Control BH1415 with a 16f88

[savnik]

Until today i have use the pic16f88 to control a TSA 5511.
My problem now is how to control a BH1415 with pic16f88, because this chip has data - clock and enable.
I have found code , but is for C ,and i don't now.



int setFreq[] = {1,0,1,1,1,1,1,1,1,1,0,1,0,0,1,0};
// set the frequency to 102.1 MHz and other config bits for audio IC
// write_to_chip - write enable, clock, and data bits to audio IC
void write_to_chip(){
int i,j;
PBOUT |= 0x01;
for(j = 0; j <= 10; j++) // set a clock delay
asm("nop");
for(i = 0; i < 16; i++){
if(setFreq[i] == 1)
PBOUT |= 0x04; // set data bit
else PBOUT &= 0xFB;
for(j = 0; j <= 10; j++) // set clock down delay
asm("nop");
PBOUT |= 0x02; // turn clock on
for(j = 0; j <= 10; j++) // set up clock delay
asm("nop");
PBOUT &= 0xFD; // turn clock off
}
PBOUT &= 0xFE;
}

this should help you convert it even though it is for converting c to proton you should still get the idea

Try this;

i var byte
j var byte
setfreq var byte
PBOUT var PORTB ' my assumption here. have no idea what PBOUT is.
TRISB = 0 ' not sure if this is what you need, but..

Main:
gosub write_to_chip
goto Main

write_to_chip:
PBOUT = PBOUT | 1

for j = 0 to 10
@ nop
next j

for i = 0 to 15
lookup i,[1,0,1,1,1,1,1,1,1,1,0,1,0,0,1,0],setfreq

if setfreq = 1 then
PBOUT = PBOUT | 4
else
PBOUT = PBOUT & $FB
endif

for j = 0 to 10
@ nop
next j

PBOUT = PBOUT | 0x02;

for j = 0 to 10
@ nop
next j

PBOUT = PBOUT & $FD
next i

PBOUT = PBOUT & $FE
RETURN
You could probably replace the j loops & nops with pauseus x if you knew the
time delay required for x.

and page 17
Anyone know how to control this chip (BH1415) ;

Do you not have the bh1415f datasheet?
It explains how to set the frequency in there...all easily done with PBP's SHIFTOUT commands...

bits 0 - 15
1,0,1,1,1,1,1,1,1,1,0,1,0,0,1,0

bits 0-10 = frequency, in this case 102.1Mhz
bit 11 = mode, in this case stereo
bits 12-13 = phase detector operation, in this case normal
bits 14-15 = test mode, in this case normal operation

It's right there on the last 2 pages of the bh1415f datasheet from ROHM.

I have the bh1415f datasheet and i have read , but i don't know how to send the data to bh1415f , because this chip has data,clock and enable
For the TSA551 i don't have problem.I have use it many times , but this have only data and clock and use I2CWRITE SDA,SCL,ADDR1,[HI,LO,$8E] to send the data

I have understand , but i don't have use before the command shiftout.




Include "modedefs.bas"

dataout = %1011111111010010

I test today this code but don't work
