I'm trying to call a sub procedure at the start of a programme as a default condition. Then send the chip to sleep. On an interrupt the same function is called. I have a error message "Reentrancy is not allowed: function 'test1' called from two threads subtest.mbas". I don't ...

some characters lost when chip is in sleep mode and sim868 send some data to PIC. I have seen the datasheet and found out that "AUTO-WAKE-UP ON BREAK" but I don't know how to use it properly. Only a idea, if you don't is using the external ...

HI, Project is a SIM868 and PIC16F1829. PIC chip doesn't work properly with UART interrupt. some characters lost when chip is in sleep mode and sim868 send some data to PIC. I have seen the datasheet and found out that "AUTO-WAKE-UP ON BREAK" but I don't know how to use it properly. Also ...

... with windows XP or 7 Under Win 10 I get a UAC request for an admin password every start up of MB7. As it is a work machine the system goes to sleep after an interval of no activity and always asks for an admin password (not user) to start again. It is fine running under admin but that creates ...

... Attached is the program. RDM6300 you can buy it on Aliexpress , Amazon and other places. Price is from 1.25USD and up. Thank you for help. Go to sleep now as it 1:30 in Toronto. I am happy

... If CMOUT.0 = 1 then ' Battery check For i=1 to 10 Sound_Play(900, 500) ' Play sound of 1 KHz in duration of 500 ms LED=1 Delay_ms(50) LED=0 next i SLEEP end if Delay_mS(1000) SIN_PWM() end.

... the ADC register to a binary string (I don't see why), as an experienced programmer you should be able to create a routine for that in your sleep, assuming you know how to test a bit and what ascii values '0' and '1' are.

Now all is working thank you

Glad to hear it works :) . I use similar processor and it's enough to switch these two bits 'before sleep PWM1OE_bit:=1; // disable output PWM1EN_bit:=1; // disable PWM 'wake-up PWM1EN_bit:=1; // enable PWM PWM1OE_bit:=1; // enable output The PWM pin is defined as low level ...

A little feedback: I tried following code, before sleep: PWM2CON.6 = 0 'Disable PWM output PWM2CON.7 = 0 'Disable PWM module TRISA.0 = 1 'Select RA.0 as input ANSELA.0 = 1 'Select RA.0 as analogue input (save energy) But it was not working. I move ...

... can externally ensure valid logical state of such inputs. Floating inputs can lead to a significant current flow through the input stage. After sleep loop, i will reinitialize the whole hardware. There's no need to. It's enough to manipulate two bits to stop PWM and disconnect it from output ...

Ok. I understand. I will try to set the Tris Bits all to input, to save more power. After sleep loop, i will reinitialize the whole hardware. I run the sleep loop 6 times with WDT time from 16 seconds, because i will need ~96seconds. I could also do it with 3 X 32seconds ...

Sorry, it wasn't clear what you intended. If you want the output low you have to ensure it before going to sleep. Otherwise the state of PWM pin is indeed unpredictable. Best disable the PWM output pin (PWM2CON.OE=0) - having TRISA and LATA appropriately set at initialization ...

I don't need the PWM at sleep.
So thought, if i set the PWM clock to Fosc.
When it goes in sleep mode, PWM stop.

But you see it on the oscilloscope, that the PWM starts with highest duty cycle
This is the problem.
In sleep mode, the PWM should be low.
