STF and SD can be connected with the switch.
About speed control. Did the original scheme control velocity? If there is no more connections, so it looks like the motor rotates at its maximum speed always.
Anyway, to test the motor it's better to use a trimpot to control velocity.
As far I as know, you cannot make external layers (top and bottom) as plane layers, instead of that you should place polygon plane with the desired shape (you can just make a polygon repeating the PCB shape with small gap between the poly and the board edges) and connect it to GND.
It doesn't mean that they are both not connected to GND, it means that there is no connection between two objects within one net.
As for your case, I don't see the bottom GND plane. Do you have a GND polygon? Is it shelved? To get rid of that error the polygon must be filled (restored and...
If you define AND initialize array in one line you don't have to put the array size in the definition as Easyrider83 suggested. The array size will be calculated during compilation.
But if you don't initialize array elements in the definition line, you must explicitly write array size.
Re: How to set program counter to illegal address while code is running ?
I didn't try it, but it should work. Try to use pointer to a function like this:
int (*func)(void) = 0x00FFFFFC;
func();
Re: How does a VPN works
VPN is not a particular protocol, but rather an abstract description. VPN may be point-point, point-network, network-network. Particular implementations of VPN include PPTP, PPPoE, IPSec, L2TP etc. MPLS is more complex method, and it is used to create VPN. I'm not so...
Re: How does a VPN works
VPN is a Virtual Private Network. It does nothing with the path via Internet routers. VPN packets may be send the same route as usual packets.
The point of VPN is to create a secure and convenient connection over global networks using data (useful data) encryption, so...
In atxmega you must enable interrupt controller with required interrupt levels (priority) in PMIC.CTRL. Then enable appropriate interrupt in peripheral control register (for USART that would be USARTxn.CTRLA). And finally enable interrupts with "sei" command.
Moreover, there is no LEDs toggling at all. #defines define (sorry for tautology) only constants, but they are not macros, so after the preprocessing the compilier will see only 1's and 0's followed by semicolon. Your previous version was correct:
LED1 = LED1_ON;
Task2 has LED1_OFF, but not...
"Switch-case" statement is equivalent to "if-goto". So if you do the following:
switch (task)
{
case task1:
if (task == task1)
DoSomething1();
break;
}
that makes no sense as case already substituted if and you have two if's for the same condition. But if you...
I'm not so familiar with gas tubes, so I'm not sure about some terms, but in general Google translate is almost correct, although some lines are not.
Current of <12 mA --> Indication current <12 mA
Uncertainty error (reduced) <4% --> Nonlinearity error <4%
A is direct inclusion; 6 - switching...
In general, draw a desired shape (usually at mechanical layer 1), select all external primitives, then Design->Board Shape->Define from selected objects. To make a cutout, select all internal primitives forming closed shape (one shape by time), then Tools->Convert->Create board cutout from...
