![]() ![]() When the battery reaches the critical voltage, a “Low battery” notification will be shown, then the device will turn off. The voltage measuring process is done using a voltage divider and AVRs internal 1V1 voltage reference. The following equation is used to measure the battery voltage in mV, with the known values R2=10k, R3=3k3, Vref=1100mV, ADCres=1024. Using the 3.5mm male jack connector, the Dintervalometer will trigger the camera to focus and to take a picture. The jack consists of three wires: ground, focus and shutter. To focus the camera, the focus wire has to be connected to the ground. To release the camera both wires have to be connected to the ground. Dintervalometer is tested with Canon EOS 700D. It has a jack plug for remote shuttering. ![]() The software is written in C and compiled with avr-gcc. #BEST TIME LAPSE TOOL FOR CANON 700D SOFTWARE# TIMER: Initializes Timer1 and provides an interrupt based delay function. ![]()
