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: 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).

RE-Mote Button configuration

Buttons on the RE-Mote are connected as follows:

  • BUTTON_USER -> PA3, S1 user button, shared with bootloader and RTC_INT1
  • BUTTON_RESET -> RESET_N line, S2 reset both CC2538 and CoP
  • BUTTON_PIC1W -> shared with SHUTDOWN_ENABLE, not mounted.
#define BUTTON_USER_PORT   GPIO_A_NUM
 BUTTON_USER -> PA3.
 

Detailed Description

The RE-Mote was designed jointly with universities and industry partners in RERUM European project, to ease the development of private and secure applications for IoT and Smart City applications. The RE-Mote packs several on-board resources, like a RTC, external WDT, Micro-SD, RF switch and a Shutdown mode to reduce its power consumption down to 300nA.
