Possible documentation improvements

[sherylll]

I think it should be pointed out that the library only works with python3, in my case I had to use sudo python3 pyficlibtest.py

Also the ring_8bit.bin file does not exist in the repository. Maybe this could be added?

You need add your account to 'gpio' group else you need sudo.

Also the ring_8bit.bin [1] file does not exist in the repository. Maybe this could be added?

I don't think this is good idea.

Hi Nyacom-san,

I have been trying out some of the APIs, and was able to program the bin files, for example

fic.gpio_open()
bit=open("lenetio.bin","rb").read()
fic.prog_init()
fic.prog_sm16(bit,1)

but when I try to use wb4, hls_start4 after the programming of the configuration, I got a timeout

ERROR: Communication timeout at ficlib2.c fic_comm_wait_fack_down 171
ERROR: fic_comm_wait_fack_down failed at ficlib2.c fic_comm_send4 279

Could you provide more information about how to use those functions?
Thanks!

Well, you need reset/start of HLS module before communicate because HLS part is not running when the FPGA configured. then if you want to communicate HLS part, you should use hls_send4/hls_receive4. wb4/rb4 is a API for communicate FPGA register itself. (not for HLS) (Personally, I don't like this design, but Hunga-san designed like this.. ) In addition, i have not well tested for hls_send4/hls_receive4 due to time restrictions. so I think the APIs should be need some fixes. (can you help me?) I hope you would make some little HLS module that just write and reply to/from 4bit HLS I/F for testing. How do you think?

I discovered that I must use 'fic.prog_sm8(bit,0)' to program, instead of 'prog_sm16'

I'll try to make some documentation about my trial and errors... And yes I think there should be some self-contained examples (HLS module + python script) demonstrating how to use the APIs.

[sherylll]

As of now there is no APIs for setting the tables, right? Is it on the radar?

Oh yes. It is depends what did you generate *.bin files with according program modes in the vivado. so if you are using SM 8bit prog mode *.bin file, you should use prog_sm8 instead of _sm16.

It is already implemented. Use _wb8 or _wb4 for table register address to set the table. Anyway, I also implemented table can be set via web GUI. (not deployed yet..) Cheers,

Hi Nyacom-san,

if I understood it right, hls_send4 and hls_receive4 are equivalents of write_byte and read_byte of the C library, correct?

How could I use read_cont and read_fin (or how should I go about programming them?)

FYI I have made a hello world example here: https://github.com/hungalab/FiC-first-example and I am trying to get the Python script work...

Thanks!

Nope. write_byte and read_byte in C library (are you mentioned about hunga's original C library?) are equivalents of wb8 or rb8 in ficlib2.

How could I use read_cont and read_fin (or how should I go about programming them?)

As you can see hld_send4 and hls_receive4 has data and its size arguments. these functions are will finalize the communication at the end hence you no need to do read_fin/cont. BTW, I did not well tested for hls_receive4. Prolly I need more investigation about this. I am appreciated if you are testing about this.. Cheers,
