|
|
* phidget-like 3-pin connector (GND/VDD/ADC)
|
|
*
|
|
* The RE-Mote allows both 3.3V and 5V analogue sensors as follow:
|
|
*
|
|
* - ADC1: up to 3.3V.
|
|
* - ADC2: up to 3.3V, shared with RTC_INT
|
|
* - ADC3: 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: up to 3.3V.
|
|
* - ADC5: up to 3.3V.
|
|
* - ADC6: 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 other externally (AIN7), but
|
|
* note the PA7 is shared with the Micro-SD CSn pin, likewise for PA6 (AIN6)
|
|
* shared witht the Micro-SD select pin
|
|
* To use the ADC2 pin, remove the resistor on the Zoul's PA4 pin (JP1, pin 10)
|
|
* and enable below (replace -1 with 4).

* an ultra-low power consumption MCU (PIC12F635). The Shutdown mode allows:
|
|
*
|
|
* - Put the RE-Mote in an ultra-low power sleep (shutdown) drawing <200nA avg.
|
|
* - Periodically awake and execute tasks, being the shutdown period selectable
|
|
* via R47 resistor value (22KOhm as default for 1 minute shutdown period).
|
|
* - Enter shutdown mode before the shutdown period expiration, by invoking the
|
|
* PM_SHUTDOWN_NOW macrp
|
|
*
|
|
* The shutdown mode can be disabled by hardware by short-circuiting or placing
|
|
* an 0Ohm resistor across W1 pad.

|
|
