I'm not currently working on an updated firmware version, although it is in my future plans. You're welcome to add them yourself (it's all open source), as it is pretty straight forward.
Hi, I'm new at this board. I have 2 UBW32's right here and i want to program it a a mplab c program... to use XBee, serial ports, AD, PWM, SPI, all stuff, floating point math, kalman, pid, trigonometry, read GPS, PWM, and so on... the question: to program this chip i have to delete the firmware (it comes with version 1.0, now is 1.4.3) it already comes with? (my application: an UAV system inside a rc helicopter) thx 4 ur orientation, and/or tell me a link.
Yup, you need to replace the firmware that's on the UBW32s with your own. You can use the built-in HID Bootloader to do that. Start with some of the example projects on the UBW32 website (HelloWorld or HelloUSBWorld), then modify them to do what you want.
I think I used 330 ohm resistors between +5 and each I/O pin. However, I was using very old LEDs that probably needed the 10mA that this would allow through the LED.
There are many newer LEDs that max out at 2mA, or 5mA. For those, you'll need larger resistors.
What you want to do is read the max current and voltage drop from the LED's datatsheet. If you are hooking up to 5V, then subtract the voltage drop from 5V. Then divide that by the desired current to find the resistance you need.
The green LED that is always on is on pin RB5, which is VBUSON. Any time the USB port is active, this is an output and can not be controlled by hardware. It is designed to control the 5V USB power rail when used as a host USB controller. I wish that we could control it in software, but as it is, it's kind of useless to us (unless you're in host mode).
hi brian, when do you think firmware with commands for AD PWM usart etc will be available? i can't wait more to play with with that! :)

I just bought a circuit like this, im gnna program it into a PLC which is remote controled via a TCP server :)

What size resistors are you using off of your 5V and GND? I wanted to try this to test my headers, but don't want to burn out any LEDs... Thanks!

AHHHH! RB5 !
That pin is driving me crazy! Did you know how to disable the VBUSON Function?
