[Edit: transferred from stm32duino/STM32RTC]
Hello,
I recently seen the board library was updated some days ago and the HAL feature was newly implemented.
I thought that with the new master branch board platform the new library will work, so with my Nucleo-F411RE I tried to operate the new library.
It worked without I2C. I use D14/D15(I2C1) and if I connect any I2C device, then the MCU goes to forever sleep(all codes are stopped).
This code shows:
#include <Wire.h>
#include <STM32RTC.h>
STM32RTC& rtc = STM32RTC::getInstance();
void setup() {
// put your setup code here, to run once:
rtc.setClockSource(STM32RTC::LSE_CLOCK);
rtc.begin(false); // initialize RTC 24H format
if (!rtc.isTimeSet()) {
rtc.setTime(0, 0, 0);
rtc.setDate(1, 1, 19); // fallback
}
pinMode(LED_BUILTIN, OUTPUT);
Wire.begin();
Wire.beginTransmission(0x50);
Wire.write(0);
Wire.endTransmission();
}
void loop() {
// put your main code here, to run repeatedly:
delay(500);
digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
}
0x50 means the EEPROM device and I just wrote a waste data to the line, so there must be no problem.
However If I use this code with any I2C device connected, F411RE just halts and not respond for anything(interrupts are all stopped too).
Couldn't be the new library used yet? Or is this a bug?
Thank you.
