Example:
// Release data pins by putting them back to input
static inline void releaseData() {
GPIO6_GDIR &= ~0x00FF0000; //Set the 8 Data pins of GPIO6-16 to GPIO6-23 as input (note the invert ~)
}
Cards that are 32GB or smaller are formatted with FAT32 and typically have the VFAT support on top of FAT32 (VFAT adds support for names other than the 8+3 uppercase).
Cards that are 64GB or larger are formatted with ExFat.
Hi @Neurofrantic - this is very sensible advice, and $120 USD is a small amount to pay for this. I have worked with the Eclipse IDE and the STM32 framework over the last few years, and I liked the insight the 'MX' tool gave to programming...
If you're working with the IMXRT1062 at this level, you might want to consider purchasing an NXP development kit and setting up the MCUXpresso environment for checking it out. It's not a Teensy with Teensyduino of course. But it's a powerful way...
Teensy LC to T4.1 is ok, they are both 3.3V.
For nano to Teensy LC or 4.1 use an Adum1201 for level shifting (5V to 3.3V). The Adum1201 is designed for Serial Comms level shifting.
It is possible to buy ready made Adum1201 modules. See here and here.
Below is a connection diagram for you.
What follows is an explanation of connections:
VDD refers to the voltage level for a side be it side 1 (A) or side 2 (B).
In the diagram below Side 1 (A) has been chosen for the Teensy and Side 2 (B) for the...
VINIA has 8 channels, each one can be independently configured as a sample player, full synth voice, drum synth, harmonic oscillator, chord generator... or as a multi-effects unit for external audio processing.
Easy to use constructor allows...
