/* There is 8K of rtc_slow_memory, but some is used by the system software
|
2019-08-12 02:21:47 +01:00
|
|
|
If the MICROPY_HW_RTC_USER_MEM_MAX is set too high, the following compile error will happen:
|
2018-02-15 15:35:37 +00:00
|
|
|
region `rtc_slow_seg' overflowed by N bytes
|
|
|
|
The current system software allows almost 4096 to be used.
|
|
|
|
To avoid running into issues if the system software uses more, 2048 was picked as a max length
|
2019-08-12 02:21:47 +01:00
|
|
|
|
|
|
|
You can also change this max length at compile time by defining MICROPY_HW_RTC_USER_MEM_MAX
|
|
|
|
either on your make line, or in your board config.
|
|
|
|
|
|
|
|
If MICROPY_HW_RTC_USER_MEM_MAX is set to 0, the RTC.memory() functionality will be not
|
|
|
|
be compiled which frees some extra flash and RTC memory.
