Re: Speed

Ahh that explains why that u8glib worked but was incredibly dark. It wasnt turning on the supply.

That benchmark test was only designed to see if i could tweak setpixel, it didnt seem to make much of a difference to text.

It DID make drawing lines a LOT faster though!

Re: Speed

I have gotten the following code down to a benchmark value of 2314 ms from the original of 7020ms. Thats under a third of the original speed. That has involved the hardcoding of the pins used however. And the use of digitalWriteFast2, plus some inlining of the SPI code. I have edited FTOLED.h a bit ...

Re: Speed

Just found something that doubles the speed of some of the operations.

Re: Speed

Ooo thanks for the speedy reply! I have already attacked the stripchart sketch and removed all unneccessary code down to basically measuring and drawing one analog channel only. Its nice and fast until you get a big signal on the analog line, and the extra pixels being drawn significantly slow down ...

Speed

Is there a datasheet to the actual controller for this device? I would like to get faster line drawing code, i actually want to play with 3d objects and the accelerometer module for some cool stuff heh. And when using the "secondary" connections, is that hardware SPI? or software. There is a MCU run...

Allegro Current Sensors

Very usefull!

The allegro company has a whole bunch of hall effect current sensors. Having one of those in the 100amp range would be useful, as well as 5-20 amps.

Re: stackable I2C motor shields/brushed DC servo driver

Like you mentioned your most serious problem is noise. Electric motors, especially brushed ones, can cause serious noise in circuits. The other problem is random currents floating around your earth and power. I do know what you mean though, be able to physically stack them, and address them by speci...

Re: RTC Module wtih DMD

Hi Ben, thats the kind of thing the arduino was designed for.

What my procedure would be:

First, create a sketch to simply set and display the sign.
Then, create a sketch to display text of your own on the DMD.
The merge the two :)
Thats how i learned how to program the arduino haha
