1st, i woul like to ask ya which one of the following two microcontrollers do ya think is the best and that i should buy along with Dev. board for it?a) www.futurlec.com/ET-ARM_Stamp.shtml (LPC2119 Micorocontroller)This is the Dev board for it: http://www.futurlec.com/ET-ARM_Stamp_Board.shtmlb) www.embeddedartists.com/products/boards/lpc2106.php (Philips ARM7TDMI LPC2106 microcontroller;LPC2106 QuickStart Board ).This is the quick start Dev board for it: http://www.embeddedartists.com/products/boards/prototype.php
I want to avoid obstacles not just with infrared and ultronsonic range sonars but also with vision. That's why i want to use a better ucontroller.
the LPC2129 has some a/d channels which are useful for some sensors (e.g. compass, temperature, accelerometer, etc). the LPC2106 has no a/d - this hasn't been an issue, though occasionally it would be nice to have it
the hb-25 motor controll is connected to a ucontroller and controlled just like a servo. So i want need to worry about how many pwm and how many are left. right? i mean i think on the basic stamp2 i just connect the motor controllers to 4 pins 12,13,14,and 15 thats it (one for signal is the one that connects to ucontroller and than the other 2 or ground and voltage. i m thinking that connecting 4 motor controllers want be a problem right.
you dont want to use a pwm channel if those motors are controlled like a servo . . . servos are pulse width dependent, but motors also care about how often you send that pulse. if your hb-25 motor can be controlled like a servo, you want to use a D/O pin . . . otherwise use a PWM pin (hope that didnt confuse you!)
The ARM7 PWM channels can be configured to drive servos.
Admin, you said i need a laptop to do good vision avoidance, but if i get the UMCcam2 or 3 along with the ARM7, want i be able to do object avoidance and navigation. Maybe not mapping and recognition, but avoidanace with the roborealm software right.
O and last but not least, is it possible to connect more than one ARM7 together and how is that possible?
What do you mean by basic vision?
