Hi,

I'm totally new to this, and I appreciate any helps.

Task: reading battery voltage and system voltage and set watchdog timer to disable.

How:

Reading battery voltage: Read REG0E bit 6-0

Reading system voltage: Read REG0F bit 6-0

Set watchdog timer to disable: Write to REG07 bit 7-0 the value 1000 1101

Question:

How can I send command to accomplish those tasks? You guys can point me to a resource that you use to learn those skills as well if you want.

Thanks.

Tung,

From the field view above, you can simply change the drop down and the value in the drop down is written to the register. To read all registers, you can press the Read Registers button. For individual register reads and writes, you can use the W and R buttons on the right side of the field view.
