| + | The Multi-Demo firmware is pre-programmed onto the Datalogger Board, so out of the box, the behavior of the board will match the description in this section. This firmware may always be re-programmed onto the board using [[# | ||
| + | |||
| + | To use the MultiDemo firmware: | ||
| + | - On power-up, the board behaves as a motion switch: the entire display lights up when the board is moved. When the board is still for a few seconds, most icons turn off and only the logos, power and battery icons remain on. Initial power up state: {{ : | ||

| Note that tilt measurement is, in general, a slow measurement. This is because at any given moment, the motion of your hand, for example, could be producing acceleration that would interfere with the tilt measurement. If we average the total acceleration measurement over time, we can get rid of the transient, or AC, effects, such as those due to your hand moving, and we are left only with long-term, or DC, effects -- in this case, gravity. So for best results, tilt slowly and wait for the display to refresh. | Note that tilt measurement is, in general, a slow measurement.

| + | ===== Write your own software ===== | ||
| + | Talking to the development board can be done using your own program with the following commands: | ||
| + | |||
| + | Baud rate: 153600 8N1 | ||
| + | |||
| + | Commands: | ||
| + | 0xAA - Enable PC control, the board should respond (500+ ms) 0x55 and Eink display will show " | ||
| + | |||
| + | 0xB1 to start collecting data | ||
| + | Start collection can be augmented with additional commands which specify different modes | ||
| + | |||
| + | 0xB1 0x0L 0x00 0xGS 0xN2 | ||
| + | Where L is the length: 1 for 8-bit; 0 for 12-bit | ||
| + | G is the maximum G: 1 - 2G; 5 - 4G; 9 - 8G | ||
| + | S is the sampling rate: 0-12.5hz; | ||
| + | N is the filtering: 0-Normal; 1-Low Noise; 2-Ultra low noise | ||
| + | | ||
| + | EG: 0xB1 0x00 0x00 0x15 0x02 would be start, 12-bit samples, 2G max, 400hz sampling, normal noise mode. | ||
| + | | ||
| + | 0xB2 to end collecting data | ||
| + | |||
| + | |||
| + | Data is transmitted 16-bits for each direction, 2's compliment, little-endian, | ||
| + | The first block of data will be 8-bytes and can be discarded. | ||
