Teensyduino 1.49 Beta #1

Paul · Dec 1, 2019

Here is a first beta test for Teensyduino 1.49.

USB optimization is the major change in this beta. I hope you'll have a moment to give the new optimized USB serial a try. I will soon start using this new optimized USB code as the basis for the many other USB types...

EDIT: links removed, please use 1.49-beta3

Changes since Teensyduino 1.48

Optimize USB serial on Teensy 4.0
Move USB serial buffers from ITCM to OCRAM on Teensy 4.0
Fix stalled USB serial transmit if multiple of 64 bytes on Teensy 4.0
Support different USB descriptors for 12 vs 480 speed on Teensy 4.0
Add FLASHMEM keyword
Arduino memory usage for Teensy 4.0 shows only RAM1 (512K) bank usage
Fix Audio lib delay effect maximum (2.4 sec) on Teensy 4.0
Fix missing ITCM padding from Teensy 4.0 memory usage
Fix empty code on Teensy 3.x if yield() overridden and no core lib functions used

Seems fine, even running the usb virtual serial as fast as possible (Linux).

MichaelMeissner · Dec 1, 2019

It would be nice if you can pull in the fix for teensy4/imrxt.h and the WS2812Serial library from KurtE to get WS2812Serial to work on the Teensy 4.0:

Installed 1.49b1 over github cores on 1.8.10 : All seems good and well.

Improved USB Serial Receive code working fine.

RAM report looks different and about right - showing cross ref of KurtE/'Frank B' imxrt-size.exe:

Code:

Sketch uses 33440 bytes (1%) of program storage space. Maximum is 2031616 bytes.
Global variables use 45748 bytes (8%) of dynamic memory, leaving 478540 bytes for local variables. Maximum is 524288 bytes.

Installed on Windows10x64 with no problems.

Ran a couple simple usb serial tests.
Test 1 dumped three floats to the sermon with no delays in loop and it kept up with no issue.
Test 2: Used SerialPlotter to plot those same 3 numbers - basically hung the ide so I had to use task manager to kill the process.
Test 3: Retested SerialPlotter with a delayMicroseconds(100); in the loop. SerialPLottter kept up no problem.
Test 4: Ran @defragsters string print sketch from the other thread with a couple of various length strings:

Code:

000  | #=564

Test 4: Multiple sends of 564 length string. (a) if I send slowly seems to work (tested with 15 sends), (b) if I send it repeatedly it seems to hang the Teensy and loose the port. (c) if I send multiple lengths strings of 451 seems to be no problem - couple of times I sent 901 length one and it didn't have a problem as long as I went back to 451 length string. Think I need to automate the process instead of fact fingering it.

EDIT: I would agree with Michael that it would be good if you could pull in the core PRs. Have to go back and put them back in again now.

@Paul - great to see the USB stuff being updated! Trying to decide if there are enough people beating up on this and wait...

For now I may simple install fresh copy of Arduino 1.8.10 into new directory and do an install of this beta over it.

PaulStoffregen · Dec 2, 2019

Right now I'm working on support for MacOS Catalina. If there problems with the new USB serial, really hoping for test cases.

Will look at the USB stuff and merging things in a couple days, and then publish another beta... maybe even with a new Mac build...

dukeblue219 · Dec 2, 2019

Great news about the USB. I'll check it out as soon as I can and see if the occasional stall has been fixed.

Fix Audio lib delay effect maximum (2.4 sec) on Teensy 4.0

So does the t4 allow longer then 2.4 sec delay?

el_supremo · Dec 2, 2019

The code in 1.49 B1 of effect_delay.h is:

Code:

#if defined(__IMXRT1062__)
  // 2.41 second maximum on Teensy 4.0
  #define DELAY_QUEUE_SIZE  (106496 / AUDIO_BLOCK_SAMPLES)
#elif defined(__MK66FX1M0__)
  // 2.41 second maximum on Teensy 3.6
  #define DELAY_QUEUE_SIZE  (106496 / AUDIO_BLOCK_SAMPLES)
#elif defined(__MK64FX512__)
  // 1.67 second maximum on Teensy 3.5
  #define DELAY_QUEUE_SIZE  (73728 / AUDIO_BLOCK_SAMPLES)
#elif defined(__MK20DX256__)
  // 0.45 second maximum on Teensy 3.1 & 3.2
  #define DELAY_QUEUE_SIZE  (19826 / AUDIO_BLOCK_SAMPLES)
#else
  // 0.14 second maximum on Teensy 3.0
  #define DELAY_QUEUE_SIZE  (6144 / AUDIO_BLOCK_SAMPLES)
#endif

which sets the delay queue length to the same size as in T3.6 (2.41 secs). In the previous version (TD 1.48), there was no #ifdef test for the T4.
I changed DELAY_QUEUE_SIZE to (220500 / AUDIO_BLOCK_SAMPLES) and then in the delay example sketch I increased AudioMemory to 1723. This allows me to extend the delayed time of the "bell" up to 5 seconds. With these values, OCRAM usage is:

Code:

OCRAM: 460896 B	(87.91% of  512 KB)

In principle, you could extend the (mono) delay to about 5.8 seconds but that would use all the OCRAM and might prevent your program loading

Thanks for clarifying that for me pete.

This beta doesn't add support for USB keyboard on teensy 4.0 right? If not, is there any updated time estimate for this?

I saw github CORES has first pass of T4 USB Keyboard checked in followed by mouse and joystick - likely out with Beta 2 when it is ready:

Code:

Add USB keyboard for Teensy 4.0 

Add USB mouse & joystick for Teensy 4.0

PaulStoffregen · Dec 9, 2019

Yes, I did the HID ones and I'm working on MIDI now. I did a few quick tests on keyboard, mouse and joystick. Touchscreen still needs more work.

My plan is for 1.49-beta2 within the next few days.

Planning to merge Kurt's work on WS2812Serial, and maybe some other stuff. Now's the time to remind me of stuff that should be merged for 1.49-beta2.

I want to finalize 1.49 before the end of 2019. So this week is probably the last opportunity for new features to get into 1.49.

KurtE · Dec 9, 2019

@PaulStoffregen...

Sounds great.

There were a few other PR's out in special thread, like fixing some issues for Wire. @mjs513 has a nice version of the ST7735_t3 code base...

Wondering about things like ADC library? Currently for T4 we have been hacking on our own version that I am calling ADCL_t4... But it is starting to get more complete. Not sure what to do with libraries like this (ADC) again where owners are no longer active.

KurtE · Dec 9, 2019

@Paul was wondering about possible additions to IMXRT.h. That I have run into as part of the ADC port to T4 Things like:

ADC structure definition:
Which I currently have in the ADCL_t4 library: (https://github.com/KurtE/ADCL_t4)

Code:

typedef struct {
    volatile uint32_t HC0;
    volatile uint32_t HC1;
    volatile uint32_t HC2;
    volatile uint32_t HC3;
    volatile uint32_t HC4;
    volatile uint32_t HC5;
    volatile uint32_t HC6;
    volatile uint32_t HC7;
    volatile uint32_t HS; 
    volatile uint32_t R0; 
    volatile uint32_t R1; 
    volatile uint32_t R2; 
    volatile uint32_t R3; 
    volatile uint32_t R4; 
    volatile uint32_t R5; 
    volatile uint32_t R6; 
    volatile uint32_t R7; 
    volatile uint32_t CFG;
    volatile uint32_t GC; 
    volatile uint32_t GS; 
    volatile uint32_t CV; 
    volatile uint32_t OFS;
    volatile uint32_t CAL;
} IMXRT_ADCS_t;

#define IMXRT_ADC1S         (*(IMXRT_ADCS_t *)0x400C4000)
#define IMXRT_ADC2S         (*(IMXRT_ADCS_t *)0x400C8000)

Also looking into how to use Timed DMA reads as part of our ADC port. With PIT timer and DMA and XBAR to ADC_ETC...
Was finding in example app using magic numbers iwth XBAR mapping. So I hacked up a #define line as part of this, out of the PDF file ...

Are these things we should add to imxrt.h?

I can do, and issue PR if that makes sense...

I'm not quite sure either....

Yes, please do.

But do not delete the already defined full register names. Convert them to the new struct. I believe there's at least one pull request still pending which I haven't merged because it deletes the original register names. I'll go back and look at it and others again, after I get USB MIDI working.

Will do.

I for sure would not delete the old defines. Have two choices, both ways are in imxrt.h.

That is could redefine all them as reflecting the new structure: like with I2C...

Code:

} IMXRT_LPI2C_t;
#define IMXRT_LPI2C1		(*(IMXRT_LPI2C_t *)0x403F0000)
#define LPI2C1_VERID			(IMXRT_LPI2C1.VERID)
#define LPI2C1_PARAM			(IMXRT_LPI2C1.PARAM)
#define LPI2C1_MCR			(IMXRT_LPI2C1.MCR)
#define LPI2C1_MSR			(IMXRT_LPI2C1.MSR)
#define LPI2C1_MIER			(IMXRT_LPI2C1.MIER)

Or others just left in the old offset way like:

Code:

#define IMXRT_FLEXIO1_S         (*(IMXRT_FLEXIO_t *)0x401AC000)
#define IMXRT_FLEXIO2_S         (*(IMXRT_FLEXIO_t *)0x401B0000)
#define IMXRT_FLEXIO3_S         (*(IMXRT_FLEXIO_t *)0x42020000)

#define IMXRT_FLEXIO1		(*(IMXRT_REGISTER32_t *)0x401AC000)
#define IMXRT_FLEXIO1_b		(*(IMXRT_REGISTER32_t *)0x401AC400)
#define FLEXIO1_VERID			(IMXRT_FLEXIO1.offset000)
#define FLEXIO1_PARAM			(IMXRT_FLEXIO1.offset004)
#define FLEXIO1_CTRL			(IMXRT_FLEXIO1.offset008)
#define FLEXIO1_PIN			(IMXRT_FLEXIO1.offset00C)
#define FLEXIO1_SHIFTSTAT		(IMXRT_FLEXIO1.offset010)
#define FLEXIO1_SHIFTERR		(IMXRT_FLEXIO1.offset014)

Preference. Obviously just leaving the old defines is simpler (and maybe safer), but the using the structure does look cleaner...

Yes, this.

The other ones with a dedicated struct typedef has (mostly) been done that way.

Eventually we'll probably get rid of all the old offset stuff. I did that before the beta test because it was much faster and easier to compare with the tables in NXP's reference manual. Even then it took over a week to make the first header file with all the registers.

KurtE · Dec 9, 2019

Ok I edited it like you mentioned...

You might want to take a look, to make sure I did not screw up something.

Paul I think you are referring to the PR I did for the Encoder registers. Based on your preference I will redo the structure and ensure it retains the original register names. May have to do a little work on the lib but not too bad. Will use what Kurt did for ADC as the model.

EDIT: PR Updated.

@PaulStoffregen... Sounds great.

There were a few other PR's out in special thread, like fixing some issues for Wire. @mjs513 has a nice version of the ST7735_t3 code base...

Wondering about things like ADC library? Currently for T4 we have been hacking on our own version that I am calling ADCL_t4... But it is starting to get more complete. Not sure what to do with libraries like this (ADC) again where owners are no longer active.

If we are going to update ST7735_T3 from mjs513's new changes, would it be possible to add the two uncanny eyes examples that mjs513 had in his tree to the Teensy version? I believe KurtE, and defragster worked on it (maybe I had changes in that as well)? Given that the developer has essentially moved on to the newer Adafruit M4 boards with a whole new source base, it would be useful to have both T3.x and T4 versions for people to use.

Paul - this millis() issues on certain set_arm_clock transitions. See: pjrc.com/threads/58053-T4-set_arm_clock-and-micros()

Title says micros() but that is because it tracks on millis() clocking.

Yes. Please send a pull request. Will probably be in 1.49-beta3, since I'm about to package up beta2...
