6.1 Programming a Sequence to the Chip

To program a blinking sequence to the chip one to three on- and off sequences must be selected with the

slide bars. On time can vary between 1 ms to 255 ms with 1 ms steps and off time can vary between 10

ms to 2550 ms with 10 ms step. Sequences must be selected in numerical order e.g. you must first select

on- and off time 1 (sequence 1) in order to be able to use on- and off time 2 (sequence 2). Also both on-

and off times must be selected for each used sequences. The preview window shows the currently

selected sequences. To program this sequence to the chip push the Train button. During the programming

the LED will blink as selected. After programming the Trained window should indicate Yes and the Run

and Run once buttons should be available. Also Manual button should be unavailable. Figure 5 shows the

evaluation software with two sequences programmed to the chip.

To run the trained sequence push the Run or Run once button. Pushing the Run once button runs the

programmed sequence once and then puts the chip back to standby mode. Pushing Run button puts the

chip to continuous run mode. To put the chip back to standby mode push the Run button again. To reset

the chip and to remove the trained sequence from chip push Reset button. After reset the chip is on its

initial state and the LED follows the Manual button.
