CSLIB library hardware configuration
Description
Hardware configuration for CSLIB.
These definitions configure the capacitive sensing hardware in active and sleep mode scans. They also configure channel-by-channel thresholds and expected touchd deltas.
Macros |
|
#define | DEF_NUM_SENSORS 2 |
Defines the size of the sensor node array.
|
|
#define | MUX_VALUE_ARRAY 0, 1 |
Cross reference between sensor number ordering and pin ordering.
|
|
#define | ACTIVE_THRESHOLD_ARRAY 70, 70 |
Per channel active threshold setting.
|
|
#define | INACTIVE_THRESHOLD_ARRAY 30, 30 |
Per channel inactive threshold setting.
|
|
#define | AVERAGE_TOUCH_DELTA_ARRAY 64 >> 4, 64 >> 4 |
Per-channel expected touch delta.
|
|
#define | CSLIB_MUX_INPUT 3, 4 |
Per channel ACMP_CAPSENSE channel value for each enabled sensor.
|
|
Variables |
|
const uint16_t | CSLIB_muxInput [] |
Array stores ACMP input settings.
|
|
const uint8_t | CSLIB_muxValues [] |
Array of cross-references between sensor number and actual pin number.
|

Macro Definition Documentation
◆ DEF_NUM_SENSORS
#define DEF_NUM_SENSORS 2 |
Defines the size of the sensor node array.
Also defines volatile arrays that have a one-to-one correspondence to the number of sensors in the project.
- Note
- Minimum value is 1, maximum value is the number of capacitive sensing-enabled pins on the device
◆ MUX_VALUE_ARRAY
#define MUX_VALUE_ARRAY 0, 1 |
Cross reference between sensor number ordering and pin ordering.
This allows for using pins that are not in order when doing layout.
◆ ACTIVE_THRESHOLD_ARRAY
#define ACTIVE_THRESHOLD_ARRAY 70, 70 |
Per channel active threshold setting.
- Note
- Minimum threshold used is INACTIVE_THRESHOLD_ARRAY value, maximum value is 100
◆ INACTIVE_THRESHOLD_ARRAY
#define INACTIVE_THRESHOLD_ARRAY 30, 30 |
Per channel inactive threshold setting.
- Note
- Minimum threshold used is 1, maximum value is ACTIVE_THRESHOLD_ARRAY
◆ AVERAGE_TOUCH_DELTA_ARRAY
#define AVERAGE_TOUCH_DELTA_ARRAY 64 >> 4, 64 >> 4 |
Per-channel expected touch delta.
This value describes the difference in capacitive sensing output codes between the inactive/baseline of the sensor, and the output of the sensor when active(touched).
- Note
- These values should be defined in terms of X/16, or X>>4, as they are stored in a packed byte array
◆ CSLIB_MUX_INPUT
#define CSLIB_MUX_INPUT 3, 4 |
Per channel ACMP_CAPSENSE channel value for each enabled sensor.
Variable Documentation
◆ CSLIB_muxInput
const uint16_t CSLIB_muxInput[] |
Array stores ACMP input settings.
Array stores ACMP input settings.
◆ CSLIB_muxValues
const uint8_t CSLIB_muxValues[] |
Array of cross-references between sensor number and actual pin number.
Array of cross-references between sensor number and actual pin number.
Array of cross-references between sensor number and actual pin number.
Array of cross-references between sensor number and APORT number.
◆ sendComms
uint8_t sendComms |
Only send comms after new values.
