Simple Menu

[vahithosan]

Hi.
I want to make simple menu with rotary pcd8544 esp32.

I tried some but didn't work

When I use interrupt and interrupt to assign another function, it resets esp32 with machine.disable_irq().

how can i make a simple menu with submenu

Code: Select all

from rotary_irq_esp import RotaryIRQ
import pcd8544_fb
import time
import utime as time
from machine import Pin, SPI

r = RotaryIRQ(pin_num_clk=35,
              pin_num_dt=34,
              min_val=0,
              max_val=4,
              reverse=False,
              range_mode=RotaryIRQ.RANGE_WRAP)

button = Pin(39, Pin.IN)

spi = SPI(1)
spi.init(baudrate=2000000, polarity=0, phase=0)
cs = Pin(15)
dc = Pin(4)
rst = Pin(27)
lcd = pcd8544_fb.PCD8544_FB(spi, cs, dc, rst)

while True:
    rot=r.value()
    if rot == 0:
        lcd.fill(0)
        lcd.text("> HIZ       ",0,0,1)
        lcd.text("  START AYAR",0,8,1)
        lcd.text("  STOP AYAR ",0,16,1)
        lcd.text("  AYARLAR   ",0,24,1)
        lcd.text("  KODLAMA   ",0,32,1)
        lcd.show()
        if button.value() == 0 and button_old == 1:
            lcd.fill(0)
            lcd.text("----HIZ-----",0,0,1)
            lcd.text("            ",0,8,1)
            lcd.text("            ",0,16,1)
            lcd.text("            ",0,24,1)
            lcd.text("            ",0,32,1)
            lcd.show()

When I use interrupt and interrupt to assign another function, it resets esp32 with machine.disable_irq().

Can you post an example of the code that causes this?

i use
MicroPython v1.16 on 2021-06-23; ESP32 module with ESP32
Type "help()" for more information.

Code: Select all

from rotary_irq_esp import RotaryIRQ
import pcd8544_fb
import time
import utime as time
from machine import Pin, SPI

r = RotaryIRQ(pin_num_clk=35,
              pin_num_dt=34,
              min_val=0,
              max_val=4,
              reverse=False,
              range_mode=RotaryIRQ.RANGE_WRAP)

button = Pin(39, Pin.IN)
spi = SPI(1)
spi.init(baudrate=2000000, polarity=0, phase=0)
cs = Pin(15)
dc = Pin(4)
rst = Pin(27)
lcd = pcd8544_fb.PCD8544_FB(spi, cs, dc, rst)


def hiz(p):
    print("deneme")
    time.sleep(5)
    
button.irq(trigger=Pin.IRQ_FALLING, handler=hiz)

when i enter this:

Code: Select all

machine.disable_irq()

I'm pretty sure you can't disable IRQs at the REPL, as the system requires IRQs to function, and you should only be disabling IRQs for very short periods of time (less than milliseconds). (My guess here is what's happening is the watchdog is activating).

[dhylands]

Yeah - there is code here: https://github.com/micropython/micropyt ... #L576-L587 which reenables IRQs if you try to disable them from the REPL (at least if using USB). For the ESP32, it doesn't look like that code path would be taken, and the watchdog would trigger,
