Hi everyone,I’m encountering problems with SPI communication with the board NUCLEO-H753ZI and the EVAL-AD5764 from Analog Devices, as this is my first time working with it, and I’m unsure if I’ve configured it correctly.I’ve consulted a forum for Ana...

Hi everyone,I’m currently working on an I2C communication setup using the Nucleo-H753ZI DK but the cubeMx document is for the STM32H743BIT (the MCU for my custom board) and aiming to run it in Fast Mode (400 kHz). However, when configuring the I2C cl...

Hi,I’m encountering an issue with linker file generation in STM32CubeMX for the STM32H56VGTX MCU. When I generate the code using CubeMX, it produces linker files configured for the STM32H563xx family, which has 2048 kBytes of Flash memory. However, t...

Good morning everyone!I'm working on a project involving FreeRTOS, lwip, and Ethernet with the ST32H563VGT6 MCU on a custom PCB.I'm attaching the hardware schematics, which we've taken from ST's schematics of the NUCLEO-H563ZI board. I'm including a...

Hi! I'm using a custom board with STM32H563 and recently, I've set up the Ethernet connection, but I'm encountering issues with GPDMA interrupts for controlling a PWM signal for one wire communication to control addressable LEDs. In my project, I'm u...

Hi Andrew,I see that could be a problem but I must achieve 400kHz in the I2C. Regarding the maximum I2C current limits are 25 mA for the PCA. What would you recommend?

Hi Padawan,I am using an oscilloscope to measure the frequency, and the resistor reduction was made to achieve the correct waveform for the CLK signal.For the pull-up, I am using 5V. Attached are some measurements I have taken with different resistor...

Hi Padawan, thanks for your reply!It seems that the 3.3kΩ resistor resolved the CLK integrity issue. However, I’ve encountered a new problem regarding the CLK speed of the I2C. I’m aiming for a 400 kHz CLK speed, but currently, I’m getting a 378 kHz ...

Thanks a lot for your response!Regarding the pull-up, I am using the MCU’s internal pull-up.As for the logic analyzer, I’m using a Saleae Logic 8 with a 10 MS/s sampling rate.Also, just to add, I’m working with the PCA555, which supports 400 kHz.

Hi,I’ve found how to replicate the issue. If I generate the linker file directly from your .ioc file, everything works fine. However, when I switch the Toolchain/IDE to Makefile, the linker file generation is incorrect, producing a generic one.What ...
