If using two UART pin sets, each/all UARTS have unique individually settable baud rate.

Not noted how much data comes in on each stream?

First guess: Alternating between the two each at 10Hz...

Doh - didn't see the single quotes on the 'ZERO'

Is the the switch 'VAR' a byte type by any chance?

Or something odd confusing the compiler optimization?

switch ( VAR&0xF )

I saw some hangs leaving Vid mode as well in some combination with ILI9341 - thought it was just an invalid command series but it was there. Some part of the DMA left active doing interrupt spasms?

@mjs513 does the "case 0x30:" work as "case 48:" ?

I've got outdoor things to do as well. Spring sun is sprouting trees in deck cracks and a pickup firewood to unload.

Saw the PR to mjs513 was taken -testing:

//#define USE_SPARKFUN 1:

"d" :: (before FlexIO)...

Good luck @KurtE.

Will keep using the ILI9341 then perhaps swap to the ST7789 when your new work is done.

Not sure what is up with 'z' - it can work - but sometimes just aborts it seems.

@mjs513 - Noticed the SFun display backlight was on during Pin Testing when it should have been off. Nice the single Teensy lib works and not a pile of others needed.

"F" seems to be working in CallBack w/code like DMA

Last run of DMA was torn down left edge after it centered instead of the top?

Seems I got that in testv3.

@mjs513 - Paul has a PR pending on your git.

... here a short time - github desktop not showing me changes ... another remove/and fork ... arrgh

Still seeing this ugly (hard coded static)...

Created /mjs513/TMM-HB01B0-Camera/pull/10 for adding hm01b0_testv3.ino for posts noted above

next guess would be to comment the actual SD file I/O - without that it is nothing and would point to TThreads getting bored with nothing to do between the loop delay and the .yield

That is short and sweet - out of runtime to repro now ... not even a second task doing anything - except loop just burning cycles in a delay

With the print of "Success save 1" the first SD write...

Edited above - can't find explicit post, but that seems to have been implied in a Paul post I found versus faulty memory here.

Without the code as noted the needed detail is in the part not shown.

Yes, that is the nature of interrupts. Execution returns to the point and state of the interruption.

Seems to be a typically good exposition - Makes sense to me and I haven't even looked in any of those rabbit holes.

Not sure about the priority level of SPI interrupts. General interrupts get set to 'mid level' of #128 and can raised (lower number) or lowered and the number blocks jump by 16 { i.e. 0-15 is the...

What 'trouble'? Only change is to add 'F'?

That is a big bunch of data - 300 consecutive 512 byte buffers. Though at 100-200 Mbs throughput that ~1.3M bits should be a blink. Though we've seen PC side using Java isn't a perfect conduit.
