5 | 26 | Maximilian Seesslen | Warum alles zusammen? |
6 | RTC aktiviert MCU via Batterien. Muss LED-Traffo aktivieren. Können unterschiedliche Traffos fur unterschiedliche Lampen-Typen (kalt/warm) sein. |
||
7 | |||
8 | 8 | Maximilian Seesslen | h2. New Features compared to Mainswitch/CANSwitch |
9 | 1 | Maximilian Seesslen | |
10 | * More current |
||
11 | * Fix Wakeup |
||
12 | 6 | Maximilian Seesslen | ** Beim Mainswitch gab der Power-button einen Stromimpuls auf den ACQxxx und auf einen GPIO. Wenn das system von extern gespest wurde und die MCU schlafen war, konnte sie nicht wieder aufgewekt werden. |
13 | 1 | Maximilian Seesslen | * Periodic wakeups to make measurements: RTC |
14 | 31 | Maximilian Seesslen | ** RTC_OUT gibt spannung auf den ENABLE des MAX5200 |
15 | 33 | Maximilian Seesslen | * Programmed wakeup for plant lights and light-buzzer |
16 | 1 | Maximilian Seesslen | * Diode ? Voltage-Drop issue |
17 | ** Ideal diode with Mosfet |
||
18 | * High voltage (24V) ? |
||
19 | 33 | Maximilian Seesslen | ** TS78L05CX-RFG |
20 | 1 | Maximilian Seesslen | ** Different connectors |
21 | * Global Timeserver; It already has batteries |
||
22 | * Real touch keys |
||
23 | 18 | Maximilian Seesslen | ** Why? In addition to increase illumination. But thats what candis was for. |
24 | 1 | Maximilian Seesslen | * Over-Temperature power off (PCB/Box) |
25 | * Buzzer? |
||
26 | ** indicate peridoc on/off during day time |
||
27 | 8 | Maximilian Seesslen | * External Solid State Relais for high power switching like Horo |
28 | 1 | Maximilian Seesslen | |
29 | * 4 Sectionen: SZ, WZ, MEMS, ? |
||
30 | 33 | Maximilian Seesslen | ** Switching sounds valid. But not sure. |
31 | ** Stoeren ungepowerte Platinen CAN? Sollten sie nicht. |
||
32 | 1 | Maximilian Seesslen | ** Erzwingt Sternkonstelation |

77 | 28 | Maximilian Seesslen | h2. Regulator boards |
78 | 1 | Maximilian Seesslen | |
79 | 28 | Maximilian Seesslen | h3. Number of LED drivers |
80 | |||
81 | 1 | Maximilian Seesslen | Living room has 4 lamps, maybe 6 later. |
82 | 28 | Maximilian Seesslen | |
83 | h3. Electrical design |
||
84 | 1 | Maximilian Seesslen | |
85 | 29 | Maximilian Seesslen | Optokopler needs 10mA, 1.38V_F. |
86 | 28 | Maximilian Seesslen | Powermeter needs common ground anyways to measure voltage. |

||
88 | 10 | Maximilian Seesslen | |
89 | 32 | Maximilian Seesslen | h3. Regulators |
90 | |||
91 | LDB350 hat 9 ~ 36VDC EIngang und 2-40V Ausgang. |
||
92 | |||
93 | 1 | Maximilian Seesslen | h2. Issues |
94 | |||
95 | h3. Wie Straenge schalten |
||
96 | |||
97 | * 4 x LTC4412 umstaendlich, E.g. status ruecklesen |
||
98 | * Jeweils 2 Mosfets notwendig um zu isolieren, klein + gross |
||
99 | 16 | Maximilian Seesslen | * Wozu Stränge? 2 direkt verbundene Buchsen reichen nicht? Auch nur um sich allenfalls Verteiler zu sparen. |
100 | |||
101 | h3. USB interface? |
||
102 | |||
103 | * Usable with Raspberry or so. |
||
104 | |||
105 | 13 | Maximilian Seesslen | h3. Light optional |
106 | |||
107 | * Media does not need light. The name is "helios". Use CANSwitch then. |
||
108 | 15 | Maximilian Seesslen | * But having the regulators in batteries is nice. They work even without MCU board. |
109 | |||
110 | * 4xPWM |
||
111 | * 2xTerminals; IN+OUT |
||
112 | 1 | Maximilian Seesslen | * Switch can be done on helios, only for first block |
113 | 17 | Maximilian Seesslen | ** If the switch is also on the blocks, Single power supply can be used |
114 | 20 | Maximilian Seesslen | ** Do i really have multiple power supplys for different LEDs? Could be, an active one for High power and an small one for nice ambience. |
115 | 24 | Maximilian Seesslen | ** Smaller power supply for bus only? |
116 | 1 | Maximilian Seesslen | * Must not connect Grounds of different power supplys |
117 | 17 | Maximilian Seesslen | |
118 | Das mit IDC oder aehnlichem zu machen klingt nice. Dann gehen theoretisch 4x4 (4xNetzteile schalten), man braucht 'nur' 4xPWM, Kaskadierung. |
||
119 | 25 | Maximilian Seesslen | Alternativ 'addresse' einstellbar. Dann ist man noch flexibler, e.g. |
120 | 17 | Maximilian Seesslen | 8 x kalt, 8 x warm. |
121 | 8 x Zimmer, 4 x Tisch. |
