Hello,I would like to know whether I understood the application note about the Vcap pins correctly. If there are 3 Vcap pins on the package, then 2 capacitors should be placed and one has to be connected to another. I'm not sure about this connection...
Hello guys,In some of the products we developed with STM32F429, we received the write-protected error I mentioned in the image. I know how to turn off write protection, but I can't figure out how it activates independently. However, there are also ma...
Heyho,first of all, I know this is a Microchip product, but their forum is rather dead.And I have seen some people here using the KSZ8863RLL. So please bear with me... I'm currently working on a big and complex PCB including the "dual PHY" KSZ8863RLL...
On a STM32H745ZI-Q - Board I want to create periodical 4-byte SPI transfers triggered by a timer. So far I got this working the following way:TIM triggers DMADMA initiates the SPI transfer.However, the SPI transfer timing (CS low) has a high jitter ...
HI all, I am building a system to control my battery charger.When I power up the system from the DC power supply it work perfectly.But when I power up this with AC power supply it gives below error. What can be the possible error?
Are there experiences regarding the record of a signal in look to the 64-bit platform linux?Do I need a 32 bit-emulator or something like this?
Hello Everyone!I'm facing a problem with all the examples on this package FP-AI-Vision and my LCD only displays noises. I have the board STM32H747I-Disco model MB1248-H747I-D03 and the display MB1166-A09. I realized that in this package doesn't has t...
Hello, I've written a software to use the FDCAN (classic frame 500kbit/s - PB8/PB9 pins) on Nucleo-H7ZI43 (FW_H7 V1.7.0 and stlink V3J13M4 FW)All works fine, I'm able to transmit and to receive message with different ID and DLC by mean Innomaker CAN...
Hi folks, i have an STM32F407 discovery board. when i measure the voltage across the gpio pins it becomes write protected. after i dumped many codes but no use. i had attached the screenshot with the error code that it's display. i tried to put jum...
Hi,I got the VCNL4040 Proximity sensor breakout board. I tried this board with Arduino Uno example solution and works very well.Now, I am trying to read this sensor with an STM32L0 series MCU. I see I am able to write to the sensor by turning ON and ...
