16 |
##### How to use this driver ##### |
|
17 |
============================================================================== |
|
18 |
[..] |
|
19 |
(+) Enable the RTC domain access. |
|
20 |
(+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
|
21 |
format using the HAL_RTC_Init() function. |
|
22 |
|
|
23 |
*** RTC Wake-up configuration *** |
|
24 |
================================ |
|
25 |
[..] |
|
26 |
(+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer() |
|
27 |
function. You can also configure the RTC Wakeup timer with interrupt mode |
|
28 |
using the HAL_RTCEx_SetWakeUpTimer_IT() function. |
|
29 |
(+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer() |
|
30 |
function. |
|
31 |
(@) Not available on F030x4/x6/x8 and F070x6 |
|
32 |
|
|
33 |
*** TimeStamp configuration *** |
|
34 |
=============================== |
|
35 |
[..] |
|
36 |
(+) Configure the RTC_AF trigger and enable the RTC TimeStamp using the |
|
37 |
HAL_RTCEx_SetTimeStamp() function. You can also configure the RTC TimeStamp with |
|
38 |
interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function. |
|
39 |
(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() |
|
40 |
function. |
|
41 |
|
|
42 |
*** Tamper configuration *** |
|
43 |
============================ |
|
44 |
[..] |
|
45 |
(+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge |
|
46 |
or Level according to the Tamper filter (if equal to 0 Edge else Level) |
|
47 |
value, sampling frequency, precharge or discharge and Pull-UP using the |
|
48 |
HAL_RTCEx_SetTamper() function. You can configure RTC Tamper in interrupt |
|
49 |
mode using HAL_RTCEx_SetTamper_IT() function. |
|
50 |
|
|
51 |
*** Backup Data Registers configuration *** |
|
52 |
=========================================== |
|
53 |
[..] |
|
54 |
(+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite() |
|
55 |
function. |
|
56 |
(+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead() |
|
57 |
function. |
|
58 |
(@) Not available on F030x6/x8/xC and F070x6/xB (F0xx Value Line devices) |
