 * [[Мajestic]] ➤ new (in development)  audio/video streamer of the OpenIPC based system

+#### MiniHttp is the main streamer of the OpenIPC based system
+
+It is important to tune configuration of MiniHttp by turning off unneeded protocols and features for better security and performance.
+
+Config file is located in
+`/etc/minihttp.ini`
+
+#### Debug mode:
+
+```killall -sigint minihttp; sleep 1; export SENSOR=`ipctool --sensor_id`; minihttp```
+
+#### Production mode:
+
+```killall -sigint minihttp; sleep 1; export SENSOR=`ipctool --sensor_id`; minihttp 2>&1 | logger -p daemon.info -t minihttp &```
+

+## Custom build tools used in OpenIPC OS
+
+[Tools repository](https://github.com/OpenIPC/packages/tree/main/utils)
+
+[ipctool](https://github.com/OpenIPC/ipctool) - gets information about hardware and outputs it in common format. Can also be used to make backup and restore of the camera software (still experimental feature).

+## Prometheus node configuration
+
+[Prometheus](https://prometheus.io/) is an open-source systems monitoring and alerting toolkit.
+
+OpenIPC has prometheus node exporter as a package. The result output can be viewed as a plaintext:
+
+http://192.168.1.10:9100/metrics
+
+Or visualized if you install [proemetheus server and graphana](https://prometheus.io/docs/visualization/grafana/):
+
+[[images/preometheus_node_graphana_example.jpg]]
+
+You can configure the node here
+
+`/etc/config/prometheus-node-exporter-lua`

+## Experiments with I2C on Hi3518EV200
+
+### Setting up i2c-x via device tree
+
+The standard i2c-hisilicon driver does not give an option to set pins to i2c mode if they were previously set to dts. To automatically set the required pins to i2c mode you just need to add the following code to the beginning of hi_i2c_hw_init (linux/drivers/i2c/busses/i2c-hisilicon.c)
+
+```
+#ifdef CONFIG_ARCH_HI3518EV200 // Might be the same for other hardware devices
+if(pinfo->mem->start = 0x200d0000 /* address i2c-0 */) {
+    writel(0x2, 0x200f0040);
+    writel(0x2, 0x200f0044);
+}
+if(pinfo->mem->start = 0x20240000 /* address i2c-1 */) {
+    writel(0x1, 0x200f0050);
+    writel(0x1, 0x200f0054);
+}
+if(pinfo->mem->start = 0x20250000 /* address i2c-2 */) {
+    writel(0x1, 0x200f0060);
+    writel(0x1, 0x200f0064);
+}
+#endif
