IS (Force Sample)

Forces a read of all enabled digital and analog input lines. The data is returned through the UART or
SPI.
When operating in Transparent mode (AP = 0), the data is returned in the following format:
All bytes are converted to ASCII:
number of samples<CR>
channel mask<CR>
DIO data<CR> (If DIO lines are enabled)
ADC channel Data<CR> (This will repeat for every enabled ADC channel)
<CR> (end of data noted by extra <CR>)
When operating in API mode (AP = 1), the command immediately returns an OK response. The data
follows in the normal API format for DIO data.
Parameter range
N/A
Default
N/A

IO (Digital Output Level)

Sets digital output levels. This allows DIO lines setup as outputs to be changed through Command
mode.
Parameter range
8-bit bit map; each bit represents the level of an I/O line set up as an output
Default
N/A

IC (DIO Change Detect)

Set or read the digital I/O pins to monitor for changes in the I/O state.
Each bit enables monitoring of DIO0 - DIO7 for changes. If detected, data is transmitted with DIO data
only. Any samples queued waiting for transmission is sent first.
Set unused bits to 0.
Parameter range
0 - 0xFFFF (bit field)
Default
0
