Hi John,

If you are stuck I will do that .. but the seller advertises shipping to New Zealand in his list there... click on shipping (just to the right of the description TAB... ) It is just his pull down tab that doesnt let you select NZ... Have you emailed the seller as I am not sure of AUS freight costs but it is likely to be more than the item cost to ship it to NZ.

Regards,

Mick

I'm willing too, but shipping to rural Alaska is likely to take longer than to OZ and over. Let me know if you want me to do this. Auction says they only have 3 left.

Hi

I have recieved the I2C radio many thanks to Rob
Now I just cant seem to wrap my head around on how to use the I2C with it.

The I2c address is &H11 with the following Registers that contain 16 bits

Register Bit Name Function Default
15 DHIZ Audio Output 0 = High Impedance; 1 = Normal Operation 0
14 DMUTE Mute Disable 0 = Mute; 1 = Normal Operation 0
13 MONO Mono Select 0 = Stereo; 1 = Force Mono 0
12 BASS Bass Boost 0 = Disabled; 1 = Bass boost enabled 0
11 RESERVED - -
10 CLK32_INPUT_ENB 0 = Enable; 1 = Disable (select 1 if crystal is shared) 0
8:7 RESERVED - -
6:4 CLK_MODE[2:0] 000 = 32.768 kHz (used for this module) 000
1 SOFT_RESET Soft reset; set to 1 to reset. 0
0x02
0 ENABLE Power Up Enable 0 = Disabled; 1 = Enabled 0

That is a write Register

So the question is how do I write to this Register and set the appropiate bits

A read register is as below the Register is 0X0A

Register Bit Name Function Default
15 RESERVED - -
14 STC Seek/Tune Complete 0 = Not complete; 1 = Complete
Flag is set when the seek or tune operation completes.
0
13 SF Seek Fail 0 = Seek successful; 1 = Seek failure
Flag is set when the seek operation fails to fails
to find a channel with an RSSI level greater than SEEKTH[5:0]
0
12:11 RESERVED - -
10 ST Stereo Indicator 0 = Mono; 1 = Stereo
Stereo indication available on GPIO3.
1
0x0A
9:0 READCHAN[9:0] Read Channel
BAND = 0
Frequency = Channel Spacing (kHz) x READCHAN[7:0] + 87 MHz
BAND = 1
Frequency = Channel Spacing (kHz) x READCHAN[7:0] + 76.0 MHz
READCHAN[7:0] is updated after a tune or seek operation.
0x00000000
The timming is as this pic

So i have the following

Dim RegsH(8)
Dim RegsL(8)

I2caddr = &h11 ' RDA5807 I2C address
I2CEN 100,100 ' Enable I2C

I2CSEND i2caddr, 1, 1, &H0A

I2CRCV i2caddr, 1, 8, RegsH(0)
? "0=ok 1=nack 2=timeout"; MM.I2C

I2CRCV i2caddr, 0, 8, RegsL(0)
? "0=ok 1=nack 2=timeout"; MM.I2C

For I = 0 To 7
? I; RegsH(I)
Next I

For I = 0 To 7
? I; RegsL(I)
Next I

This produces the following
I would have assumed the results would 0's as this is the default
and RegsL(array) all 255

> run
0=ok 1=nack 2=timeout 0
0=ok 1=nack 2=timeout 0
0 5
1 63
2 0
3 16
4 88
5 3
6 88
7 4
0 255
1 255
2 255
3 255
4 255
5 255
6 255
7 255

I have atached the orginal PDf and a Parallax version

2012-03-01_165943_FM_Radio_Receiver_Module_Documentation.pdf

Any assistance would be greatly appreciated

Many Thanks

Jman, just had a brief look so I may be way off the mark, but is there not a bit of confusion in your program between bits and bytes? You are reading into a buffer of 8 bytes and then iterating over those bytes in the debug loop. Should you not be reading two bytes High and Low and then dealing with the bits as per the register?
