I am running a sequence and a NI-2593 switch card is in my setup. I have a bunch of switch executive calls in my sequence that call the virtual device that corresponds to the 2593 card at various points. Before I make any switch exec calls, all my instruments are initialized with standard initialize VIs that return instrument handles.
Why is switch executive trying to start a new session with the switch card? And why would this fail? It is saying that the process "2593_init failed" .. but why is it trying to initialize the switch.. I've already done that in my code. See picture of error.
Sorry to necro an old thread, but I just encountered this problem today.
In my case, one of the switch cards had been renamed in MAX after the virtual device was created but the virtual device did not update, so it was still trying to point to the old device name.
The Nyquist Digital Call Switch allows users to initiate a normal, urgent, or emergency call from classrooms or other staff locations via an associated Nyquist intercom speaker. This single-gang box type wall-mounted switch uses a full spectrum LED-lit ring to confirm user actions and to indicate status (for example, changing color from a solid color to blinking), or to acknowledge a button press when a user initiates a call or when a call has been terminated. The switch is a capacitive touch type with no moving parts to jam or fail.
Instead of using threads, I would like to be able to switch the C call stack. I.e. I would like to have multiple call stacks "alive" and switch between them by calling a function. This should be conceptually similar to a longjmp but preserve the old/new call stack. The goal is essentially to implement something like "async" runtimes in other languages.
I would like to do this without a library in the "simplest" way possible. My idea is to essentially just allocate a new C call stack and switch to it. Is there any way to do this in C in a platform agnostic way (i.e. without assembly)?
In UNIX, the send() call could have the MSG_DONTWAIT flag passed in to indicate that the operation should not block for completion, but instead return a value to indicate that the operation would have blocked. This would be indicated with an error result and errno set to EAGAIN or EWOULDBLOCK. This context structure should then be saved in some queue to be picked up again in the future to retry the operation. The same queue could have some other context structure in it upon which the send() could be attempted again to see if progress can be made.
The makecontext() and swapcontext() functions is the mechanism classic UNIX systems had provided for cooperative concurrency. It lets a process switch its current execution stack with an alternate execution stack. Because it lets you switch execution stacks, it can avoid the need for defining a state machine structure. The state is intrinsic to the execution stack.
However, it does not avoid need to enable non-blocking interactions with operations that would normally block until completion. Upon receiving an indication the operation would block, you would switch to an alternate stack to retry their previously blocked operation.
GNU pth can provide a thread like programming paradigm. If you follow the provided APIs, it will appear like all your threads are performing block to completion operations, when pth is actually intercepting the calls and performing the non-blocking versions under the covers and context switching on your behalf.
The only way I could do is to run the same code of case 3 and then case 4 then my own computation, I wonder is there a way to call case 3 & 4 directly like calling a function then return back to case 5.
Allows users to switch from an ongoing call to a different call. Users can end the previous call, transfer the caller, or put them on hold for another user. It helps your customer service reps during high-volume calls to easily switch between multiple calls.
While on a FaceTime call on your iPhone, you can hand off the call to your iPad or Mac. To hand off a FaceTime call, your devices need macOS 13, iOS 16, or iPadOS 16 or later. You must be signed in with the same Apple ID on both devices.
The call moves to the new device. On the original device, a banner appears confirming that the call was continued elsewhere, along with a Switch button, which you can tap if you want to bring the call back.
I have checked that switching time between wifi to cell is less than 10 seconds, and ZoIPER reconnect immediately (I can see in Freepbx that the extension disconnect then reconnect in less of 10 seconds).
The call on the PBX is sending and expecting information from the IP(s) that started the call. When you jump networks the PBX is still sending traffic to the IP the call started with. As it stands there is nothing in FreePBX/Asterisk on their own that would do what you are looking for.
Important: This option is available if you chose "Always visible" or "Visible during call" in your Phone app settings. You can switch to RTT on any call, whether you started or received the call.
Tip: On Google Pixel devices, your call transcript is only stored within the Phone app, and other apps don't have access to your call transcript. Other devices might work differently. To find out how your transcript is stored, check with your device manufacturer.
if the switch case is 00 then it light up the first corner
if the switch case is 01 then it light up the second corner
if the switch case is 10 then it light up the third corner
if the switch case is 11 then it light up the fourth corner
The yellow highlighting in QGC is just meant to let you test that a switch is connected correctly to a function. It is not meant to reflect the currently selected flight mode on the vehicle. In the case where you have multiple switches thrown at the same time you are going to get undefined behavior in QGC as to what flight mode you will really get selected in yellow.
Humor me once. Change your flight mode setup where you have one channel on a 3-way switch then assign other flight modes to other 2-way or 3-way switches from other channels. As my example below, CH6 is on a 3-way that has Position, Altitude and Manual, CH9 on a 2-way as Stabilize; using, as you suggested, a QGC Daily Build.
If you look at post #6, when I changed the airframe to a VTOL, the audio call out and icon bar display is correct, per the switch activation of CH9. And for good measure, I also upgraded to v1.8.2 Stable on the VTOL and it was working as well.
But besides that, if you look at my Post #6, with a VTOL airframe type, it does reflect and audio call out the correct flight mode as triggered by CH9 switch on the Tx. As @DonLakeFlyer mentioned, it has to be in the Airplane module/firmware as it seems to work in the Multi-Rotor code.
Hi Pete
The idea is to call the pumpautoStart() from case1 but it seams like the function only runs once when the segmented switch changes state. I would like the function to keep updating when case1 is selected.
On that note, I notice that you have a BLYNK_CONNECTED() command which syncs V14, V15 and V16.
All this does is whenever the device connects or reconnects to the Blynk server it causes the BLYNK_WRITE(V14), BLYNK_WRITE(V15) and BLYNK_WRITE(V16) callbacks to fire.

For your copy, I would recommend associating the appropriate action such as, "Toggle the switch below to [state]" or if your product voice is more informal maybe, "Touch [or slide if the user actually slides it] the switch below to turn [on/off] [state]".
The RS-143 single button call panel substation is designed to be used with the N-8000RS or N-8010RS substation interfaces. It provides a single red call button. The call button can be programmed to report to any master station based on job specification. It requires 3-conductor shielded twisted pair (STP) wiring and mounts in a standard US single gang flush or wall mount box. The optional RS-141 handset for private calling, or a 25V/1W speaker such as the PC-580RU for room announcement applications, can be connected to the call panel station.
I think I am going to have to call out to my DHCP server to find out the subnet for that site off a common tag in both IPAM and Meraki. Then I will take the MAC address from adding the device in Meraki to go back out to Bluecat IPAM/DHCP to set a reservation.
I connected multiple cameras and microphones, speakers to my computer.
There were no runtime events or methods discovered when I switched the specified camera to a different camera (same for microphones & speakers).
