[BUG] timer1 interrupt doesn't work after timer1 NMI interru
Posted: Mon Apr 02, 2018 8:10 amIn core version 2.3.0 analogWrite was implemented by a normal timer1 interrupt. In core version 2.4.0 a timer1 NMI interrupt is used (core_esp8266_timer.c). Therefore in tools/sdk/include/ets_sys.h the function ETS_FRC_TIMER1_NMI_INTR_ATTACH(func) exists. The timer1 NMI interrupt may be detached by using a NULL pointer as parameter for this function. But a normal timer1 interrupt via ETS_FRC_TIMER1_INTR_ATTACH(func, arg) and ETS_FRC1_INTR_ENABLE() doesn't work anymore after. Looks like a bug of the espressif sdk.
