Hi,Recently, we desighed a test board with STM32F103RB for UART communication with a wireless chip, and we found that the HAL_UART_ErrorCallback is triggered occasionally (the periods of errors vary betweent tens of minutes to hundreds of minutes), t...

Hi,I started a post a week ago (https://community.st.com/t5/stm32cubemx-mcus/software-reset-fails-in-eth-configuration-for-lwip-with-f407/td-p/659641) that has been viewed over 60 times without any reply, for finding a solution for this issue, I woul...

Hi,Run from CubeIDE had not seen any issues until yesterday, but since then I can't run from CubeIDE, and don't know why.Download in CubeProgrammer is OK. I found if I do a mass erase on full chip in CubeProgrammer, then I can run once in CubeIDE. Th...

Hi,Recently, I got a copy of code for LWIP working with F407ZG in Keil project, I successfully ported it into CubeIDE with full functionality of CubeMX except for ETH selection (i.e. ported the code into a normal CubeIDE project with .ioc file withou...

I've been confused for days and am unable to make the ADC work on F103RC and have to seek for help.The test consists of ADC1 with 6 channels, an UART for printf and an I/O port that drives an LED. The ADC configuration: The test code: /* USER CODE BE...

Thank you so much! The posts you recommended are quite useful, they are similar to my case, now I know this error is caused by the partial erase code on flash in the project. My solution of this issue is simply to change the reset behavior from conne...

Hi,I encounter the same issue and wrote a post for it:https://community.st.com/t5/stm32cubemx-mcus/software-reset-fails-in-eth-configuration-for-lwip-with-f407/m-p/659641#M27794In my case, I am pretty sure that the GPIOs configuration are correct for...

>Then disable any end of conversion detectionI think this could only be done by modifying adc.c as I didn't find the way in CubeMX

I tested Continuous Conversion Mode + DMA Circular mode, and expected that the ADC perform conversion again and again so that whenever I need I could read the result (e.g. every application loop), but it does not print out any ADC result for me, prob...

>Not the best? why? because it's a test? or because it's more difficult to implement?Sorry, I meant my implementation of the one-second timer is not the best.>You need either (as said by @raptorhal2 ) to disable the Continuous Conversion Mode or enab...
