Hi,
I've searched and read through many threads, but have not found a problem exactly like mine.
When powered, my Mini Pro board flashes a red LED near the reset button, while a steady green LED stays on:
I'm using CP2102 USB converter to program Arduino Mini Pro. Wiring is as such:
CP2102 => Mini
GND => GND
5V => VCC
TXC => RXI
RXC => TXO
(GRN not connected)
(RST not connected)
I have also tried this wiring:
CP2102 => Mini
GND => GND
5V => VCC
TXC => TXO
RXC => RXI
(GRN not connected)
(RST not connected)
And this wiring also:
CP2102 => Mini
GND => GND
5V => VCC
TXC => RXI
RXC => TXO
GRN => RST
I cannot load a sketch. Keep getting message: "Problem uploading to board... ...programmer not responding"
Tried using Mac OSX 10.6.8 and Windows XP - same result.
Made sure ports are set correctly.
Tried pressing reset button before and during upload process.
Once I tried Serial Monitor tool - there was some activity, but now I cannot see any. Window is blank.
What does the flashing red LED indicate?
Thanks for any help!
