Hallo,I have a board with stm32u5. This board sends mqtt messages to a broker using a cellular modem.As os, I'm using AZURE RTOS. I'm wondering if it's better to use lwip, netxduo or stm32_cellular as a substratum. Where can I find examples of netxdu...
I an using stm32f030c8tx need to generate a pulse with a desired frequency, which can be adjusted through three different modes. The modes are as follows:Frequency remains the same.Frequency is divided by 2.Frequency is multiplied by 2.The mode is s...
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...
