Re: Lowest Latency method for real time data?

It could be your overflowing the buffer depending on how much data your trying to send. I think i will get it up and running with PySerial over USB and then play with UDP and TCIP. I've written the code (pretty simple with hundreds of examples about) getting them working reliably is the hard bit whe...

Re: Lowest Latency method for real time data?

yeah thought about it using pyserial over usb which i suppose is closest to using a zigbee radio or something similar. But i tend to code on my laptop downstairs while the pi lives upstairs (I use Adafruits webIDE). I guess i'm being stubborn when i can't get something to work properly i have to fig...

Lowest Latency method for real time data?

Hi, Over the last few months i've been learning how to program using python and am working on a program using accelerometers and gyros. I now have the devices outputting meaning full data to a log file which i can then plot in excel. This is an inefficient method and i need to view the data live (wh...

Re: ADXL345 Accelerometer

Hi all, How do i remove the SR02 from the above code? I've just started learning to program in c (very hard) and all the mods i make result in a compile error. Everything else is setup and i can see the device on the bus and have read data from another device using some adafruit python code so i kno...

Re: Do you want a cheap screen?

Ah that explains it my Girlfriend was bought a subscription last Christmas so it arrived by post. Does anyone know of any links to people hacking them? I've googled and other than people replacing the video's not much seems to have been done. I'd like to figure out if i can get the Pi talking to it.

Re: Serial Connection 3V3 0r 5V

Thanks for the reply. I think i will try the 3v3 then to keep things a simple as possible if i have a bit of overhead I'm a little happier. It seems the simplest thing to do.

Serial Connection 3V3 0r 5V

Hi all, First post so please go easy i'm no expert on this stuff and the last time i did any electronics was 10 years ago! I have just taken delivery of a serial GPS unit (MediaTek MT3329) now this draws max. 48mA but does drop down to 37mA after lock. I understand the 3v3 exposed on the GPIO header...
