I am trying to implement a USB 2.0 FS device on STM32H5 without using HAL or anything else. There might be a need to send back a request error (STALL) during enumeration:- and it is OK to return STALL to an IN transaction, so I can set STTX to STALL ...
Hey there,another question. I can successful output 8 DMX universes received via Artnet using DMA (Mem->Periph). At the same time I want the possibility to receive upto 8 different DMX signals connected to the MCU. Therefore I hooked up the receive l...
Hi All, I am looking to use the STM32H745 dual-core chip in my next design. I currently use a CH9121 device that handles the transparent ethernet to UART bridge for me and looking to incorporate this functionality into the STM32H745 on the M4 process...
Dear ST professionals,Continuing the previous problem reported at https://community.st.com/t5/stm32-mcus-products/mb1641-nucleo-stm32wb15cc-slowness-between-ble-and-uart/td-p/603759, I have problems when use LPUart to wake up from STOP Mode. I tried ...
I want to use the IWDG watchdog with the maximum possible time delay of approx. 30 seconds. As the device cannot be switched off, It has to go into standby mode (HAL_PWR_EnterSTANDBYMode) instead. The issue here is, that the watchdog would wake it u...
It's my understanding that it is a bad idea to mix lead-free and leaded solder, and that it can cause cracks.I'm using a TFBGA100 package on an STM32H7 and have some long-term reliability requirements. In order to avoid tin-whiskers, I was considerin...
In my project it can happen, that the LSE gets blocked due to a CSS failure detection after repowering. I found this good article on the ST community which maches alomost with my case: https://community.st.com/t5/stm32-mcus-products/lse-fault-recover...
I read RCC RSR to determine the cause of reset. It is not clear to me the purpose of RMVF bit. I guess it resets the other flags but why would I want that ? I wonder if I am missing something.
Posted on March 23, 2017 at 12:06i search in google and i can't find any adc external trigger example code i found timer trigger only.i want adc start conversion when external pulse found.i want any example code
What is the maximum clock source frequency can I use as an external clock for timer?I have a 20MHz source and PLL frequency made out of this source. The purpose - generate lower frequency pulses that synchronous to that 20MHz clock with controlled de...
