Hello
I am looking to create a system that should allow me to manage the start / stop of a module to have a great autonomy. In ON mode the module consumes 5 ma vdd = 3 Vdc. The PIC is an 18F66K22. The first attempts with a first program allow me to obtain a result; 60sec sleep, 1sec ON, current 8 uA 3Vdc in sleep mode. For this project, I must use an ADXL345. The ADXL345 program alone works very well. In summary, separately both programs work well.
I want to start the first program (timer) which after 60 sec of sleep will go into On mode for 10 sec. During these 10 sec ADXL345 must
run the outdoor module for a few seconds. Here are the main parts of the final program which are not working properly. I use Hyperterminal and 2 LEDs to follow the functioning of the final program. I take advice and thank you in advance.

while(true)
{
accel = mesure_accel(); //OK
add_value_double (&buff_accel, accel);
delta_accel = abs( get_max_double(&buff_accel) - get_min_double(&buff_accel));
level_median = get_median_level (&buff_level); //Trie et affiche le résultat
//output_low(pin_G0);
{
sleep_for_x_seconds(5);// 10=20";40=81";30=60";25=50"
output_high(pin_G0); // Turn on LED 2 to show end of sleep.
delay_ms(3000);//1000 1500
//reset_cpu();
}
//While(1)

So, you are running off what supply voltage?.
Internal Vreg disabled?.
What clock rate?.
What is happening wrong?.
Is the ADXL set to switch to low power mode?.
There are a huge amount of functions in what you post that we don't
know what they do, or are meant to do. |

HI Ttelmah thank for your answer.
I do not use Internal Vreg disabled
Clock is 20 Mhz (xtal) and 32Khz
I tested 2 programs 1 to manage the ON / OFF the other for ADXL. Separately they work very well. The on / off program controls the supply of a BLE module
in 3 volts (I made an interface with 2 transitors for that). My goal is to combine the 2 programs. the ON / OFF program must integrate the ADXL program. adxl
must control on a movement the ON / OFF of the BLE module. Ex: 50sec sleep (off) then 10sec ON if during these 10 sec ADXL moves it puts the BLE module ON then goes to sleep.Normally I can follow on hyperterminal the X, Y, Z values of ADXL. Currently by combining the 2 programs it does not display any of the values.  |

If you are running off 3v, the ENVREG pin should be tied to GND to disable
the Vreg. You still need a 0.1uF capacitor to the Vcap pin, but not the 10uF
normally needed here.
Now problem is you don't show what so many parts of your program actually
do, so it is really impossible to know what isn't working.
You need to show us more to have any hope of getting help. |

Do you really need 5 seconds after power on before using the module?.
Most things take a fraction of a second.
It still does not give us all the 'bits'. However one thing leaps out. Nothing
will set global_interrupts_enabled to FALSE. Result you are going to get
interrupts enabled when you don't want them to be....
You need:
int8 global_interrupts_enabled=FALSE;
To make it start as FALSE. Otherwise once it has been set to 'TRUE',
it is likely to remain TRUE. |

One big issue you may not realise. Your chip does not support 'double'. On the PIC16 and 18, double codes as a single precision float. It only gives double precision on the DsPIC's.
Same applies in several other places. Though you say the code worked.
For instance:
| Code: |
//Unsigned long on a PIC18, is only a 16bit value yet you talk
//about returning 24bits....
unsigned long cmd_adc(char cmd)
{
unsigned int ret;
//same issue here with the temporary variable
unsigned long temp;
i2c_start();
i2c_write(ADDR_W);
i2c_write(CMD_ADC_CONV+cmd); // send conversion command
i2c_stop();
switch (cmd & 0x0f) // wait necessary conversion time
{
case CMD_ADC_256 : delay_us(900); break;
case CMD_ADC_512 : delay_ms(3); break;
case CMD_ADC_1024: delay_ms(4); break;
case CMD_ADC_2048: delay_ms(6); break;
case CMD_ADC_4096: delay_ms(10); break;
}
i2c_start();
i2C_write(ADDR_W);
i2c_write(CMD_ADC_READ);
i2c_stop();
i2c_start();
i2C_write(ADDR_R);
ret = i2c_read(); // read MSB and acknowledge
//Won't work. 65536*RET will overflow the 16bit variable
temp= 65536*ret;
ret = i2c_read(); // read byte and acknowledge
temp=temp+256*ret;
ret = i2c_read(0); // read LSB and not acknowledge
temp= temp+ret;
i2c_stop(); // send stop condition
return temp;
}
|
So in fact your code here is only reading the low 16bits of the value....
Get out of the habit of using keywords like 'long'. Instead use
explicit sizes. Code your variable and function here as unsigned int32.
You call lots of as yet unposted functions referring to 'double', but since
the type doesn't actually exist, these are almost certainly not doing what
you expect. |

Thank a lot Ttelmah for your advice.
what distorts thinking is that software works properly separately.
I will put your recommendations into practice.
Perhaps the best solution would have been to use only
ADXL to turn the BLE module ON / OFF. ADXL becoming the operations manager. As soon as we move him while he sleeps he wakes up
BLE ON / OFF. Yours, I will keep you posted on the evolution because I have very little time to finish. |

If it doesn't display any values, my suspicion is that the ADXL, is not being
woken up. You do understand it'll go to sleep if not accessed?. If you are
switching off it's supply (which you seem to suggest), then it needs to
be re-initialised/configured before it'll work.
The code is so disjointed, and posted in so many incomplete 'bits' that it is
impossible to actually work out how things are meant to occur.
Sequence what you want it to do, then look at how this compares with what
your code actually does.
So if you are turning off the chip, something like:
a) Turn chip on.
Initialise.
Wait to stabilise.
b) Reading as existing code.
Loop to 'b' till time expires.
Turn off chip.
Now sleep.
Loop to 'a' when sleep complete.
You are presumably getting away with the use of int16's, since movements
are small enough to fit in int16 values. Will only give problems with
larger accelerations. |

Thank Ttelmah Very soory for my answer delay.
One problem was this fuse ; #FUSES SOSC_HIGH
The oscillators are running now.
I have another priority for now and i need to post the problem.
My best regards |
