Hi, Im planning on using STM32H747BGT6 in LDO mode only and no USB interfaces will be used. What should I do with SMPS pins (VSSSMPS, VLXSMPS, VDDSMPS, VFBSMPS) and USB supply pins (VDD50_USB and VDD33_USB)? The datasheet nor the application note don...
Hi All,I'm new to using the STM32 and honestly had great grief trying to connect to the chip.I'm using STlink V3 and designed my own PCB.Trying to flash a F/W to the PCB. I ordered the PCB from JLCPCB.I keep getting unable to get core ID as a message...
The datasheet for STM32U585 and 575 list there are two SAI on the chip. In CubeMX I can only see SAI1 (A and B sub-blocks)Datasheet CubeMX pin menu
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 am attempting to display to an ILI9881C based panel. After successfully initialising and testing the panel using DSI only, I am working on DSI Video mode to pull data from a frame buffer via LTDC.I have the DSI configured as follows static void MX...
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, 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...
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...
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...
