Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
So even newer STM32s still have both of UARTs and USARTs.My question is about how they are going to be supported in Cube libraries.Am dealing with H7x3 recently, and noticed that the UART example actually is for USART - as the serial connector on the...
Hi everyone,I'm trying to log data from different sensor into a USB flash drive with a 500Hz sampling frequency.I set up a timer to define the sampling frequency for data logging and everything seems to work fine.The problems comes when i try to wri...
I am trying to write a USB driver. I set-up EndPoint 0 when I get a RESET from the host. This writes both the EndPoint Register as well as the Buffer Descriptor Table.I can see that the EndPoint 0 register is written correctly, but the Buffer Descrip...
The USB device I need is working with a set of newer libraries (mxCube). All my application ported code is written with older libraries so the permutations are:A. App with older libraries combined with USB running on new libraries (lazy way, short cu...
The processor is a STM32F107RB. We dont have the possiblilty to update it via jtag.
Hi,'Audio_playback_and_record default uses INPUT_DEVICE_DIGITAL_MIC as Audio input.I'd like to replace the Audio input by SAI's I2S with an external mic slave device.I add INPUT_DEVICE_AUDIO_I2S as new Audio output. And run the flow as INPUT_DEVICE_A...
I am using STM32F030C6 micro controller. In my firmware, I need to keep a variable in RAM location 0x2000000. This variable is accessed by both boot loader and firmware. So a reset should not affect its value. So how can we declare such a variable ? ...
Here below image of the MCU on my two nucleo boards. I tried to program the MCUs using SMT32CubeProgrammer and USB-TTL converter connected to USART1 via pin PA9 and PA10, BOOT pin tied to 3V3. I press the reset button, then try to connect F070 MCU bu...
Section 2.1.2 of AN4938 states: If a USB interface is used (USB OTG_HS/OTG_FS), the associated GPIOspowered by VDD33USB operate between VDD33USB_MIN and VDD33USB_MAX(seeFigure 2).VDD33USB supplies both USB OTG_HS and USB OTG_FS transceivers. If onlyo...
