Hardware » Bringup

h1. Eval

* Big LEDs to test outputs / Backlight-PWM

* Amplified Buzzer to test buzzer output directly on MCU

* PWM output to test buzzers; 3V; normal and amplified

* Test for CANBus-cables;

** MCU with 4 inputs

** 4 outputs to control which line to be tested to detect shortcuts

** 4 outputs for LEDs to indicate errornous wire

** How detect shortcuts

** Button to reset

* Durchgangsprüfer ( buzzer-out / Buzzer-in )

** Do i really need this? Dont want to setup an multimeter

** Does not cost much

** The signal is already there. It might be usefull to inspect the board

h2. Functions

* Measure power consumption of boards

* Measure functions of PCBs (PWM Buzzer, Backlight)

* Measure periphery (e.g. buzzers)

* Test CANBus wires

h2. Buchsen

* GND

* Durchgang

* PWM out

* PWM in to buzzer

* LED/BL in to big LED

* Strom-Mess-Durchgang mit Schiebeschater; e.g. 1101M2S3CGE2

* 2xJST-4; Kabeltest

** Auch ueber Stiftbuchse fuer Schoenes Gehaeuse, Acryl ala Ophio

Stiftleiste

* GND

* 3V

* 5V

* LED in 1

* LED in 2

* LED in 3

* LED in 4

* 2 Buzzers

* 1 Big LED

* Heardbeat

* User

* 1 Buzzer reset test

* 4 LEDs "open connection"

h2. MCU Pins

h2. No-MCU version

* 4-Pin JST Power fuer CCandis Versorgung; CANBus

* 2-Pin JST CAN outlet for PC adapter; CAN

* 2-Pin JST Power fuer Miniminutnik; 3V

* 3-Pinheader Power VOUT, 5V, 3V, GND

* USB; 5V in

* Spannungsregler 5V; L78M05; was habe ich von den LED-Reglern? 

* Spannungsregler 3V; UA78M33CDCYR 3V3; 0,5A;

* 2 Pin VIN; 8-24V

* 2 Pin VIN; 3V

* 2 Pin Measure

* Schieberegler Shortcut; 1101M2S3CGE2

* -Strom messung 5V/3V; Schieber; 1201M2S3CQE2-

* 2 * Power-LED; 5V, 3V

* 4 * LED-In; 3V

* Buzzer-Input

-Je nach Stellung des Spannungs-Schiebeschalter sind an den Spannungsausgaengen nur 5V oder nur 3V verfuegbar.-

Strom ueber GND der Ausgaenge messen. Kein Spannungs-Schiebeschalter.

Testbar:

** Buzzer-PWM-Ausgang

** 4*3V Ausgaenge

** Backlight-PWM (Weisse LED ueber Mosfet)

** CAN durchgeroutet an PEAK Adapter

** Stromverbrauch, auch im Off-Zustand

** Brownout ueber 3V Eingang; manuel runterregeln

Nicht testbar:

** Buzzer an sich; "bringup" ist kein Funktionsgenerator

** I2C Ausgang; There are enough sensors around; I2C Ausgang seh spezifisch (only CANIO & CANRec)

MCU benefits

** Kein Canpong integriert

** Kein Funktionsgenerator
