WIZ108SR 9-bit serial data

Question

In the WIZ108 SR description it is stated that you can set data bit length to 9. As my application needs it. When I try to set the data bit value to 9 in configuration tool it comes with an error message : INVALIDPARAM:DB. Do you have suggestions ? Firmware is v.4.06 . Other parameters changed will be saved with no problem. Do you have a special FW for 9 bit serial ?

Kei · Answer

Sorry … The datasheet is incorrect. Unfortunately, the 108SR does not implement 9bit data bits. In addition, due to the internal circumstances of the company, additional code support is difficult. Do you have to use 9bit?

mvoiculescu: In the WIZ108 SR description it is stated that you can set data bit length to 9 I have updated the data sheet. I’m sorry we confused you.

Also : is there an older FW that worked with 9 bit data word ? I am very interested in this and it would open the door for a lot of usages for WIZ108SR . Thanks again, Mike

I looked at the W7100 programming guide and it says that the UART has a Mode 3 in which the data word is 9 bit and the data rate can be customized at around 560 kbps ( needed by my application ). Therefore I think the FW can be modified. Do you have the source code for the WIZ108SR firmware ? I can try to modify it to see if it works for my parameters. Thanks, Mike

Did you check the UART document in the Application Note? I checked the contents now. mvoiculescu: Do you have the source code for the WIZ108SR firmware ? I can try to modify it to see if it works for my parameters. As a company principle, it is not possible to provide the firmware of the module to the customer. Please contact us directly at support@wiznet.io with the following information: Your Company Name Products Used and Production Thanks. BR, kei.

There is only application note v.1.0 which has 4 pages and no mention of the UART. What is the AN that you refer to ? And , yes I will send an email to support@wiznet.io with my details. Tnx, Mike

mvoiculescu: I looked at the W7100 programming guide Is not that the W7100A guide? Anyway, I checked that your email was received. Answers will follow after discussing internally.

Kei · Answer

Could you send me your e-mail address in the Discource forum message, because the e-mail address might be wrong?

mvoiculescu · Answer

Yes, but I received emails from you with NDA attachments on both addresses. My emails : mihai.voiculescu@turner.com and mvoiculescu@verizon.net

Kei · Answer

I have retransmitted to you. Please check and let me know

mvoiculescu · Answer

I am sorry I did not receive anything. I don’t know what might happen. Maybe you have to change the file extension ? Thanks, Mike

Kei · Answer

The zip file extension appears to be a problem. I have emailed you again so please check.

mvoiculescu · Answer

I am sorry Kei : I did not receive anything Thank you, Mike Forum

Kei · Answer

mvoiculescu: I did not receive anything I just sent a test email without an attachment. Please check.

Kei · Answer

The drop box used by the company does not exist, so I changed the extension name and sent it again. You can use it by changing the extension .7 to .7z and unzipping it with 7zip.

Kei · Answer

I have shared a drop box with your mail. Please reply when download is completed

mvoiculescu · Answer

Thanks a lot : the download is complete . I think I replied already on your other email.

mvoiculescu · Answer
