* CH341: fewer waits on the USB bus per radio command Every RadioLib command to a radio behind a CH341 waits on the USB bus about five times: the BUSY read before it, CS low, the command, CS high, and the BUSY read after, with a 1 us settle between the last two that usleep() turns into ~50 us of timer slack. - A BUSY read that follows the read that found BUSY low after a command is answered from it, once, within 1 ms and only if nothing else has been sent to the adapter in between: RadioLib's wait before a command then costs nothing after the wait that ended the last one. - Delays under 100 us spin on the steady clock instead of sleeping. - With a libch341 that has pinedio_transceive_select(), and where Lora.CS is D0, the CS levels travel with the SPI transfer and RadioLib's separate CS writes are dropped. Against an older libch341 this part compiles out. The HAL learns the radio's CS and BUSY pins from initLoRa(), since USBHal.h is included by PortduinoGlue.h ahead of portduino_config. Measured on an SX1262 over a CH341 (SHORT_TURBO, 6 v 6 runs of 300 s): the three-command CAD setup fell 1.01 -> 0.62 ms, CAD arm to air 6.60 -> 5.23 ms, and total packet loss 1.51 -> 1.13% (p=0.048), with collisions 4.83 -> 0.67 per run (p=0.002).
