It is possible! Use D0-D7 and resolder the Resistor R4 to the position R5. D8-15 can be unconnected http://www.raspberrypi.org/forums/viewtopic.php?f=64&t=33679&hilit=controller&start=100 Post #3 I have tried this and it works.

Dear Paul, 1.20 Release Candidate #1 #define FTM_CONF_BDMMODE (((n) & 3) << 6) // Behavior when in debug mode #define FTM_CONF_NUMTOF (((n) & 31) << 0) // ratio of counter overflows must be #define FTM_CONF_BDMMODE(n) (((n) & 3) << 6) // Behavior when in debug mode #define...

Thanks Paul! New Version. Needs Teensyduino 1.20! No need for additional register definition file. The new 1.20 kinetis.h has all register included. Barney

Dear Paul, do you have a time line, when will you have the latest Arduino IDE 1.5.x. Barney

Thanks Paul :)

Here another test with ISR:

This Code works for some test:

Dear PaulStoffregen, i want to bring me with this again in memory. http://forum.pjrc.com/threads/25044-Teensy-3-1-PWM-for-BLDC?p=42155&viewfull=1#post42155 http://forum.pjrc.com/threads/25044-Teensy-3-1-PWM-for-BLDC?p=42191&viewfull=1#post42191 i think this is ideal for the release Teensyduino...

Thank you to all involved, it was a problem from the pocket oscilloscope UNI-T UT81B. After Paul has created the video, I used my second oscilloscope. There is no jumping of the signal! Everything is fine. Except for my pocket oscilloscope ... Thank you Barney

void loop() { for(pos = UntererStellWertMotor; pos < ObererStellWertMotor; pos += 10) { // von 1ms to 2ms analogWrite(Pin_Motorstelleranschluss, pos); // Geschwindigkeitsvorgabe Motor delay(100); // waits 15ms for the servo to reach the position...

Hi Whollender, i don't see 1,21,41 i see instead 1,30,20,50,30,... next day i will test your suggestion with longer delay.

Hi Paul, no idea? Barney

Dear Paul, please test this Code and use an Ozilloscope. You can see the PWM doesnt increased the value straight. The PWM hops back and forward in little steps. Is there an Teensy register bug? I have tested different resolution but with the same effect. Barney #define...

Dear PaulStoffregen can you include (some emelents or whole) from this kinetis_ftm.h file or put in in your hardware tensy tree? http://sourceforge.net/p/nuttx/git/ci/ddb019413f39bbe495dba2a55c60f9ff8f8e00ce/tree/nuttx/arch/arm/src/kinetis/kinetis_ftm.h#l355 I am missing the above additional...

I have found an example code for an three phase PWM with dead time. So i have solved my problem. #define FTM0_CLK_PRESCALE 0 //no prescale #define FTM0_OVERFLOW_FREQUENCY (80000) // 80kHz #define FTM_QDCTRL_QUADEN (1 << 0) // Bit 0: Quadrature Decoder Mode Enable #define...

Final view for B side

Here two version in one document: What do you mean, lines or grey out?

Hi Nantonos, i see this glichtes under Windows not with Linux or Smartphone. Ich have tried different test: 1. PDF creation with version 1.3, 1.4 , 1.5 -> glitches exisits 2. Other fonts -> glitches exisits 3. Make pdf with Linux (Ubuntu) -> glitches exisits 4. Print out on Color Laser...

Hi Stevech, Hi Nantonos thanks for your suggestions and information. I have changed MOSI and MISO to the right position. In the wikipedia page i have found that CS are named SS. So i have changed CS to SS. Other correction or suggestions? Barney

I think there are some Pins to delete like TX/RX Pin 3/4 or DOUT/DIN Pin 7/8 I hope my additions are correct Scribus File

I am confused, on http://www.pjrc.com/teensy/td_libs_SPI.html i think MOSI and MISO is in wrong order Please take a look on http://www.freescale.com/files/capture/pdf/mk20dx128vlh7_lqfp64.pdf

First Try! Dont use for development.

Hi, it is possible to get tho original file for this pdf "https://www.pjrc.com/teensy/card5a_rev5.pdf"? I want to insert additional Information about the PWM FTM0 channel pin assignment.

Hi Tim, you are right. But it isn't wrong write death time. If you set the time wrong the MOSFETs are death :) thanks for the correction. Barney

Excuse my bad English! Hardware independent? I think it isn't possible. An three phase PWM must be near at Hardware as possible to protect the computation ressources of the mircocontroller. I have take a look to the datasheet of the microcontroller. The register set isn't ease to understand for...

I dont need such complex settings for my BLDC! Setup parameters: * set PWM resolution * set up high and low driver function * set dead time (to protect the MOSFETs) * set period time * synchronized the clock of the tree channels the main controll parameter -> controll the duty cycle

Your modification is very fast. You activate the 8 byte buffer. I use the 24MHz clock setting. Thanks for your help

Hi, on Arduino DUE ist was possible to set the SPI speed to clk/2, on Teensy 3.1 there is no way to controll the SPI speed like Arduino DUE. Why? Is there an simple way to overwrite the SPI clock settings like in this code snipped? From the Adafruit_ST7735.cpp #ifdef __AVR__...

Hi, for an own BLDC controller i need tree PWMs with an high an low driver. I have found some functional code for an Arduino DUE: Here an smal example: //Konfiguration der PWM-Kanäle 0 bis 2 (u,v,w) (left-aligned, enable dead time generator) for (int ch=0; ch<3; ch++) {...
