Hi, I am currently working on a project using the STM32H747i-DK development kit. Where I am focusing on interfacing a camera ov7670 module module with the board and displaying the video feed on the attached display. Can anyone provide any sample code...
Hi, I am looking to understand how best to size the power supply for STM32F413ZHT6What is the maximum current that this processor could draw on the 3V3 rail? Cheers,
Hello, my problem is as follows:I am working with an STM32G484QET6 uC. I have configured two timers with two output channels as Output Compare Toggle Mode. So that I get two independent quadrature signals.I now want to synchronise these two quadratur...
I am working with an STM32F3, a ChipWhisperer and the SimpleSerial library right now and trying to follow instructions executed. While doing so, I noticed that the number of CPU cycles does not seem to match what I expected from the ARM Cortex-M4 ins...
Hello,I recently created a custom board using the STM32F746. I'm encountering an issue with the QSPI interface. The problem arose when I replaced the external flash from the MT25QL128ABA model to the IS25LP128F model. I have checked the data sheet an...
recently i been making a device that fulfill the following requirement using stm32f103c8:1. Use the STM32F103C8T6 (Blue Pill) development board.2. Connect to an RGB LED using suitable I/O pins. An RGB LED is a combination of 3 LEDs (red, green,and bl...
Hi,I would like to change at runtime some user-defined variables stored in Flash (so they remain on the system after power off). I have defined them as const and some are just 16 bits vars and others are more complex large structures. What is the bes...
Hello, I have a signal that is coming to a GPIO and the period of the signal might slightly change and I need to realign a timer each time the GPIO is on rising edge.I try to use the TIMER1 with Slave mode reset and use ETR1 as trigger source. but it...
I have a custom board that I am getting ready to program that is using the STM32U575. I am a little confused about the clock configuration. My board has an external 32768 crystal. I am not sure I have the MX program clock configuration correct. I wan...
Hi,I've tried finding a document that would describe what do the different error codes mean for the CAN FD module.Does anyone have a link or an idea where to search from?My CAN FD peripheral ends up in error status 516 at some point and I can't find ...
