Readout - Seconds x 1 - 5F to 56 (0 - 9 DEC).

Readout - Seconds x 10 - 4F to 4A (0 - 5 DEC).

Readout - Minutes x 1 - 3F to 36 HEX (0 - 9 DEC).

Readout - Minutes x 10 - 2F to 26 HEX (0 - 9 DEC).

Readout - Place - 1E to 15 HEX (1 - 10 DEC).

Readout - Lane Number - 0E to 05 HEX (1 - 10 DEC).

Taking even a closer look, you can see how the HEX format comes into play. Taking a closer look at the ASCII table, there are 8 sets of 16 values between 0 DEC to 127 DEC (00 HEX to 7F HEX). See channel memory map Parsing Out the Value Second, the channel number is determined by shifting right by one, masking the 5 LSB’s and then XOR it. A FALSE or 0 LSB determines the following data set represents readout values. The Least Significant Bit, LSB, from the channel number byte, determines this.

Refer to ASCII Table Parsing Out the Channel Addressįirst, determine if the data represents readout values or format, i.e. The channel number is determined from the byte of data having a value greater than 127 DEC which is immediately followed by up to eight bytes of data having a value less than 128 DEC for the readouts to display. decimal/colon activation.įor the purpose of this project the second set is not needed and is ignored. The data for the readouts is preceded by a one byte of data representing the channel number of the module.Įach module will receive two sets of eight bytes of data with the first set representing the readout value to be displayed and the second set representing the format, i.e.

01Ĭommunications to the scoreboard is done serially at 9600 baud continuously having no delimiters, new line or carriage return the scoreboard doesn't respond back at all to the timing console. So, data in array - Lane Number array - Place. The position of the readouts correlates similar to that of an eight character array. Lane modules are configured, by displaying left to right Lane Number, Place, Minutes x 10, Minutes x 1, Seconds x 10, Seconds x 1, Seconds x. The modules are configured to represent either Lane, Event/Heat, Lengths/Record, Team Scores, Place and Time information. Typical Scoreboard Configuration ReferenceĬolorado Time Systems developed the protocol to drive a scoreboard composed of multiple module displays having up to eight(8) seven-segment readouts for each.
