Re: PWM frequency
That could be the problem, i already solved it by using timer0, but i did not know why it solved it. i thought pwm was controlled by timer1, thanks anyway

PWM frequency
Hi, A nother problem, a nother topic... My Ecio-40 is programmed for PWM, in the prooerties menu is written that it is +/- 48kHz, but when i meassure it, it's 3kHz. Any idea what can cause this, more important, how to solve this? When i'm controlling a motor with it, it makes a high beep, probably ...

Re: CCP pins + Vreg broken?
Thanks for the expanded response, I replaced the L293D in a manner that i can't even tell anymore which one i replaced, so it had exactly the same name, i blew up the original one with the same motor, but switching it on/off too fast and frequently. I was supplying from the baseboard with the termin...

Re: CCP pins + Vreg broken?
Hi, I don't think I clearly told you my set-up. I was driving the motor with the power E-block EB011. So I would think the CCP pin did not draw alot of current, just to put the signal to the IC of the EB011. My regulator is the one on the EB061 (ECIO base board) and considering i was using 12V, it d...

CCP pins + Vreg broken?
Hello, I think i like to break stuff because i have yet again a fault in my hardware. i was operating a 12 watt motor 12v/1amp, with pwm ccp1 and after some time the motor kept bieing in the on state. So i grabed my multimeter and checked the voltages. CCP1/RC2 was +5V, CCP2/RC1 was 0V and the outpu...

Re: ECIO+LCDportA+Analoge+pull-up
"What is happening when you try to use both together? Is the LCD failing or is it the pull ups?"
It where the pull-ups that where not working.
With intcon2 = intcon2 & 0x7F; it works as intended, thank you very much

Ok, not really an explosion, but there was some smoke... I was driving a DC motor (too powerful) with PWM on 2 different EB011 boards for testing reasons, after switching direction a couple of times repeatedly, the L293D chip which was driving with PWM started to smoke and pretty much died. I knew t...

Re: EB022 and EB011 board questions
I'm starting to wonder if this application is even possible, because I'm not sure if there is a Microcontroller that can support all these's E-blocks. Some advice on that please?
ps. there is also a LCDscreen needed in this application, not mentioned before.

Re: Flowcode 4 / Miac compile error
Hi Medelec,
thank you very much, this explains all my misunderstanding with strings. I have programmed in C before with strings, that's why i found it odd i could not assign them like that, but i see you can, i just need a different flowchart icon.
thanks alot!
