Hello all
Bit the bullet and got a couple of Teensys, so need to get a few newbie questions answered.
First up, I need to drive a '595 shift register, it MUST be at 5V, I'm using a T3.6 therefore 3.3V, was thinking to use a level converter, can 5V be tapped off from anywhere? Will be using USB power so am thinking VUSB pin outputs 5V? Is there a more preferred/better way of doing level shifting on a 3.6?
Second, got an ILI9341 320x240 2.8" touch TFT Display, what value resistor to use with for the backlight please? Again this will be with the T3.6. Is the backlight powered from 3.3V?
Related to the above, is there any example code that will display a graphic (BMP, JPG) stored on the T3.6 SD card?
Hopefully these are easy to answer questions for those with prior experience.
Thanks in advance.
