DIY USB 3.0 Camera: UVC Video Device Class VGA Camera Using Cypress FX3

This Project is going to next in the series of previous projects. Previously i interfaced inexpensive OV7670 VGA Camera to MCU.

In this post we will overcome the 10FPS limit of frame rate caused by slow Parallel port of PIC32MZ. This version of Camera will use 4.8Gbps Cypress FX3 USB 3.0  controller, with use of this controller comes 32bit 100Mhz GPIF interface, which make it possible to easily implement 30 FPS 640x480 live video transfer. 

Capability of Cypress FX3 is way higher than VGA 30FPS, but for this test project i will be limited the by the max resolution of OV7670. 

Marconi 2024 RF Signal Generator LCD Display Repair

This is going to addition to my previous Marconi 2024 Error 508 repair . I have recent bought my self a broken Marconi 2024 which has many issues, few issues i fixed in previous repair post now in this post i will show you how i replaced the LCD.

As many other people have pointed out controller of the LCD fitted in Marconi is compatable to RA6963,T6963 Controller so i search around on web and found ERM24064DNS-1 .

The LCD display we are replacing had VFD back-light but replacement LCD has LED back-light. so i need to take out VFD power supply and bypass with for 5V LED power supply.

Here is how VFD power supply is removed and bypassed, 5V is supplied by the board Display also needs 5V.

Replacement LCD Display size is exactly same but PCB size is small so mounting screw are different location. and Display thickness is also less with new Display.
