Or even better.
If you give me HEX file with FW image you want to upload into SUB-20 send it to me an I will convert it to the format acceptable by SUB-20 FW update tool.

OK,
You could use SUB-20 FW Upload Tool.
And I can compile a FW for you and send you image.

Send me zip file with a FW you want me to compile. Our CPU is AT90USB647.
If some pinout configuration required let me know.

OK,
So how do you want to convert SUB-20 hardware to be compatible with schematics you've sent?

Interesting.
Let's say we can compile firmware and provide it for uploading via SUB-20 FW Updater. But what about HW compatibility?

Let's take hypothetical 3-wires cable and connect it to SUB-20 GPIOs this way: GPIO0 --- wire0--- GPIO1 GPIO2 --- wire1--- GPIO3 GPIO4 --- wire2--- GPIO5 First test connectivity -------------------------- 1. Set GPIO 0,2,4 to output 2. Set GPIO 1,3,5 to input with internal pull-up http://www.xdimax....

Hi,
I would suggest you to try latest version
viewtopic.php?f=2&t=3#p353
Let us know if it helped.

Hi,
You do not need all this stuff. It is done inside SUB-20. All you need is to call sub_lcd_write

OK,
I will define something and will send you for review.

Have you tested I2C channels feature?

LEDs are currently controlled by FW to show different statuses.
SW1 and SW2 has no API, none asked for it before.

What do you suggest? How would you like to use it (both LEDs and SW)?
