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...
my pagesize is 256 bytes, and 90k is about 351 pages for(i = 0; i < pages; i++) { W25qxx_ReadPage((uint8_t *)u32_databuf, EXT_FLASH_ADDR_APP_START + i,0, w25qxx.PageSize); ProgramInternalFlash(APP_BASE_ADDR + i * w25qxx.PageSize, u32_databuf,...
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.
For OSC i am using 32.768khz and caps 10pF, but output is not coming. so please give me suggestions for hardware & software chages to work 32.768khz clock work.
Hi everyone,I am working with a STM32G070 to control a small robot. I am currently coding a calibration function for the different motors of the robot and I would like to store the result of the calibration in the flash memory of the MCU, so that I d...
Hi,how can i output the reference Voltage to PB0 or B1 at a STM32L1(51RCT6A) µC ?I've enable the "Voltage reference out" at cubeMX.At the RM0038 Figure 28, is see a second switch to PB0 or PB1, how i can enable that?THX
