Hi, I'm currently working on adding external memory to a Nucleo STM32F446RE board through 4bit SDIO using the WaveShare microSD BB: https://www.waveshare.com/wiki/Micro_SD_Storage_Board.I created my project with STM32CubeMX configuring SDIO and FatFS...
Hi,at the moment i'm stucked at the configuration of the MTL (STM32H743).For example:I'm looking at RM0433 rev7 p. 2934.RQS (Receive Queue Size) has only 3Bits [22:20] and 'this field indicates the size of the allocated Receive queues in blocks of 25...
Is it possible to do a DFU/SFU via USB CDC, how? On the UM2262 Applicate Note it mentioned on page 39 that local firmware download can be done through a UART Virtual COM port. I assume UART Virtual COM port is not the same as USB CDC. Appreciate your...
I tried to run it but LD7 which is below USB fault lights upAnd i think there is too much current taken from the USB which lights LD7 redI reduced it to 15 GPIO output pins and its fine nowWorks goodBut my project requires the use of around 70 pins
How much memory should be available in the device flash to do the firmware install? If my application takes up >80% of my device's flash is it even possible to do a firmware update since most of the flash is already used up.Appreciate your support.
Hi,I'm trying to develop a module where information from a buffer is read by DMA and sent through UART, but the information is put in the buffer without a constant rate and it might happen that the buffer is empty, if that happened, I understand that...
Hello,I am using STM32F417 to control a sounder among many other functions. In the firmware, the DAC is controlling the sounder which works fine when tested alone. However, the moment the FreeRTOS is enabled, the DAC stops working. What I am suspecti...
So dividing the sampled data and trying ti do each segment fft just like i did in matlab but the problem is the first segment fft is working next to that fft giving strange values. But if the second set/segment is done fft first it gives the right an...
I'm using STM32H743ZIT6 for an audio speaker, and while I was trying to set SAI1 for a DAC I2S connection and SAI4 for a PDM digital mics, CubeMX keeps giving me this error for PDM setting.SettingsSAI1 A&B is set for Asynchronous I2SSAI4 A is set for...
Hi there,I need an IAP bootloader via CAN interface with G431 MCU. Before I had developed for F446 and no problem, and it works properly, no problem, but not for G4.The bootloader code has not called the application although set the stack pointer wit...
