CyberClock CY22150 mit USB und Steuersoftware

1. Hello! I express my gratitude for your project „Cyberclock Cy22150“. I collected „i2c-Tiny-USB“- everything worked, I checked the test with a display 1602. I ask you to help me, I hope it will not be difficult for you. My problem: I came across a CY22150 chip with an address on the 0X6AH bus (instead of 0X69H by default). My request to you: compile for me a program for Windows with address 0x6ah. I am a radio amateur, I have difficulty programming. As I understand it, you need to change in the „i2c_usb.h“ file value 0x69 by 0x6a

   „// CY22150 Chip Address
   #define CY22150_ADDR 0x69 “

   And then get the file „CyberclockControl.exe“
   I hope for your help.

   By the way, maybe you know how to change the I2C address from 0x6a to 0x69 in the CY22150 chip itself?
   This would completely solve my problem with the device where CY22150 is used !!!

2. Hi Dmitry,
   I wrote an addendum at the end of the article and modified the software to change the I2C-Address. Hope that helps.

   Best,
   Uwe

3. Hello. Thank you so much for taking the time to help me.
   CY22150 began to be determined – to respond to Skan – Open usb !!! (frequency = 3.597Mhz).

   But my expectations were not met, CY22150 – does not remember the state of the frequency 3,597 Mhz
   after power off.
   (does not remember in its EEprom).

   So the question arises – should CY22150 remember the frequency value after using CyberClockControl ???

   I read the forum on your link and found interesting information.

   Here is the quote:

   CY22150 Jedec File Analysis!
   ———————————————————–
   If you look at the jedec file for CY22150, although the format may not be obvious,
   it’s also not complicated. Starting with the first block:

   L00064
   0101101000000001000000000000000010000100
   0000011000001000100010001000000011101100
   00110000000000000000000000000000*

   In the first line, 64 is the (decimal) bit address of the first bit. Divide this value
   by 8 to get the byte address. So this string of bits begins at register address 8.
   Divide the bits into groups of 8, representing byte values.
   The bits in each byte are ordered MSB to LSB (left to right),
   so they are shifted into the I2C port in exactly the order shown.
   White space (spaces and carriage returns) are ignored. The above data is shown below as a series of bytes.

   I2C
   address
   08H 01011010
   09H 00000001
   0AH 00000000
   0BH 00000000
   0CH 10000100
   0DH 00000110
   0EH 00001000
   0FH 10001000
   10H 10000000
   11H 11101100
   12H 00110000
   13H 00000000
   14H 00000000
   15H 00000000

   There is a gap of unused addresses, then the next block of data starts at L00512.

   512 / 8 = 64 (decimal) = 40H

   Similar breakdown applies for further addresses. So the bits in groups of 8 following „L00512“
   in the JEDEC file start at 40h and go to FFh. After L00512 shift in 40h to 47h. Settings after
   that do not matter.

   I have written two files to CyClockRT *.Jed with different I2C addresses: 1)69h , 2)6Ah.
   and compared.

   69h=(0)1101001, and (1)1101001 =E9h
   6Ah=(0)1101010, and (1)1101010 =EAh

   The changes are present at 11h !!!!!

   Only the first bit is different, it always = 1.

   Question : is it possible to form a command to write over I2C :

   Device with address 6Ah (CY22150), write the value E9h to address 11h. ???

   I tried (for the first time!!) write a sketch
   for Arduino to change the device address(CY22150).

   Here’s what happened :
   ——————————–
   /*
   sketch_CY22150_Change I2C Address
   */

   #include

   void setup() {
   Wire.begin();

   Serial.begin(9600);
   while (!Serial);
   Serial.println(„\CY22150_Change I2C Address“);
   }

   void loop(){
   Wire.beginTransmission(0x6A);
   Wire.write(0x11);
   Wire.write(0xE9);

   Wire.endTransmission();

   delay(100);
   }
   ————————————————
   The address is changing!!!
   But unfortunately, as in your program,
   the change is not saved in the EEprom(cy22150).
   After removing the power – again 6A….
   Maybe try not to write E9h =(1)1101001,
   but to write 6Ah=(0)1101010 ???
