Detailed Description

The cc2538DK is the new platform by Texas Instruments, based on the cc2530 SoC with an ARM Cortex-M3 core.

Implementation of the low-level SPI primitives such as waiting for the TX FIFO to be ready, inserting into the TX FIFO, etc.

Macro Definition Documentation

#define CC2538_CONF_QUIET 0

Define this as 1 to build a headless node.

The UART will not be initialised its clock will be gated, offering some energy savings. The USB will not be initialised either

Definition at line 152 of file contiki-conf.h.

#define LPM_CONF_MAX_PM 1

Maximum PM.

The SoC will never drop to a Power Mode deeper than the one specified here. 0 for PM0, 1 for PM1 and 2 for PM2

Definition at line 251 of file contiki-conf.h.

Function Documentation

void cc2538_rf_err_isr ( void )

The cc2538 RF Error ISR.

This is the interrupt service routine for all RF errors. We acknowledge every error type and instead of trying to be smart and act differently depending on error condition, we simply reset the transceiver. RX FIFO overflow is an exception, we ignore this error since read() handles it anyway.

However, we don't want to reset within this ISR. If the error occurs while we are reading a frame out of the FIFO, trashing the FIFO in the middle of read(), would result in further errors (RX underflows).

Instead, we set a flag and poll the driver process. The process will reset the transceiver without any undesirable consequences.

Definition at line 730 of file cc2538-rf.c.

References process_poll(), RFCORE_SFR_RFERRF, and RFCORE_SFR_RFERRF_RXOVERF.

void cc2538_rf_rx_tx_isr ( void )

The cc2538 RF RX/TX ISR.

This is the interrupt service routine for all RF interrupts relating to RX and TX. Error conditions are handled by cc2538_rf_err_isr(). Currently, we only acknowledge the FIFOP interrupt source.

Definition at line 701 of file cc2538-rf.c.

References process_poll(), and RFCORE_SFR_RFIRQF0.

void clock_isr ( void )

The clock Interrupt Service Routine.

It polls the etimer process if an etimer has expired. It also updates the software clock tick and seconds counter since reset.

Definition at line 140 of file clock.c.

References CLOCK_SECOND, DISABLE_INTERRUPTS, etimer_next_expiration_time(), etimer_pending(), and etimer_request_poll().

void rtimer_isr ( void )

The rtimer ISR.

Interrupts are only turned on when we have an rtimer task to schedule Once the interrupt fires, the task is called and then interrupts no longer get acknowledged until the next task needs scheduled.

Definition at line 105 of file rtimer-arch.c.

References lpm_exit, NVIC_INT_SM_TIMER, nvic_interrupt_disable(), nvic_interrupt_unpend(), and rtimer_run_next().

void spi_disable ( void )

Disables the SPI peripheral.

Note: Call this function to save power when the SPI is unused.
