Firefly LED configuration | |
LEDs on the Firefly are connected as follows:
LED1 pin exposed in JP2 connector LED2 pin exposed in JP2 connector LED3 pin exposed in JP2 connector | |
UART configuration | |
On the Firefly, the UARTs are connected to the following ports/pins:
We configure the port to use UART0 and UART1, CTS/RTS only for UART1, both without a HW pull-up resistor. UART0 is not exposed anywhere, UART1 pins are exposed over the JP3 connector. | |
#define | UART1_CTS_PORT (-1) |
GPIO_D_NUM. | |
#define | UART1_CTS_PIN (-1) |
1 | |
#define | UART1_RTS_PORT (-1) |
GPIO_D_NUM. | |
#define | UART1_RTS_PIN (-1) |
0 | |
ADC configuration | |
These values configure which CC2538 pins and ADC channels to use for the ADC inputs. There pins are suggested as they can be changed, but note that only pins from PA can be configured as ADC.
Only ADC1 and ADC3 are enabled as default. The internal ADC reference is 1190mV, use either a voltage divider as input, or a different voltage reference, like AVDD5 or other externally (AIN7 or AIN6). | |
#define | ADC_SENSORS_PORT GPIO_A_NUM |
ADC GPIO control port. | |
#define | ADC_SENSORS_ADC1_PIN 5 |
ADC1 to PA5 | |
#define | ADC_SENSORS_ADC2_PIN 4 |
ADC2 to PA4 | |
#define | ADC_SENSORS_ADC3_PIN 2 |
ADC3 to PA2 | |
#define | ADC_SENSORS_ADC4_PIN 6 |
ADC4 to PA6 | |
#define | ADC_SENSORS_ADC5_PIN 7 |
ADC5 to PA7 | |
#define | ADC_SENSORS_ADC6_PIN (-1) |
ADC6 not declared | |
#define | ADC_SENSORS_MAX 5 |
Maximum sensors | |
Firefly Button configuration | |
Buttons on the Firefly are connected as follows:
| |
#define | BUTTON_USER_PORT GPIO_A_NUM |
BUTTON_USER -> PA3. | |
SPI (SSI0) configuration | |
These values configure which CC2538 pins to use for the SPI (SSI0) lines, reserved exclusively for the CC1200 RF transceiver. These pins are exposed to the JP3 connector. To disable the CC1200 and use these pins, just remove the R10 resistor (0 ohm), which powers both the CC2538 and CC1200 to only power the SoC. TX -> MOSI, RX -> MISO | |
SPI (SSI1) configuration | |
These values configure which CC2538 pins to use for the SPI (SSI1) lines, exposed over JP3 connector. TX -> MOSI, RX -> MISO | |
I2C configuration | |
These values configure which CC2538 pins to use for the I2C lines, exposed over JP3 connector. | |
Dual RF interface support | |
Enables support for dual band operation (both CC1200 and 2.4GHz enabled). Unlike the RE-Mote, the Firefly doesn't have a RF switch, so both interfaces should be always enabled if the R10 resistor is mounted. If only using the 2.4GHz RF interface, the resistor can be removed to power-off the CC1200. | |
CC1200 configuration | |
These values configure the required pins to drive the CC1200 None of the following pins are exposed to any connector, kept for internal use only | |
