| 1 Migration from wiringPi to PIGPIO. | |
| 2 ================================== | |
| 3 | |
| 4 WiringPi is unmaintained and replaced by pigpio. This will need large parts | |
| 5 of thermferm to be rewritten. It is also a good moment to replace the current | |
| 6 server protocol with json data and start sending data chaanges over | |
| 7 websockets. | |
| 8 | |
| 9 Some parts of the code can make use of direct kernel support, since kernel 4 | |
| 10 there are lots of new modules. Fact is that thermferm is started in 2014, | |
| 11 that is 10 years ago. | |
| 12 | |
| 13 The current devices model is not very practical. We need to separate the parts | |
| 14 that don't need gpio out of it. All one-wire devices need their own driver | |
| 15 thread. | |
| 16 | |
| 17 | |
| 18 Current threads. | |
| 19 ---------------- | |
| 20 | |
| 21 These are the current running threads. | |
| 22 1. my_devices_loop. | |
| 23 2. my_server_loop. | |
| 24 3. my_panel_loop. | |
| 25 4. my_simulator_loop (if enabled). | |
| 26 | |
| 27 | |
| 28 | |
| 29 Steps to do. | |
| 30 ------------ | |
| 31 | |
| 32 Write a new thread for the one-wire devices. Make it a dynamic table. The | |
| 33 old device table is still needed to tie devices to fermenters. | |
| 34 Try to read all temperature sensors at once. The kernel supports this now. | |
| 35 The devices thread needs to use the collected temperatures. | |
| 36 Read all ds2413 devices from sys/bus/w1. If output bits are set different | |
| 37 then send output values. | |
| 38 Create tables for ds28b20 and ds2413. Simulated and real sensors should | |
| 39 share these tables. | |
| 40 | |
| 41 | |
| 42 Add pigpio library and make it testable by the configure script. | |
