Has anybody tried it?

I want to add some voice confirmation to my project (18f252 + multiple 16f818 i2c slaves) so I tested it today. It works indeed but I get a very very weak signal (I can't use ...

Hi!

Well, 1A is the maximum peak load I would need with everything turned on, in normal operation I guess it consumes no more than 300/400mA...

...but, ok, you're right, it's no problem to use A ...

Hi all Very Happy

Well, yes, I need 5V regulated supply as I'm using some other components requiring 5�0.2V, I guess it's no other choice...

I'm now taking a look at National's [url=http://www.natio ...

Hi guys!

I guess this is kinda off-topic but anyway...

I'm building a PIC based microbot (1x18f252 + several 16f818 slaves) and now I'm in the bussiness of powering it. I was planning to use thr ...

The problem is caused by this line of code:
setup_spi(FALSE);

Thanx for the quick answer!

Manually setting PORTC as inputs with set_tris_c(0xFF); doesn't solve the problem, maybe RS232 routines are overwiting this setting??

My pull-ups are 2k2 each. In 'Sl ...
