The connectors of the Knitting Machine have a pin distance of 2.50 mm (respectively 2.0mm for some newer models). This includes the evaluation of the sensor signals and how the solenoids are set into the correct position at the right time.
#ARDUINO UNO R3 DEBUGGING SHIELD KIT MANUAL#
The implementation of the firmware follows the information found in the service manual of the KH-910. Therefore, the solenoids are controlled using two 8 bit I2C port expanders.įinally, the shield allows you to connect a beeper which will tell you acoustically about the current state of the machine and when you are allowed to proceed knitting.įor debug purposes, three LEDs (Power On, Debug 1 and Debug 2) are also located on the shield. As there are 16 solenoids to control, an Arduino UNO would not provide a sufficient amount of output pins for this purpose. The other part controls the actors of the knitting machine, the solenoids. One of the Needle Count signals is attached to an Interrupt-capable pin of the Arduino to be able to process the information about the new position of the carriage in time. This is done directly by connecting the sensor signals to Arduino input pins. The Arduino has to read the Hall Sensors, the Needle Count signals and the Belt Shift signal. Other Versionsīasically, the Arduino shield provides the connectors to interconnect the Knitting Machine with the Arduino. The manufacturing data for the connector can be found here. It is possible to build a replica of this connector using a piece of acrylic and 2.00mm^2 solid copper wire.
AYAB Shield Solder Instructions english/ germanįor all models except KH-900 and KH-965, Brother used a proprietary power connector.The main difference to the 1.3TH are the additional 2.0mm Connectors for KH-900 and CK-35 This shield version works only with Arduino UNO.ĪYAB Firmware v0.8 or greater is required for this shield version.
