Pls help me to start with code in Basic for gyro L3G4200D
For example a test read-out program
Thanks

hello, please i need help on how to decode the quadrature signals from mechanical mouse for direction, using pic16f887 or 18f4520.
i will appreciate any solution in mikroC ,links and schematics or just an advice on how to go about it thanks

Hi everyone, I'd like to receive and basic mikrobasic code, just to read the AN0 of PIC16F876A and set PWM1 in the scale.
Thanks.

hi i have a program to measurement the period of my rc receiver , total period and , how long the hi puls stay high.
here my code : im use easypic 5 , cristal 4mhz , pic16f877a , microkbasic V5.01
i have also a another program but its works , and thats it , not safe thats why i thy this .
[code]
Program puls_meting_1
' Procedure for high-going pulse:
' 1. Configure CCP to capture on rising edge
' 2. Setup Timer1 so it will not overflow during max pulse width time
' 3. Enable ccp capture
' 4. Once capture flag bit is set, save captured value as T1
' 5. Reconfigure CCP to capture on falling edge
' 6. On 2nd capture, save 2nd value as PW
' 7. Subtract T1 from PW for the pulse width value
'DEFINE OSC 4
Symbol Capture = PIR1.2 ' CCP1 capture flag

Dim PULS2 as WORD ' totaal tijdt

i request every body which person use micro c \ basic.pl shear hear code sample which can drive adc controlled relay \ led etc bit vise.
RA0_bit= 1 or 0
RC2_bit= 1 or 0
RB5_bit= 1 or 0
RD3_bit= 1 or 0
ETC
