This program uses 10 The data book shows 38 bytes as a maximum for the 10 MHz clock rate see data book B 1 5 when the configuration and application checksums are used his size may be increased if the receiving node buffers sizes are known Depending on receiving node clock rate and amount of RAM dedicated to buffers increasing the number of data bytes placed in a packet can drastically increase the time to program a Neuron Chip 3 The only time ack service is used is loading the application All other cases unack service is used For a possible noisy environment this may want to be changed to unack This program would really speed up if unack is used Currently there is a timer load_image that is used to know when to set up the next packet This program could be changed so that the ack is waited for Other possible additions a Check if the node to be programmed has its read write bit set b Maximum number of times to resend a messag MOTOROLA LonWorks TECHNOLOGY AN1251 AL 413 y If the version number on the node to be programmed is the same as what is expected For example do not program a version 2 3120 with a version 3 exported file d Program configuration data If configuration data is programmed program it first In addition make sure your NEI file is program with the new configuration information The reason the configuration is programmed first is because the NEI file co
