[Question] About KernelFile

MartinDuarte

Hello. I'm developping a project and I wrote a code in C under KeilC enviroment, I did some tests but now, I would like to go back and use DWINOS 8283 native communication protocol. From DWIN support:

UART 2(82 83) is based on DWIN protocol, under our OS kernel.
When you use 8051,keil c, it will clear the internal OS kernel. then 82 83 can't use.
If you wanna use, there are two options
1) Download OS kernel, then could recover, but C51 not existing
2) Write your own protocol in C51, like 82 83, then it could work.

i've acquired kernel flash tool PGT05, and I could successfuly download the corresponding kernel file following the steps in the pdf.

The problem is, when powering up the screen, my old C code from KeilC is still there (because of some initialization prints on UART2 COM terminal) and there is no answer from the LCM.
I reload the CFG file now configuring the erase of flash memory and still nothing happens.

Any ideas?

you just need reload our DWIN OS kernel by SD card:http://inforum.dwin.com.cn:20080 ... 3D1&_dsign=665723fb

Thank you very much for your fast response. It worked for me. Excuse me if I am curious, but why the name of the file stands for "no ack" ?

it means no return when use 0x82 code.
