PWM for dc motor and servo motor using ez430-rf2500

Abhishek Madhyastha

Other Parts Discussed in Thread: CC2500, SIMPLICITI

I'm using the ez430-rf2500 to remotely control the speed of a small DC motor via PWM and a small servo motor. 4 switches are provided for the transmitter target board of which 2 switches controlling the DC motor increase and decrease the speed using PWM technique while the other 2 for the servo, shift it from one extreme position to another.
I know how to program the msp430 and can control both the motors if they are connected to one of the boards. But what I want is to connect the 2 motors to the receiver board & control them from switches connected to the transmitter board based on the interrupts generated.
The problem is, I don't know how to interact with the cc2500 on the ez430-rf2500. I'm not able to find any proper references or sample programs to learn about the same. It would be very helpful if someone could give me some simple programs or a programming tutorial to understand this.

Hi Abhishek,

Are you trying to communicate wirelessly between two boards (2 eZ430-RF2500 boards?) The board comes with the Sensor Monitor Demo software that uses the SimpliciTI stack for the wireless communication - the software for this demo is included here: http://www.ti.com/lit/zip/slac139 and it is described in the user's guide for the eZ430-RF2500 www.ti.com/lit/pdf/slau227.

If you are looking for more help with using SimpliciTI communication, I would recommend searching and posting in the SimpliciTI forum here: http://e2e.ti.com/support/low_power_rf/f/156.aspx

This post also includes links to some resources on learning and using SimpliciTI: http://e2e.ti.com/support/low_power_rf/f/156/t/303370.aspx

Regards,

Katie

I'm facing similar problem, so i was searching and found some tutorials how to start simple wireless communication, hope theese tutorials will help you :)

http://glitovsky.com/blog/?page_id=21 It is engineers personal webpage, he is consulting people about MSP430 family and wrote tutorial on ez430-rf2500

http://cnx.org/content/col10684/1.10/ - this is lab works from Berkley university which explains everything step by step in a pretty simple way. This helped me a lot in understanding how wireless communication works :)
