MAXQ610 Evaluation Kit

Evaluates: MAXQ610

General Description

The MAXQ610 evaluation kit (EV kit) provides a proven

platform for conveniently evaluating the capabilities of the

MAXQ610 low-power, 16-bit, RISC microcontroller targeted

for battery-powered applications. The EV kit includes the

MAXQ610 EV kit board, which contains infrared (IR) trans-

mit and receive devices, two RS-232 serial channels, four

8-pin headers providing access to the processor’s I/O port

pins, a 5V power-supply input, and a bank of eight pushbut-

ton switches for user input. The EV kit also includes soft-

ware, USB-to-JTAG/1-Wire

Adapter, 10-pin JTAG inter-

face cable, serial cable, and a standard A-to-mini-B USB

cable for connecting to a personal computer. The EV kit

provides a complete, functional system ideal for developing

and debugging applications as well as evaluating the overall

capabilities of the MAXQ610 RISC processor.

MAXQ610 Evaluation Kit Evaluates: MAXQ610 Infrared (IR) Interface The MAXQ610 microcontroller provides a dedicated IR timer/counter module to simplify support for IR communication. The IR timer/counter implements two pins (IRTX and IRRX) for supporting IR transmit and receive, respectively. The IRTX output pin can be manipulated high or low using the IRTXOUT bit of the power control register (PWCN) when the IRTX function is not enabled.

MAXQ610 Evaluation Kit Evaluates: MAXQ610 General-Purpose LEDs The MAXQ610 EV kit board has four general-purpose LEDs labeled DS1, DS2, DS3, and DS4. Each anode is connected to the board’s VDD through a 100Ω resistor, and each cathode is connected to a processor port 3 pin through a jumper as specified in Table 3. By setting the related port pin as an output, each LED can be illuminated by setting the port pin output register bit (PO3.x) to a logic 0.

Evaluates: MAXQ610 Once the software has been installed, open the application and create a new project in the current workspace. Ensure that the MAXQ Tool chain is selected from the drop-down menu, and open a new C project with a generated main.c file (Figure 4). MAXQ610 Evaluation Kit To configure the project to run on the MAXQ610, select Options from the Project menu or press ALT+F7. Select MAXQ61x from the drop-down menu and ensure that CLIB is selected under the Library Configuration tab (Figure 5).

Evaluates: MAXQ610 Select the Debugger category and ensure that Driver is set to JTAG. Next, select the JTAG subcategory and enter in the appropriate COM port for your USB-toJTAG/1-Wire Adapter. This can be found by finding the Adapter under Window’s Device Manager (Figure 6). MAXQ610 Evaluation Kit The sample projects are included in the workspace maxq61xevkit.eww and can be viewed in the Workspace window.

Evaluates: MAXQ610 Debugging with IAR Open the gpio project from the Workspace menu and ensure that the project settings described above have been properly configured. To view the source code for the project, simply double click gpio.c. The file isr.c is not used in this project, but contains the interrupt callback functions for other projects included with the EV kit. To begin debugging the project, click the Debug button or MAXQ610 Evaluation Kit press Ctrl+D.

Evaluates: MAXQ610 The gpio example uses a timer on the MAXQ610 to blink four LEDs. The first four pins of Port 3 are wired to these LEDs, and can be manipulated by the software. By shifting the mask variable, the position of the high bit moves through the mask to the bit for each LED (Figure 6). The PD3 register controls the direction of the pins on Port 3. Setting these bits to one configures them for output and allows the voltage to be driven low to turn on the LED.

Evaluates: MAXQ610 MAX-IDE MAX-IDE is the primary IDE used to program the MAXQ610 using assembly code. The latest version of MAX-IDE can be obtained from the MAXQ Development Tools webpage at www.maximintegrated.com/MAXQ_tools. Once installed, open MAX-IDE and create a new project (Figure 12). Select MAXQ JTAG under the Device menu and open the Options menu. From this menu, enter the appropriate COM port for the USB-to-JTAG/1-Wire Adapter.

Evaluates: MAXQ610 MAXQ610 Evaluation Kit Debugging with MAX-IDE To start debugging, simply click the run button, and use the Debug toolbar to step through the program. Using MAX-IDE to debug an application is similar to using IAR. Open the gpio project in MAX-IDE and the corresponding source code should open with the project. This example is the same as the previous example, only it is written in MAXQ assembly instead of C.
