Back in 2018 this question was posed and I have more information.The answer to this question lays at the bottom of UM1734 where a static allocation code snippet is given.There are two problems with this code snippet that will come back and bite the u...
I have been working with the STM32F427 using CubeMX and TrueStudio for a couple of years now, and getting freertos thread awareness into the debugger has been a constant challenge. Sometimes it works, sometimes it doesn't ...My current situation, usi...
Hi, I am using the STEVAL-STWINKT1 board with STM32L4R9 MCU. I want the USB work as Mass Storage linked to 4GB SD Card, connected by SDMMC 4 bits peripheral. SD Card is formated in FAT mode. Dare are read throught FAT_FS Middleware. It is currently w...
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 . Why does the amplitude have halved by using arm_rfft_q15 ? uint16_t i; fl...
Hi Guys,I am implementing Event flag group inter task communication in RTOS where in one task device waiting for even and and setting the event in Uart ISR and code entered to vPortRaiseBASEPRI() and never come out.Device is nucleo 64 of STM32L476 a...
For whatever reason, I'm getting byte alignment problems with queues. I have a 32 byte queue, and the last two bytes are now garbage (they weren't before). No system settings have been changed, and I'm using all the defaults. If I expand the size ...
Right now, i have generated a hex file using objcopy, added a crc etc to it.Now, is there any way to add this hex information back to the original elf file? It would be nice to have it all packaged in one file back again.
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, ...
