Touchscreen graphical data monitor, debugger and Logger for CAN protocol based on an ARM-microprocessor which designed for an autonomous middle size robot.
- Display live data in the CAN protocol attached to the system in a 128*64 graphical LCD
- Store the information received for later review on the MMC memory card
- Touch control with an easy interface for manual settings of circuits or related systems
- Using the ARM Microprocessor that makes processing faster
- Monitor several messages via RGB Leds
Multi-task monitoring and logger system programmed by Keil uVision with C programming language. In the driver section, I implemented and defined CAN protocol, Graphical LCD, SPI, Interrupts and memory card in this system. In the util section which includes all the details of the monitoring system, we have initialization, tab, logger, network, RGB Led and Main files.
- initialization.h: defined all driver files and pin configuration so every other file can use this library for accessing to whole system parameters.
- tab.h: contains commands that display the taskbar and get the touchscreen information.
- logger.h: to make a text file every minute and save data on the memory card and Information on the CAN bus is stored on it
- network.h: read or write on CAN bus, along with this activity, the RGB LED file displays these reading and writing functions via RGB Leds.
To build this device, firstly, Its electronic circuits designed in Altium Designer software. The circuit of this device consists of 3 different parts. It launched after assembling and taking various tests. A system consisting of two electronic circuits and a graphical LCD that put together.
Processor, touch screen control and display input circuits. This system reads the CAN bus data and displays information on the graphical LCD. All data are saved in an external memory to use when needed. Additionally, There is also a touch controller that the user can enter any manual command.
