⑼System Reset Circuit The RESET pin on the AVR is active LOW, and setting the pin LOW externally will thus result in a reset of the AVR. The RESET has two purposes: 1. To release all lines by tri-stating all pins (except XTAL pins), initialize all I/O registers and set program counter to zero. 2. To enter programming mode (for some parts also the PEN line is used to enter programming mode). Furthermore it is possible to enter high-voltage/parallel programming mode by drawing the RESET pin “very” high, where very high means 11.5 – 12.5V.

⑿DS1302 Module The DS1302 Trickle Charge Timekeeping Chip contains a real time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with less than 31 days, including corrections for leap year. The clock operates in either the 24–hour or 12–hour format with an AM/PM indicator. Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: (1) RST (Reset), (2) I/O (Data line), and (3) SCLK (Serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1 microwatt.

9


The DS1302 is the successor to the DS1202. In addition to the basic timekeeping functions of the DS1202, the DS1302 has the additional features of dual power pins for primary and back–up power supplies, programmable trickle charger for VCC1, and seven additional bytes of scratchpad memory.

Note: For detailed information of DS1302’s use, please refer to the datasheet named “DS1302.pdf ” included in the Product CD Rom. ⒀DS18B20 Module The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source. Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.

How to install and use(works with the AVRICC software): Step1.connects to PC via RS232 port (note it will not work with USB-RS232 converters!),the JP3 jumper keeps connecting. Step2.Power on the board via USB cable or external 6-12V power supply.

11. Frequently Asked Questions 1).I tries to power the board, but the board does not power up, what’s wrong? Make sure that the POWER LED has turned on. If the LED is not on, check to see that the external power supply(DC6-12V) or the USB power is properly connected, check to see that the J1 is properly connected .It is necessary to note that the external power supply(DC6-12V) and the USB power can not be connected simultaneously. 2) How is power supplied to the experimenter’s board? Three supply options exist: USB power Cables, external 6—12VDC and programmer/debugger power supplies are supported. You are only allowed to choose one of them. 3) What devices can be programmed with the experimenter’s board? AVR mega16/32 Starter Development Board is designed to develop applications using the Mega16/32. The device can be replaced by Mega16L/32L/16A/16A/ 8535 device derivatives, respectively. 4) The Mega16/32 is no longer accessible via programmer/debugger, is something wrong with the device? - Verify that the target device is powered properly. - If the target is powered locally, verify your programmer/debugger is connected properly. - If the programmer/debugger is connected properly, the Mega16/32 is possibly "dead". Well, it's not really dead, it's just that it can't be reprogrammed until the Mega16/32 is unlocked (for detailed method of unlocking an AVR device, please search for solution on the internet). 5) I have loaded the Mega16/32 sample code, but It doesn’t seem to be working, what’s wrong? -Try to disconnect the SI-Programmer cable or JP3，in case of some IOs occupied. - Make sure the relational jumper is correctly connected. - If the relational jumper is correctly connected, pls check whether the FUSE BITS had been changed. Note: For detailed information of FUSE BITS settings, please refer to the datasheet named “mega16.pdf ” or “mega32.pdf ” which is included in the Product CD Rom. 6) I have loaded the Mega16/32 sample code, but It seem to be working very slowly, what’s wrong? Make sure the system clock had been changed .The AVR mega16/32 Starter Development Board has a default system--internal RC 8MHz system clock, and the sample codes in product CD-ROM is based on this default system clock. If the system clock had been changed to lower one like 1MHz, the board will work slowly.
