STM32 MCUs Products

Enable a UART loopback connection on the development board STM32L476, to send "hello world" from UART 1 peripheral to UART 2 peripheral of the same microcontroller. I can not configure 2nd UART in Async mode. Can anyone guide me on it?

STM32F417___WRITING DATA THROUGH I2C3 CAUSE EXTI9_5_IRQHandler TRIGGER

1) I have configured PG8 gpio as external interrupt mode.2) When i am writing data using I2C3 , EXTI9_5_IRQ Handler is getting trigger,but their is no activity in PG8 pin. What is the reason for this problem.I2C3 GPIOs. PC9 -> SDA PA8 -> SCL

Capturing stereo audio on STM32F4 with internall ADC

What I want to do is capture audio using ADC0 and ADC1 with DMA. Until now I have not been able to find a decent solution on capturing 2 ADC inputs simultaneously using DMA.Is this even possible?

How to solve file system corruption on my NAND flash after power failure

Embedded File System(EFS), Fat32, through user defined diskio is used on a NAND flash, MT29F1G08AB, in my project. After a sudden power failure during a file operation on this EFS, I realized the EFS turned to be corrupted and the file system cannot ...

How to write a parser for UART 'control packets'?

Hi allI've just jumped on the STM32 bandwagon so apologies if this post isn't in the right place. Just let me know and I'll go annoy the right people :)I've done some work with the ATMega AVR range, both via Arduino and native so I'm not a complete n...

Best way to handle multiple definition errors (project structure or variable declaration)?

Hello!I have a project I setup that I'm getting multiple definition issues with and I'm not 100% sure if it's because of they way I structured it or if it's because of the way I declared it.Variable Declaration (since this will be easier to read and ...
