Resolved! i would like to know how linker commands can be used in source file to push the multiple structure defines into a part of code memory. can some body share with examples
steps i tried.step 1: created a section in linker file ".parambuf"step2: in source file declared a structuretypedef struct{ param_t param[256]; \} t_param_block_t;step 3: in header files using attributes commands to push into parambuf section.extern ...
Resolved! STM32F7 + QSPI (QUADSPI): Sporadic failure with memory-mapped flash memory. Disabling timeout does not help.
Hi everyone,We have an issue when using QUADSPI (memory-mapped) on a STM32F7 microcontroller. The controller sporadically runs into a watchdog reset. Investigation showed that the crash always occurs during a LDM instruction from the memory-mapped fl...
Resolved! What STM32 Microcontroller will fit me
I am trying to make the transition from Arduino/Atmel micro controllers to something that can support true threading/multitasking in the 32bit ARM processor category. I am making a robot where I need to control 7+ 12v motors, 24 servos, 100+LEDS, spe...
Problem Porting TLS CLient from F207 to H743
I managed to get a simple TLS client working on the NUCLEO-F207ZG. I cannot get the program to run on the NUCLEO-H743ZI2. On Wireshark I see several DHCP DISCOVER messages go out; followed by an OFFER message coming back. My code never responds with ...
Do SPI pins ever float?
When I used buffers between CPU and SPI peripherals I got problems. There were no Pull-ups.Bare GPIO pins with pull ups work. So do SPI pins float between transfers?CPU happens to be STM32H750/STM32F746 if it matters.
Which STM32 part has the fastest ADC sampling. Is there any MCU with 1+ GSPS. Is there any way for me to use an stm32 to sample 4 inputs at 50MHz analog BW each?
I am trying to sample 4 inputs at 50MHz analog BW. Which STM32 MCU can support this? Does it have a fast interface to stream that data out?
Resolved! Why is my SPI slave only sending one byte?
I am trying to read the position of an absolute rotary encoder (AMT22B-V). I have it connected to a Nucleo G474RE board. In the main.h file of the STM32CubeIDE project, I have the following declaration:#define BUFFERSIZE (COUNTOF(aTxBuffer...
STM32H7 HAL ADC with DMA Init ends in Error_Handler (CubeMX)
Hello, I am using an STM32H743VIH6 in a custom board. The MCU is running with 3,3V. I generated code for the MCU with CubeMX and configured the clock, ADC1 and the DMA. Attached the generated main.c file. Inside the fuction " MX_ADC1_Init" the Error_...
SPI1 on pins PA5, PA6, PA7 does not transmit and receive data when used in DMA enabled mode for NUCLEO-F303RE.
I am trying to get the SPI communication with DMA enabled mode for STM32F303 controller using nucleo board NUCLEO-F303RE. For this, I am using one board as SPI master and other as SPI slave. Pin connections on hardware (as per nucleo board):Pin 8 on...
