@brief E4000 tuner module declaration
One can manipulate E4000 tuner through E4000 module.
E4000 module is derived from tuner module.
@par Example:
@code
// The example is the same as the tuner example in tuner_base.h except the listed lines.
#include "tuner_e4000.h"
...
int main(void)
{
TUNER_MODULE *pTuner;
E4000_EXTRA_MODULE *pTunerExtra;
TUNER_MODULE TunerModuleMemory;
BASE_INTERFACE_MODULE BaseInterfaceModuleMemory;
// I2C_BRIDGE_MODULE I2cBridgeModuleMemory;
unsigned long BandwidthMode;
...
// Build E4000 tuner module.
BuildE4000Module(
&pTuner,
&TunerModuleMemory,
&BaseInterfaceModuleMemory,
&I2cBridgeModuleMemory,
0xac, // I2C device address is 0xac in 8-bit format.
CRYSTAL_FREQ_16384000HZ, // Crystal frequency is 16.384 MHz.
E4000_AGC_INTERNAL // The E4000 AGC mode is internal AGC mode.
);
// Get E4000 tuner extra module.
pTunerExtra = (T2266_EXTRA_MODULE *)(pTuner->pExtra);
// ==== Initialize tuner and set its parameters =====
...
// Set E4000 bandwidth.
pTunerExtra->SetBandwidthMode(pTuner, E4000_BANDWIDTH_6MHZ);
// ==== Get tuner information =====
...
// Get E4000 bandwidth.
pTunerExtra->GetBandwidthMode(pTuner, &BandwidthMode);
// See the example for other tuner functions in tuner_base.h
return 0;
}
@endcode
