* \name ADC configuration
|
|
*
|
|
* These values configure which CC2538 pins and ADC channels to use for the ADC
|
|
* inputs. By default the RE-Mote allows two out-of-the-box ADC ports with a
|
|
* phidget-like 3-pin connector (GND/VDD/ADC)
|
|
*
|
|
* The RE-Mote allows both 3.3V and 5V analogue sensors as follow:
|
|
*
|
|
* - ADC1 (PA5): up to 3.3V.
|
|
* - ADC2 (PA4): up to 3.3V
|
|
* - ADC3 (PA2): up to 5V, by means of a 2/3 voltage divider.
|
|
*
|
|
* Also there are other ADC channels shared by default with Micro SD card and
|
|
* user button implementations:
|
|
*
|
|
* - ADC4 (PA6): up to 3.3V.
|
|
* - ADC5 (PA7): up to 3.3V.
|
|
* - ADC6 (PA3): up to 3.3V.
|
|
*
|
|
* ADC inputs can only be on port A.
|
|
* All ADCx are exposed in JP5 connector, but only ADC1 and ADC3 have GND and
|
|
* VDD (3/5V) pins next to it, so these can be exposed into a 3-pin phidget-like
|
|
* connector, for ADC2 either solder a wire to connect, or use a 4-pin connector
|
|
* to expose both ADC1 and ADC2 in a single connector, but this will leave no
|
|
* space for a ADC3 connector.
|
|
*
|
|
* The internal ADC reference is 1190mV, use either a voltage divider as input,
|
|
* or a different voltage reference, like AVDD5, or externally using PA7/AIN7
|
|
* and PA6/AIN6 configurable as differential reference, by removing the R26 and
|
|
* R33 0Ohm resistors to disconnect off the Micro-SD, and those will be
|
|
* accessible from JP5 connector.
|
|
*
|
|
* To enable the ADC[2,4-6], remove any 0Ohm resistors if required (see above),
|
|
* and define in your application `ADC_SENSORS_CONF_ADCx_PIN` and set its
|
|
* value with the corresponding pin number (i.e ADC2 to 4 as mapped to PA4).
|
|
* To disable any ADC[1-6] just define as above, but set to (-1) instead.
|
|
|
|
* Warning: if using ADC6 (PA3), you will need to disable the bootloader by
|
|
* making FLASH_CCA_CONF_BOOTLDR_BACKDOOR equal to zero

|
|
*
|
|
* The shutdown mode is an ultra-low power operation mode that effectively
|
|
* powers-down the entire RE-Mote (CC2538, CC1200, attached sensors, etc) and
|
|
* only keeps running a the on-board RTC and an ultra-low power consumption MCU
|
|
* The Shutdown mode allows:
|
|
*
|
|
* - Put the board in an ultra-low power sleep (shutdown) drawing <150nA avg.
|
|
* - Awake the system by scheduling the RTCC to awake the Low-Power PIC after
|
|
* it disconnects the battery and goes to sleep mode.
|
|
* - Awake the system by using the Low-Power PIC's timer
|
|
*
|
|
* As commented above, S3 can be used to restart the entire board (power
|
|
* management block included), or to kick the board out of shutdown mode by
|
|
* reconnecting the battery.
