Change: Hive Interface 0.3
Contents
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.
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.
Currently:
| 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 Clockk (RTC) will plug in.
- Remove +5 VDC from Pin 1.
- Move ground on C?.
This will allow the DS3231 to plug into header H2 without modifying the Hive Interface board.
Currently:
| H2 I2C Bus ver 0.3 | |
|---|---|
| Pin | Signal |
| 1 | +5 |
| 2 | +3.3 |
| 3 | I2C |
| 4 | I2C |
| 5 | Ground |
New (but remove + 5 and make Pin 5 NC:
| Old H2 I2C Bus | New H2 for RTC | |
|---|---|---|
| Pin | Signal | New Pin |
| 1 | +5 | No connect |
| 2 | +3.3 | Pin 1 of H2 |
| 3 | I2C | Pin 2 of H2 |
| 4 | I2C | Pin 3 of H2 |
| 5 | Ground | No connect |
| Ground for C | Ground | Pin 5 of H2 |
| H2 I2C Bus ver 0.5 | |
|---|---|
| Pin | Signal |
| 1 | +3.3 |
| 2 | I2C |
| 3 | I2C |
| 4 | NC |
| 5 | Ground |
