Hi Wajid,

You need IR sensors to detect the incoming and out going cars. To store data of car no. & driver details you need to interface flash memory or EEPROM to the controller. Post your further quries.

thank you for replying Amrith and AJISH ALFRED. yes Amrith i want to interface flash memory with microcontroller because drivers details and cars no are require high memory space and eeprom have small memory space as 2k bits only. but i need help for interface it. i interface only lcd with 8051 yet and now iam interfacing keypad for entering the details. Actually i want to interface such a memory space when the car exit then the details which driver gives when entering the car compare it and tell about all details that gives the driver when leaving the car are correct then he will exit the car. and message sent to the controller of the parking office no that this car will leave the parking stand

 No i haven’t complete the hardware yet but some what complete. yes i am using ir sensor for sensing it

Hi wajid,

Good Job !!!

From  hardware point of view, flash memory are available in different memory sizes and has different interfaces to connect it to micro controller. Generally some Flash memory have SPI interface, others have I2C interface & some have parallel interface. So, i suggest you to choose the right memory depending on the interface you have on the controller.Also, select the size of memory  based on the maximum number of number of entries you want to save in flash memory.

From software or firmware point of view, you need to study the procedures on how to read & right data on flash memory. Further quries kindly post.

All the Best!!!
