I don't think that SIMCOM do not use SIRFIII in their products when they say in the specs they do use it.
As I've known, SIMCOM & WAVECOME is the only 2 companies produce GPRS modules. So, SIMCOM is a big one, anyway :)
FIFO Design Doubts
I am not sure about what you want to do with your own FIFO system, so if my reply do not fit your need, just pass it :).
If you want to read and write FIFO at different clock frequencies, just place read code and write code in 2 different sections that will be done at 2...
I usually use Gerber tool for process gerber files created from Orcad Layout (using Tearsdrop, save Gerber file as a lower version).
I can find it in Orcad 16.0 but when I try Cadence 16.2, I can't find Gerber Tool.
Do you know where it is? Or there is a replacement for it?
Would you please...
Re: How to read data from MMC using PIC microcontroller ???
Oh, I wonder that why you don't use 25LC512 or 1024 to do this? It will be much more easier. In my opinion, MMC Cards is useful when we can access data stored like a computer.
Anyway, I think you have got a reason to do like that...
surely you can :)
You need an GPS modem to do this. Usually, GPS modems will process GPS signal from satellites and send out the results using I2C or SPI interface.
You just need a microcontroller to process data and do anything you want.
Good luck with your final year :)
Re: good gps vehicle tracking
Ctrl + Z is charater which has ASCII key code is 0x1A (You just need to send byte 0x1A to RS232, like you send 0x0D = '\r' and 0x0A ='\n')
How to read data from MMC using PIC microcontroller ???
You can try Microchip's Libraries (MDD File System, included in Microchip Application Libraries). My friend have used this one and he can read/write/create/delete a .txt file or a directory in MMC card.
