Homebrew FX Chrony display
- Thread starter DaystateRebel
- Start date
Solved... Sorry to have bothered you.
I re-downloaded the code and now it works... do not ask me why
But the joules displayed are wrong.
I've added:
{"HADES", "JSB", 15.89, 0.22, 1.03, 5.5},
{"JUMBO HEAVY", "JSB", 18.13, 0.22, 1.175, 5.5}
and this is the results. 71.37 joules, must be 7.1
may be the line 431 should say divide by 1000 and not 100?

Y, sorry, I screwed that up. Repo updated. You are right, line 432Solved... Sorry to have bothered you.

energy = 0.5 * (my_pellets[pellet_index].pellet_weight_grams / 100) * powf(fspeed, 2);
Should be
energy = 0.5 * (my_pellets[pellet_index].pellet_weight_grams / 1000) * powf(fspeed, 2);

I got my Arduino environment all set up. I have compiled and verified that all code samples given thus far will work. all looks good. now to decide on what display to use. I also 3d designed a replacement fx chrono battery door and now need to find a power pack that will stay on to run the chrony from a larger battery source. not sure if I used the proper tie in points on the chrony and that is what is causing my pack to shutoff. I used the power and ground pins on the side of the board. I see others have tied into the battery terminals for external power supply and that may be why.

How does it shut down? The battery terminals on the side of the PCB work. You have to supply 5V though and not 4.2V (lipo) because there is a voltage regulator. Also, the FX Chrono times out and shuts itself down after 3 mins if not connected.

@Hallyster61's minimalist magnet mount
Works great!
Vey nice low-profile. Snap-on...snap-off

I have an 8000 mah 29.6 wh charger pack. using usb-a 5v/2.4 amp port. I get a steady 5+ volts output at a full 100 percent charge. I power up the chrony no problems. hook to phone app on android. sits there a few minutes 2 or less then it shuts off. it seems the power pack isn't seeing enough current draw possibly and shuts itself off. power pack does have a button on the side to wake it up/ turn it on. if i hit button to try and turn chrony back on it takes 2 presses. first wakes up power pack second turns on chrony. may need a different pack. when batteries are reinstalled chrony acts as it should and stays on no issues.
DaystateRebel,
the last code update you posted will not compile. it breaks around line 174.

this is my error code. compiling with heltech wifi kit 32 board

The FX Chrono does not fully power up until connected to the app. I think it draws about 10mA until then, which should still be enough. Maybe your suspicions are correct and that pack has some sort of a current draw sensing circuit. Did you try to connect it directly to the battery terminals, like you mentioned?

<sigh> No idea how that snuck in, repo fixed. Line 77 should read
#define SENSITIVITY_MAX 100

It's not currently supported, we can only work on hardware we have samples of. There's no guarantee when or if it will be supported

Then I guess I'll have to just muck along.
I'm not a total Newbe at programming so this is a pretty new toy to play with.
It is open source so I guess I'll start down this trail and see where it leads.
You'd be amazed at some of the stuff I've programmed for.

Install the libraries (Only do this the first time) Click Sketch | Include Library | Manage Libraries ... Use the "Filter your Search" to search for and install
1) u8g2
2) OneButton

Now using Windows 7? I have to go other ways to install things as the latest Arduino don't run on my System.
I've found other ways to install the needed Libraries.
I use the install Zip method.
