Use tabs instead of spaces when generating files in cubemx

Hi, I recently installed the cubemx software, and while learning the program I saw in the code files that the indentation was space based and not tabs based. Is there any option to change the indentation style? I can't find any option like this in th...

How mix EVAL6470H-DISC example design code (IAR) with STM32CubeMX generated code

Dear All,I've loaded inside IAR the example design that came with this board after installing the stsw-spin004 library.Now I've to add to this board an external rotary encoder, so I'll use the TIM4 because related pins are not used inside this board....

ARM Cortex M4., How can i know how many bytes a variable is taking to store the value?

Hi I have configured my ADC as Input 10 bit and i would like to sample the signal from accelerometer at 20KHz. I would like to know how much of address space is the memory taking to store these? Is the memory taking 1 byte, 2 byte, 4 byte ? How can I...

Enable SRAM parity check

How can I enable the parity check in the SRAM 2 of the STM32L4?Is there a HAL function?

STM32H753 initialization failure when in contact with the chip physically

Our application is to use STM32H7 to finish the communication to FPGA/LAN9252/PHY/SDRAM. The power supply of VDD3V3 is generated by an LDO with Tr = 2.4ms. During the test, we found that if we get in contact with STM32H7 (not pins but the package) b...

STM32L0 - Microseconds delay function

Hi everyone!I am using a STM32L0 board and I need to read data from a sensor. To be able to do this, I need a microsecond delay function, but I could not find any way to achieve this.I need some help! Thank you!

On an STM32H7, which clock frequency determines Flash wait states?

In RM0433 revision 5 section 3.3.8, the following text appears: “To correctly read data from Flash memory, the number of wait states (LATENCY) must be correctly programmed in the Flash access control register (FLASH_ACR) according to the embedded Fla...

Hi What is the difference between F series microcontrollers and H microcontrollers? Which series is better to start learning?

Proximity sensor and STM32F030R8T6 for RPM Measurement

Greetings Friends.I want to interface proximity sensor with STM32F030R8T6 for measurement of RPM. I need guidance on how to make it possible and easy with out the use of PLL ic .I was thinking of interfacing proxy sensor output to STM32 pin and take ...

STM32 signalling for RS-485 - DE?

We are using the STM32F091RC to setup an RS-485 interface with the TI SN65HVD11. How do we connect to the DE control signal for the SN65HVD11? I have currently selected USART3 -R - PC5 (RX)D - PC4 (TX)DE - PB1 (RTS) Is this correct? Also what is CK_R...
