How to control - command line

Postby rbuelund » Thu Aug 21, 2014 7:55 pm


I'm using my RS232 interface for communication with a GSM module and therefore cannot use it to communicate with the upis. How can i read/write values through the i2c interface using the command line ?? Please state an example.

1.Use the latest firmware release, due to fact that in this version most of the PICo commands are implemented
2. For you reference, use below list of PICo variables and their description

Here it is the 1.096 version

as also resisters update

3. You need to have installed the i2ctools before you use them from command line, please install it

Example of using it

Read seconds of the RTC in BCD format
$sudo i2cget –y 1 0x69 0

$sudo i2cget -y 1 0x6a 1 w
Means 411 of 10th of mV, so it is 411*10 mV = 4110 mV = 4.11 V

Please play little bit with reading variables and then start writing to them to avoid possible problem

Hope it help,
