    Never got one of those 7789's - found a 7735 but size is off. ILI9341's galore ...

    And for a display? showing #include <ST7735_t3.h> // Hardware-specific library #include <ST7789_t3.h> #include <SPI.h> #include <SD.h> #define TFT_DC 1 #define TFT_CS 5

    @mjs513 - is this just plugged in without alteration to the ML Carrier for voltage as Paul may have done?

    Assuming this is a T_4.x from context and 912 MHz speed? And no idea how much soldering and other added thermal mass attached. On T_3.6 and prior Teensy the CPU speed was derived from common clocks and changing...

    On a 'good' day "unlimited" power is nice :( > Sounds like your attention will be good for having it made right, as usual.

    Suppose SFun ATP docs would show the circuit for their USB-C and power to the board and HOST connect. Maybe too much for a quick/simple board - but it would be nice to have that power - especially with display and HOST...

    Thanks for that. Busy morning here - the PJRC Carrier board looks good. Having USB-C would be okay - or better. Assuming using that connector is how the SFun ATP board presents more power to the board? Using...

    Yes, like before in the other thread for the outputs: for (int i = NB_PADS; i < NB_PADS+NB_PADS; i++) { But - using analogWrite ... with those correct offsets ... should be more direct with hardware support...

    @Jibeji - you made a new thread I see ... T_3.2 has PWM driven Analog pins. I just wrote this on a T_4.1 for A9 or pin 23 the T_3.2 has as well. void setup() { Serial.begin(115200); while (!Serial && millis()...

    Indeed the T_3.6 was potent at 256 MHz - @BrTaylor can fill more details - seems the IMU cycle was 500Hz with what he was doing years back - and reading GPS strings in addition to the 9DOF IMU - and sending all data off...

    Great that was an easy solution for the situation to get your system in spec and ready to ship and install.

    Minor edit to LFSIntegrity to HALT on failed myfs.begin() :: github.com/PaulStoffregen/LittleFS/pull/11 - just got two T_4.1's mixed up and failed to catch the passing NAND and NOR fail notice on QSPI

    @brtaylor might have some real world flying Teensy experience? The T_4.1 bottom QSPI pads can hold PSRAM'S - not static enough perhaps. > how much space is needed? > how many bytes/sec to write? Asking because...
