DSPS use GPIO control into its extended sleep and wake up.

Hi Lane,

In order for you to check how to enable the external wakeup mechanism and how to register a callback function please have a look at the smart tag reference design in the app_button_press_cb() function. Also please have a look at the document UM-B-051 at section 10.7 Wakeup Timer.

Thanks MT_dialog

Hi Lane,

Please follow the example in the Smart Tag reference design in order to wake up, check the app_button_press_cb() function (wakes up the da from a button). You can check if the configuration is ok by using a button to wake it up and then implement the CTS wake up.

Thanks MT_dialog

Thanks Lane and MT_dialog,

I just met the same problem. Lane should be right. Following function in the SDK 5.0.3 (and also SDK 3.x.x) seems to have a problem...


void ext_wakeup_enable(uint32_t port, uint32_t pin, uint8_t polarity)
{
rwip_env.ext_wakeup_enable = 2;
#if DEVELOPMENT_DEBUG
RESERVE_GPIO( EXT_WAKEUP_GPIO, (GPIO_PORT) port, (GPIO_PIN) pin, PID_GPIO );
#endif
if ( polarity == 0 ) // active low
GPIO_ConfigurePin((GPIO_PORT) port, (GPIO_PIN) pin, INPUT_PULLUP, PID_GPIO, false ); // active low. Set default to input high.
else//高电平
GPIO_ConfigurePin ((GPIO_PORT)端口(GPIO_PIN)πn, INPUT_PULLDOWN, PID_GPIO, false ); // active high. Set default to input low.

wkupct_register_callback(ext_wakeup_cb);

wkupct_enable_irq（1<}

If we call this function like:
ext_wakeup_enable( GPIO_PORT_2, GPIO_PIN_3, 0)
this method callswkupct_enable_irq()function withwrong parametersin the end.
wkupct \u enable \u irq（）函数需要以下参数：

/**

If there are good solution to solve this, please let me know.

提前感谢您的支持。

Hi CD,

ext\u wakeup\u enable是一个只应用于完全嵌入式设计的函数，此实现不是您尝试使用它的原因。要使用唤醒控制器，请使用唤醒驱动程序的API实现。您可以在参考设计中找到与ext\u wakeup\u enable的实现类似的示例。

Thanks MT_dialog

Hi MT_dialog,

Thanks for your quick reply.

Sorry, I'm getting confused... Please let me confirm the things there....

1我的环境：我想使用DA14583作为全嵌入式设计。
2. Your comment is:

The ext_wakeup_enable is a function that should be used only with full embedded designs, this implementation isn't for the reason you are trying to use it.

Can I use ext_wakeup_enable() function for the full embedded design system? Or do you want to mean ext_wakeup_enable() function should be used with "external processor running host application"?
在源代码中，有一些关于这些东西的注释，但是我真的很困惑。。。

As I listed up above, there are same #if statements "#if ((EXTERNAL_WAKEUP) && (!BLE_APP_PRESENT))", but the comments for those are mixed with full embedded and external processor per a file or a function.
If I used DA1458x as a full embedded design, I should code as followings, is it right??? :

#undefCFG_EXTERNAL_WAKEUP

而且在完全嵌入式设计系统时，不会调用arch\u goto\u sleep（）函数中的ext\u wakeup\u enable（），不是吗？！我的理解对吗？！？
So, as you mentioned, we have to use wake up controller to wake up on full embedded design system. I believe the code for waking up would be something like followings:
1st: Register callback function when system wakes up: using wkupct_register_callback()
第二：为唤醒启用IRQ:wkupct_Enable_IRQ（0x40000，0x40000，1，0）；//i、 e.P2琰2，P2琰2的低电平有效，1个事件，去抖动时间=0毫秒
当我在上面编码时，我的系统似乎醒了过来让我检查一下对话框中关于GPIO唤醒的一些示例项目。）

3. Even though ext_wakeup_enable() is desinged for only full embedded (or external processor host?) design, ext_wakeup_enable() function in arch_system.c seems wrong, as Lane mentioned too, I think.
ext_wakeup_enable() function needs 3 parameters, wakeup GPIO port, pin and polarity. So, if users want to wake up P2_2 with low active event, user call this like: ext_wakeup_enable(GPIO_PORT_2, GPIO_PIN_2, 0).
On the other hand, in ext_wakeup_enable() function, port information(i.e. GPIO_PORT_2) is completely lost. wkupct_enable_irq() function required bit expression to select port and pin including port information. Current code of ext_wakeup_enable() can a handle the signal change on only PORT_0. (In other words, ext_wakeup_enable(GPIO_PORT_2, GPIO_PIN_2, 0) will be modified to GPIO_PORT_0, GPIO_PIN_2 with low active event in ext_wakeup_enable() function.

Sorry for my long reply, but if you could provide any comments on this, it would be much appreciated.

Thanks for your great support.

Hi CD,

Just some clarifications fully mbeded -> Application runs on external MCU, fully hosted -> application runs on DA

I haven't realised that you were using a fully embedded design (running from an external host), since you are, then yes you can use the function. The thing is that the code assumes that you are going to use only pins from port 0. This part must be corrected, and will be in future SDK versions. If you are going to use a fully embedded design and you run your application from an external host and you want your device to wake up from an external MCU then you have to configure the external wake up. The ext_wakeup_enable() is used in full embedded designs (since the application should wake up from the external proccessor). If your design was fully hosted then you should use the code you are mentioning.

Thanks MT_dialog

Hi MT,

Thank you very much for your comments.
Yes, you are right. I had mixed up "full embedded" with "fully hosted". I'm so sorry about this...

As you mentioned, we would like to use DA1458x as "fully hosted" design (using DA as an integrated processor).

So I have to code like followings, is it right?

#undefCFG_EXTERNAL_WAKEUP
系统唤醒时注册回调函数：使用wkupct\u register\u callback（）
Enable IRQ for wakeup: wkupct_enable_irq(0x40000, 0x40000, 1, 0); // i.e. P2_2, active low for P2_2, 1 event, debouncing time = 0ms


再次感谢，
CD

Hi CD,

Yes, thats right, register your callback (wkupct_register_callback(your function)) and enable the pins and the polarity to the appropriate pin (wkupct_enable_irq()).

Thanks MT_dialog

Hi MT,

Thank you very much for your confirmation.
Now, it's clear!!

Thanks a lot,
CD
