RM46 and HALCoGen: no interrupt handler generated for eQEP1 interrupt

Jan Cumps

Other Parts Discussed in Thread: HALCOGEN

When creating a HALCoGen project using the eQEP driver for the RM46, and selecting the interrupt 110: eQEP1,
the handle named eqepREG1 is not generated when generating code.

This seems to be different than with other interrupts. They typically generate code that results in one of the notifications in notifications.c being called.

I can't find that void eqepNotification(eqepBASE_t *eqep,uint16 flags) is called when enabling interrupt 110.

My project fails to compile with error:

../HALCoGen/source/sys_vim.c", line 182: error #20: identifier "eqep1Interrupt" is undefined

A procedure void eqep1Interrupt(void) is generated in eqep.c.
Still the compiler complains.

I worked around this by adding the following to sys_vim.h:

/* USER CODE BEGIN (3) */
extern void eqep1Interrupt(void);
/* USER CODE END */

For other ineterrupts, HALCoGen creates this at code generation time.

Jan,

I have passed your question to the Halcogen team. They will get back to you shortly.

Thanks and regards,
