Version 0.9.8. Added extra path to the fonts for Debian buster. Changed the PID to work on Proportional on Measurement. Added loops so that it looks like the PID is running at 100 mSec intervals.
| 335 | 1 | |
| 2 | 1. Introduction. | |
| 3 | ||
| 4 | 2. Hardware. | |
| 5 | ||
| 6 | 3. Raspberry GPIO. | |
| 7 | ||
| 8 | Most of the hardware is connected via the 8 GPIO pins on the 26p connector. | |
| 9 | Currently the pins are used or reserved for: | |
| 10 | ||
| 11 | GPIO0 - out - 433 MHz transmitter module (FS1000A). | |
| 12 | GPIO1 - out - reserved for PWM. | |
| 13 | GPIO2 - out - Frontpanel LED. | |
| 14 | GPIO3 - bus - DHT11 sensor. | |
| 15 | GPIO4 - in - Frontpanel Key Enter. | |
| 16 | GPIO5 - in - Frontpanel Key Down. | |
| 17 | GPIO6 - in - Frontpanel Key Up. | |
| 18 | GPIO7 - bus - 1-Wire bus (Maxim protocol). | |
| 19 | ||
| 20 | ||
| 21 | 4. Keyed menu. | |
| 22 | ||
| 23 | Using three buttons the device can be controlled. The menu is entered by | |
| 24 | pressing the Enter key for 2 seconds. With the up and down keys you can step | |
| 25 | through the menu. Press escape to go back, Press enter for 2 seconds to | |
| 26 | set the new value. | |
| 27 | Escape is press both arrow keys together. | |
| 28 | If not in a menu, short touch of the keys activate the LCD display backlight. | |
| 29 | The arrow keys select the current item to display. | |

139 | * Start with pGain, dGain and iGain set to 0. |
| 335 | 140 | * Increase Kp until small oscillation. |
| 141 | * Increase Kd until a little damping. | |
| 142 | * Increase Ki after Kp and Kd are set until longterm convergence. | |
