OpenGD77

As you wrote you need some more states inside the TS interrupt function. If you receive data from an other radio, you have to transmit the response data header. Otherwise the transmitting radio will send the data again. And when you transmit your data, you will have to handle the received response h...

Thank you both. I didn't know that error correction was applied in the codec, I thought that the received buffer was already corrected. I believe the published DMR data mode adds additional error checking Yes, I saw in the DMR standard docs that data frames are 198 bits long, while voice frames are...

(.upper_text) is not needed. I did try to get the linker to use the section if the section .text_main is full. But that didn't work. Hence the __attribute__ for each function. So this is a leftover. But I did try a little bit more and with some small modifcations: ``` .text_main : ALIGN(4) { *(EXCLU...

There is another option to move complete *.o files to the .upper_text section: .text_main : ALIGN(4) { *(EXCLUDE_FILE(*main.o *codec.o).text* ) *(.rodata .rodata.* .constdata .constdata.*) . = ALIGN(4); _etext = . ; } > PROGRAM_FLASH and .upper_text : ALIGN(4) { *codec.o (.text*) *main.o (.text*) *(...

Yes, that's the only way I found.

The linker by it's own does not seem to be able to handle multiple .text* section.

Roger, you can use that empty space simply by: add a section after .codec_bin_section2: .codec_bin_section_2 : ALIGN(4) { . = ABSOLUTE(0x54000) ; *(.codec_bin_section_2) KEEP(*(.codec_bin_section_2)) } > PROGRAM_FLASH .upper_text : ALIGN(4) { *(.text*) *(.upper_text) . = ALIGN(4); } > PROGRAM_FLASH ...

As Colin wrote it needs a big amount of work to implement SMS. There are different types of data modes defined in the ETSI docs. Each type has to be handled in different ways. An the payload of the messages differs between Motorola, Hytera, ... Each message consists of multiple data frames. And ther...

Only do something for open source projects if they belong to a big organization that is responsible and takes care of possible legal problems.

Even if I didn't contribute much in the last couple of month, I won't do something like OpenGD77 again. Lesson learned. Thank you.

The Channel Details screen is not fully controllable via the QuickKeys system yet, as its quite a complex screen, and I've not had time to implement the individual settings changes. (I don't think Alex implemented full control of this in his original code either) If I don't misremember, only the th...
