I am trying to do RTC wakeup interrupt using STM32L412RBT6 microcomtroller in baremetal c, but the interrupt is not firing, below mentioning my code. int main(void) { LedConfig(); Tim6Config(); RTC_ClockConfig(); RTC_Init(); /* Loop forever */ while(1) { GPIOB->BSRR |= (1U...
Then in FreeRTOSConfig.h define the configPRE_SLEEP_PROCESSING( xModifiableIdleTime ); macro to set your RTC wakeup interrupt for the correct time [1], enter a deep sleep mode [2], and set xModifiableIdleTime to 0 [3].[1] The time to sleep, in ticks, is contained in the x...

這個RTC WakeUp 已經在 GF8100 platform 上 with Ubnutu 8.04.01 測試 OK!! 我們可以透過 ACPI 提供的 interface,設置 RTC alarm,如此在 alarm 發出 IRQ 時,ACPI 就會 resume system。EPC 中的 genrtc module 並不支援 alarm interrupt。如果手動加入 rtc module,雖然它有支援 alarm interrupt,但是透過 rtc modu...
RTC_WAKEUP android 定时唤醒 启用唤醒定时器 1.实验目的 为什么要睡眠? Zigbee 的特点就是远距离低功耗的无线传输设备,节点模块闲时可以进入睡眠模式,在需要传输数据时候进行唤醒,能进一步节省电量。 掌握几种系统电源模式的基本设置及切换。 系统电源有以下几种管理模式:全功能模式,高频晶振( 16M 或者 32M )和低频...

C5515的datasheet, system user guide, RTC user guide 以及网站上, 都提及到RTC only模式下, 如果要唤醒系统,需要在wakeup pin上面加高电平, 脉冲时间需要超过30.5us. 唤醒系统的方式包括, 外部wakeup pin手工置高电平, RTC Alarm 和RTC periodic interrupt 三种方式. ...
