This should be considered a traditional device, just a timer (1-64s), so you don't have to be surprised. The power consumption is 30nA, which I think I can't test. Below are the basic parameters. The ...
Only the writing function of TWI is tested, and the device address, register address and data are written respectively. However, only the device address and data are seen from the oscilloscope, and th...
I right-clicked on the column name, selected columns, and added description and library myself. It worked at the time, but why did I close the software and reopen it, and the "description and library"...
