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...
Hi all,I'm using the MDMA to communicate with an external flash over QUADSPI.I have an implementation which works great without FreeRTOS, but when I implement it using FreeRTOS I get Transfer Error Address. I have verified that the RAM address exists...
USBD_FS_InterfaceStrDescriptor() is not called.I fix it by changing iInterface by 5. To match this define:#define USBD_IDX_INTERFACE_STR 0x05U /* Data class interface descriptor */ 0x09, ...
While output data from DMA to SPI it should be able to use two buffers. One for the current transfer, one to write data.But how do I switch between the buffers?#define BUFFER_SIZE 10 uint8_t txBuffer[BUFFER_SIZE + BUFFER_SIZE]; HAL_SPI_Transmit_DMA(&...
