To set up the hardware, wire all external devices devices to the DE1-SoC as specified. Then, on an Android phone, turn on data and enable a WiFi hotspot. Enter the hotspot's SSID and password at the top of the function esp8266_init1(...) in esp8266.c. Finally, as usual, open Eclipse from Quartus, program the DE1-SoC's FPGA, build the embedded_software project, and run it as Nios II hardware.
The following hardware modules are connected to the DE1-SoC via its GPIO ports:
- 4x4 membrane keypad
- SG90 9g Micro Servo
- Terasic RFS Daughtercard
4x4 membrane keypad's connections to the DE1-SoC (DE1-SoC JP1 port pin: keypad connection):
- GPIO_0[10]: R1
- GPIO_0[12]: R2
- GPIO_0[14]: R3
- GPIO_0[16]: R4
- GPIO_0[18]: C1
- GPIO_0[20]: C2
- GPIO_0[22]: C3
- GPIO_0[24]: C4
SG90 9g Micro Servo's connections to the DE1-SoC:
- GPIO_0[8]: 5v (red wire)
- GPIO_0[9]: GND (brown wire)
- GPIO_0[7]: PWM (orange wire)
Terasic RFS Daughtercard's connection to the DE1-SoC:
- Plug into JP2 GPIO expansion header of DE1-SoC.
