STM32 MCU UART TX current

I am connecting the STM32L4 MCU UART to silicon labs IC CP2105 (UART to USB converter). The UART to USB bridge is bus powered from the type C connector and the STM32 is separately powered from the battery. When the CP2105 is in off state ( No USB ca...

We are using STM32G431RBT6 Break Input .I have configured the Break input and it is working fine .When Break Input is Low ,the PWM is ON. After Break input is High ,the PWM is OFF ,Now if we give Low to the Break input No PWMs are Generated.

Bus Fault when PUSH instruction is execute when calling nonsecure entry function

I am currently working on a project using STM32U575 with Trust Zone activated. I am using IAR compiler.I am facing an issue where Bus Fault is triggered whenever a PUSH isntruction is executed during the call to a cmse_nonsecure_entry functionBFAR ad...

It seems that the Cortex-M3/M4 controllers with EEPROM are being phased out. Is there a reason for this and what are the recommended alternatives?

what is pwm idle state high and low side. how to select this option?

Problem with a STM32F446 nucleo board, firmware doesn't work properly

I'm currently having a problem with a STM32F446 nucleo board, I'm trying to write a Firmware that takes in data from some sensors connected to the board (velocity, ecc) and prints it every second. The code I wrote respects the specification, but the ...

Resolved! may i know how to download stm32f429zi controller examples. can you please provide any link regarding examples.

i'm reading temp sensor value and store to SD card and my question is, it debugging successfully & if i run for 5 times only, it reads output from a sensor and storing to SD card 2.if I flash to the controller without Debugging, text file is not generate
