defined things called "undeclared"

Hi, my processor is STM32L010C6TX. I added function to my project to use microsecond But " DWT" "CTRL" etc. It says not defined. However, they are all in the "core_cm4.h" library. This library is in Drivers-> CMSIS->Include. why doesn't it call this ...

8 timers of 2 Stm32f7 Synchronization

Hello everyone,I have used 2 Stm32f7 nucleo boards to read the data of 8 incremental encoders. for this purpose, I have used timers. I can read the data of encoders correctly but there is a little bit time difference between timers. it means I need t...

Hello everyone, I'm new to STM and I would like to know if it is possible, to draw rectangles on PC Window like a rectangle or cricle on the symbols or anything. Are there some libraries to draw stuff on PC Window?

STM32H747I LQFP176 Package Pin-out mistake in datasheet

The LQFP176 Pin-out at Page no.76 of STM32H747I in datasheet (DS12930 Rev 1) has a mistake at pins 158 & 159.Pin 158 has been mentioned as VSS instead of PG14.Pin 159 has been mentioned as PG14 instead of VSS.But at Page no.86 these 2 pin functions a...

How to supply an isolated CAN transceiver from STSPIN32G4?

Dear all,I'm planning to use an STSPIN32G4. Our product needs an isolated CAN transceiver. The EVSPIN32G4 offers a slot for a TCAN330, but this transceiver is not isolated. I could use an LTM2889, but it needs 140mA (225mA max) to drive the bus in do...

I need to transmit two buffer trought HAL_UART_Transimit_DMA. I wrote in the code two consecutive command to do it but when I run the code, HAL_UART_Transimit_DMA do not return HAL_OK. It return HAL_OK only in debug mode stepping with F6. Why?

uint8_t slv_add[] = {0xF1, 0x0A, 0x00, 0x57, 0x53};                            if(HAL_UART_Transmit_DMA(&huart1, &slv_add, (sizeof(slv_add)/sizeof((slv_add)))) != HAL_OK)Error_Handler();uint8_t cell_sel[] = {0x91, 0x00, 0x0D, 0x06, 0xA8, 0x6E};      ...

Where can find the MTBF/FIT data of STM32L071CBT6?

STM32L422CB, low power consumption in capacitive proximity by single channel wake up source.

Dear All,We are planning to use STM32L422CB MCU in our application, but for low power consumption we are expecting capacitive proximity by signle channel or simple wake up by proximity.Somehow, we are not able to find out exact current in low power s...
