Hi everyone,I’m currently trying to bring up an external RAM (HyperRAM over the HyperBus protocol) on the STM32L4R9I-EVAL board. While going through the documentation, I’m finding that information related to OCTOSPI and HyperBus on this family is qui...
Hello, we have device with very old TFT display which is dying. New one is unable to obtain. It has similar interface as DCMI: vsync, hsync, pixclk, D0-D8.I have connected these clock/data lines to DCMI port, but interrupts was not triggered.Here are...
Hello,I am working on a hobby project with https://www.st.com/en/microcontrollers-microprocessors/stm32f767zi.html.I have my own build and development environment based on arm-gcc-none-eabi and CMake and all HAL Drivers and Libraries from STM.The boa...
As the subject says. I am not able to connect and re-program or debug my STM32C011 ICs after I set up SWCLK and SWDATA as ADC on my firmware.NRST pin is connected and it still doen't workI know this is expected behaviour, but I should be able to re-p...
Hello,Trying to do precise GPIO pulses with assembly code - on any STM Nucleo board - shows jitter and fluctuating frequency. I was told by a super user to do it via PWMI would like to add some comment that may be interesting for others :- trying to ...
Hello,I'm using the STM32H723 (at 550MHz) to generate pulses on a GPIO output at a certain frequency (around 4KHz)I'm generating the pulses with assembly code. I've stopped systick and interrupts. However, looking at the signal with a scope, I'm disc...
Hello, I want to add a SDRAM chip to my board. Processing the images with internal RAM is insuficient. Reading the manual for FMC part I'm not sure how the bandwidth is working. If I have a chip with 8/16/32 bit, is pretty clear: one chip and that's ...
Hello ST community,I have some troubles with dummy cycles using Quad-SPI interface in DDR mode on STM32H743 and STM32F746.I am trying to read data from IS25LP080D QSPI flash with FAST READ QUAD IO DTR MODE OPERATION (0xED command). It is 1-4-4 mode.I...
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
Greetings!I have the following system:STM32U073CCVBAT pin is connected to a super-cap, and it's voltage was measured to be above the required minimum.During system reset (NRST) it behaves according to my expectations, the RCC_BDCR remains unchanged, ...
