Hi,
1. Do you know if tick is negative at line that you marked
if (ticks < _REG32(tmr->pwm_regs, PWM_CMP0)) { <====question code
In my program : PWM_CMP0=0xffff, PWM_CMP1=0xffff, PEM_CFG=0xc0001209, ticks
=0x6a
my observation: 0x6a written in PWM_CMP1, this trigger pwm interrupt
(fe310_pwm_cmp1_handler)
and the handler call fe310_tmr_check_first again, then trigger pwm
interrupt, and so on..
2. I am sorry I can not share project with you, it is company project.
I can provide program running info
3. I have a question about hal_timer_cnt function .
how does the code check overflow condition?
Thanks for your help.
--------------------------------------------------
static uint32_t
hal_timer_cnt(struct fe310_hal_tmr *tmr)
{
uint32_t cnt;
int sr;
uint32_t regs = (uint32_t) tmr->pwm_regs;
__HAL_DISABLE_INTERRUPTS(sr);
cnt = _REG32(regs, PWM_S) + tmr->value;
/* Check if just overflowed */
if (_REG32(regs, PWM_CFG) & PWM_CMP0) { <====question code
cnt += _REG32(regs, PWM_CMP0) + 1;
}
__HAL_ENABLE_INTERRUPTS(sr);
return cnt;
}
