Need more RAM | BasicX | EmbeddedRelated.com

Discussion forum for the BasicX family of microcontroller chips.

I am making a robot with the BX-24 with a lot of multitasking. It also uses PWM. So almost all my RAM is used up and I not even near done yet. Is there a solution to this problem? I know Netmedia sell the ram sandwich but thats only of the bx-01. Is there anything like this for the BX-24 that I am not aware of? Thanks Nick

no, there is nothing like this for the bx-24. the rampack with the bx-01 uses up most of the i/o pins. I know I have one. what you can do is to offload the PWM off the bx chip. there are different ways to do this. one of them is to use an I2C PWM chip. they have set frequencies but the duity cycle is selectable. then all you do to change speed on a motor is to send an I2C command to change the cycle. if there is nothing to change there is no overhead for the prossesor at all. this will cure your problem. --- wrote: > I am making a robot with the BX-24 with a lot of multitasking.

The BX-24 is pin-compatible with the Basic Stamp 2, right ? Try this link (don't know if it's any good to you - I don't even have a BX !) http://www.high-techgarage.com/products/supermax.php Regards, Justin. -----Original Message----- From: [mailto:] Sent: 07 November 2001 21:47 To: Subject: [BasicX] Need more RAM I am making a robot with the BX-24 with a lot of multitasking.
