Hello,what is the value of USART->DR (RDR) is read twice after receiving a byte? E.g.Byte 0xFF received, RXNE flag set.DR is read into variable, RXNE is cleared, the variable contains 0xFFDR is read into variable, the variable contains ?Does the DR h...
The CAN bus transmit some raw data at 500Kbits/sec and is transferred via transciever to pins PB8(Rx) and PB9(Tx).I tried to configure the followed values from the cubeMx platform (since my CLK on APB1 is 42MHz): prescalar=6, TimeSeg1 = CAN_BS1_11TQ,...
Hi, I'm using STM32F373 for my project. When I'm using core freq >=36MHz everything is fine. But I need to decrease core freq for power consumption. When I run project with 12/24MHz Hard Fault is occurred in 1-5 secconds. Times is randoms. (Of course...
I have STM32L073RZ. I'd like to load my code through the USB connection (PA11 and PA12 pins). When I use the Nucelo Board NUCLEO-L073RZ the Peripheral Manager detects the board as "STMicroelectronics STLink Virtual COM Port COM6)". I would like to by...
Hey guys, setting up External GPIO interrupts I wanted to setup PA0, PB4, and PC6 as GPIO interrupt. The PB4 works perfectly it goes into the IRQ handler no problem, howeverPA0 and PC6 have similar issues for some reason they dont want to call the IR...
Hello,I try to implement an FFT on the STM32F401CE controller. I followed a tutorial from youtube (https://www.youtube.com/watch?v=vCcALaGNlyw). It mainly consists of including arm_math.h and libarm_cortexM4lf_math.a. I succeeded in doing so and comp...
I have a custom board with SWO pins for STM32 firmware (but I don't have the RESET pin)I was planning to update my board remotely with ST-Link and raspberry piBut I found out too late that STM32CubeProgrammer does not support ARMI tried to use ST-Lin...
STM32L051C8, use standby mode; exit is equivalent to restart; whether there is a flag bit to determine the type of restart; for example, power-on restart, watchdog restart, low-power wake-up can be distinguished; whether it can distinguish the standb...
0I am working with SPI on STM32F429 to write data on MX25V1006F flash memory. I am not using cubeMX library.My problem is that it works for a while and then suddenly it doesn't work. I have replaced MCU several times but I faced same problem again an...
