HALCOgen NHET Assembly Code

Hi

In HALCoGen we donot create assembly code we directly generate the required opcodes in the het.c and het.h

I would recommend you to use HET IDE tool if you want to develope custom assembly code. HET IDE ( simulator for NHET) can be downloded  from http://www.ti.com/tool/het_ide

Thanks for the reply Prathap.

Can you tell me what the function capGetSignal available in the het.c will do? I am using this function function for measuring the period of input signal, but not working.

I would like to know what is the instruction used for PCNT: Capture Period 0 (highlighted below) in the below code. 

// Code from the het.c  

/* PCNT: Capture Duty 0
    *         - Instruction                  = 25
    *         - Next instruction             = 26
    *         - Conditional next instruction = na
    *         - Interrupt                    = na
    *         - Pin                          = 10
    */
    {
        /* Program */
        0x00034E00U | (3U << 6U)  | (10U),
        /* Control */
        0x00000000U,
        /* Data */
        0x00000000U,
    },
    /* PCNT: Capture Period 0
    *         - Instruction                  = 26
    *         - Next instruction             = 27
    *         - Conditional next instruction = na
    *         - Interrupt                    = na
    *         - Pin                          = 10  + 1
    */
    {
        /* Program */
        0x00072000U | (0U << 6U)  | ((10U) + 1U),
        /* Control */
        0x00000000U,
        /* Data */
        0x00000000U,
    },

Hi Bindu,

As the name indicates it is used to capture the Period of the PWM. The instruction above is used to capture the Duty cycle( based on the Polarity you selected in the HALCoGen GUI) .

Prathap,

I want to know what is the instruction used for the below value. It is not the PCNT. As you informed it is hand written, so i would like to know what is the instruction used for this. As capturing of period is not working as expected.

0x00072000U

Hi Bindu,

The opcode does not look right. Could you please give me following details to help you

1) HALCoGen Version used
2) Family and Device selected in HALCoGen for generating the code
3) NHET / HET TAB - Snap shots ( All tabs under HET / NHET) .
4) Zip the generated code and attach.  

Best Regards

Yes. Prathap. The ope code does not look correct. I am using the HALCOgen Version 2.07, which came with the TMS570 MCU developement kit. I have choosen the TMS570LS20216SPGE processor to generate the code. You can see this with the default settings of of NHET/HET.

When i though, something is wrong with this opcode, i downloaded the 2.10. But could not able to run it. It may because of two version of HALCOgen. If you have nay idea, please help me about this installation.
