I try implement a function to detect how the MCU start from, reset from watchdog or hardfault or recycle power.Watchdog reset, if the code goes to dead loop, it will trigger WD, but I have no good idea how to capture it.Recycle power, I can use PVD_I...
Hello,I've not much experience with all STM timer modes. I have a DDS-based freq source which produces meander wave. On base of this src I want to produce PWM signal using STM timer. As I understand, a regular way to do it is to pass the DDS src as e...
Hello, the datasheet of STM32F030C8 say to use 100nF and 4,7uF capacitor. I have a doubt about the type of this 4,7uF capacitor. I have to use a ceramic, tantalum ou electrolytic? If I use a ceramic, this need a specific model or any ceramic capacito...
hello all, I try to use the arm lib to make a FFt but I d'ont understand it well and so I can't. I need some help on it.first, I make a acquisition of a signal (form a generator).the signal is at 30KHz. I sample with the STM32 at 1MHz. I use a DMA to...
Hi all:I have an STM32F407 and I am trying to implement a CAN bus software driver.I want to know if there has been a Rx FIFO overrun, which would mean that the firmware is too slow and is not seeing all received messages. Each hardware Rx FIFO can on...
Hello,I am currently utilizing STM32F205xxxx chips on several board designs, but may need to transition to other chips within the STM32F207/15/17 family due to procurement issues. I wanted to confirm the pin-to-pin, hardware, and software compatibili...
Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual sh...

Hello! I am trying to interface IC max7219 (Serial interfaced led driver) with STM32F401RE through SPI communication.I am finding irregular functionality of SPI enable (CS ) is active high when communication is happening & also MOSI data is incorr...
STM32F469I discovery board.How to use internal flash memory address for a particular variables? it's possible ?I am struggled with this issue.i am beginner of stm32. help me.
