Programming Editor can not find hardware

[wk_james98]

Hi ,

I am using 18X controller. After i assembled my simple circuit board for 18 X controller on breadboard . I start to write a test program and download into 18X ,but i tried 20 times only 2 times the program can download in to 18X . The rest of times it show "Error - hardware not found" i have check all connection , and circuit all are correct . I have no idea any more . I used 4.5 voltage supply to 18X. Is the voltage must be 5 V ?? Please help. Thanks

Sometimes this happens if your PICAXE program has a command which makes it unavailable for a time - e.g. 'sleep'... when this is the case you can turn the power off, start the download and turn the power on when download starts - the reset caused by power off will allow the download - or use hard reset on the chip... othersiw check all joints etc.. good luck!
