I have implemented the code to use interrupts, but not tested it yet, as I have not received the ATmega4809 yet, and the board I am using as slave uses 5v.
But I was thinking, maybe it would make more sense using...
Thank you for your insights, Frank. I had indeed thought about using interrupts, but I have read the documentation about interrupts in the Audio library, I am still not sure how/if adding more interrupts while I am...
I am creating an audio sampler/sequencer with Teensy 4.1 and I am running out of pins, so instead continuing adding multiplexers, I have thought about using an inexpensive ATMEGA4809 (the Arduino Every microchip) to...
Very good news it has already being proven to play audio with LittleFS. I am curious about how the read speed would perform for NAND chips over QSPI in comparison with the current NOR over SPI. AFAIK QSPI should...
Unfortunately I am not using a display with touch screen, so I cannot check it :(
Thank you, KurtE. So, if I understand correctly, for example what the different pins marked as CS0 means that all they are...
The pin 10 is marked as a CS0 pin, so maybe that means you can use any digital pin as CS (at least with the ILI9341_t3n lib)?
And the same for the DC pin?
Hi. I am trying to figure out what are the available alternate SPI pins for this two devices, using the Teensy 4.1.
ILI9341 Display
I am using the ILI9341_t3n lib, but I think my doubt apply equally when using the...
In the GUI Audio design tool, the output I2S object lists:
Compatible DAC Chips:
PCM5102A
PCM1808
PCM5242
CS4344
The PCM1808 should be listed as a compatible ADC chip in the input I2S object instead.
I disagree that Arduino is a good IDE for beginners, at least in what respect to the editor. The lacking of complex features can have some advantages for a beginner, but in my opinion things like autocompletion, error...
Hi.
I have a ILI9341 module connected to a Teensy 4.1. I have followed the instructions here. But, as I am not using neither the touch capability nor the SD card of the module, I have thought I could liberate one pin...
Thank you defragster, I missed that link to the sketch. In case anyone is interested, I have run the CoreMark sketch on the Teensy 4.0 and the Teensy 3.6 at different speeds and these are the results:
Wow, it looks that stepping down to 528 MHz would considerably increase the its lifespan. That joined to the lower power consumption makes me consider stepping down to 528 MHz. How remarkable would the performance...
