Read temperature calibration values from MC register

[hazin]

Steps to read the temperature calibration values from the stm32l152rc

[waclawek.jan]

In the datasheet for your particular STM32 model, look up TS_CAL1 and TS_CAL2 addresses, and then read a halfword from that address.

Maybe related to this thread?

Why is there two addresses corresponding to CAL1 and CAL2

[waclawek.jan]

Each TS_CALx is 16-bit so it occupies two bytes.

Can I get an example souce code to read TS_CAL1 and TS_CAL2 addresses.

[waclawek.jan]

uint16_t cal1, cal2; 

cal1 = *(uint16_t*)TEMPSENSOR_CAL1_ADDR_CMSIS;
cal2 = *(uint16_t*)TEMPSENSOR_CAL2_ADDR_CMSIS;

TEMPSENSOR_CAL1_ADDR_CMSIS and TEMPSENSOR_CAL2_ADDR_CMSIS are defined in the CMSIS-mandated device header.

Thank You!!:hundred_points:

Different VREF+/VDDA voltage than 3.0V, or some other reason.
