Yeah, I guessed that, but after reading on minimum voltage operation conditions for successfully and reliably making contact in electromechanical relays, doubt started to set in.
Hi all,
I'm looking at a 12V relay rated for 30VDC - 230VAC loads. My question is, will 30VAC loads be just as well within this operational range?
Item is a Velleman VR10V121C .
Cheers
Alex, or anyone else,
I have another minor question which I couldn't find a clear-cut answer to. If I'm servicing an interrupt, but ISR is halted by another interrupt with a higher priority, will the first ISR resume and complete after the higher priority ISR finishes?
This is assuming that...
I did read the Insider's Guide for the LPC2300 but found the manuals gave me clearer answers to my questions and troubles at this point. My previous experience is with the 8051, so the ARM7 is a different beast altogether.
I cannot understand how I managed to miss that. Many thanks.
Also, that tool seems to be excellent! I'm programming everything manually to get a better understanding of the LPC, but that program looks golden.
Thanks again.
I'm now thinking of setting up all the GPIO monitoring in software without using external interrupt modes, thus being able to monitor and control state changes.
Again, any input, suggestions or comments would be greatly appreciated.
Dear all,
Beginner here.
I'm programming an LPC2368 board (ETT CP-JR ARM7) and am setting up P2.0 - P2.7 as GPIOs with rising edge interrupts. As far as the user manual suggests, when an interrupt occurs it will generate a VICVectAddr17, which is shared by EINT3 and all GPIO interrupts.
Since...
I see that voltage drop will be a problem, will need to see how to work around that. I think a simple mosfet should take care of it. Thanks again for the heads up.
Was looking in the manual, but somehow skipped the datasheet. Apologies for the trivial question, I'm a beginner of sorts.
Reason I was thinking that was because I had no idea of the current draw/ internal input resistance and didn't want to risk frying any pins.
Thanks alot for your input.
I'm connecting a 3.3v signal to the GPIOs on Port 2 of the LPC2368.
Apart from the usual pullup/pulldown resistors, I suspect there needs to be an additional resistance between the voltage pickup point and the input pin. I could not find details of this in the LPC2368 manuals, any guidance on...
Hi all,
I am using a Nuvotem Talem ASM-010 current sense transformer (**broken link removed**) together with a TI INA126PG4 instrumentation amplifier (**broken link removed**) connected to the ADC channel on my LPC2368 board (ETT CP JR ARM7). The ADC should finally be seeing a resultant...
