Hi all,
spend more than a day to solve my problem, no success......
I have written a program for a model railway, controlling a car.
It has a build in ESP D1. So far so good. all the routines work fine.
Now the next step, to control it remotely with an onboard IR receiver and a transmitter.
I have split all the actions into several loops.
the IR receiver loop are remote() and decode()
If I have both active I see the codes I transmit.
If I active the loop Flashleds it still works fine.
But if I active the loop blinker ( I want to control the left and the right car blinker) it goes wrong.
What happends:
After startup all the codes I sent are recognised. But as soon as I sent either the code for the left blinker or the code for the right blinker the right blinker starts blinking but from then on no codes are seen by the receiver.
This is a result seen on the serial monitor:
remote_irResult DEC / HEX: 28 / 1C
remote_irResult DEC / HEX: 28 / 1C
remote_irResult DEC / HEX: 28 / 52
remote_irResult DEC / HEX: 82 / 52
remote_irResult DEC / HEX: 82 / 52
remote_irResult DEC / HEX: 82 / 52
remote_irResult DEC / HEX: 82 / 5A
remote_irResult DEC / HEX: 90 / 5A
remote_irResult DEC / HEX: 90 / 5A
remote_irResult DEC / HEX: 90 / 5A
remote_irResult DEC / HEX: 90 / 5A
so a number of codes are listed, as soon as I sent code 5A (line 140 on the sketch) for the right blinker its the last code I see.
Its even worse if I uncomment everything in the main loop. Then I do not see a single IR reading
Hope for some good ideas, code below:
/*
V10
To do:
Richtingaanwijzers werken maar nog remote aan te sturen
Remote aansturen snelheid, maxspeed?
Led helderheid aansturen met analogwrite:
done on Blinkers
done on Brake
not possible on Flash lights
on front and rear lights?
D0 is planned to be used for IR data input, temporaly D5 is used for cruise,
has to be combined, one output free for front and/or rear lights

The ESP module uses a different numbering as the Arduino's.

D1 5 Flash
D2 4 stopplace (IR receive Bottom)

D4 2 Brake Led
D5 14 IR input Front / later output rear red lights
