Soldering - I need to do some soldering work today. A few esp development boards need header pins.

Please sit near an open window while working with soldering iron and tin. Solder tin and flux fumes are not healthy. I tend to hold my breath while soldering.

There are different types of esp development boards. Today I soldered header pins onto a few of them. Nothing fancy. 
I have to flash MicroPython to their flash memory after soldering is done.

I want to test using ssd1306 OLED to show an image. The idea is to snap a picture using an esp32-cam and show the image to an OLED connected to an esp8266 situated at a different place.

The problem is that the image capture is 1600x1200 jpg while the OLED that I will be using will only take a 128x64 pbm format. Somewhere between image capture to image display, a downscaling, filtering, and conversion, need to be done.

I am using Python PIL module on a Linux desktop to do the heavy job of processing a captured image. I did this manually for now. When all the necessary hardware and software parts are in place, an automatic process of capturing and displaying of images would not be difficult to conceive.

The simple architecture will be an esp32-cam, a Linux server, and an esp8266 connected in a TCP/IP  client/server sockets network. The esp32-cam snap a picture and send it to the Linux server. The Linux server process the image received. The server then sends the processed image to an OLED display controlled by the esp8266.

Custom made - Sometimes, it is nice to be able to build custom made things. Thanks to Damien George and all the clever people at micropython.org for making it easy. So that, to custom build a micropython is not that difficult. Why do you want to build customize firmware anyway? Well, you might want to include some functionalities of your own and removed some functionalities from the standard distribution. The choices are there for you to make. I have a few changes that I want to make in micropython. version header -kaki5 (pronounce kaki-lima) an additional thread cleanup function for esp32 add frozen modules CryptoXo and uasyncio remove help, upip, and webrepl camera C module for esp32 camera board These are accomplished by modifying and adding files. py/makeversionhdr.py py/modthread.c extra/CryptoXo.py, extra/uasyncio.py, and manifest.py mpconfigport.h main.c and modcamera.c I also want to remove some modules specifically, help, upip, and webrepl from esp32

Multi-threading : I previously used an uasyncio webcam server. This time around, I am testing a multi-thread webcam server. The result is promising. A multi-thread server seems to give a better throughput. The program logic is simpler when compared to the server based on uasyncio. The server is a four threaded application, two for port 80, one for port 81, and port 82 runs on the main thread, which blocks the REPL.  You can start a dedicated thread for port 82 if you do not want to block the REPL. I found pix/7 gives the best performance. A spe/2 will reduce the image size but give you a grayscale image. Please see my previous blog if all these seem mysterious to you. I have compiled a new firmware, MicroPython v1.11-571-g7e374d231.  You can download the new firmware from my repository at GitHub. The soft reset is not functioning properly. You need to do a hard reset. I also include four new functions in modcamera.c: pixformat agcgain aelevels aecvalue The pixformat chan

Micropython - v1.11-498 introduced a few changes in the source-code directory structure. Changes to specific files, as previously described in esp32-cam , will no longer work. A simple working summary on how to build esp32-cam firmware is described below: Make a recursive copy of ports/esp32 to ports/esp32-cam, and you will need to modify the following files: 1) ports/esp32-cam/main.c 2) ports/esp32-cam/Makefile 3) ports/esp32-cam/modcamera.c 4) ports/esp32-cam/mpconfigport.h 5) ports/esp32-cam/boards/manifest.py 6) ports/esp32-cam/boards/sdkconfig.base Or, you can just download a precompiled Micropython v1.11-498 from firmware.bin at GitHub if you want to save some work. However, I encourage you to compile the firmware yourself. You will learn a lot and you can choose to modify anything to your liking. The modcamera.c includes something new. The still photo was taken using these settings; pix =8, con =2, qua =10, and spe =2. You will understand those parameters, later
