28. sources of frustrating delays when looking for a problem They are easy to check and will make a monkey of you more times than not if you ignore them One of the great advantages of having an interactive language embedded in a processor is if communications can be established then program tools can be built to test operations If the RS 232 channel is not in use your application or 1f it can be optionally assigned to debugging talking to the board through the language will provide a wealth of debugging information The LED s can be wonderful windows to show operation This takes some planning in design of the program A clever user will make good use of these little light Even if the RS 232 channel is in use in your application and not available for debugging don t overlook the LED s as a way to follow program execution looking for problems The NMIN 0803 Mini is designed so no soldering to the board should be required and the practice of soldering to the board is not recommended Instead all signals are brought to connectors So the best trouble shooting technique would be to unplug the NMIN 0803 Mini and try to operate it separately with a known good serial cable on power supply If the original connections have been tested to assure no out of range voltages are present a second NMIN 0803 Mini can then be programmed and plugged into the circuit in question But don t be too anxious to take this step If the first NMIN 0803 Mini
