This first use will be a simple one - a virtual 555 chip to send a coded 38 KHz infrared beam from one unit to the other... the units are solidly mounted, twelve feet apart on my windows (they open my blinds) and I wish to make one a master and the other a slave. The resonators will also force the two stepper motors to operate at identical speeds... I've picked 4 MHz, as my not-so-critical timing in all my current projects is based on that, and I can read a TV-remote, and operate my motors just fine with the algorithims I've already written at 4 MHz. Faster is not better for the time being... in fact, faster creates problems. ---> So I will purchase two dozen CST4.00G0H6 resonators (with the internal capacitors) - but then my sources conflict: ++ my version 1.1 (paperback) manual says I need a 100K parallel and a 470? series resistor... ++ a pdf version on my computer says I just need a 1Meg parallel resistor. ++ my SX-tech board has room for a resonator, but I see no resistors in the circutry... which combination is correct ? ------------ ...and I will have to pop them in and out during programming and de-bugging, right ? ? ? --- are little 3-hole holders made just for them, or can I just cut down some collet-style sockets ? thanks.
