I implemented USTICKER feature.
The mainly changing is here.
- I added a macro to mbed_drv_cfg.h for commonalizing code for GR-PEACH and GR-LYCHEE with different clock frequencies, and referenced it's macro at us_ticker.c.
- ticker_init()
Currently, ticker_init() keep counting, disables the ticker interrupt, and is safe to call repeatedly.
Therefore, in order to satisfy specifications, I removed GIC_EnableIRQ at end of function and added GIC_DisableIRQ at begin of function.
When an interrupt is required, it will be set with ticker_set_interrupt().
If executing the following, the counter has been initialized. So it will not call after executing the first time.
OSTM1TT = 0x01; /* Stop the counter and clears the OSTM1TE bit. */
OSTM1TS = 0x1; /* Start the counter and sets the OSTM0TE bit. */
- ticker_free()
this function stops the counting and powerdown the us_ticker.
To satisfy the mbed specificationm, I implemented free() function.
- ticker_read()
Currently, Mbed spec's frequeny is between 250KHz and 8MHz, but the frequency that is used at my ticker is 33MHz.
Therefore, in order to satisfy specifications, I changed the process to return the timer counter value divided by 32(33MHz / 32).
Since the calcurate function by using 64 bit is no longer necessay, I removed it.
- ticker_set_interrupt()
Same as the above read(),
In order to satisfy specifications, I changed the process to set the value multiplied by 32.
- ticker_fire_interrupt()
In order to satisfy specifications, I implemented fire_interrupt() function.
Also I added GIC_EnableIRQ for allowing the interrupt at end of function.
- ticker_get_info()
To satisfy the mbed specificationm, I implemented ticker_get_info() function. The value of freq includes rounding off.
I made be available in common whatever the board related to RZ_A1 in the below files.
- Since there are the table code of Pinmap differs for each board, I moved the code to "PeripheralPins" file for each board, and changed to include PeripheralPins.h.
analogin_api.c, can_api.c, gpio_irq_api.c, i2c_api.c, pinmap.c, port_api.c, pwmout_api.c, serial_api.c, spi_api.c and us_ticker.c
- Since there are some board-specific processes, I enclosed the processes with "#ifdef" and rearranged the functions to make be easier to enclose.
can_api.c, ethernet_api.c and serial_api.c
- Since there are the driver configuration values differs for each board, I added "mbed_drv_cfg.h" file for each board and defined macros for the values, and changed to refer to the macros.
can_api.c, gpio_api.c, pwmout_api.c and rtc_api.c
