Today’s microcontrollers are high-speed power units that can do absolutely wonderful things. With fast clock speeds and special DMA hardware, it is usually possible to achieve great feats that seem almost absurd on the surface. [Bitluni] Decided to prove it, Run six (6!) VGA monitors from a single ESP32. (Video, embedded below.)
ESP32 runs at a maximum speed of 240 MHz. It also has some beautiful DMA hardware and GPIO mapping, making it ideal for this task. [Bitluni] It can therefore be set up to drive up to six VGA displays with one-bit monochrome output per pixel. Or, by combining six output pins into two groups, three in each group, he can run two 3-bit color VGA monitors.In both cases, the resolution is an impressive 640 x 400, and [Bitluni] Demonstrate the hardware by driving six projectors with a starry sky display.
is that useful? Maybe not yet, but there are definitely some applications we can think of. Share your own thoughts in the comments.In the meantime, please check [Bitluni]Other great works of ESP32.
