As per the f1611 datasheet (rtfm), at 2.2V, the max is 1.5mA per pin and 12mA max over all ports at 3.0V, the max is 6.0mA per pin and 48mA max over all ports
Thus, pal is using the devices outside of specified operating conditions. It is recommended that you use a transistor to switch larger currents. -Joe On 2/17/07, Philip Levis <[EMAIL PROTECTED]> wrote:

I was trying to drive some EL-wire, which requires 120mA; unfortunately, the node wasn't able to drive that.
