3 | 5 | Redmine Admin | Usecases: |
4 | * sensor for 4 sensors |
||
5 | |||
6 | 1 | Redmine Admin | use dg409 to switch between sensors. (DG409 is 2:4 with 2 address lines, DG408 would be 1:8 with 3 address lines) |
7 | 6 | Redmine Admin | Dann kann ground gleich mit geschaltet werden und mehrere sensoren sllten sich nicht beeinflussen. |
8 | 5 | Redmine Admin | * 2x 5v output for pumps. |
9 | * i2c RTC for date (standalone). |
||
10 | * CAN for candis. |
||
11 | 1 | Redmine Admin | 1xPWM output (trivial canio, workaround fuer lampen. Warum 2?) |
12 | 7 | Redmine Admin | 1xPWM output buzzer; 17:[[https://www.homofaciens.de/technics-base-circuits-h-bridge_ge.htm]] muesst sein, mit not baustein. |
13 | 1 | Redmine Admin | Wenn invertiertes PWM-Signal vorhanden ist, spart man sich nen enable. NOT + NAND |
14 | 5 | Redmine Admin | * Update via USB is a nice feature. Circuit already available. |
15 | * RTC for switching lamps, standalone |
||
16 | * PWM output for lamps |
||
17 | * loud buzzer for alarm/alarm-clock |
||
18 | * button for confirm stuff |
||
19 | * OUT output for lamps; 2x3V (plant lamp/room lamp) |
||
20 | * 2LEDs regular |
||
21 | 1 | Redmine Admin | * SPI NAND-Flash |
22 | 6 | Redmine Admin | * Switch connection VUSB to can |

25 | 1 | Redmine Admin | Most things can be copied from candis. |

||
36 | * 2x 2Pin Out pumps (5V, high current, with mosfets) |
||
37 | |||
38 | h1. HMI |
||
39 | |||

||
43 | * 1 Button, quit alarm |
||
44 | * 2 Button boot/reset (firmware update via USB) |
