Talon sr, or SRX?

[jojoguy10]

Late adopters here as well. 5 Sr's on ours.

[Bruceb]

some sr's and some VIC 888s and 884's

We have 9 SRXs on our bot this year. No complaints yet except our software team commented on some wonky embeded PID loop software, but they got it working.

All nine are on CAN. We crimped PWM cable headers to each end, one male and one female so that the chain has a single direction that can't be messed up. A small ziptie where the middle wire is missing keeps em together.

We also have sensor input directly into three of them (limits and an analog absolute encoder). Using a few free 10pin cables from Samtec we just made some custom adapters depending on what the sensor is. All in all, we're very happy.

I don't think that's a fair characterization.

The PIDF in the SRX is meticulously documented in the SRX Software Reference Manual, and many teams have commented on how well it works. CTRE's chief software engineer Omar Zrien monitors these forums and stands ready to personally help any team having problems.

By wonky, I mean it didn't work the first time they tried it. 30 mins of actually reading the documentation fixed the problem. No complaints since it works well now.

We have 11 SR's on robot + 10 SR's + 1 Victor on practice.
We have obtained 5 SRX's but have not had time to explore them - and until then will stay with SR's. (yeah late adopters)

Intrigued by SRX's expanded functionality (CAN, local PID) - but not a priority at this point - Happy with SR's performance.
I suspect next year we will be using SRX's, maybe even later this year(?)

Talons sr for us

[Optimism]

We currently have 12 Talon Srx's on our robot, 8 of them for just swerve motors.

[Tammyo]

This year we are using six Talon SRX’s on our robot to have the ability to use CAN and to give our electronics a neater appearance.

[jimbo493]

We are using 7 SRXs and 2 New Victors, personally I love them in every way except the wire is permanently attached, I would love it it it they could be disconnected/replaced. I also love how much easier the CAN network is to use that the Jags.

Now if you are comparing Talon SRXs to Jag...

They are not apples to apples, that's the point. This is our first year using CAN. I think the experience is going really well for us. The PIDs are great and the limit switch features are great too. The regular ones are just not as nice compared to the new ones.

With the new Talon SRXs, you can make a CNC machine with limit switches and servo control! It's great!

I do wish the pinout was bigger... anyways, I know our team had a great experience with them (so far, that is)

6 SRX, all PID.
1 SR

[MaGiC_PiKaChU]

14 SRX, 12 of them in PID control

[JDGallagher]

14 of the SRX

By these, do you mean CAN programming the set points, and on-talon PID controlling the actual output voltage?

If so (just curious) do you ever retrieve the position onto the 'RIO to make a true closed loop, or do you just use this as a "super-sized servo"?
