As shown above picture, I got my STM32F405 configured as open drain to drive the led that is connected.Also, the same pin connected to via hex inverted (74HCS04D) to invert it and connected to OR gate. But when the GPIO pin in reset (low) state volta...
I wrote a test that uses the DMA2D to transfer 64kB of data from AXI SRAM to an external SDRAM. I set the source data to be all 0xFF and started the DMA. Using the Memory viewer in STM32CubeIDE I see that the SDRAM is getting filled, but there are ...
Hello Everyone i am using stm32G031J6 Microcontroller. I want to generate a PWM signal from Timer 1 working as slave in gated mode, that has a pulse width = 10us and pulse period = 44us In this microcontroller i am using Timer 3 as a Master which ha...
Hi, I'm trying to get the ethernet interface to work on an STM32H745. After fixing various hardware problems, now I don't just have software problems.I created a simple project with CubeMX, basically I did these things:- Enabled ethrmnet interfaces- ...
I was trying to build the sample project in GitHub [https://github.com/STMicroelectronics/STM32CubeL4/tree/master/Projects/NUCLEO-L476RG/Examples_LL/I2C/I2C_TwoBoards_MasterTx_SlaveRx] for NUCLEO-L476RG board.I have tried the below methods to import ...
Hi, I am using a stm32h753 controller for my project, in which I need to store public key which could be updated during runtime. Is there any way I could store it inside the controller securely? Also do the stm32h753's flash has OTP? I could not find...
HeyI am working with NUCLEO-H723ZG. I try to sample signal of sine wave at 25KHz to buffefr with size of 100.I want to get something Like Interrupt when the buffer is full.I look for some examples in the internet about the configuration of the IOC bu...
Hi all,Just read RM0440, the section is USART Baudrate generator. There is the formula contatins input never met in all other document. (found 3 times, all of them are on the screenshot). What happened with ST technical writers? I never met cases lik...
We are using a Any bus module M40 in our project which is based on STM32F769BI.The FMC interface is connected to the Any-bus module as per the attached schematics. This interface works for 8-bit mode of anybus. However for 16-bit mode it is not worki...
Hi,I would like to use this device: STM32H753VIT6 to communicate withan SD-card in SDR104 mode.As I understand it would require an I/O voltage on the card side of 1.8V. This is where I become insecure if the given device can generate this voltage int...
