Weather Final Project

Current DE2-115 Quartus build synced to the active working project.

This repo now matches the live FPGA_Final file set instead of the older raw-sensor baseline.

Current build status

• Quartus revision: FPGA_Final
• Top-level entity: FPGA_Final_Project_Weather
• Board: DE2-115 / Cyclone IV E
• Clock constraint: CLOCK_50 at 50 MHz

Included project files

• FPGA_Final.qpf
• FPGA_Final.qsf
• FPGA_Final.sdc
• DE2_115_pin_assignments (1).csv
• src/FPGA_Final_Project_Weather.vhd
• src/weather_station_top.vhd
• src/esp_uart_sensor_bridge.vhd
• src/vga_dashboard.vhd
• src/weather_icons_pkg.vhd
• src/uart_rx.vhd
• src/uart_tx.vhd
• src/status_logic.vhd
• src/hex7seg.vhd
• src/debug_uart_telemetry.vhd
• src/vga_timing_640x480.vhd

Active design

• Sensor data comes in over UART from the external ESP32-side bridge.
• src/weather_station_top.vhd is the current top implementation synced from the latest weather_station_top_vga_icons_compatible.vhd working file.
• src/esp_uart_sensor_bridge.vhd is the current parser synced from esp_uart_sensor_bridge_daynight.vhd.
• VGA uses the icon-enabled dashboard build.
• HEX displays show temperature, humidity, and pressure digits.
• LEDs indicate sensor validity/activity, host link activity, and parser activity.

UART input path

• FPGA UART input uses GPIO[7].
• The bridge parser expects lines in this form:
  • WS,sht,bmp,sps,temp,humid,press,pm25,daynight
• Example shape:
  • WS,1,1,1,235,520,1013,085,1

Notes on repo normalization

The live Quartus working folder referenced several files as ../... from outside the project directory. In this repo they have been normalized into tracked repo paths:

• weather_station_top_vga_icons_compatible.vhd → src/weather_station_top.vhd
• esp_uart_sensor_bridge_daynight.vhd → src/esp_uart_sensor_bridge.vhd
• vga_dashboard.vhd → src/vga_dashboard.vhd
• weather_icons_pkg.vhd → src/weather_icons_pkg.vhd
• DE2_115_pin_assignments (1).csv is tracked at repo root

Removed from the old baseline

These older files were dropped because they are not part of the active Quartus build anymore:

• src/bmp280_stub.vhd
• src/i2c_byte_master.vhd
• src/sensor_hub.vhd
• src/sht45_stub.vhd
• src/sps30_uart_stub.vhd
• src/weather_station_top_esp_uart.vhd
• src/patch_time.py
