STM32 MCUs Products

For the stm32h743 I use the STM32H7 single-core self-test library. All tests pass, except TM9. Documentation says TM9 implements the test of the Arm Cortex-M7 DSP functions. What can be the reason it fails? DMA is disabled.

HAL_UART_Receive_IT skips bytes from RN2483 lorawan module

Hi,I want to use a lorawan device with my stm32 l053r8 microcontroller.To do this, i reset the lora module initially. In Response I should get the firmware version of the device, but i receive only parts of the string, e.g. some bytes between the st...

How to send TSC data from STM32L476 rg into a file on a computer along with time stamp

I'm trying to use the TSC on the STM32L476rg board. I've been able to view the value on the watch window on Keil and using stmstudio. Now how do I store the values obtained into a text file on my computer along with the timestamp of each reading?

Hey everyone we are working on a sewage monitoring system project based on IOT.Can you suggest a suitable microcontroller board for the same?

I am working on STM32G030 series microcontrollers & I am using external crystal as clock source (HSE). But as per AN2867 Application note(page13) gain margin ratio should be greater than 5, But I am not able to get it above 2.9. What should I do?

STM32G030C8T6 has maximum critical crystal transconductance (gm) is 1.5 mA/V.Crystal specifications that are mentioned in application note(page14) gmcrit = 0.23 mA/V with this gain margin > 5. But I checked many crystals datasheet but I am not able t...

SPI slave send and receive 1..n bytes - what if less bytes are sent?

Hi,i want to utilize an unknown number of SPI slaves which will send and receive e.g. a byte of data each. patching them together has to be as easy as plugging an ethernet cable BUT some data is used by multiple slaves.Let's say I have a maximum of 3...
