5: Globe Test PCB

Before investing too much time and money in designing the full Globe PCB a smaller test board was needed. The purpose of this PCB was to test the following: TFP401 interface with FPGA SDRAM interface with FPGA Modifying EDIDs FPGA SPI controller & interface with TLC5951 First version of code The board was designed as a …

4: Globe PCB design

POV MKI used 4 PIC32s each controlling 4 TLC5951 LED drivers which each in turn drive 8 RGB LEDs, with one of the PICs acting as master and the other three as slaves. Since we are only increasing the number of LEDs, LED drivers and required SPI control lines, we can either apply more microcontrollers to …

1: Introduction

This blog has been written for those who are interested in the development of Globe and the design behind it. I have tried to keep the engineering terms to a minimum leaving it accessible to all, but if you do come across something that you don’t understand please do write a comment and I will …
