Hello,

I am trying to implementing PID in Systick Interrupt handler.I get this error after compilation in Keil MDK '' C:\Keil\ARM\CMSIS\Include\arm_math.h(268): error: &sharp5: cannot open source input file ''ARMCM4.h'': No such file or directory''. I added arm_cortexM3l_math.lib to my Project List but no Luck.I need help in this aspect.Also, I think I have a problem with Initailizing Kp, Ki & Kd '' arm_pid_instance_q15 '' struct.Please can someone tell me if my inialization is correct and if I did the right thing on CMSIS PID.

-------------------------

/**

* @brief Instance structure for the Q15 PID Control.

*/

typedef struct

{

q15_t A0; /**< The derived gain, A0 = Kp + Ki + Kd . */

&sharpifdef ARM_MATH_CM0

q15_t A1;

q15_t A2;

&sharpelse

q31_t A1; /**< The derived gain A1 = -Kp - 2Kd | Kd.*/

&sharpendif

q15_t state[3]; /**< The state array of length 3. */

q15_t Kp; /**< The proportional gain. */

q15_t Ki; /**< The integral gain. */

q15_t Kd; /**< The derivative gain. */

} arm_pid_instance_q15;

------------------

MY CODE WITH COMPILATION ERROR

------------------

&sharpinclude ''stm32f10x.h''

&sharpinclude ''arm_math.h''

int main(void)

{

uint16_t SpeedError,CorrectedSpeed; /* Variable that holds error*/

uint_16 resetStateFlag = 0;

RCC->APB2ENR |= RCC_APB2ENR_AFIOEN | RCC_APB2ENR_IOPBEN;

//PB0 & PB1 =>Alt Function Push Pull O/P | PB6-PB7 Alt Function Open Drain

GPIOB->CRL = 0xFF4444AA;

GPIOB->CRH = 0x44441111; //Configure PB8-PB11 as Output (Push Pull)

GPIOB->ODR = 0x00000000;

arm_pid_instance_q15 S; /* PID S Instance Structure*/

S.Kp = 2300; /* Change the member Kp of S to have the value of 2300 */

S.Ki = 150; /* Change the member Ki of S to have the value of 150 */

S.Kd = 0 /* Change the member Kd of S to have the value of 0 */

arm_pid_reset_q15(&S); /*resets the state buffer to zeros*/

arm_pid_init_q15 = {&S, resetStateFlag}; /* Initialize A0 & A1 from Kp, Ki & Kd */

if (SysTick_Config(SystemCoreClock / 1000))

{

/* Capture error */

while(1);

}

while(1)

{

}

Regards

Slim

void SysTick_Handler(void)

{

CorrectedSpeed = __STATIC_INLINE q15_t arm_pid_q15(&S,SpeedError); /*PID out processed output sample*/

}

The error is not about adding library files, you need to set up the ''Include Paths'' for the project to point at the assorted directories you have include files stored in related to the project. If the inclusion isn't required you might also want to consider if you have the right defines for the project too.

Tips, buy me a coffee, or three.. PayPal Venmo Up vote any posts that you find helpful, it shows what's working..

Dear Sir:

Please give me help.

I use IAR 6,60.1.5104 and try to run arm_fft_bin_example_f32.c

I copy arm_fft_bin_example_f32.c and arm_fft_bin_data.c under C:\...\STM32F4xx_DSP_StdPeriph_Lib_V1.1.0\Project\testfft\

and copy EWARM to same directory and add C compiler->Preprocess-> Additional include directories as

$PROJ_DIR$\..\

$PROJ_DIR$\..\..\..\Libraries\STM32F4xx_StdPeriph_Driver\inc

$PROJ_DIR$\..\..\..\Utilities\STM32_EVAL\Common

$PROJ_DIR$\..\..\..\Libraries\CMSIS\Device\ST\STM32F4xx\Include

$PROJ_DIR$\..\..\..\Libraries\CMSIS\Include

''Defined symbols'' as

USE_STDPERIPH_DRIVER

STM32F427X

USE_STM324x7I_EVAL

When I ''rebuild all'' it give me an error as following

arm_fft_bin_data.c
