I’m a newbie when it comes to flashing microprocessors. I am wondering if anyone can deduce what I may be doing wrong given the following set of facts.1. The device I was trying to repair had the symptom of halting after the progress bar instead of b...
Posted on April 23, 2018 at 18:00Hello, I'm using STM32L071RBT6 MCU, encounter a strange issue. when MCU power on, using ADC channel 0 to monitor external battery voltage, the result is OK. but once system waked up from STOP mode, ADC converter be...
HI, I configured boot pins STM32G030 to enter bootloader at startup of system, but now how do I check if the chip is actually in bootlaoder mode?After setting boot bits, I know that the main application code on flash memory is not loaded at start up ...
Hello, I'm using the STM32L072 MCU as part of the Murata CMWX1ZZABZ-078 module in my application. I want to configure the Low-Power Timer (LPTIM) to generate a wake-up event when the MCU is in Stop mode. Could someone provide guidance on how to confi...
Hi All, We have recently spun a PCB with a BGA packaged STM32 processor. Unfortunately I am having real problems with the board bring-up. The 3V3 rail is getting clamped to around 1.9V when I have a 100mA current limit on my PSU. A thermal camera has...
Hi :I want to use audio class with AZRTOS, but even I select audio, I still can't find audio in middleware.
Hello everyone! I'm close to validating all my schematics for a PCB project, and I wanted to be sure at 100% that a section is correct.I'm talink about the USB-C section, that connects directly to the STM32H7 microcontroller. It will be used to acces...

I'd like to use both of the Synopsis USB controllers on the STM32H743VIT6, one as device, one as host, but to do that I understand that the other USB controller is accessed through the USB HS device, which is disabled because of the use of LTDC.Curre...
Hello!So after few frustrating hours (as usually with ST), i reached the state when i found that CRC peripheral on STM32G4 (at least) DOES NOT SUPPORT DMA. Like are you kidding me? Is it for real? First of all i could not find a DMA request for CRC. ...
