I have solved that problem....actually I removed the voltage divider and used transistor with collector directly connected to CS of BMA180 as it is internally pulled up....
I am facing another problem now......
I have successfully read acceleration data registers of all three axis but I can't...
I have a problem with chip select(CS) pin of BMA180....Initially I set CS high, SCK high, and MOSI high....Then I start reading chip ID and it returns 03h which is ok but after sometime the voltage on CS pin drops to 1V and data is corrupted....I have used voltage divider of (560 ohms and 1k) on...
when you are using software serial i.e other than the hardware serial there is no interrupt so you can use kbhit to check if there is an incoming data at the soft serial other wise you can poll and wait for the receive....
and for GPS receiving you should search in the forum there are several...
first you can define serial streams like this..
#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7,stream = hardware) // Hardware serial
#use rs232(baud=9600, xmit=PIN_C0,rcv=PIN_C1,stream = software) // Software serial
then you can receive the software serial as
data = fgetc(software)...
CCS compiler allows you to define any digital IO as your software serial....
so you can use one hardware serial and one software serial just look at the CCS help..
We have multiple meters installed on different locations, if that would have been the problem then it should be appearing in all meters but we are facing this trouble in some specific areas where the environment seems to be very noisy in electrical terms....
Now we are thinking to remove the...
yes you use matlab to send data to zilog, then the zilog will drive the motor...
because in serial communication you need to receive and process the data can't directly drive the motor from serial port...
i haven't worked on zilog..
if you use db-9 it means it is serial RS-232 so just search how to communicate with serial in zilog...
once you receive the data from serial into zilog then you can drive stepper motor with it...
also you have to learn how to send data to serial port using matlab for...
LPT port is the parallel port in your computer DB-25 connector for further please search it on google trust me it works.....!!
you can use any microcontroller....!!
yes but I have done it using LPT port...
for serial port I have done it with micocontroller, in which I send the data using serial and the controller receive the data and then drive the motor....
Thanks for the reply guys...
our steady state current is below 0.1 A so i don't thinks thats the problem....
can you give a diagram to depict the topology...
the current topology we are using is..
Hi
We are working on a metering project in which we take 3 phase AC input..
we have used LVM2P-015R10431 protection device...
http://www.konkurel.ru/raychem/2Pro/LVM2P.pdf
the protection is working fine the circuits remains safe when surge comes in but it doesn't reset automatically until done...
i agree with FVM you shouldn't blame Ohm's law..
if your adapter have actual ratings 5v/1A then even at 1A the voltage would have been stable at 5V (almost)...
it will follow the Ohms law when you operate it within its actual (not written) power range...
