I was trying to use arm_rfft_q15 .In the CMSIS documentation for arm_rfft_q15, it says the output format is Q7.9 and 6 bits should be upscaled when the input RFFT size is 128 . What is meant by this? Do I have to get the float values by dividing the...
I config ADC with DMA and TIM2. By TIM2 overflow starts ADC process for ADC1 ADC2 and ADC3 simultaneously. DMA collect ADC data and store to RAM. In debug i see that DMA for ADC1 transfer the same ADC data several times.For example:ADC1: 32, 32, 32, ...
I'm using an STM32F722 to implement a USB Host (FS) for HID class so that I can connect a mouse to my custom board. To rule out any soldering problems, I bridged both ESD and overcurrent protection.Over the past couple of days, I've been testing USB...
Hi, I'm using an STM32F429 zi board. I'm saving data in the SDRAM and then I'm reading it and sending it to TeraTerm with the micro USB connection.But there is some problem with the micro USB connection because TeraTerm detect the board but it doesn'...
Is there a bug in the SVD file for the STM32G431? It appears to list ADC12_Common->CCR as being at address 0x50000208 when it supposed to be at 0x50000308
Hello,I want to implement USB composite class of MSC + CustomHID on STM32LRR5ZI development board. I created a library file for the same by combining functionalities of both the class. But PC is unable to recognize the USB device connected to it. Can...
Hi everyone,I'm following the LWIP_IAP application in STM32756G_EVAL 's Repository. The bootloader work fine, but I don't know how to config the application firmware to boot from a specify address flash.Is this the right way to config flash memory o...
Hi, I'm looking to connect a STM32H7 board to iot core, simple stuff: publish and subscribe to topics.I found x-cube-aws but i don't know how it works (I read the getting started guide but no success).In the aws documentation for freertos i didn't fo...
