| + | This is also the case after the RocNetNode has been started until a clock synchronisation came in.\\ | ||
| + | The looping dash is also an indicator that the I2C bus works as expected.\\ | ||

| + | Because this board does not feature an I2C buffer chip, it can interfere with other I2C connected boards.\\ | ||
| + | A possible solution is by using the GCA-PI03 board:\\ | ||

| + | Just prepare a short 4 wire connector cable with GND, VCC, SDA, SCL and the fastclock works in a safe way. | ||
| + | |||
| + | =====Setup===== | ||
| + | {{: | ||
| + | |||
| + | The number of connected displays are scanned at RocNetNode startup, and therefor they must be connected to the I2C bus before RocNetNode starts.\\ | ||
| + | Make sure the display addressing starts with 0x70, default, and further displays should be addressed increased by one. Avoid gaps between the addressing to save I2C bandwidth.\\ | ||
| + | \\ | ||
| + | The clock settings are used for all connected displays.\\ | ||
| + | |||
| + | ====Enable==== | ||
| + | Enable the clock display update cycle.\\ | ||
| + | If disabled the clock displays will show: **- - - -**\\ | ||
| + | |||
| + | ====Date==== | ||
| + | Show the date in the following format: **DD.MM.** \\ | ||
| + | |||
| + | ====Temperature==== | ||
| + | Show the temperature in the following format: **-CC°** \\ | ||
| + | |||
| + | ====Dots==== | ||
| + | In case the clock is running faster then real time the four dots will blink in an endless loop.\\ | ||
| + | |||
| + | ====Brightness==== | ||
| + | The display brightness can be set in the range of 1 to 15.\\ | ||
| + | A value of 15 is the max. brightness.\\ | ||
