Will Miles	d37ee89e84	ESP8266PWM: Fix phase shift glitches ... In some cases it was possible for the computed phase shift to skip a cycle. Update the shift calculation logic to prevent this.	2024-11-09 21:33:58 -05:00
Will Miles	59deebc961	Improve PWM on ESP8266 ... - Better phase updates without dropping samples - Make second pin duty cycle always after first, even inverted	2024-09-29 10:00:27 -04:00

Will Miles	fe4b668107	Slightly reduce PWM jankiness	2024-09-28 23:12:03 -04:00
Will Miles	cc87b32206	Support PWM phase shifts on ESP8266 ... Use the phase-locked soft PWM from the Arduino core to implement the same PWM phase management as ESP32s are using. The soft PWM code is vendored in, as it was previously, to add the NMI workaround from #4035. Completes #4034	2024-09-28 23:07:28 -04:00
Will Miles	2fc2f47d06	ESP8266PWM: Annotate sources ... Add additional clarification as to the original source URL and the specific local patches.	2024-07-12 19:16:31 -04:00
Will Miles	ff39a8db3f	Fix PWM crashes on ESP8266 ... Vendor in the ESP8266 Arduino core PWM library, with a fix for a nasty NMI crash bug. Sometimes the NMI return instruction seems to fail, resulting in an infinite loop as the PC gets stuck. Work around this by backing up and restoring the PC if needed.	2024-06-27 21:30:05 -04:00
