Can run off a single solar cell. o Source up to 30 mA with internal diode, 50 mA with external diode. 2 Monthly Meeting of the Seattle Robotics Society on January 15, 2011 o Best Practices o Develop hardware layer first o Implement timing critical functions in hardware, complex functions in software o Use provided APIs and macros – allows for: . Component upgrade automatically . Easy conversion between PSoC3 and PSoC5 with minimal changes o Reserve and use “debug pins” to access internal signals o Keep digital and analog signals separate – processor die split, orient this with board layout o Use dedicated pins for internal op-amps o Watch for hardware race conditions – clocks are different! o Read and know the errata sheets o Reserve time for experimentation Resources o www.cypress.com o www.psocdeveloper.com o www.cypress.com/training Conclusion Mingling Pictures from the meeting... 3 Monthly Meeting of the Seattle Robotics Society on January 15, 2011 4 Monthly Meeting of the Seattle Robotics Society on January 15, 2011 5 Monthly Meeting of the Seattle Robotics Society on January 15, 2011 This file is archived on Yahoo Groups under “SeattleRobotics” in the “Files” area.

LEGO Dimensions Quick! Memorize all these numbers. There will be a quiz later. http://en.wikipedia.org/wiki/File:Lego_dimensions.svg Math is Hard! LDU = LDraw Unit A 1x1 stud brick or plate is 5/16” or 8mm (0.8cm) The height is 6/16” or 9.6mm (0.96cm) To make the math easier, LDraw designers came up with the LDraw Unit (LDU) Everything is a nice, easy integer this way! LDU studs bricks plates cm inch pt LDU 1 1/20 1/24 1/8 0.04 1/64 9/8 studs 20 1 5/6 5/2 0.8 5/16 45/2 bricks 24 6/5 1 3 0.96 6/16 27 plates 8 2/5 1/3 1 0.32 2/16 9 cm 25 1.25 1.04 3.125 1 0.39 28.3 inch 64 3.2 8/3 8 2.54 1 72 pt 8/9 2/45 1/27 1/9 0.0353 1/72 1 https://www.lugnet.com/~330/FAQ/Build/dimensions LEGO Bricks Are Not Square Bricks are 8mm wide by 9.6mm high How do you make widths and heights match? LDU makes the math easy.... How many plates = how many studs? 2 studs = 2x20 = 40 LDU 5 plates = 5x8 = 40 LDU 6:5 Brick Ratio How many bricks = how many studs? 6 studs = 6x20 = 120 LDU 5 bricks = 5x24 = 120 LDU Even Numbers of Studs Any even number of studs corresponds to a combination of bricks and plates, since 2 studs = 5 plates 4 studs = 6 studs = 3 1/3 bricks = 5 bricks = 80 LDU 120 LDU (or 10 plates) (or 15 plates) 2 studs = 1 2/3 bricks = 40 LDU (or 5 plates) Odd Numbers of Studs Since 1 stud = 2½ plates, no combination of plates adds up to exactly one stud 1 stud = 20 LDU 2 plates = 16 LDU ?? = 4 LDU (Missing ½ plate!) 3 studs = 60 LDU 2 stud = 40 LDU 1 brick + 4 plates = 56 LDU 5 plates = 40 LDU ?? = 4 LDU (OK) (Missing ½ plate!) But where do you get ½ plate? One answer: brackets.
