Title: ESP32 + FT232H in 245 fifo mode
Post by: amadeok on March 03, 2021, 08:06:19 PM
Hello
I'm working on a project that uses an eink controller board that has a esp32. The aim is to make the board mirror the pc screen and make a sort of pc monitor. I'm already achieving this by transferring the image data from the pc to the board using wifi, but i'd like to use a FT232H in 245 8 bit parallel synchronous mode to make the transfer faster. The display has eight data pins (D0 to D7) and a CLK signal that can be 60MHz. I'd like to connect the data pins and the clock line of the FT232H directly to the ones in the display, and then connect RXF, TXE, RD, WR and OE to the gpio pins on the ESP32, in this way:

The other signals required to drive the display would still be controlled by the esp32, the ft232h would only have the job of transferring the data.
Is this feasible?
thanks

Hello,

This is something that you can test and evaluate using our development module for example:

https://ftdichip.com/products/um232h/ (https://ftdichip.com/products/um232h/)

You can read more about 245 FIFO mode in:

TN_167 FTDI FIFO Basics  (https://ftdichip.com/wp-content/uploads/2020/08/TN_167_FIFO_Basics.pdf)

This is not something that we've specifically came across before but maybe there are other FTDI Community users who have done something similar.

Best Regards,
