用nRF52的RTC实现万年历 nRF52系列芯片内部有3个RTC,其中RTC0是给协议栈softdevice用,RTC1分配给 App timer用,剩下的RTC2可以用来实现万年历功能。 代码基于SDK15.0,在BLE_APP_UART例程上进行添加和修改: 1) 在工程Application目录添加ble_calendar.c 并包含对应头文件和目录; 2) 详细代码参看: https://pan.b...
This example enables the RTC timer to periodically trigger SAADC sampling. RTC is chosen here instead of TIMER because it is low power. The example samples on a single input pin, the AIN0, which maps to physical pin P0.02 on the nRF52832/nRF52840 ICs. ...

For example, Teensy 4.x, with super-high clock frequency of 600MHz and Timer1 and Timer3 clock of 150MHz, the maximum interval / frequency is only 55922.3467 us / 17.881939 Hz. This Teensy_TimerInterrupt library will provide you up to 16 super-long (ulong millisecs) ISR Timers for each...
I have used the dual role BLE uart example and these are my findings: -to enter low power mode you have to add delay() in the main loop , the longest the milliseconds the lowest the power drain. -all Ble central related functions are taking quite a bit of mA ...
