Time / RTC
The EA uniTFT-Serie has a built-in a RTC. In addition to providing time-stamps for log files, the time and date can be displayed on the screen. On delivery, the time is set to Central European Time (CET / MEZ). Depending on the location it may be necessary to set the device to local time (#WTD). In the event of a voltage drop, or when the module is switched off, the clock is powered by a button cell (D377), so that the correct time is retained. Due to component tolerances and temperature fluctuations, deviations of up to 0.02% are possible. The deviation can be reduced by repeatedly adjusting the time (#WTD). |
