How to modify accelerometer code for propeller demo board and tV display?

Caleb · 2008-03-22 17:33

I have LIS3LV02DQ accelerometer and found that Jomo already generate code for this.
But, I noticed that My propell demo board has different pin#, and I don't have LED display. My propell demo board has pin0~P7, while JoMo used p10, 11, 12 in his code for Clk and SOD and CS.

Q1)Can I just modify the pin from 10, 11, 12 to saying 1, 2, 3, then revise the code accordingly?

Q2) I don't have LED and have TV terminal. Can someone show me how I can modify the code for TV terminal out instead of LED in the code?

Thanks,

Hi,
Ah ha! The final thing·was that the powerUp bit was not being set! By default this thing is powered down.
Here is my code that works.
deSilva cheers to you·again.· The Forum at it's best.
Much thanks!

Check the other thread....I posted a modified file for Hyper Terminal.
