STM32 MCUs Products

I use a STM32L151 in a battery application, i have to measure VCC. To do this exactly i try to read the Vrefint-calibration Value, stored at 0x1ff80078/9 (STM32L151 Datasheet pg. 56) But if i try to access to this address via a pointer, i read 0x0.

Memory Dump with STM32CubeIDE shows also 0x0 at this addess. The Errata shows no entry to this problem.uint32_t* ptr = 0x1FF80078;VREFINT_CAL_VAL = *ptr;Is it a typo in the dataheet?

Some questions about using float, snprintf, sprtinf

I would like to advise you, I create software for the STM32L151C8 microcontroller that will control the LCD segment display via the I2C PCF85176 driverDesign:- battery powered- configurable by the attached bluetooth module and keeping configuration v...

What is Actually ADC sampling rate. Suppose i want to trigger the adc at sampling rate of 1Msps. i would trigger the adc using timer update event that would over flow after every 1 usec. But in the parameter setting using cube mx for adc has one option

of sampling time in terms of cycles. what this sampling time corresponds to. I mean is this the actual rate at which the adc samples the input signal. If this is Sampling rate of ADC. then using Timer update event which i set for every 1hmz is relate...

hi this is karthik from india i am using STM32F030C6 MCU i need a suggestion from u i am stuckup calculating AC vrms voltage and DC current at different GPIO pins which has ADC also available as analog mode while i am using multi channel garbage

Is it necessary to test all GPIO for class B compliance?

Hi Is it necessary to test all GPIO(output ports)(STM32G070KB)for class B compliance? writing data to outputs ports make problem in my product.

What time in UTC, the workshop will begin tomorrow, 9:30 UTC, or else?

Which database can we use in stm32 cortex m0 controller in order to use it in offline mode?

The SWD and Trace ports on STM32H7

The SWD port appears to be dedicated to CM7 core. My first question is whether it can be dedicated to CM4 and second question is how to use Trace port on CM4?Thanks

please give suggestion to measure AC(vrms) at GPIO pin and DC current at another GPIOpin using ADC multi channel simultaneously in STM32 microcontroller please i need detail explanation about this

I am using STM32F401RB MCU
