Raspberry Pi and ST7735 1.8 TFT SPI LCD display.

I have written six books on the Arduino, but only one on the Raspberry Pi.  Now I am working on a second Raspberry Pi book called, "Raspberry Pi LCD Projects".  The third LCD init is this 1.8 inch 128x160 pixel color LCD.  This first picture was taken when I first got it to work doing a Red/Green/Blue test.
Then I worked on the setup configuration so that instead of using 4 bits or 5 bits per color it uses 6 bits per color or three bytes per color.  That way it matches up with the BMP file format making it very easy to display a BMP image.  Sorry but my camera does not show the colors very well.....
I used IrfanView to edit and create this 128 by 160 Raspberry Pi logo image.
At first the BMP pictures appeared to be out of sync.  The problem was that the code for this display that is listed on the Internet is wrong.  The display was not using all of its 128 pixels in the width. After a few tweaks everything came up working as it should.

Here is the video:

More medical problems - Learning to eat healthier

First of all I must say that I am not a doctor nor do I play one on TV.  But the doctors have sure seen a lot of me.  If you are sick see a doctor!

You may be wondering why there has been so few posts and no videos from me for such a long time. Well to put simply I have been sick.  In November I was not feeling well and made a doctors appointment.  I also started taking more supplements trying to stop the downward spiral of my health.  In January the doctor observed lumps in my thyroid and sent me for an ultrasound.  During the ultrasound I noticed that the tech was taking lots and lots of pictures.

Next I was sent for a consult and a biopsy.  They had observed many lumps including two that were about one inch in diameter.  One of the larger lumps had no clearly defined edges and both had unusually high blood flow.  Both of those things are bad signs.  They took three biopsy samples from each of the larger growths.  When they pierced one of the growths I flinched every time even though they had anesthetized me.

When the biopsy results came back, there was no cancer found.  Now they will observe the growths every few months to see if they are growing in size.  Also by this time my health was improving.  I was taking lots of supplements, fasting for 23 hours at a time, and mostly drinking green stuff (Greens Pak).  I am taking Turmeric with black pepper, Una De Gato (Cats Claw), and Super Supplemental vitamins as well as the supplements that I have been taking for years.  I have also eliminated all corn syrup (was in yogurt) and almost all sugar.

I have found issues with some tings that I was eating almost everyday.

Oatmeal - Recent studies found very high levels of herbicides in oatmeal.
They are using herbicides to kill oat and wheat plants for faster harvesting.
I am now eating organic oatmeal instead.

Yogurt - They use corn syrup for a sweetener.
Corn is genetically modified (GMO) to have BT Toxin in the plant.
It is also sprayed with herbicides to kill any weeds.

Pretzels and bread - Wheat products have herbicides in them.
