Hello!I have a new project with a STM32F407VET6 and a STM32F103xxx over a RJ45 Jack with I2C.i worked a lot of time with I2C EEPROMs and it works fine, but my communication between the 2 STM's are horrible, or i am too confused.i found the tutorial o...
Hi,I'm using H723 for programming,and TCM ram is in use.when compiler optimization feature is on,code can not work.Is it not possible to use TCM while turning on optimization? or requires some setup? Regards,Binge
Hello everyone,I want to use the MT46V64M8P-5B:J 64Mx8 SDRAM by Micron with a STM32F745IET6 microcontroller.I'm configuring the peripheral on stm32IDE and it looks fine, the configurator automatically set PG8 as clock signal. Still, the SDRAM require...
For producing 4KHz resonant frequency sound from a buzzer using 32KHz system clock, what should be the Prescaler value and Period(ARR)? Is there any rules for defining these values?
Hello friends, i have the following setup:STM32H725ZGT6 on a selfmade board. STM32 CubeMX (default program with HSI clock and without any other peripherals). Keil µVision 5.23ULINK2 Debugger problem:I can program the controller ("verify successfull" ...
Hello.I'm trying to wakeup the STM32U5 controller (U575ZI Nucleo board) when a byte is received using the LPUART.I'm using the LSE clock for the LPUART. Without entering the stop mode, the LPUART interrupt is triggered whenever a byte is received. Th...
When I downloaded applicaton into flash, I found that it will respond my cmd code if I send cmd code immediately after NRST changing from 0 to 1.If although I choose 'Boot0(pin) = 1和Boot1(pin) = 0' to flash mode, the stm32f103 will also enter system...
how to tell the stm32(f103c8t6) chip between the fake and the original
Hello, I am trying to install FileX + LevelX in an stm32h7 microcontroller using a nor custom driver. I do have in my hardware an AT45DB641 NOR memory. I am working it as an stand alone and also with fault tolerant enable. My flash chip does have 40...
Hello, Is there an option to use with Nucleo-L152RE as Power Delivery CC line sniffer and decoder?As far as I know to allow to sniffer cc line protocol it should have the ability to use Manchester decoder.Thanks,
