3 | Relatively big MCU; Standard periphery can be tested within a single bringup run. Protocol can be added to biwak/arena release. |
||
4 | 5 | Maximilian Seesslen | |
5 | Current use-case: |
||
6 | * I2C has an issue that some times the board has to wait at bootup quite long time till i2c eeprom is functional. |
||
7 | * SPI has an issue that some times the board has to wait at bootup quite long time till spi flash is functional. |
||
8 | * Code cleanup; does the code still work; e.g. Timers. Complete disfunctionality would not be seen some times. |
||
9 | * Want to develop something with nice debug output. Bootloader was a little bit nasty. |
||
10 | |||
11 | 1 | Maximilian Seesslen | No further use? |
12 | |||
13 | 2 | Maximilian Seesslen | * Alarm clock |
14 | * CANBuzzer |
||
15 | * Reference RTC clock |
||
16 | ** CANSwitches have PWM output but no RTC. For light switches this compination makes sense. CANDis could do this. At least in combination with buzzers nice. |

20 | 1 | Maximilian Seesslen | * CAN |
21 | * USB |
||
22 | * Uart |
||
23 | * SPI-Flash |
||
24 | 4 | Maximilian Seesslen | * I2C-EEPROM; 80Bytes + ?KB |
25 | 2 | Maximilian Seesslen | * I2C-Connector |
26 | 1 | Maximilian Seesslen | * Buzzer |
27 | * LEDs |
||
28 | * Small LCD? waste of pins? |
||
29 | 2 | Maximilian Seesslen | * RTC |
30 | 3 | Maximilian Seesslen | * PWM-LED; Golden Dragon? |
31 | 1 | Maximilian Seesslen | * ADC (fixed resistors; 1/4 VDD) |
32 | 3 | Maximilian Seesslen | * Button |

34 | PA11 - CAN1_RX USB_DM |
||
35 | PA12 - CAN1_TX USB_DP |
||
36 | 6 | Maximilian Seesslen | |
37 | PB8 - CAN1_RX |
||
38 | PB9 - CAN1_TX |
||
39 | 7 | Maximilian Seesslen | |
40 | 8 | Maximilian Seesslen | Power-Cut would be a killer feature. But without companion? |
41 | Einfach "nur" einen CAN-bus stromfrei schalten. |
||
42 | Einzelnes Target antwortet dann "Gut" oder "Schlecht" und Parameter. Normale Applikation kann weiter laufen mit kleiner Erweiterung. |
||
43 | Evtl. sogar einfacher als das total isolierte Geraet am PC. |
||
44 | UART umschaltbar, naja, eher verwirrend. Noch eher multiplexen. |
