The DM300027是一个低成本 16位 28引脚新手开发电路板 an easy to use工具that allows you to start 开发 with dsPIC30F/dsPIC33F和PIC24设备. The 16位 28引脚新手开发电路板 is supplied with a preloaded设备that demonstrates the following电路板 功能ality Interrupt handling using timer1 to toggle the LEDs, UART 功能ality using the on电路板 USB to echo characters sent from a PC terminal programmed with a 9600 baud rate. The 开发电路板 has the option of being powered by a 9V DC power supply or by the USB bus. The position of jumper JP1 determines which power source is used. Connect jumper pins 1和2 用于the 9V power supply or jumper pins 2和3 用于the USB. In addition, jumper JP2 selects either 5V or 3.3V power source 用于the targeted设备. The dsPIC30F/dsPIC33F和PIC24设备use an on电路板 PIC18和USB 接口用于UART 通讯.
