Description:
|
|
SX9324 has 3 inputs, CS0, CS1 and CS2. Hardware layout
|
|
defines if the input is
|
|
|
|
+ not connected (HZ),
|
|
+ grounded (GD),
|
|
+ connected to an antenna where it can act as a base
|
|
(DS - data shield), or measured input (MI).
|
|
|
|
The sensor rotates measurement across 4 phases
|
|
(PH0, PH1, PH2, PH3), where the inputs are configured
|
|
and then measured.
|
|
|
|
By default, during the first phase, [PH0], CS0 is measured,
|
|
while CS1 and CS2 are used as shields.
|
|
`cat in_proximity0_setup` returns "MI,DS,DS".
|
|
[PH1], CS1 is measured, CS0 and CS2 are shield:
|
|
`cat in_proximity1_setup` returns "DS,MI,DS".
|
|
[PH2], CS2 is measured, CS0 and CS1 are shield:
|
|
`cat in_proximity1_setup` returns "DS,DS,MI".
|
|
[PH3], CS1 and CS2 are measured (combo mode):
|
|
`cat in_proximity1_setup` returns "DS,MI,MI".
|
|
|
|
Note, these are the chip default. Hardware layout will most
|
|
likely dictate different output. The entry is read-only.
