This is my project to control the shifting of my auto transmission (like BMW and Mercedes does with their E-shift or touch-shift or whatever they call it)....

Hi ?Brian? I believe that your problem is power supply or noice from the car ... remember to place 100nF decoupling capacitors as cloose to the pic over Vdd ...
High value capacitor ( 1000uF or more) closely to your relays and solenoids, the supply must go first to your load, then to capacitors and only then to your...
My impression is you never need to read the cursor position because you may put the cursor at the position you want. So why to read it ? HD44780_position1 ( 0...

Lasse Madsen: I will try that, just on the opto isolator outputs right? And i am running 3000uF between Vdd and Gnd so that shouldn't be a problem. And may...

... The first thing is to get that configuration right. Use plenty decoupling around the PIC (0.1uF as close to the PIC power pins as possible, a 10..100 uF...
Brian, you have the most common automotive problem; i've guess your ground is common isn't it ? Does not count you have a totally optoisolated command if the (...

Thanx Vasile for making the "abacadabra" clear for an amateur like me... ;-) ... [Non-text portions of this message have been removed]...
Great article, you where ahead of me ;-) One remark about 'lost events'. I'm not having extensive experience with this but from the Midrange Manual I found the...
The decoupling are very close to the PIC pins, and I am using a 4Mhz ceramic resonator with built in caps. And there is a diode (reverse diode or some name...

... Go for a 16f628, cheaper than an f84 and still more efatures (like internal 4 MHz clock, fine if you don't need the accuracy of a crystal or resonator). To...
Be systematic. Take small steps. 9V battery + 7805 + PIC works OK? Add relais driving circuitry, galvanicall isolated but not powered yet, works OK? Add power...
I actually didn't find out about the 16f68 till just recently, and i have a few 16f84's that I havn't burnt up yet. Once i get this to work i will need way...

You got it, only when the contacts see .2A of current, I can not replicate it on my PSU probably because of the .1A 12V max output. So a compact circuit like...
