I've been slowly learning how to develop apps using STM32L4R9 and STM32F4xx MCUs. I just went through a really painful experience trying to develop an app that talks to a UART device and logs data to the SD card on the STM32L4R9-Discovery board that...
The access time of the FMC is not the whole equation, I need to include the delays introduced by having to go across domains and buses. Back to back reads or writes would shine more light on this for me. Or possibly a read followed by write so that ...
Hi community,I'm developing on STM32F7, it accesses the external device via FMC.Then it can read the external device's register, but it cannot write to the register.The external device expects EXTMODE ModeA timing like the following figure. Reference...
Hello,RM0394 in 16.3 ADC implementation mentions "SMPPLUS control" for ADC2 on STM32L412. I do not find any other expalantion.Thanks
I'm new with the STM32F767ZI (Nucleo board) and tried to write a SPI driver with DMA access.It works so far, but I have some stupid things on my log, I can't interprete. Is anybody there, who knows what there is going wrong?I'd like to send three byt...
Hello,I'm a new new member and user of STM32 microcontrollers. I've just started using a bluepill STM32F103C8T6 microcontroller and I'm trying to set up a simple SPI communication.At the moment I do not have slaves, only a master (the STM32), and I'm...
Hi,If I am starting with 120 MHz system clock and want the master timer to generate a 60 MHz PWM waveform and I want the second timer to generate an in-phase 8 MHz PWM waveform I must clock the second timer with 120 MHz (as 60 MHz isn't divisible by ...
Hi, I've 2 Nucleo boards (Edit: Nucleo -G431RB )to communicate between FDCAN. I create a project using CUBEMX. Default FDCAN RX/TX is PA11/PA12. and I have no problem getting it work. All worked fine. But I also need USB so I moved FDCAN Pins to PB9/...
Hi, I need to count the number of pulses from a device which is connected to STM32 IC. For counting pulses i have activated the interrupt using Timer 2 and i have used channel 1 (PA0).The parameter setting for enabling and using Timer2 in CUBEMX is g...
If the bit in Pending Register of STM32 is not cleared.Will interrupts trigger all the time?Will the Interrupt service function always run?
