Hi
I use Altium Designer. I need to have several connection types in the same polygon. some component direct connection and some components relief connection.
how can I do it?
Hi dear
I need to use a switch to check the state of a part but the line and switch are located in a long-distance and noisy place.
I adjust R1 to drain 10mA when switch S1 is closed and CD voltage is 3 volts. I'm confused to use 24V instead of 3V.
what`s your idea? is there any better...
Hi dears
Anyone has any advice to become easier and more effective to write code for external peripherals?
when you use a microcontroller you have a debugger that is so useful to check registers and the state of the MCU.
I worked on QuadSPI flash and make some basic functions to use it. but my...
I just simplified the circuit to this new circuit.
please attention, I didn't feed any voltage to pins 1 & 2 of MOC3063.
and there is no load for the circuit so it expected any heat if proper operation.
It seems TRIACs fire automatically.
TNX Brain.
So if I replace TRIAC 1 in schematic one with a simple wire any change does happen?

Something strange happend.
3 and 4 completely broken and 2 damaged too.
But I didn't connect the motor to the circuit and I didn't feed any signal to Optotriacs. I just linked 400V to...
Hi dears
I wanna control the direction of a 3 phase AC motor. there are two types of circuits for it.
and
the lines voltages are 400 volts and I choose BTA12-600CW.
The 600 volts for BTA12 is enough or do I need a higher voltage TRIAC for the purpose?
It used 5 TIRACs in image 1 and 4 TRIACs...
I drive an AC motor perfectly. 40w and 60w single phase AC motor. I have Snobber and it's complete.
but TRIAC born after several months when I use bulb lamps.

voltage is about 220V AC
I have a problem with BT136, not MOC.
If you have good note let me know about that.
TNX...
Hi
I used circuit below. it seems simple. it works properly but after some while the BT136 born.
I guess it's lead by dI/dT limitation.
let me know about your ideas? how can I solve the problem?
Re: released micomontroller`s IO pins and noise
which state is better?(Input,Output,Analogue)
So what about power consumption?
less noisy condition?
I`m with output but some companies suggest analogue input.
hi, dears.
I have a question about the pins that unused in microcontrollers.
I want to link all of them to each other directly and pull down them via a 100 ohms resistor. can direct linking of IOs make problems in my design?
notice you that all IOs are input by default and I let them still in...
so dear, what`s your suggestion to control or limit this massive current in cases that we have to work with large current.
resistor? or better method existed?
hi dear
I faced with a problem when I work with timers interrupt sub routine.
I used avrstudio 6.2. I wrote this code.
// ***************************** Timer 2 compare Subroutine *********************************
// Start of function
void ISR (int TIMER2_COMP_vect){
rsig_on...
any no one?!!
example for module that I need, EM18. but it is short range.
if you suggest me IC too it can help me a lot.
I think there are more choose for ICs.
