I added a port-specific module, RTC to ports/analog. Now the analog port is capable of
handling `rtc.set_time_source()`, `rtc.RTC()` and `r.datetime()`. Note that the RTC
calibration functions are not implemented and is planned for near future.
The implementation in the RTC module also enables two functions in the time module,
which are `time.time()` and `time.localtime()`.
The following example prints the current time every second:
import time
import rtc
r = rtc.RTC)
r.datetime = time.struct_Time((2000, 1, 1, 1, 1, 1, 0, -1, -1))
while(True):
current_time = r.datetime
print(current_time)
time.sleep(1)

Summary
I added a port-specific module, RTC to ports/analog. Now the analog port can handle
rtc.set_time_source(),rtc.RTC()andr.datetime(). Note that the RTC calibration functions (common_hal_rtc_get_calibration()andcommon_hal_rtc_set_calibration()) are not implemented and are planned for the near future.The implementation in the RTC module also enables two functions in the time module, which are
time.time()andtime.localtime().The following example prints the current time once per second:
The expected output is:
The following example call functions from the time module that rely on the RTC module. Successful execution confirms that the newly integrated RTC module enables these related functions in the time module.
An example of the expected output is:
Testing
After I finished implementing the module, I built and flashed the project in the
ports/analogdirectory using OpenOCD with a J-Link device. After flashingfirmware.elfto an AD-APARD32690-SL, I ran the code snippets in both code.py and REPL and received expected results.
