Thank you sir for your opinion.
Can you suggest me filter and protection circuit which should be used in electronic circuits for the Industrial environment. Thats huge help. :)
First of all thanks sir for your time and reply. :)
As you said in your reply. Yes the controller updates the LCD display every second or more than 5 seconds. I just little confuse that should i use extra supply for the micro-controller separately .? or any circuit which will totally isolate...
Hello ,
I'm Working on Industrial Project based on PIC18F series micro-controller. I'm using TQFP packaging pic18f97j60 controller. In this project i used some modules such as PWM for AC motor control . LCD , 4x4 Keypad , I2C for external EEPROM , L297-L298 and TIP122 for relays & Solenoids of...
Hello everyone.
I'm making a project in which i want to store the 8 bit data in external eeprom 24LC512 with pic18f85j11 in case of power failure. I already used the power capacitor ( 4700 uf) for providing the sufficient time for store the data. To save the data at power failure time, i used...
@fvM : first of all thank you sir for your time and reply. Sir I'm making an application in which motor turns either forward or backward as the motor finished its task it remain stops and the shaft has been locked. It holds the one position by blocking the rotor shaft.
For that purpose I turn...
Hello everyone.!
I'm making stepper motor control project with L297 and two L298 for stepper motor rated 2Amp capacity.These are parameter for L297
Reset pin 20 = 1 (+5V)
Pin 16 Osc = recommended circuit used as per datasheet
Pin 15 Vref = 0.36 V
Pin 11 Control = 1
Pin 10 Enable = 1
Current...

Sir i just want to rotate the motor for two or three steps only. Is this acceleration and deceleration ramps are necessary .? can you tell me what is the value for the ramps i have to select for it..?
the wiring is seems too be alright even i can posted the schematic if you want to see...
@ Klaus St
Sir , Im giving clock around 1khz from pic microcontroller which is connected with opto then opto is with 74hct and further L297
It is a Bi -polar motor i changed the polarity but problem stills.
:(

Sir , Im running the motor in full mode by giving...
Hello Sir..
I am Using L297 and L298 Stepper Drive with Bi-polar Stepper Drive.
I just gave the 1 to the direction pin but the motor changes its direction unconditionally. Some time it goes clockwise direction and sometime it goes anticlockwise direction. I just feeling helpless nothing comes in...
Okkk okk
1 thing i have to ask is that any way to check L298..???
Beacause all hardware structure is okay working fine. but the only problem is that motor just changed its direction from clockwise to anti-clockwise what ever its control..
So far I'll drive motor without load..
Thanks :)
hello
am using l297-l298 stepper drive to rotate the bipolar stepper motor along with PIC18f85j11 micro-controller. It gives problem that whenever i set up a direction for rotation, it gives malfunctioning as in result. sometime the motor rotated in clockwise or in anticlockwise.
but in some...
