achushu / ch57x-keyboard-mapper Goto Github PK

Does anybody know which group I need to add to my account to be able to run it without using sudo?

I have a keyboard with no layer switch and I've found a strange behaviour; when programming the keyboard the layer that will upload and work is the last one on the yaml file but upon loosing power (reconnecting the device or restarting pc) the keyboard will default to the first layer on the file for some reason. It's not really an issue, I just copied the same config on all layers but it's something that may be worth adding to the readme for some folks.

Hello,

firstly a big thanks for your work!

I have zero to nothing experience with go, but I tried my best to get a bit into it.

But I am not able to get the Mediacodes to work with my Macropad.
It has 3 Keys + 1 Rotary-encoder, the µC is a CH552g. So far I somehow managed to set "normal" keys and things like CTRL+C.

Bit if I Enter e.g {NOMOD, PLAY} It seems not to overwrite the existing code for this key.

Am I doing something wrong? Or is there maybe a bug?

Thanks in advance :-)

I don't know that this is an issue for @achushu so much as a place for me to document the issue, but programming on Mac is not going well.

I checked, and the Product ID is 0x8890, and Vendor ID is 0x1189, Manufacturer wch.cn. I noticed that in the code, this is presented in decimal form, but I've tried it both ways, and I get the same result. I even have it print them before tossing the error, and it is returning decimal form:

// manu: wch.cn, product: CH57x, vendorID 4489, productID: 34960

const (
	VENDOR_ID  = 0x1189
	PRODUCT_ID = 0x8890
	INTERFACE  = 1 // the programmable interface
)

Garou:~/git/CH57x-keyboard-mapper  tshadwick$ ./ch57x
4489
34960
could not find the device interface

So the device is there, but can't be found. Perl is my primary language, so I took a brief stab of enumerating the device using libusb there.

Garou:~/git  tshadwick$ perl usb_probe.pl
Bus 020 Device 005: ID 1189:8890
Bus 020 Device 004: ID 291a:8352

Bus 013 Device 006: ID 0bda:8153
Bus 013 Device 005: ID 291a:0817
Bus 020 Device 003: ID 291a:2817
error in libusb_claim_interface: Access denied (insufficient permissions) at /Users/tshadwick/perl5/lib/perl5/darwin-2level/USB/LibUSB/Device/Handle.pm line 22.

Hmm. Did some googling, and wind up on the libusb wiki:

How can I run libusb applications under Mac OS X if there is already a kernel extension installed for the device and claim exclusive access?

Thing is, I'm having a hard time determining what is holding onto the device. I had thought kextstat could list devices and what kernel driver was attached, but now I'm at a loss. @achushu, do you happen to know if this thing is using a serial chipset like the FTDI?

Hi,
I've compiled your code, but when I try to execute it it says "this platform / binary does not support HID",
I've tried to have a look around for that error but I haven't found anything.
I'm on Windows 10 Pro.
Thanks!
