- Add Chip Select to SPI (GPIO 10 SPI0_CE0) to H7. This is for the AD7124-8 Eval Board. Currently:
| H7 SPI ver 0.3 | |
|---|---|
| Pin | Signal |
| 1 | +3.3 |
| 2 | SPI0 11 SPI0 CLK |
| 3 | GPIO 13 SPI0 MISO |
| 4 | GPIO 12 SPI0 MOSI |
| 5 | Ground |
- Change pins on H2 I2C so RTC will plug in. Remove +5 VDC from Pin 1. Move ground on C?. See http://hivetool.org/w/index.php?title=Real_Time_Clock_RTC
Currently:
| H2 I2C Bus | |
|---|---|
| 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 |
