There are several ways to do it.
With out flickering:
1) You can use the frame buffer.
With this you could erase the whole screen, draw everything and then do an updateScreen() call which will then do a redraw of...
Sorry, I probably have not used Atmel Studio in probably a decade, so I have no idea and I am guessing that is true of lots of others that are up here.

Yes you can use those other pins for GPIO stuff.
From my Excel document on T4.x I have the page:

Sorry not sure what is going on. But maybe some additional information might help.
What exactly are you running? Are you running the Teensy example USBtoSerial? any changes at all to the code?
Which IDE are you...
I again should mention that it is unclear if these changes will ever be pulled in. Most of the stuff was done about a year and a half ago. But keeping fingers crossed.
The 4 files I changed are shown in the one...
Each teensy type has a different number of EEPROM locations, as you can see on the page:
https://www.pjrc.com/teensy/td_libs_EEPROM.html
Teensy 4.0 1080 bytes
If for example you write to location 1010, The system...
Here is a sort of quick and dirty sketch to print out mapping...
uint32_t *port_regsp = {(uint32_t*)&IMXRT_GPIO6, (uint32_t*)&IMXRT_GPIO7, (uint32_t*)&IMXRT_GPIO8, (uint32_t*)&IMXRT_GPIO9};
uint8_t pin_numbers;
...
Yes you can read in multiple pins at the same time. Typically after startup all of the pins will be on GPIO ports 6-9
So you could read in all of the pins on port 6 using either:
uint32_t port6_val = GPIO6_PSR;
or...
Me too.
In most cases like this, I would recommend that you probably also post up on the Arduino forum as well. https://forum.arduino.cc/c/software/ide-2-x/93/l/latest
