Arduino-Pedelec-Controller

Software for the Pedelec/E-Bike controller based on Arduino hardware, see www.pedelecforum.de "ForumsController"

Board Pinout / Connections

http://www.pedelecforum.de/wiki/doku.php?id=elektrotechnik:forumscontroller

Arduino Pinout (for breadboard test)

in config.h check HARDWARE_REV 21 All options are left to default values, else you have to change the connections

A14: Voltage read-Pin

Leave it open, it will read some random values...

38: FET: Pull high to switch off

Add an LED with Resistor (~470Ω) to GND

A15: Current read-Pin

Leave it open, it will read some random values...

11: Buzzer

Connect buzzer with resistor (~200Ω) to GND

37: Switch

Connect a push switch to GND

12: Switch 2

Connect a push switch to GND

Nokia 5510 Display (PCD8544)

Connect Display pin -> To arduino Pin The Display only supports 3.3V, use a level shifter for I/O Pins!

LED+  -> 3.3V
VCC   -> 3.3V
GND   -> GND

sclk  ->  7 [PH4] (clock)
sdin  -> 17 [PH0] (data-in)
dc    -> 16 [PH1] (data select)
reset ->  6 [PH3]
sce   ->  8 [PH5] (enable)**

SCE is connected to PH2, but PH2 is not connected on the Arduino, so change the line

unsigned char sce   = 2);  /* enable      (display pin 5) */

to

unsigned char sce   = 5);  /* enable      (display pin 5) */
