memory partitioning and version switching.

hello, my project was to do a over the air update, looking for various strategies and I found one in the vector website. https://www.vector.com/int/en/products/application-areas/embedded-software/embedded-trends/ota-update-approaches/#c230972This met...

X-NUCLEO-S2868A2 S2LP SIGFOX problem with use of the flash instead of the eeprom for saving the ID and PAC credentials

Hi everyone,I'm doing tests with sigfox using the deboboad X-NUCLEO-S2868A2, and with the example everything works.However in the final product I will not have an EEprom where to store the sigfox credentials (id and Pac) and therefore I would like to...

Out of the blue my project started giving me the message "Break at address "0xfffffffe" with no debug information available, or outside of program code" whenever I try to debug.

It seems to start in main and debug just fine after this so I have just kept working, but I'm worried that there is something wrong that is going to byte me in the future. Should I be worried?

Am I understanding the SysTick timer correctly?

Here SysTick_Config(16 000 000) takes one second to count down from 16 000 000 to zero?That is, one tick has a duration of 1/16 000 000==62.5 ns ?0.0000000625(one tick time) *16 000 000 ticks== 1 secondCorrectly?At the end of each count, an interrupt...

How change the PWM polarity of CH2N during runtime ?

I have set Timer 8 to PWM Generation CH2 CH2N. Based on the value read by the ADC, I want to change the polarity of both CH2 and CH2N. I have found that using __HAL_TIM_SET_CAPTUREPOLARITY, I could change the polarity of CH2 but the polarity of CH1N ...

What is the best IDE / tool chain for an STM32 rookie?

My background is in hardware, but I have extensive experience writing "bare metal" code (C) for 8-bit MCUs, mostly for AVRs. In the past, I have used AVR Studio (now Microchip Studio), starting with version 4.18 down to present versions. Tool chain...

nucleo-f439zi pwm not working?

I am trying to configure PWMs on the user leds uisng the nucleo-f4329zi board (default preconfigured project) and the visual configuration of the STM32CubeIDE, but for some reason some PWM are not working.My setup for all all PWM (aside from default ...

What is the cause of STM32 shortage? When will STM32 processors be available as normal? The pricing and delivery times are ridiclous now.
