PyGamer – Hello my name is

I am gif file

Quite a while back, October 2019, I was trying to see what I could make the Adafruit PyGamer badge do. I kept adding things to the code until I caused it to crash. It would crash in about 10 seconds sometimes. Others it would take a few hours. I was putting it through the paces.

While I was at Hackaday Supercon I showed the badge to some acquaintances. Later that day they said Scott Shawcroft, the maintainer of CircuitPython, wanted to check out the code. Scott stopped by the tables where we were soldering and coding. We were introduced and Scott asked to check out the PyGamer. He watched it crash in about five minutes and asked to check out the code on my laptop.

Back then, when the program would crash on the PyGamer, I would have to reinstall CircuitPython on to the device. Scott thought there might be a leak overwriting into CircuitPython. I zipped the files on the PyGamer and emailed them to Scott as we talked.

The attendees of Supercon received a new device from Adafruit while at the con. It was the EdgeBadge. I put my program onto the new device and it ran with no changes. It also crashed in a few minutes. After about an hour messing with the code on my new toy, the EdgeBadge died. I was wondering if the code was too much for the device.

Here is a copy of the code that would cause the PyGamer to crash with the older version of CircuitPython. I am trying to find a suitable plugin for listing long sections of code. Something to display long sets of code in a scrollable box.

I messed with the repetitive code trying to put it into loops, or functions but didn’t have the skills, or commands to do it. I revisited this code a few times over the next few months. I decided to crunch the code down and try the code on a new version of CircuitPython. The code still crashed, but it was not as deadly as it had been. I would just press the restart button and it would start running again. Yay!!

I managed to keep crashing the PyGamer. I decided to try to use lists (arrays) to handle the loops of the ‘green rain’. That worked well, and dropped the lines of repetitive code by a lot.

Since that worked out well I decided to add another animation on the screen. Even with all this happening on the device it was still crashing. I went back onto the Adafruit forums to see if someone was also having the same kind of trouble, or post my code to have it looked at. There was a newer version of CircuitPython and even NeoPixel.mpy. Now the code is running for hours. This morning I plugged it in and it was stopped in the middle of running after a little bit of time. That must have been a fluke. I plugged it into the wall usb and hung it up on a hook around 8 this morning. It was still running at 5 this evening.

I have cleaned it up a little more and took out unused includes. I also added some comments inside the code. It went from 592 lines of code down to 209. I can probably crunch it down some more and add some stuff.

Perhaps the ‘green rain’ could be changed to sprites to make them fall faster.

BTW, if you know of a better way for me to list the code, especially long code, please let me know. SyntaxHighlighter can make the code into a clickable line to open, but I would rather have a set size box that is scrollable.

EDIT – I added the files to github

https://github.com/gbushta/Hello-I-am

The repo contains both the old file and the newer crunched file.

ESP32 DeepSleep

I have been fighting all day with an ESP32 module. It has 38 pins. Yesterday I got it to be able to get out of deep_sleep using a touch pin using MicroPython. Prior to that I was toggling the onboard LED with a touch pin. Copy the code and use it as you wish.

import machine
from machine import Pin, TouchPad
import time
import esp32
wake = Pin(4, mode = Pin.IN, pull = Pin.PULL_DOWN)
esp32.wake_on_ext1(pins = [wake], level = Pin.WAKE_HIGH)

print('Entering Deep Sleep in 10 seconds.')
time.sleep(10)
print('Time is up.  Going to sleep')
machine.deepsleep()

I put in that time.sleep(10) so I could catch it while it was awake and be able to make changes to the code if needed.

TheMicroPython bin file I am using is esp32-20190113-v1.9.4-779-g5064df207.bin

I’ve decided to add some to the code.

The above code does not indicate when the ESP32 is awake unless you are reading the serial output. I decided to include an LED indicator for when the module is awake. The LED goes out when the module goes into sleep mode.

import machine
from machine import Pin, TouchPad
import time
import esp32
wake = Pin(4, mode = Pin.IN, pull = Pin.PULL_DOWN)
esp32.wake_on_ext1(pins = [wake], level = Pin.WAKE_HIGH)
led = Pin(2, Pin.OUT)

print('Entering Deep Sleep in 10 seconds.')
print('When the blue LED is on I am awake.')
led.value(1)
time.sleep(10)
print('Time is up.  Going to sleep')
machine.deepsleep()
