Is 20MHz selection available in LONBUILDER?
If the input clock for your Neuron Chip is 10MHz or less, you can use the LONBUILDER or NODEBUILDER software to build firmware images in the usual way. These tools do not directly support the 20MHz input clock option that is available with the 3120A20x and 3120FEx chips. In this case, you will need to use the NEI20MHZ.EXE utility program, available from Echelon’s web-site, to overcome this limitation. To build an application for a Neuron Chip running with 20MHz input clock, use your LONBUILDER or NODEBUILDER software to create the Neuron EEPROM Image file (.NEI file), then post-process that file with the NEI20MHZ utility. This updates the communications parameter record in the file. You can then download this modified .NEI file to a Neuron Programmer to program the devices before soldering them to your target hardware board.
