I was wondering if the f407 can support vga monitors or if that was too much for the processor to handle? |

This is something I 've been wondering about, as the CMM2 uses an on-chip hardware LCD driver module that's hacked to give VGA. However, that also has plenty of fast RAM for a frame buffer. The PicoMite does it by using a PIO and DMA to get the necessary speed. I'm not sure whether it's possible on the F4. Not at the moment anyway.

No:The F429 chip is the lowest with the requisite H/W support |

Kind of can (do some web reading), but not have MMBasic as well. MMBasic on PIC32 uses that chip's excellent DMA & I/O; the RPi Pico has PIO (etc). F407 can use its DMA but just not as great for this. (Then the F429 etc have internal powerful hardware.) Don't overlook ST's NUCLEO boards - very good value. John Edited 2023-09-08 04:58 by JohnS |
