GPS/GPRS logistics protocol vehicle terminal source program based on NXP LPC2387+UCOS-II

Overview

Version V0.2

Completed and verified functions:
1.GPS receiving function

2.Self-detection function

3. Log in to the server function
4. Reconnect to the server function

Notes on modifications:

1. Modify GPS PARSER.

2. Add/modify self-test function (GSM, flash, GPS, SIM Card)

Function description: Add the modified self-test function to the InitSystem function, and use the light mode UART3

Output debug messages.

3.Flash increases delay 2ms

Functional description: To prevent GPIO from changing pin positions quickly.

4. Add Flash Write protect mechanism (semaphore)

Erase protect mechanism (semaphore)

Function description: In order to avoid unpredictable results caused by Erase and Write at the same time, so

An additional semaphore protection mechanism is added to prevent this phenomenon.

5. Add Flash Read protect mechanism (semaphore)

Function description: In order to avoid unexpected results caused by simultaneous Read at the same time, we added more

The semaphore's protection mechanism prevents this phenomenon.
