Keyboard lag #36

I'm typing this up on a plaid and it's pretty hard going. There's lag in polling key presses, mostly after a period of not typing anything.

I've burned the bootloader myself using the standard fuse bit settings. It burns successfully and keymaps can be subsequently uploaded.

Hi, I have never had such a problem in my environment. Since the USB device is emulated by software, it may be a limitation of the MCU's performance or something. I'm sorry this isn't helping, just information.

My MCU is an ATMEL ATMEGA 328P U, which I'm assuming is what everyone else uses for this keyboard? The odd thing is that it is as if it takes a couple of seconds to wake itself after a key press when left unattended for a while (around 30 seconds). This makes me think it is either a fuse bit setting or a firmware setting. I'm using a fairly up to date version of QMK (around June 2021).

Never mind. The keyboard is working now using the standard fuse bits and v-usb standard firmware and I'm pretty sure it must have been an external problem. Probably a loose cable, or extreme low temperatures or something.
