Hello everyone, do not worry, the code has been written and all options are enabled. I will give all participants the code and full LCD wiring. This little beast is rocking like hell. Please not that for this chip the isolated i2c is not working. The i2c line of the MCU has to be connected directly to the i2c line of the DAC chip. I will mail all participants the modified wiring for the MCU. The isolated i2c chip and its associated parts can be omitted. I will be most probably receiving the parts this week and will be shipping out the boards shortly.

Perfect and thank Syllabe!
Could we have the source code, modify some things...like the source name in the lcd screen for example?
Thanks again.

I2C isolation does'nt work even without R17, R20 and D1 replace by a wire?
Not enough current for the SDA/SCL output of the K2M?

R17 and D1 should be there, omit R20, R21, R22, R27, C35, C41, IC7. SCL, SDA, GND of the mcu should be connected directly to SCL, SDA lines of the DAC at the point where R20 and R21 connects to SCL and SDA line of the DAC. It worked in ES9018S but it is not working in ES9018K2M chip.

Waiting for the board .
I think I know how to resolve I2C isolation.
After receiving the board I will try some personal idea about this issue.

I am also working on the I2C isolation, according to the i2c specification sheet, I2C requires pull up resistor, faster communication speed requires smaller resistor,
In the schematics, the ES9018K2M's pin 21 show DVDD with the DVDD label!
Where is the regulator for this voltage in the schematic?

DVDD voltage is internally generated for the latest version of ES9018K2M chip.

syklab you have given just c/o Excel technology International, Hong Kong in your PayPal postal address, you have not given any pincode, is this correct??? I will just ship the package to the PayPal postal address only, in case if there is any problem with the address I will not be responsible

Hi ,
I have sent you PM in regarding to my delivery address, seems like paypal messed the address after processing the partial refund. My delivery address should have been stated on my payment detail.
Thanks
I took the address from your PayPal payment page and not the partial refund page. It is the same address as in your PM. Again there is no postal code, anyway I have packed with the same address as you have PM'ed.

Hi,
There is no postal code or zip code for HK, just the street address and city code and follow by the Country code.
Thanks
All boards has been shipped out. Please note that for the next batch of GB for this board if anyone interested i will provide the XG1000 crystal only if Crystek is not available from Digikey at the time of purchase, because for the boards already shipped out the required quantity of Crystek crystal was not available at Digikey at the time of purchase, so i had to wait for some time which caused some delay in shipping the boards. For the DAC IC and XG1000 crystal i can provide any quantity but i cannot guarantee the availability of Crystek at Digikey. If it is available i will provide that and if not i will provide the XG1000.
A slight delay with reason is OK for me.
Saw the tracking in my Paypal. Thanks for the great efforts🙂
