SHAH DISHANT H.Participant
Hi,
By changing the crystal frequency, the execution speed will vary.
If you are using peripherals on UART, it will nt work as BAUDRATE will be changed. For making it working, you have to change value of MULVAL and DIVVAL of ARM7 accordingly.
All the best.
SHAH DISHANT H.ParticipantHi,
Is this project accomplished ?
If not, let me know. I have implemeted the exact one before few days. My sytem is calculating the voltage, current, power factor and power factor and displaying it on LCD as well as Hyperterminal. On 1st day of each month, it will send total power consumed to the particlular mobile number.
SHAH DISHANT H.ParticipantHi,
This is really an apprecriable work.
You have accomplished almost all basic things. You can add functionalities like extending breadboard if circuit is more complex.
Really an awesome work my friend.
SHAH DISHANT H.ParticipantHi,
You can do one thing. See what data RFID reader is transmitting on Hyperterminal. If its receiving data properly on Hyperterminal, the issue is with LPC 2148 side. Make sure you have properly configured BAUDRATE of LPC2148.
It will be nice if you can post snapshot of data received on Hyperterminal.
All the best.
SHAH DISHANT H.ParticipantHi,
Ya 89V51RD2 has inhuilt bootloader to fetch new program from serial port and save in memory.
SHAH DISHANT H.ParticipantHi,
8051 has single UART port. GSM and HYPERTERMINAL needs UART. Can you please tell me how you have configured both on single UART?
After that only, we can say something.
SHAH DISHANT H.ParticipantHi Shilav,
Don’t worry. Nothing is wrong with the module. Its designed to go in power down mode if it has been kept on idle mode for a long time.
You can do one thing. When the LED is off, check power supply output with multimeter. You can fing LM117 IC in this module. Check input as well as output of LM117.
Check it out and post the output values here.
SHAH DISHANT H.ParticipantI would suggest following things.
1. Use RFID reader in train and tags at station to identify the station.
2. IR sensors to detect when train arrives at station (Smart use of RFID also can do the same). IR sensors can be used to sense that whether there are any vehicles or not.
3. Stepper motors to control the gate opening and closing.
All the best.
SHAH DISHANT H.ParticipantIf you eed to control firing angle of TRIAC, you have 2 options.
1. 555 as rectangle wave generator
2. Use Timer for generating rectangle waves with variable duty cycle
SHAH DISHANT H.ParticipantHi,
I have done the same using ARM9+LINUX. May I know which controller you are planning to use?
SHAH DISHANT H.ParticipantHi,
RFID ca be interfaced with 8051 using serial communication. You can connect it as easily as you connect with Hyperterminal.
If you want any help, let us know further.
All the best.
SHAH DISHANT H.ParticipantHi,
Can you post the codeplease?
SHAH DISHANT H.ParticipantHi,
I would like to comment one thing that why you are using PIC? Is it only for touchscreen? If so, you can use ADC with 8051 and touchscreen can be interfaced.
If you want program, I can help you how to do that.
First create buffer of 22 bytes in 8051 and stored data on that. Refer mazidi book for serial programming.
SHAH DISHANT H.ParticipantHi,
You can use ADC0809 for this purpose. It has 8 channelsand you can select the channel by 3 control pins (000=channel0, 001=channel1 etc.)
Once go through the datasheet and try. Its very simple.
All the best.
SHAH DISHANT H.ParticipantHi,
The above answer is true. Another option is to write pogram in Keil Software and save file with .asm or .a51 extensions. Build the file and it will generate .hex file. You can transfer that file to controller depending upon your controller.
All the best.
