getting my LEDs to work using rust on a raspberry pi (version 3 B v1.2)
There's a lot todo but things are moving along
currently it takes 4 command line arguments: -t: u64 - the time between updates in ms -b: u8 - the general brightness of the leds -l: usize - the number of leds (defaults to 15) -s : String - The light show it will produce settings are as follows
1 - trans - cycle through the trans colours 2 - trans2 - cycle through the trans colours which should look like the flag more 3 - breathe - Loop over all colours going around a hsv circle 4 - 5 - off - turns the leds off
Some little notes for me :
I'm using a very custom ws2818 driver, written by my friend, it actually cross compiles for my 32bit arm raspberry pi 1 b, which the old one I was using didn't so that's nice, means I can make pull requests to it if I need to add functionality and might suggest wider functionality anyway (in theory it should actually become no-std capable as well since it was advertised as such but just wasn't before)
I was using the color-art crate before, but after testing turns out that it doesn't work with arm cpu's or something, or cross compiling, anyway I moved the code that wasn't working out to a test script and it still didn't work, kinda weird might be worth looking into
Now I have to deal with the strip not seeming to work correctly. I don't know if it is spi doing something weird, currently the first ~10 LEDs flash odd colours and don't seem to always take commands, on top of that ALL the LEDs are the wrong colours and they are inconsistent as to what they change to (actually it seems to be almost on a loop, maybe this has something to do with clock cycles or the spi bufsize which I had to increase). This might be a problem with the led strip and some faulty connections. Although I'm worried it's two problems, the incorrect colours and the flashing across the first ~10 controllers (30 lights)
15 LEDs works fine which suggests that it is either a problem with sending 100 leds data, although if I make it think it has 100 leds it doesn't seem to have a problem which really seems to suggest it's the strip. this would suck
