I would like PIO support. #70
Description

My config
[platformio]
default_envs = blackpill_f103c8
[env:blackpill_f103c8]
platform = ststm32
board = blackpill_f103c8
framework = arduino
lib_deps =
https://github.com/stm32duino/STM32LowPower
https://github.com/stm32duino/STM32RTC
My code
#include <Arduino.h>
#include "STM32LowPower.h"
void setup() {
LowPower.begin();
Serial.begin(115200);
Serial.println("serial (same as 1)");
Serial.println("*****");
}
void loop() {
unsigned long nowMillis = millis();
Serial.println(nowMillis);
Serial.println("serial printing");
Serial.flush();
for(int i=0;i<20;i++) LowPower.deepSleep(1000);
//for(int i=0;i<10;i++) LowPower.sleep(1000);
//for(int i=0;i<5;i++) LowPower.idle(1000);
//delay(1000);
}
Problem
My understanding is that the above code sleeps 1000ms 20 times.
However, it actually sleeps only 250 milliseconds.
Standard output scrolls up at a high speed.
Is the frequency of the crystal involved?
