ADIS16250: Help with setting up SPI

[InitialDriveGTR]

Hello all, I finally got it working. I fixed it by changing the settings for the SHIFTOUT and SHIFTIN commands. Here is my source:

<code>
DEFINE OSC 20
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_SPBRG 21 ' 57600 Bauds
DEFINE HSER_CLOERR 1
DEFINE SHIFT_PAUSEUS 1000

INCLUDE "modedefs.bas"

Hserout ["ACTIVE",13]

RST var portd.0
SCLK var portd.1
CS var portd.2
DIN var portd.3 'data from PIC to Gyro
DOUT var portd.4 'data from gyro to PIC

temp1 var word
index var word

high RST

pause 1000

main:
low CS
Shiftout DOUT, SCLK, 5, [$04\8,$00\8]
high cs
pause 10
low CS
SHIFTIN DIN, SCLK, 6, [temp1\16]
high cs

HSEROUT ["Temp1: 0x",dec temp1,13]
pause 100
goto main
</code>

Good job!!

I wrote up some new code that is meant to use two ADIS16250 Gyros. Once I figure out what LSB (Not Least signifigant bit)(I think), I will use them in a RC Helicopter Navigation system.

I hope this helps anyone that has had any trouble with these gyros too. Thanks for all your help!

Look fine but there's 2 mistake in this

     DEFINE HSER_CLOERR 1

should be

     DEFINE HSER_CLROERR 1

__________________________________________________

   INCLUDE "modedefs.bas"

Nowhere in your code you're using MSBPRE, LSBPRE or else, you're using the SHIFTIN/SHIFTOUT mode # instead. You can remove this INCLUDE line.
__________________________________________________

Just for safety sake, you should set CS0, CS1 to high before the main loop. Just before the PAUSE 1000

The Defines for the Hardware serial were generated using a program I found here. So, I honestly didn't even know what it was(or at least I didn't put much thought into them). As for the MSBPRE, etc. I found I fould change between using the numeric values and the text versions, so I just left it there.

DOH! so it was partially my fault. You used the old version of the SPBRG calc... wich is mine... i thought i sent the updated one seems not. BTW.. you're not using HSERIN so it doesn't cause any problem

Anyways here's the corrected version

EDIT: i remind to have posted an update... but on a USB thread. DOH!

Anyways, there's another applet comming soons including Timer calc, Reverse timer calc, SPBRG and HPWM. Still on test as now.

I don't want to do the same mistake twice

Do you know what the "LSB" is on the ADIS16250 datasheet? I think it is being used as a unit. Thanks

PS mister_e, I could host your calculator software on my website if you would like
