Build ErrorError[Li006]: duplicate definitions for "HAL_SPI_TxCpltCallback";void HAL_SPI_TxCpltCallback(SPI_HandleTypeDef *hspi) { HAL_GPIO_WritePin(SPIx_NSS_Port, SPIx_NSS_Pin, GPIO_PIN_SET); }I use the same in both files ?any way ? please help

I have a working code for SPI with DMA support added. Now I want to improve the speed of operation.I am using an STM32F427 controller.#define SPIx_Mode SPI_MODE_MASTER #define SPIx_Direction SPI_DIRECTION_1LINE #define SPIx_Dat...

I was debugging some code in STM32F4 controller. I build and flash some code related to DMA, During the debugging process the code is getting reset.Debug log is attached belowTue Apr 19, 2022 10:21:53: The stack pointer for stack 'CSTACK' (currently ...

I have done an SPI transfer only with DMA and working fine, but when I need to do a daisy chain configuration its not working. I am suspecting the NSS signal.below is SPI configuration#define SPIx_Mode SPI_MODE_MASTER #define SPIx_Direc...

Thanks KnarfB for the fast response. It worked.

Hi JWThanks for updateAm using STM32F427.I want to update DutyCycle of a PWM timer at every 2us, so I made an array of 25 values and called HAL_TIM_PWM_Start_DMA(&TIMx_handle, TIM_CHANNEL_1, aCCValue_Buffer, SIZEARRAY);I have configurated DMA in circ...

Hi TDK,Thanks for the fast response.Disabled TI mode and GPIO is used to control the NSS signal (manually).This solved my issue.

I have configured 2 SPIs in DMA and I need to get callback for both SPIs (HAL_SPI_TxCpltCallback). I am able to get callback when tried individually, but simultaneously used its causes build error. Error[Li006]: duplicate definitions .

How to improve the speed of SPI-DMA operation. Basically I want to avoid waiting in while() after transfer of data.

Code reset with message "Tue Apr 19, 2022 10:21:53: The stack pointer for stack 'CSTACK' (currently 0x2002FFE8) is outside the stack range (0x2002FFF8 to 0x20030000)"

I want to generate a PWM signal using DMA TIMER, in which the duty cylce should change in very frequently. Till 10 times the Duty Cycle changes with out any issues after which when I increase the array size the waveform is getting not correct. Kindly help

STM32F4 SPI-DMA with daisy chain not working. Problem with NSS signal.
