PSoC กับ FM Radio Receiver Module (RDA5807SS)

PSoC Config

1. Global

CPU clk 3 MHz

2. Pinout

Port_0_0 - Port_0_5 Pull down

3. LCD

• • module LCD

  • LCD Port Port_2

  • BarGraph Enable

4. I2C

• • module I2CHW

  • Read_Buffer_type Ram Only

  • CPU_Clk_speed 6MHz OR LESS

  • I2C Clock 100K standard

  • I2C Pin P[1]5 - P[1]7

ทดลอง 1 กำหนดให้ GPIO1 GPIO2 GPIO3 เป็น 1 ที่ละบิต และสุดท้ายเป็น 1 พร้อมกัน
