Hi,I found a tutorial for using a BME280 sensor with I2C in HAL (https://controllerstech.com/bme280-with-stm32/).However, I need to use LL for it to fit into the rest of the program. The main part I'm having an issue with is below as I can't find a c...
Hi!The following was tested with Nucleo-H7ZI.I have generated a project with basic defenition of freeRTOS and LWIP.Once an ehternet cable is connected to the board the program collapses and goes to hardfault.after comparing the LWIP code from current...
I'm trying to use an STM32G491 in a voice recognition application. This is a single microphone, mono voice capture application. I'm using an NUGLEOG491RE and an MP34DT05-A microphone (1/4 STEVAL-MIC001V1) for testing. I need to convert the PDM stream...
I have project that I'm designing around an STM32F411 that 99%+ of the time will not have a USB device attached. I'd like to run at the top clock frequency of 100MHz. I see that I can not do that and use the USB device as it needs to run at 48MHz. I'...
I am working on STM32F107 to read MP34DT05-A mems mic on I2S. I have tried any configuration setting with `pdm2pcm.c` and i2s.c but nothing shows the expected result.The expected result is positive int value. This is what i did so far:i2s3 (SPI3) set...
I use a timer to wait for the next interrupt from the keyboard . The timeout is 30 Secs. The issue here is the HAL_TIM_Period_Elapsedcallback is getting called frequently , but I have set the timeout to be 30 Secs. Can anyone help me fix this issue ...
Hi there,I am trying to explore IoT options with the B-L462E-CELL1 discovery kit (STM32L462RE mcu). I was hoping for a software environment that I could use as a springboard to start working with this device, but I have not been able to find one.I ha...
In this loop the mqtt client is created, connected and as long as the mqtt server/broker is up, the client continues processing messages. But when the remote mqtt server/broker is manually shut down, and after the timeout expires, nxd_mqtt_client_c...
I followed the linked tutorial, implementing STOP2 with a tickless idle, toggling a GPIO pin and calling osDelay in the main task repeatedly. The processor remains awake for 15ms with a core clock of 64MHz, and increasing the core clock somehow incre...
Hello, I am working on a project for the stm32g0b1 mcu that does not interface with type C ports. It will only be connecting to usb 2.0 devices. Since I don't need the power delivery negotiations for the type c ports, I have been combining the exampl...
