/etc/imraa.conf | |
Defines how pins will be used: | |
{ | |
"lockfile-location": "xxx", | |
"Platform" :[ | |
{"id":"512", "type":"GENERIC_FIRMATA", "flash":"/var/cache/101/firmata.img", "usbserial": "auto"} | |
], | |
"IO" :[ | |
{"type":"gpio", "index":0, "raw": false, "label": "none"}, | |
{"type":"i2c", "index":0, "raw": false, "label": "i2c-0"} | |
] | |
} | |
1. runs mraa_init(), initilise platform, if subplatforms set to flash then do so | |
2. write pinmuxing to set IO into mode via mraa:XXX calls and then setting ownership to 'false' so close/cleanup never happens | |
3. writes json lockfile in /tmp/ with subplatform ids | |
{ | |
"Platform" :[ | |
{"id": "0", "type":"NULL_PLATFORM"}, | |
{"id":"512", "type":"GENERIC_FIRMATA", "uart": "/dev/ttyACM0"} | |
} | |
4. when mraa_init() runs check for lockfile, if lockfile read subplatform info |
