hi fellows, i'm developing the SD card application for STM32f429 discovery boards. i have the FATFS software with myself. my point i want to develop my own driver for SD card i don't want use HAL driver . i developed the initialization code for SD c...
I wish to use MDMA to push a two dimensional FFT complex FIFO array in the AXI Memory, using MDMA.I have an array of 256 * 128 complex floating point numbers, and wish to copy the first 127 columns over the last 127 columns to make room for the next ...
Where do you connect JTAG (e.g. TMS, TCK, TDO, TDI, NRESET) to the STM32F091RC? I can't find this anywhere in the datasheet (r4-1/17), is this supported?
Hello everybody. I am trying to develop a project in which i am continuously reading a serial protocol like a slave. So i would like to be in sleep mode and wake up when the message arrive. But i dont know if it possible to wake up the MCU when my UA...
I'm using RFID EM4095 with my STM32 microprocessor, i'm trying to read the RFID card but i always get bad synchSTM32 Clocks -> 16MHZ ,32KHZDMOD_OUT ->PB3, rdyclk -> PA15I'm using 2 interrupts for DMOUD_OUT, RDY_CLK signalAlgorithm1.wait for falling e...
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...
