Resolved! Could anyone help me calculate TIM frequency?
Hello everyone,I'm using TIM3 on my Nucleo H745. If it's correct this TIM gets fed from the CPU clock, so it runs at 480MHz. That's what I thought at least.Using these settings;htim3.Init.Prescaler = 48000;htim3.Init.Period = 10000;To my calculations...
How to implement the TIM_IRQHandler when using other classes
I'm trying to make a scheduler and everything seems to be ready, now the final step is add the proper function to the IRQ_Handler. This is where my problem starts. At default this uses a extern tim object from the main.c. I removed it there and put i...
I didn't get the board yet :(
Unfortunately, I didn't get the board yet. do you have another training in addition to the 25.3?
Wake up from stand by from a tamper pin.
Hi all,It is possible to wake up a STM32F3 series MCU, in stand by mode, from a tamper pin?
UART Transmission and Reception between STM32 Nucleo-64 and Raspberry Pi 4
Hello,I am new to the ST developers community. I have an large file (4 MB) that I need to divide it and transfer data chunks serially from Raspberry Pi to STM32 Nucleo-64 board including the STM32L073RZ MCU with a certain delay to allow the STM32 Nuc...
Stm32 Nucleo L476RG
Hi,I'm using a Nucleo L476RG as a master and I want to use it in SPI mode 1, which means the data is transferred in rising edge of the SCLK and data is sampled in falling edge (based on ST documents). Is this the correct configuration for the SPI mod...
Resolved! STM32F410R8 SPI DMA not reading
I've configured the SPI to work with DMA. The microcontroller is sending but is not reading. I have checked the configuration and I cannot see the problem. Can you see something strange in my code.I've tested this code in an STM32F429-DISCO board and...
STM32H7 FMC or memory mapped IO timer triggered DMA/BDMA write/read access
Hello everyone,i am working on the STM32H743 evalboard. Setup is fine and the external SRAM3 can be read/written correctly bysome memory mapped IO access. I want now to implement some timer triggered(event or IT) read and write FMC or memory mapped I...
