I use openmv h7 and excelitas digipyro pyd1588, my code is :
def pin_ready():
Pin('P3', Pin.OUT_PP)
Pin('P3').off()
_regmask= 0x1000000
_val =0x00325D10 # 0x00304D10
_pin = Pin('P7',Pin.OUT_PP)
_pin.value(0)
for i in range(0,25):
nextbit = (_val&_regmask)!=0
_regmask >>=1
_pin.value(0)
_pin.value(1)
if nextbit:
_pin.on()
print("1")
time.sleep_us(100)
else:
_pin.off()
print("0")
time.sleep_us(100)
_pin.off()
time.sleep_us(600)
sensor.reset()
# Bypass internal regulator
sensor.__write_reg(0x4F, 0x18)
# Shutdown the sensor.
sensor.sleep(True)
ext = ExtInt(Pin('P3'), ExtInt.IRQ_RISING,Pin.PULL_DOWN, callback)
Pin('P3', Pin.OUT_PP)
Pin('P3').off()
Pin('P3', Pin.IN)
print(ext)
time.sleep(1)
machine.deepsleep()
pin_ready()
but when openmv command start and it is going to sleep my ‘P3’ pin get high but it should be low, my all wired is true, ı am sure.
Is this a bug or something and is there any way to manipulate pins while in deepsleep mode
