◆ setRegister()

void BK108X::setRegister	(	uint8_t	reg,
		uint16_t	value
	)

Sets a given value to the device registers.

For write operations, the device acknowledge is followed by an eight bit data word latched internally on rising edges of SCLK. The device acknowledges each byte of data written by driving SDIO low after the next falling SCLK edge, for 1 cycle.

An internal address counter automatically increments to allow continuous data byte writes, starting with the upper byte of register 02h, followed by the lower byte of register 02h, and onward until the lower byte of the last register is reached. The internal address counter then automatically wraps around to the upper byte of register 00h and proceeds from there until continuous writes end.

The registers from 0x2 to 0x07 are used to setup the device. This method writes the array shadowRegisters, elements 8 to 14 (corresponding the registers 0x2 to 0x7 respectively) into the device. See Device registers map in BK108X.h file.

To implement this, a register maping was created to deal with each register structure. For each type of register, there is a reference to the array element.

Parameters

device register address

◆ seekSoftware()

	)

Seeks a station via Software.

Todo:: it is not working properly

Seeks a station up or down.

Seek up or down a station and call a function defined by the user to show the frequency during the seek process.

Seek begins at the current channel, and goes in the direction specified with the SEEKUP bit. Seek operation stops when a channel is qualified as valid according to the seek parameters, the entire band has been searched (SKMODE = 0), or the upper or lower band limit has been reached (SKMODE = 1).

The STC bit is set high when the seek operation completes and/or the SF/BL bit is set high if the seek operation was unable to find a channel qualified as valid according to the seek parameters. The STC and SF/BL bits must be set low by setting the SEEK bit low before the next seek or tune may begin.

Seek performance for 50 kHz channel spacing varies according to RCLK tolerance. Silicon Laboratories recommends ±50 ppm RCLK crystal tolerance for 50 kHz seek performance.

A seek operation may be aborted by setting SEEK = 0.

It is important to say you have to implement a show frequency function. This function have to get the frequency via getFrequency function.

Example:

BK108X rx;
 
void showFrequency() {
   uint16_t freq = rx.getFrequency();
   Serial.print(freq);
   Serial.println("MHz ");
}
 
void loop() {

 .
     rx.seek(BK_SEEK_WRAP, BK_SEEK_UP, showFrequency); // Seek Up
 .
 .
}

Parameters

seek_mode	Seek Mode; 0 = Wrap at the upper or lower band limit and continue seeking (default); 1 = Stop seeking at the upper or lower band limit.
direction	Seek Direction; 0 = Seek down (default); 1 = Seek up.
showFunc	function that you have to implement to show the frequency during the seeking process. Set NULL if you do not want to show the progress.
