Introduction
We provide a Shell script to set params of VEYE-MIPI-290 on RaspberryPI, which is open source.
Download：i2c_cmd on github
Which I2C
We will use I2C-1 to communicate with VEYE Camera Module on RP3b/b+、CM3. I provide camera_i2c_config script to set the pin multiplexing.
In case you do not know how to use I2C-1, I provide you [How to open I2C-0] below.
### Open [i2c-dev0] device file
1. /boot/config.txt
```shell
dtparam = i2c_arm = on
dtparam=i2c_vc=on
```
2. /etc/modules
`i2c-dev `
3. i2c-0 devices will appear
`ls /dev/i2c-0`
4. Check VEYE-MIPI-290/327 i2c address
`i2cdetect -y 0`
the address is 0x3b
HOWTO: veye_mipi_i2c.sh
Introduction
There are four files:camera_i2c_config、i2c_read、i2c_write、veye_mipi_i2c.sh.
Run camera_i2c_config first to set Pin mux, then veye_mipi_i2c.sh.
camera_i2c_config USAGE
Computer Module
Hardware Connection ：
Use Enhanced Interface Board We provided to attach VEYE Camera Module to CM3.
Attach a VEYE Camera (to CAM1)
Attach CD1_SDA (J6 pin 37) to GPIO2 (J5 pin 5).
Attach CD1_SCL (J6 pin 39) to GPIO3 (J5 pin 7).
Attach a VEYE Camera (to CAM0)
Attach CD0_SDA (J6 pin 45) to GPIO44 .
Attach CD0_SCL (J6 pin 47) to GPIO45 .
Software
Download dt-blob.bin from here， rename it to dt-blob.bin and place it in /boot/，then
./camera_i2c_config [cameranum]
Other Boards
./camera_i2c_config
veye_mipi_i2c.sh USAGE
Usage: ./veye_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2
options:
-r read
-w write
-f [function name] function name
-p1 [param1] param1 of each function
-p2 [param1] param2 of each function
