KernelPanic

Too complicated for an Arduino. It will run on a Windows machine. I really like your Arduino controller idea though.

Shame it doesn't have a demo mode that simulates shots. I guess we'll have to wait until people start reviewing it to see what it can do.

I am working on a program that will import the velocities into an SQL data base, then match them against a reloading and firearm database. This is going to take a Loooooooooooong time.

They were shamed into doing it!. It's probably a microcontroller based system to supply the temperature and altitude readings. That means that we cant use the new software with our generic hardware like before. It would expect some sort of an identifying string from the microcontroller before it would work.

Glad you got your unit up and running, elchupacabra. I just got mine finished a couple of days ago. Heres some pix. Front view: Side View: Bottom View. The plug is epoxied in so it just plugs in the side of the chrono and the velcro holds it in place. Inside view. The packing foam that holds the battery in place is removed for visibility. It works just fine with CE's software, but I keep getting timeouts with the android app. Not surprising since I know squat about smart phones.

Make sure the 10k resistor is between the TXD (tip) and GND (sleeve) coming from the ProChrono side (on the BT2S side it would be between the RXD and GND). Take a look at the Wired Connections troubleshooting section at the end of the guide in the first post. I put some steps in there that may be helpful given what you've described. If you're still having trouble after that, I would get in touch with Virtuabotix tech support. They were solid gold when I was building and troubleshooting the prototype. It's definitely a V1.06 issue. I cant seem to post the link, but I read an article that explains why I had to add the pull up resistor to get the ProChrono to receive using the V1.06 board. I contacted Virtuabotix and they are aware of the problem, but they offered to send me a prototype level shifter for $5 plus shipping. Not a happy camper about that! It seems these units don't work correctly at either 5V or 3.3V. I don't mind adding a couple of resistors, but I can't figure out the correct value for the ProChrono tip. 10K does not work. It might not event be a matter of simply a pull down resistor with this new revision.

The BT2S hates me! Here's what I've done so far: Using a solderless breadboard and a 5 volt power supply, I connected the ProChrono to a MAX232 TTL to RS232 chip. Both the ProChrono software and a terminal program work fine. I then set the BT2S to 1200 baud. I crossed RX and TX for a loopback and the terminal set to 1200 baud echoed the characters back correctly. I connected the BT2S to the ProChrono, connected the 10K pull down resistor to ground and nada with both the ProChrono software and the terminal. Now here's the strange part. Using the terminal, it would not perform a change string operation, but if I connected a 1K resistor from the BT2S TX terminal to +5V the change string command would work. Still no joy on any output from the ProChrono. It would seem to be a level issue. I am using V1.06 of the module(I tested two of them), but I have noticed that any examples I have seen are using V1.05. I wonder if they messed the levels up on the new revision? Any ideas would be much appreciated.

It doesn't go full screen. It goes bigger if you press the big screen button, but notice that the maximize gadget is grayed out in both cases.

I'm using a homemade interface with Windows 8.1 and am having no problems so you shouldn't with CE's interface. The Bluetooth I am building is another story..
