something like TI debug waveform?

Hi!How does ST ecosystem helps MCU debugging? TI has their debug waveform which seems being liked by many engineers.

[STM32G0] Analog watchdog interrupt always activated even when the voltage in the guarded window

Hello,I am experiencing the AWD interrupt always being activated when using the analog watchdog on the STM32G0B0 to guard channel 0. Here is my configuration:systemclock = 64MHz   ADC ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4   Resolution = 12B   Con...

Interrupts in EEPROM emulation(AN3969)

I'm trying to implement "AN3969 EEPROM emulation in STM32F40x/STM32F41x microcontrollers" on STM32F407.According to the documentation, "Interrupt servicing during program/erase is possible".However, when actually installed, interrupts stop completely...

SPI without CS

I am using TLC5941 Led driver and it communicates with Nucleo-U575ZI-Q and SPI on TLC using three wires only clock, MOSI and MISO and there is no CSso I have an issue with connection so my question is:Is there a way to make SPI on stm32 without CS?

Nucleo F401R1 - Timer interrupt and lockup

 I am using timer interrupts to read 2 optical encoders connected to 2 motors. Everything seems to run fine for a while, then I get a hard lockup and everything stops. The time can be 5 minutes or 2.5 hours. I installed and setup watchdog and when it...

For STM32L4S5, how to access the calibration register and how to calculate what values to store in that register? We're having a problem with the calibration of the real-time clock. It's significantly off-time over a period of several days.

We believe there is a register setting to calibrate it, how can we debug this issue please? What are the steps to calculate the calibration register value and how do we get them into the register?

Can we distinguish which ADC channel has done the conversion when using multichannel interrupt method ADC??

NUCLEO-C031 Pin Change interrupt not firing

[Update]Seems you can't mix C and C++ files easily, so I converted the main file to C and everything works fine. [/update]I am attempting to do what I thought would be a simple pin change interrupt on PB0.I set up the pin change in HAL and it works, ...
