I'm using STM32L4S5 to develop an IAP application following the example provided on STM32L4CubeV1.11.0 under STM32L476G-EVAL directory.Following the code bellow, before jumping to the Application region, we have to check if the content of the first a...
We are creating a composite USB HID / Audio device using STM32F072 part and would like to sub licence an ST PID to use with this device if possible.Can you send me some details on how this arrangement would work?Estimated volumes are 10k pieces per y...
I am using stm32f746g discovery board for my application. Currently the memory allocation is done on SRAM. I would like to use SDRAM for all dynamic memory allocation. I tried changing heap address to sdram address in linker script, but this gives ha...
Hi,I am using a DAC which takes data in 24 bit format, 8 control bits and 16 data. I currently have two seperate large 8 bit and 16 bit arrays.I want to change between modes on the fly before each transfer using SPI_DATASIZE_8BIT / 16BIT, but it stay...
Hi everyone,I'm having troubles with the internal ADC (STM32F072CBTX): a significant offset is present in the values provided by the converter. I performed a set of test measurments on the ADC: the results are shown in Table1.jpg.Where:Vmis is the vo...
Hi,I am using Keil V5.26.2.0. Although I have installed DFP for my particular MCU, from where I may get bsp for my board. Please be gentle guys, I am pretty new to the world of MCUs.Cheers and a happy dayTahir
ST community,The issue I’m having is getting DAC2 to work, DAC1 works great. I’m using TrueStudio no HAL, everything setup manually. I’m receiving data from PC to mic USART then adjusting Vout on DAC1 and hopefully DAC2. The main question is I can’t ...
