EQUATIONS EXPLAINED - for the curious
I was fascinated by the simplicity of Marks post 2/8/2011 using the equation
w0 = w0+880/16*9/5-67 to convert from C to F.
what is the 880 and -67?
why not the usual C*9/5 +32? I see now he has divided W0 by 16, thus shifting away the fractional part...
I think this problem stems from a CHROME update... but I get this error when trying to add the app to chrome using a MAC or a PC. Any input or expected fix date? UPDATE: friend downloaded a Version 48 (from february?) for MAC and the error message did not appear... so it is a problem with...
I have shipped a device to Reigate from California. It was $$$!! and I think I may need to reprogram the picaxe inside of it. Is there anyone who could do this for me for a consultation fee? You would need to remove 3 screws in a wooden box to access the program port. You'd need a standard...
Can't get Newhaven NHD-216CW-AY3 OLED display up and running using I2C. Finally got it with SPI so I know my initialization sequence is OK. I think the problem is getting the right I2COUT command format! I've tried several, including hi2cout $00,(Out_Byte1) and hi2cout [$7A],$00,(Out_Byte1)...
This represents about 10 hours of research & experimentation! I tried to create minimal code to get Newhaven’s slim OLED functional. The part uses a US2066 controller – specifically I’m using a NHD-216CW-AY3
