Halcogen V4.02 PCNT Problem

Hi Chethan,

I don't think that anything in the HET code has changed, and this is what will be performing the frequency measurement.
I don't have HalCoGen v3.02 installed anymore. Maybe you could do a diff for us on the file 'het.c' especially the array that starts here:

/** @var static const hetINSTRUCTION_t het1PROGRAM[58]
* @brief Default Program
*
* Het program running after initialization.
*/

static const hetINSTRUCTION_t het1PROGRAM[58U] =
{
....

}

This is where the HET program that performs the capture function is actually stored (in binary format).

I don't think you'll find a difference though.

What does the failure look like ? (I mean, when you say it's no longer working, where do things break down? Are you using interrupts but no longer getting the interrupt for example?)

Hi Anthony,

Thank you for your response.

only 2 changes i have seen in both versions.

Halcogen V4.02

1. 

typedef volatile struct hetInstructionBase
{
uint32 Program;
uint32 Control;
uint32 Data;
uint32 rsvd1;
} hetINSTRUCTION_t;

2. HR Clock 90.00MHz, LR Prescale 7

Halcogen V3.02

1. 

typedef volatile struct hetInstructionBase

{
uint32 Program;
uint32 Control;
uint32 Data;
} hetINSTRUCTION_t;

2. HR Clock 80.00MHz, LR Prescale 6

and when i compile it will give 5 warnings in sys_link.cmd file this is already discussed with onother thread.

Problems:

1. When i call the function it result will be always zero and this is happen only in freertos

My Code :

static void vTask_FOR4 (void *pvParameters){

hetSIGNAL_t Capture;
char data[40];

(void ) pvParameters;

capGetSignal(hetRAM1,cap0,&Capture);
hetInit();
for(;;)
{
capGetSignal(hetRAM1,cap0,&Capture);
sprintf(data,"%f\n\r",Capture.period);
UART_SendString(data);

}

}

but this is work in Halcogen V3.02.
