cast conversion issue when _LL_RTC_CONVERT_BCD2BIN macro is used

[jealcuna]

I am using stm32cube ide 1.7.0 and when I use the macro _LL_RTC_CONVERT_BCD2BIN a warning rise. I have wconversion warning flag enable, also, when I call the macro y use a uint8_t type data. I have -o2 optimization.

In the picture attached VALUE is replaced by a uint8_t variable with a valir bcd number.

This is the code which is calling the macro:

ptm.tm_hour = (int)__LL_RTC_CONVERT_BCD2BIN((uint8_t)__LL_RTC_GET_HOUR(time_bcd));

[jealcuna]

A workaround for this is replace the line with: #define __LL_RTC_CONVERT_BCD2BIN(VALUE) (uint8_t)((((uint8_t)((VALUE) & (uint8_t)0xF0) >> (uint8_t)0x04) * (uint8_t)10) + ((VALUE) & (uint8_t)0x0F))

Hi @jealcuna,

I hope you are fine. We tried to reproduce the problem you reported, with no success. Below the environment configuration used:

• STM32CubeG0 v1.6.1
• Cube IDE v1.9.0
• Optimization level -O2
• Compilation flags -Wall and -Wconversion enabled

Would you mind precising the types of variables time_bcd and ptm.tm_hour used in your code?

Thanks,
