Increase hole size for blue 12 VDC power connector.

Increased from .038" to .042".

Change GPIO pin for LED from pin 7 (default 1-wire) to pin 11.

This means that dad7 (data acquisition daemon that flashes the LED and reads the rain gauge) won't flash the LED. Need dad8 version. Maybe set LED GPIO pins with command line options.

Add Chip Select to SPI (GPIO 10 SPI0_CE0) to H7.

This is for the AD7124-8 Eval Board. Need Chip Enable (CE) to frame the word.

Hive Interface 0.3

H7 SPI ver 0.3
Pin Signal
1 +3.3
2 GPIO 14 SPIO CLK
3 GPIO 13 SPIO MISO
4 GPIO 12 SPIO MOSI
5 Ground

New:

H7 SPI ver 0.5
Pin Signal
1 +3.3
2 GPIO 14 SPIO CLK
3 GPIO 13 SPIO MISO
4 GPIO 12 SPIO MOSI
5 GPIO 10 SPIO CE0
6 Ground

Change pins on H2 I2C so Real Time Clock (RTC) will plug in.

  • Remove +5 VDC from Pin 1.
  • Make Pin 4 No Connect (NC)

This will allow the DS3231 to plug into header H2 without modifying the Hive Interface board.

Hive Interface 0.3:

H2 I2C Bus ver 0.3
Pin Signal
1 +5
2 +3.3
3 I2C SDA
4 I2C SCL
5 Ground

New:

H2 I2C Bus ver 0.5
Pin Signal

2 I2C SCA
3 I2C SCL
4 NC
5 Ground
