2.17 Camera compatibility (EASY CAMERA)
The GE864 / GC864 provides a direct support for the camera whose characteristics are the following:
Model: TRANSCHIP TC5747
Technology: CMOS COLOR camera
Max picture size: VGA 640x480 pixels
Output format: JPEG
Sensitivity: 4V/lux-sec (including gain)
The camera will be directly managed by the hardware/software with some interface circuitry,
providing a custom AT command interface to operate with it.
The camera interface requires the pins and GPIOs:
Signal GE864 ball GC864 pin
CAM_SDA D7 36
CAM_SCL C6 35
CAM_CLK F8 44
CAM_ON K11 67
CAM_RST C9 76
When the camera is activated, then these pins are not accessible as GPIO.
The AT commands of the module allows to take a snapshot and successively download it through
the serial line in various formats.
2.18 Converters
2.18.1 ADC Converter
The on board A/D are 11-bit converter. They are able to read a voltage level in the range of 0÷2
volts applied on the ADC pin input, store and convert it into 11 bit word.
Min Max Units
Input Voltage range 0 2 Volt
AD conversion - 11 bits
Resolution - < 1 mV
Sampling rate 1 (idle) 60 (on traffic) secs
2.18.2 DAC Converter
The on board DAC is a 10 bit converter, able to generate a analogue value based a specific input
in the range from 0 up to 1023. However, an external low-pass filter is necessary. See the HW
User Guide for the details.
