169 * \name ADC configuration
170 *
171 * These values configure which CC2538 pins and ADC channels to use for the ADC
172 * inputs. By default the RE-Mote allows two out-of-the-box ADC ports with a
173 * phidget-like 3-pin connector (GND/VDD/ADC)
174 *
175 * The RE-Mote allows both 3.3V and 5V analogue sensors as follow:
176 *
177 * - ADC1 (PA5): up to 3.3V.
178 * - ADC2 (PA4): up to 3.3V
179 * - ADC3 (PA2): up to 5V, by means of a 2/3 voltage divider.
180 *
181 * Also there are other ADC channels shared by default with Micro SD card and
182 * user button implementations:
183 *
184 * - ADC4 (PA6): up to 3.3V.
185 * - ADC5 (PA7): up to 3.3V.
186 * - ADC6 (PA3): up to 3.3V.
187 *
188 * ADC inputs can only be on port A.
189 * All ADCx are exposed in JP5 connector, but only ADC1 and ADC3 have GND and
190 * VDD (3/5V) pins next to it, so these can be exposed into a 3-pin phidget-like
191 * connector, for ADC2 either solder a wire to connect, or use a 4-pin connector
192 * to expose both ADC1 and ADC2 in a single connector, but this will leave no
193 * space for a ADC3 connector.
194 *
195 * The internal ADC reference is 1190mV, use either a voltage divider as input,
196 * or a different voltage reference, like AVDD5, or externally using PA7/AIN7
197 * and PA6/AIN6 configurable as differential reference, by removing the R26 and
198 * R33 0Ohm resistors to disconnect off the Micro-SD, and those will be
199 * accessible from JP5 connector.
200 *
201 * To enable the ADC[2,4-6], remove any 0Ohm resistors if required (see above),
202 * and define in your application `ADC_SENSORS_CONF_ADCx_PIN` and set its
203 * value with the corresponding pin number (i.e ADC2 to 4 as mapped to PA4).
204 * To disable any ADC[1-6] just define as above, but set to (-1) instead.
205
206 * Warning: if using ADC6 (PA3), you will need to disable the bootloader by
207 * making FLASH_CCA_CONF_BOOTLDR_BACKDOOR equal to zero

486 * The RE-Mote features an on-board external WDT and battery monitor, which
487 * adds more robustness and prevents the mote to run wild if any unexpected
488 * problem shows-up.
489 * The external WDT requires a short pulse (<1ms) to be sent before a 2-second
490 * period. The battery monitor keeps the device in Reset if the voltage input
491 * is lower than 2.5V.
492 * The external WDT can be disabled by removing the R34 0Ohm resistor.
493 * As default the Texas Instrument's TPS3823 WDT is not mounted.
494 * Alternatively the testpoint or unused WDT's pad can be used to re-use as GPIO
