Hello, I'm using Nucleo H723ZG.In my project, i need to detect a rising edge to trigger a callback. What i have done is that i setup a GPIO as external interrupt, and i verified the code by manually connecting and releasing from 3v3 pin. The actual s...
Hi,I read this pagehttps://community.st.com/t5/stm32-mcus/understanding-the-bootloader-issue-with-the-go-command-on-the/ta-p/750839but i still have problem to perform the speical reset command of the STM32H5 FDCAN bootloader.I sent 'Special Command' ...
Split from this thread. Thank you for your previous responses and guidance. We are now planning to move to the STM32H750XBH6 (BGA package) with a 32-bit SDRAM (IS42S32400J-6TLSDRAM ) interface in our custom board design.Our project uses a 12.1-inch d...
Hello stm community. I am working on a project involving STM32H7 series MCU with Raw LCD panel of 24 bits. Since the display has no IC i am using the internal LTDC component to drive the lcd. So i have some questions can i drive the lcd backlight wit...
What does DMA Request synchronization do? In the case of SPI_Rx does it trigger SPI reception when TIM12 updates (overflow) if i set synchronization signal to be TIM12 TRGO
I'm bringing up a design based off the STM32H573 and I believe I'm having a number of issues that are probably sharing a common thread with bad hardware. I don't usually screw those things up, but I guess I got unlucky this time.1) PC1 when configure...
I like to use SPI in continous DMA mode together with a SPI-slave that uses the falling-edge of the spi clock (AS5048A: https://ams-osram.com/products/sensor-solutions/position-sensors/ams-as5048a-high-resolution-position-sensor). So, I have to use C...
Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA...
I've searched and not found anything describing this behaviour (on the internet or this forum, which I've found to be an incredible resource so far - thank you).I have a configuration where I go into STOP, exit out of STOP via EXTI, start TIM1, allow...
Hello, I am fighting about a week to enable USB-PD comms on my STM32G0B1 MCU and even chat GPT literally told me - he don't have a solution ( shock, a?) One last try before I quit, is to try 1.5.0 package version but I can see in cube MX only 1.6.0 ...
