Resolved! Potential bug in CubeMX for STM32U5-series without SMPS?
Hi!I am using a STM32U599VJT6 device without SMPS but getting this message when generating code: What is supposed to be configured?Thanks in advance
M7 with 4xRAM ICs over FMC
Hi,We have a question about a system design we would like to implement for our product.We are working with the STMF32F723 MCU and are developing our own HW. We need 216MByte of RAM for our application and would like to implement it with the functiona...
STM32L452 Temperature
Hi,How can we extract a correct reading of the internal temperature of the STM32L452 in degree C?We currently read a number '141' but this is clearly not the CPU temperature which should be 22-28oCWe have followed the general app note on temperature ...
H7 single-core vs. dual-core
Hi,I am considering which solution to go for in a new product. To start with, I am going for a 480 MHz STM32H7 with high-resolution timer (HRTIM) for some quick PWM regulation. The regulation feedback is supposed to come from a fast ADC, so I need to...
Resolved! CAN FD multiple MCUs
I am trying to connect 2 NUCLEO-G0B1RET6 boards,using CAN FD. I previously did it using CAN, But now i am trying to connect these boards using CAN FD. So far no success,I want to know if it is possible to do it using CANFD.Kindly help me in this rega...
program flash of STM32H745 and execute code from same bank?
Hello,my CPU is a STM32H745. I want to flash data into both banks (bank 1, sector 2-7, complete bank 2, while the code runs from the first bank, sector 0+1.I'm using the given HAL-drivers stm32h7xx_hal_flash.c and stm32h7xx_hal_flash_ex.c and found a...
Resolved! USB host on STM32L475 board with FATFS
Hi! Hope everyone are doing well! I currently encounter a problem and can't solve it. I want to write some pieces of data into a file in a usb-disk and now the Appli_state is constantly idle even I connect the USB-Disk already.This is a test demo cod...
Resolved! STM32L4 - Could state of JTDI pin affect switch-over to SWD?
I am using a STM32L471 MCU in a design that may be flashed with new firmware in situ. I'm using SWD as the interface, so the two unneeded JTAG pins (JTDI and JTDO) are used for other purposes. According to the reference manual, JTAG is activated by d...
STM32F746: behaviour of from Timer to Memory DMA transfer when timer event occurs
Hi everyone Question: suppose one sets up a DMA transfer from a Timer1 register to memory so that it gets executed when timer event is raised. What happens first:the peripheral to memory DMA transfer is executed ?or the Timer registers are updated?...
