Just flashing with teensy_loader_cli seems a lot easier than to have the build environment of MicroPython for Teensy.
Ok, after some incompatibilities between ARM toolchain from Arduino/Teensyduino and MicroPython, I've succeded with the GNU ARM Embedded Toolchain.
Here are the MicroPython 1.8.6 firmware from dhylands's dev-build for :
* Teensy 3.1/3.2;
* Teensy 3.5;
* Teensy 3.6.
Some benchmarks and comparisons with Teensy 3.2, 3.5, 3.6 and other MicroPython boards :
Free RAM on MicroPython boards
Benchmark comparison of MicroPython boards
ADC performance of MicroPython boards
The Teensy 3.x 16 bits ADC has different speed with respect resolution, e.g., on Teensy 3.6, in ksamples/s :
- 13, 14, 15, 16 bits :106;
- 11, 12 bits : 148;
- 9, 10 bits : 153.
- 8 bits: 158.
So Teensy 3.6 is the fastest MicroPython board for MicroPython/calculations processing and for ADC reading inside a loop.
Thanks, dhylands, MicroPython for Teensy 3.x is already very useful (for reading sensors, datalogging, etc), despite not being complete (no time, DAC, etc modules).
