LB1001

 Top  Previous  Next

The LB1001 is a standard LED board supplied with IB100x interface boards. The LEDs on the board are arranged into 4 groups, each group consisting of one green and one red LED. Although the LB1001 connects to IB100x boards, the actual control of the LEDs is effected from the EM1000 module installed on the NB10x0 board. To turn a certain LED on, set the corresponding general-purpose I/O (GPIO) line LOW. The line has to be configured as output. I/O line control is described in detail in the documentation for the "I/O" (io.) object found inside the "TIDE and Tibbo BASIC Manual". These LED's can also be used to play patterns generated by the ("pattern") .pat object. Correct "mapping" is required for this to work -- see object documentation for details.

Table below shows LED arrangement for this board. LED numbers correspond to the numbers shown on the mechanical drawing for the LB1001.

Note 1. This resistor's value is 0 because there is another resistor connected in series with the EM1000's GPIO line and located on the NB10x0 board.
