Hello. I've testing Frank Boesing's Arduino-Teensy-Codec-lib with Gameduino 2 modified library for Teensy 3.5/3.6 and SDIO, I find that modifying this lines in the mp3 library file in codecs.h: line 81: bool fopen(const char *filename) {ftype=codec_file; /*AudioStartUsingSPI();*/ fptr=NULL...

Thank you! I've searched other sources using teensy as https://courses.cs.washington.edu/courses/cse466/15au/Calendar.html

I need to coordinate access to Sd card data using SDIO inteface to send jpeg image data to a FT813 screen at max possible speed using SPI interface and while load audio sample data to send to the teensy audio shield trying to go all in sync. Because advanced use of hw resources by the supporting...

I'm interested in get the juice from the teensy 3.2/3.5/3.6 using multitasking like environment. I've learning about interrupts,dma,timers but there are fuzzy limit between libraries and how they allocate resources without conflicts accesing to it. There are plans to unify teensy libraries that...

Help how to use Teensy 3.x with external 3.3v 5A Switching Power Supply I've planned to use Teensy 3.2/3.5/3.6 with FT813 7" Riverdi screen which needs 3.3v 500mA power. How I can power both the teensy and the lcd screen with the 3.3v switching power supply? https://goo.gl/images/bSUlVx
