some digital compas come with serial or parrarel interface. you can connect it to your uC just like you connect any other peripheral.try to find some digtal compass literatur. learnd about its connection and data interface.
agree with john. try to understand the physical characteristic of your uC choice. coz, when you make a real hardware there will a lot of trouble if you dont understand your hardware at all.
your program will respond to pulse applied to your uC T0 pin. when a pulse apllied, it will roll the value on port1. any way you won't notice it cos, the clock frequencies is too high. try to add some delay instruction.
Ive the same problem with my lcd. is there any hardware input protection? coz i use a parrarel lcd which have to use flat cable as a connection interface.
i think read back the lcd is not the solution, the problem keeps accur sometimes.
i tried to tied the metal case to ground/earth terminal...
Could someone help me???!
i use microcontroller to control 2x16 matrix LCD and its all bundled in a metal case. Sometimes the lcd just goes blank (but the controller still works) when i put it near another equipment that produces EMC (selenoids, Relay, etc.) and or AC line noise.
1. I've tried...
which one is the most ideal terminal connector for connecting some of rs485 devices?is it okay if i just use and ordinary terminal connector (DT-126 screwed connector)???????????
CLK and square wave
go for banjo!!!i wonder you have the time to explain it.
for the simplest, yeah man it look a like. clock is the square wave needed to drive the device.but still you need to study its clock requirement (it timing dude!!) and its explained in time diagram on every device...
yo guy and rosa don't bother-up!!555 ic will do the job. or just use some hexinverter ic and it will do the job too as long as you calculate it precisely;D
