

We have been using the ADuC847 for several years. Lately we are getting communication error when trying to reset the controller. The response from the controller indicates its a baud rate error. We tried to replace the crystal or controller and that sometimes…

Hello!

After reset ADUC847 from WDT internal 24-bit sigma-delta ADC changes its own measurement results (about 10%).

When we make the same reset second time, ADC changes its own measurement results to normal (  error 10% disappears)

It depends on how many resets…

Hello all!:

I'm working with an aduc847 and the eval board.

I'm reading the signal from a load cell (from -200uV to 20020uV) and I have a problem with the data readed.

For example, with a little dead load in the cell I have this measurements…

I've been trying to get the debugger to connect to my ADuC847 eval board. I'm not sure how to correctly set the debug program up the right way. I've tried to learn about the program using the help function, but help won't load on my windows…

I have made a PCB with a ADuC847, which is meant to communicate with a ADF7021. The PCB has been design to be a replica of the EVAL-ADF70XXMBZ2 in order to run out-of-tht box with the code from the eval-kit. Somehow, the board is not responding when I…
