Hi all,

I'm reading in data from 2 sensors:

1. IR sensor using A/D conversion
2. SONAR sensor using software RS232

If I disconnect the IR sensor, the SONAR sensor is read flawlessly. Howeve ...

Yes, I have the MX045HS 10MHz oscillator.

Hi all,

I'm designing a PCB with 2 PICs on it. I was wondering if I can save space by using just one oscillator (i.e. feeding the output of the oscillator into both PICs CLK pin)?

Thanks,

Yep, that was it! Used the INVERT option and it worked perfectly! Thanks Sherpadog and PCM.

What signals are you referring to? Are you suggesting that my Tx and Rx lines are reversed? If so, this is not correct or I wouldn't be seeing any data coming in.

Hi all,

I am using the MaxSonar EZ-1 ultrasonic sensor. It outputs data in RS232 format. According to the 2nd page of the datasheet (see below), the RS232 voltages range from 0-5V and not -12V to ...

I found this post on the Microchip web site for generating PWM signals. Can anyone tell me how this could be written to compile with CCS?

Thanks in advance,

Finally got it working!! Just wanted to thank everyone for all of their input. The solution was based off of Ttelmah's code, but with a modification based on ckielstra's code (actually, the "is ...

Mark,

I'm not sure how to check for transmission errors? Can you please explain?

Thanks,

Ttelmah (or anyone),

I ran your code and by itself, it works perfectly! However, capturing this data from the sensor is a very small portion of my code. I have a ton of other things going on (e.g ...

Hi all,

I have an ultrasonic sensor that outputs RS232 data in the following format:

Rxyz and then a carriage return

where xyz is a 3 digit number that represents distance. I'm using a globa ...

Yeah, that worked - thanks PCM!

Hi all,

I have 2 IR sensors which output an analog signal corresponding to distance. I'm feeding the output from sensor #1 into AN0 and the output from sensor #2 to AN1. I'm trying to read each v ...

Hi all,

I'm trying to figure out what is more efficient. I'm attempting many operations with a 4 component vector (quaternions for those who are familiar). I'm trying to figure out if it's more e ...
