STM32G431 TS_CAL2 temperature

HI

At what temperature the TS_CAL2 value for the STM32G431 is detected?

In the datasheet it is reported 130 degrees while in the library "stm32g4xx_ll_adc.h" TEMPSENSOR_CAL2_TEMP is 110 degrees

Thanks

Hello,

Correct answer is 130°C

You're probably using STM32G4 firmware package below version 1.5.0, where it is updated.

Has this been fixed? It appears to still be incorrectly specified as 110C in STM32Cube FW_G4 V1.6.0

See https://github.com/STMicroelectronics/stm32g4xx_hal_driver/issues/20

I don't think it has been fixed.. Had to hardcode it to 130UL myself..

Right, thanks,

For the G431 I'm using STM32CubeIDE Version 1.7.0 with STM32Cube FW_G4 V1.4.0 because using STM32CubeIDE Version 1.8.0 with STM32Cube FW_G4 V1.5.0 and the same code the interrupts are not generated or intercepted and I don't understand why

Hi @doubleset​ ,

New versions for STM32CubeIDE & STM32CUbeMX are currently available. If the issue with interrupts you introduced previously is still there, please describe it with more details in a new post. It will be helpful in order to anlayze & fix it.
