Yup.. i fried an SRAM chip a few weeks ago.. the XMOS chip has survived i think..Heater wrote:mynameisdev,
Forgot to say, be careful when using a single port as input and output alternately else something might get damaged.
For example when using LEDs and switches on a 4 bit port, normally the thing is in output mode driving the LEDs. That means it might be fighting against switches that are providing a short circuit to ground or Vcc when pressed. Not good.
Same applies to driving a port as output to any other device that may be outputting at the same time.
Perhaps a few resistors on the port pins is all it takes keep currents under control and make it safe.
New to XMOS and XCore? Get started here.
