Descrizione
I cambiamenti:
– HackHD now records properly on microSDXC cards and will save the video in 4-5 GB chunks. This allows for double the recording time on a 64GB microSDXC. The original firmware worked with microSDXC cards but would not save the video in chunks and if it got too big it would not be able to be opened.
– LED blinks fast and HackHD turns off if no memory card or error. The original firmware allows the the unit to remain on, thus draining the battery.
– To enter standby mode, you only have to hold down the button approximately 1 second (until the LED goes bright). Release and wait. Once the LED flashes quickly 2 times, the camera is ready to record in standby mode. The original firmware required the button be held down for 4 or 5 seconds and has no indication that the unit entered standby mode.
– Unit will turn off when battery too low for camera operation. The original firmware kept the unit running until the battery ran out.
– Debounce rate set to 60ms which means that the button must be pressed down for a minimum of 60 milliseconds (0.6% of 1 second) to count as an active button press. On the original firmware, there were issues of accidentally entering auto mode when trying to hold down the button to enter standby mode since the debounce rate was too low and very sensitive which sometimes caused the board to think the button was released prematurely even though it was not.
Firmware Installation Instructions:
It is crucial these instructions are followed correctly otherwise the HackHD can become permanently defective. If you are having problems installing the new firmware, try first formatting your SD card in Fat32, NTFS, exFAT or trying another card before putting main.elf on it.
1. Put the firmware file (always called main.elf) in the root directory on your microSD card.
2. Insert the microSD and connect an LED, switch, and fully charged battery or external power supply (between 3.7V and 5.5V) to the board.
3. Power up the camera in standby mode. You will know it is in standby mode with the LED remains solid. If the LED beings slowly flashing, it is possible the camera either booted up in auto mode or was accidentally triggered to start recording in standby mode. If this is the case, press the switch again, if the LED goes solid, the camera is in standby mode ready for the next step. If the LED turns off, the camera was in automode so try again to enter standby mode.
4. Once you confirmed the camera is in standby mode and not recording, hold down the switch. After a few seconds, the LED will turn off and then a few seconds later the LED will turn back on. As soon as the LED turns on, immediately release the switch, it is important to do this within half a second of the LED turning back on. The LED will remain on for up to 30 seconds at which point it will turn off with the camera. When the LED turns off, the firmware upgrade should be successful. The video out signal shows the firmware version on the bottom of the feed.
