Deepsleep

[kissste]

Hi there,

I'm playing with deepsleep, using the lastest version of @pvvx SDK 3.5.2 from github

1/ this work well - by timer
deepsleep_ex(DSLEEP_WAKEUP_BY_TIMER, sleep_ms);

with the exception of the LED shining....

2/ but this one DSLEEP_WAKEUP_BY_GPIO | DSLEEP_WAKEUP_BY_TIMER appears to hanging forever
deepsleep_ex(DSLEEP_WAKEUP_BY_GPIO | DSLEEP_WAKEUP_BY_TIMER, sleep_ms);

Any suggestions?

Thank you

void fATDS(int argc, char *argv[]) // Deep sleep
{
printf("DS0\n");
uint32 sleep_ms = 10000;
if(argc > 1) sleep_ms = atoi(argv[1]);
#if 1
printf("DS1: %d\n", sleep_ms);
// turn off log uart
sys_log_uart_off();
// initialize wakeup pin at PB_1
gpio_t gpio_wake;
gpio_init(&gpio_wake, PB_1);
gpio_dir(&gpio_wake, PIN_INPUT);
gpio_mode(&gpio_wake, PullDown);

// enter deep sleep
deepsleep_ex(DSLEEP_WAKEUP_BY_GPIO | DSLEEP_WAKEUP_BY_TIMER, sleep_ms);
#else
printf("DS2: %d\n", sleep_ms);
deepsleep_ex(DSLEEP_WAKEUP_BY_TIMER, sleep_ms);
#endif
}

Pin чипа PB_0 включен к светодиоду, а при входе в режим deep_sleep отключается внутреннее питание на I/O и на выводе получается около 1В - через внутренний диод чипа, в отключенное питание, не в полную силу загорается заботливо включенный китайцами светодиод и жрет к 0.5 mA...
Чтобы его отключить требуется отломать крышку модуля...

gpio_wake - IOports и pinmap RTL8710AF -> WKDT ?

// deep sleep can only be waked up by GPIOB_1 and GTimer
#define GPIO_WAKE_PIN PB_1

I have tried PB_0 too, does not work.

//does not work - even the timer portion of this does not work, does not wake up after sleep_ms
deepsleep_ex(DSLEEP_WAKEUP_BY_GPIO | DSLEEP_WAKEUP_BY_TIMER, sleep_ms);

//works
deepsleep_ex(DSLEEP_WAKEUP_BY_TIMER, sleep_ms);

//does not work
deepsleep_ex(DSLEEP_WAKEUP_BY_GPIO, sleep_ms);

All Work. PB_1 set low, before launching Deep-Sleep!

Works! Thank you very much.
