core 2.7.4 to 3.0.2 problem in interrupt and timer1 #8581
Comments

Not sure, but it seems very odd why littlefs is in the dump and it's never
called....

Hi
So my project : ESP12E Wemos D1 mini, 4 Mo, core 2.7.4, Sloeber env. on
Windows7
Problem : My code work perfectly with core 2.7.4 and crash with 3.0.2. The
crash is always around the same place : in the interrupt of the timer1. In
short, I made a dimer : when I have the zero cross interrupt, I start the
timer1 to activate the SSR relay for a delay.
I really made hundred of try but always the same problem.
Any ideas are welcome :)
Regards,
Lionel
The relevant code is :
`
#define SSR_TURN_ON_us 50
uint8_t SSR_PIN;
int8_t LED_PIN = -1;
static bool Top_CS_ZC = false;
static volatile bool Tim_Interrupt_Enabled = false;
static volatile bool Is_SSR_enabled = false;
static volatile float SSR_COUNT = 0.0;
// Send SSR pulse after delay
void IRAM_ATTR onTimerSSR(void)
{
if (Is_SSR_enabled)
{
if (Top_CS_ZC)
{
digitalWrite(SSR_PIN, HIGH);
Top_CS_ZC = false;
Timer_SSR.setInterval(SSR_TURN_ON_us);
Timer_SSR.startTimer();
}
else
{
digitalWrite(SSR_PIN, LOW);
if (LED_PIN != -1)
digitalWrite(LED_PIN, HIGH);
}
}
}
// Zero cross was fired
void IRAM_ATTR onZC(void)
{
Count_CS_ZC++;
if (Is_SSR_enabled && Tim_Interrupt_Enabled)
{
if (LED_PIN != -1)
digitalWrite(LED_PIN, LOW);
Top_CS_ZC = true;
Timer_SSR.setInterval(SSR_COUNT);
Timer_SSR.startTimer(); <------------------- here is the line 120
}
}
void IRAM_ATTR startTimer(void)
{
timer1_write(_timerCount);
timer1_enable(TIM_DIV, TIM_EDGE, _loop);
}
`

I see this is only part code, the stack might run out with that many calls
on it :-)

What's Timer_SSR? What's the exception code? Is this some 3rd party library or are you the author? |
|
You've not given us an MCVE, either, so there's not much other than guessing we can do now. FWIW, you've placed your IRQ handler in IRAM, which is good. But, have you placed all of whatever class Also, if you have |

Hi Many thanks for your reply and to format my post (I used the correct quote but ....). Timer_SSR class code : |

Hi again ;) You give me an idea : I make this test :

Hi again !!! I have made a simple sketch that produce the crash. Just run the sketch on a Wemos and wait a little for the crash ! lol The Interrupt_Crash.ino sketch and the dump : |

Why not use the ticker library??

Yes, it is part of the whole code. But I have tested the rest separately
and "normally", it is OK.
LittleFS is present because I store regularly some data (and also for the
web page).
Timer_SSR is the class that encapsulate the timer1 access. All is in IRAM
. Here is the code below.

Exception cause: 0
Sorry but what is : MCVE ?
I think I respond to all your questions (and sorry for my poor English !!)

The goal is not to use another library ! ;) |

Hi, I also test with core 3.0.0 and I have the same crash. I also test with Arduino IDE (I have 1.8.13), same crash. Core dump for 3.0.0 : |

Hi mhightower83, Thanks for your attention of my problem :) |

I would switch to using integers in the ISR code. |
|
Hi, Ok, I switch to uint32_t in place of float. |
|
I have another question : In the interrupt, I use some variables (SSR_PIN, LED_PIN, Top_CS_ZC, ...). |
|
If a variable is read-only by the ISR, there is no need for special treatment by the compiler. For I don't see a requirement for
Yes. However, IRAM is generally in short supply compared to DRAM and brings additional access restrictions the compiler will not handle. For data access, it will be a little slower than DRAM and access is restricted to aligned 32 bit words. I see it as an option when DRAM is running critically low, and you can sacrifice a little speed and IRAM from the cache for more storage. See https://arduino-esp8266.readthedocs.io/en/latest/mmu.html for more details on using IRAM for data storage. |

Hi
So my project : ESP12E Wemos D1 mini, 4 Mo, core 2.7.4, Sloeber env. on Windows7
Problem : My code work perfectly with core 2.7.4 and crash with 3.0.2. The crash is always around the same place : in the interrupt of the timer1. In short, I made a dimer : when I have the zero cross interrupt, I start the timer1 to activate the SSR relay for a delay.
I really made hundred of try but always the same problem.
Any ideas are welcome :)
Regards,
Lionel
