Description
Error 2 description
sometimes incorrect readings when reading ADC channel
Reproduce
no solid reproduction process, but happening intermittent
root cause
Interrupt reset mask is not initialized before being used
by calling am_hal_adc_interrupt_clear()
Solution
Initialize the interrupt reset mask with 0xff to reset all interrupts
########### in ap3_analog.cpp ################
**************routine analogRead(uint8_t pinNumber) ******************
in the top:
change:
uint32_t ui32IntMask;
To :
uint32_t ui32IntMask = 0xff;
