© Generalplus Technology Inc. Proprietary & Confidential 3 JAN. 06, 2009 Version: 1.1 Easy-to-use SOUNDPLUS 1. GENERAL DESCRIPTION The easy-to-use SOUNDPLUS II (GPESII) is an enhanced version of easy-to-use SOUNDPLUS (GPES). Many features have been added in GPES II to increase its capability and performance. One of the most significant features in GPES II is that no complex program structure is necessary. With only nine instructions and six registers, GPES II is capable of driving sophisticated tasks and playing realistic sound with simple program structure. Programmer can easily implement application rapidly and increase productivity efficiently. The GPES240B2, one of the GPES II families, stores up to 40 seconds of sound data (@ 6.0KHz sample rate). It also contains four trigger pins, eight output pins, PWM audio output, and five LED flash alternations. To assure the system reliability, a watchdog and a Low Voltage Reset (LVR) are also built in for monitoring possible critical conditions. With the high cost/performance ratio, GPES240B2 is one of the most suitable engines in the industry for vocal products. 2.

Instruction Sets Nine instructions involve LD, JP, LSR, ADD, SUB, AND, ORR, EOR, and END. “LD” represents LOAD and “JP” indicates JUMP. “LSR” shifts a register’s value one bit to the right. “ADD” and “SUB” are addition and subtract ion. “AND”, “ORR” and “EOR” are logical operations which indica te AND, OR and, Exclusive OR respectively. “END” ends program and enters into sleep mode for power saving purpose. 5.2. I/O Description GPES II has the following I/O pins: TG1, TG2, TG3, TG4, STOP [0:7]. The TG1, TG2, TG3 and TG4 are input pins and STOP [0:7] are output pins; moreover, STOP [6:7] can be shared with LED drive pins. PIN Configuration TG1 Input TG2 Input TG3 Input TG4 Input STOP.0 Output STOP.1 Output STOP.2 Output STOP.3 Output STOP.4 Output STOP.5 Output STOP.6 Output (shared with LED2 pin) STOP.7 Output (shared with LED1 pin) 5.3. Program Structure Overview The following description is an overview of GPES II program structure. For more information about GPES II programming method, please refer to GPES II Programming Guide. 5.3.1. Definition area The beginning of a program is t he Definition Area that defines some declarations before Initialization such as IC body, variable, frequency, debounce time and low voltage reset option. 5.3.1.1. IC body The first element defined in a program is a GPES II body. Example: SPES240B ;select SPES240B EXT_CLK_4M Freq4 ;Set default speech ;sample frequency to 7.8K LVR_DISABLE ... POI: ... ... 5.3.1.2. Debounce A key debounce time can be defined in Definition Area. The range of debounce time is 5ms ~ 35ms. 5.3.1.3. Variable A variable can be defined by adding a “#define” in front of a variable. A variable can be the combination of numbers and characters, but not underscore. Variable Syntax: #define VariableName <Register | NUM> Example1: #define var R0 ;define var as R0 Example2: #define const 8 ;define const as 8 5.3.1.4. External clock Users can define one external clock out of the following selections in a program. This option must be defined in definition area. EXT_CLK_3M; (3.0MHz) EXT_CLK_4M; (4.0MHz) EXT_CLK_6M; (6.0MHz)
© Generalplus Technology Inc. Proprietary & Confidential 6 JAN. 06, 2009 Version: 1.1 5.3.1.5. Low voltage reset The Low Voltage Reset (LVR), prevents system running into malfunction state, will intend to reset all functions back to the initial states if power VDD drops too low. The LVR works the same as Power-on Reset; it can be enabled or disabled via programming and must be defined in the definition area. LVR_ENABLE; enable LVR_DISABLE; disable 5.3.1.6. Infrared Red (IR) Function Some IR parameters must be defined in Definition Area before using IR function. We will only introduce the commands here. For more details on how to use these commands in your program, please refer to GPES II Programming Guide. 5.3.2. Entry point (Label) The essence applied in GPES II is the ENTRY POINT. Each trigger pin is assigned an entry point. Instructions must be located in a new line under its entry point. Any instruction located with the same line as entry point will cause error when compiling. Users can also define a label (ID) for an entry point. A label can be the combinations of number and character, but not underscore. In addition, a label can not start with a number. Example SpeechLoop: Sound1+Sound2 JP SpeechLoop When a pin is triggered, the program jumps to its corresponding entry point and starts executing. The entry points are fixed values. For instance, ‘0’ is the entry point of TG1 when 1Æ0. ‘1’ is the entry point of TG2 when 1 Æ0. Users can either use Entry Point ID or Entry Point Abbreviator to express an entry point. A summary of entry point for each trigger pin is as follows: Entry Point Entry Point Abbreviator Status
32 POI Power on initialization
0 TG1F TG1 1 Æ0 (falling)
1 TG2F TG2 1 Æ0 (falling)
2 TG3F TG3 1 Æ0 (falling)
3 TG4F TG4 1 Æ0 (falling)
4 TG1R TG1 0 Æ1 (rising)
5 TG2R TG2 0 Æ1 (rising)
6 TG3R TG3 0 Æ1 (rising)
7 TG4R TG4 0 Æ1 (rising)
8 ~ 253 (except 32) User-Defined entry point or label User-Defined
254 Speech event User-Defined
255 Timer event User-Defined
