Hello,I have question about QSPI on stm32F446.I want to connect serial flash with QSPI.there are 2 banks on QSPI.When I try to find some example on QSPI, they were all used QSPI bank1 connected to s/f memory. But when I check pin connections on QSPI ...
I want to interface Stm32 MCU with a NXP MCU over SPI protocol.Does anyone have done that before?? If yes can you please tell me how it can be done? I have already used St and nxp mcus separately and now my application requires both of them together....
Hello ST Community,I am using RTC backup register of STM32F746ZG for saving some accumulating data.So i'm afraid of situation when i start write operation and in the same time the VDD power is disabled.Couldn't find any information about this, so i a...
Bottom of page 299 in the H7 Ref Manual says pretty clearly that "In Standby, all I/O pins are high impedance without pull" except for a few WKUPs and Reset. Okay, this sounds like I'm out of luck for holding peripherals in low power states. But the...
I'm looking for some more information when it comes to the STM32 OctoSPI support for Regular command versus HyperBus protocols when it comes to interfacing with an external PSRAM in Memory Mapped mode.We are considering a ISSI OctaRAM part vs HyperRA...
I'd like to know the difference between injected channel worked on discontinuous mode or not.it seems like the same result. if I have 3 channel to convert triggered by a signal.Sequence length is 3.1st trigger : channel 1 is converterd.2st trigger : ...
Hello, for my personnal project I use a stm32F98 with the CAN peripheral activated.First of all I have an issue with the configuraiton gave in the stm32f0_firmware example but if I set the GPIO_InitStruct.Pull to GPIO_NOPULL, I cannot have the INAK b...
Controller : STM32L031F6P7 custom board.I2C stops working after exactly 1 minute 6 seconds? I can replicate this every time.When it stops working, i cannot reset the i2c pheriperal in any way i have found in this forum.These are attempts i already tr...
