      PaulS replied to the thread MODBUS TCP.
      That's interesting, you are writing value 1000 to AOx but you are reading back value 2000 from AOx. You may want to try the other use of the modbusTCPClient.holdingRegisterWrite() command. Instead of boolean writeSuccess =...

      PaulS replied to the thread EtherCat on Teensy 4.1?.
      Getting the hardware integrated on your board is probably the easy part, the coding is the part that is harder to accomplish. You still may want purchase the shield as a reference for the person is doing the actual coding... Paul

      PaulS replied to the thread EtherCat on Teensy 4.1?.
      Had a quick look at the EasyCAT shield and related library. The shield uses a Microchip LAN9252 EtherCAT device controller, not a 'standard' Ethernet controller. I assume that the LAN9252 chip probably takes care of the EtherCAT protocol...

      Too bad that we don't have LDF file for the HVH50. Saw your request for info at the peak-system forum as well... I agree. Frames { HV_He_01: 28, Controller, 4 { KL_HV_PTC_soll, 0 ; KL_PTC_ein, 8 ; } This tells me that the bit...

      The short and simple answer is you should uninstall or delete SdFat you've installed, so Arduino IDE will use the copy of SdFat which comes with Teensyduino. When you install a library, usually Arduino IDE gives your installed copy priority...

      Yes, this problem usually happens on Windows if Teensy Loader is still running when uninstalling the older Teensy files or using an older IDE. Windows does not allow the EXE file to be deleted. Arduino IDE does not handle the situation well...

      Additional info: with Teensyduino 1.58.2, the sketch from message #6 runs fine on both Teensy 4.0 and Teensy 3.2. I tried with 2 versions of FastLED: 3.4.0 and 3.6.0, same results. Paul

      Probably the Teensy 4.1 can change pins faster than the 74HC595 can handle. Teensy 4.1 is way faster than a Teensy LC. Sprinkle a number of delay(1);'s in the updateShiftRegisters() function like so: void updateShiftRegisters() {...

      PaulS replied to the thread Simple audio sine signal generator.
      Yes, your design will do. Set the sine module output to 1.0 and set the attenuation or amplification at the amp module. Paul

      Pff, too many variants of ESP32 boards around. Also chip pin numbers != board pin numbers != GPIO numbers. Look at the pinout. Found this in the datasheet of the chip: You would have to use board pin numbers 16 & 17 [GPIO16 & GPIO 17]. This...

    • PaulS
      It looks like you have this board. Problem is that the TX & RX signals of the ESP32 chip connect to [1] the external TX & RX board pins and to [2] the onboard "USB-to-UART Bridge". So you are using the same serial port for Teensy communication...

      PaulS reacted to BriComp's post in the thread GPS not working with Teensy 4.1 with Like Like.
      On Teensy pin 0 is RX and pin 1 is TX. If you have them wired as you state above you have RX going to RX and TX going to TX. RX should go to TX and TX should go to RX.

      PaulS replied to the thread GPS not working with Teensy 4.1.
      Strangely enough, I couldn't get DeviceExample.ino to work with SoftwareSerial also. So I tried using hardware serial on pins 0 & 1 instead. That works! Mind you: I had to connect Teensy TX1 to module pin RX [green wire] and Teensy RX1 to module...

      Where in your code do you actually read out the data from the GPS module? From this page: Perhaps it's a good idea to get the DeviceExample.ino [using SoftwareSerial and your pins] operational first and then move to HardwareSerial. Paul

      PaulS replied to the thread dac8568 teensy 4.1.
      For a really basic test of the DAC, I would get rid of the MIDI code and just send a digital value to each of the DAC outputs and measure the voltage on that particular pin. Did you try your code above? Did it work? Paul
    • PaulS
      Tried the above code on a different ESP32 module and it works. This DOIT ESP32 DEVKIT V1 module also shares the first serial port [TX0 & RX0] with the onboard serial-to-usb converter and thus is not usable for external comms. So had to use TX2 &...

      If I understand this section of the FireBeetle board WIKI correctly, pins 1 & 3 are used for the serial communication to the PC/Arduino IDE. For a comm link to the Teensy, you need to use UART2 (Serial2) on pins 16 & 17. Your code would look like...

      PaulS replied to the thread Teensy 4.0 / High Voltage Heater.
      Hi Jordan, no, unfortunately that doesn't work that way. Thing is you can only send bytes (values if you like) over the LIN bus. Electrically they are just 0's and 1's. What these bits mean, is up to us. We start with a lin.order() command and...

      Actually not... Serial0.begin also works for the ESP32-C3 UART #1. void setup() { Serial.begin(115200); Serial0.begin(9600); Serial0.setTimeout(100); } void loop() { while (Serial0.available() > 0) { Serial.print("Message received...

      Well, gave it a try myself. Took me some time to find out that I had to use the HardwareSerial class to receive data by my ESP32-C3 SuperMini board... Anyway, it's working now: Teensy 4.0 code: void setup() { Serial1.begin(9600); } void...

      While @AndyA's remark is certainly valid, I would focus on the serial port connection first like @jmarsh indicated. Your Teensy code should look like this: void setup() { Serial1.begin(9600); } void loop() { Serial1.println("Hello Boss")...

      PaulS replied to the thread Teensy usb midi problem.
      So you have been using (and are using) an external USB hub all the time? Is it possible to test without this hub? Also, the timing remark by @MatrixRat does make sense to me. Paul
    • PaulS
      Found this schematic with resistor values [but not LED Vforward]: If that resistor value of 330Ω is true, a Teensy pin outputting 3.3V will probably not get the optocoupler LED to conduct sufficiently. Paul

      On the pinout card, the yellow-background signals are all related to digital audio I/O. They can also be used for other purposes if you don't use these particular signals. Paul

      PaulS replied to the thread Loop Back Error -.
      Teensyduino comes with its own PulsePosition library. You should delete the one here C:\Users\Primary\Documents\Arduino\libraries\PulsePosition. Then your code compiles fine (just tried). Paul

      Teensy does not use a hardware serial port for uploading. Instead it uses a "virtual' serial port over USB [under the hood, it is a bit more complex than that but for basic understanding OK to work with]. That same virtual serial port is also...

      Looking into the Teensy RadioHead library, in the examples/Teensy folder, I noticed the README.md states: In your code, you use #define RFM69_INT digitalPinToInterrupt(3). Perhaps you should connect the G0 (IRQ) signal to Teensy pin 0 or 1...

      Great result! Happy to be of help in reverse engineering in what was nearly a black box [but not any longer now]. Well, I hope you get the other heaters to communicate as well! I will check the wiki page every once in a while. Paul

      PaulS replied to the thread Teensy 4.0 / High Voltage Heater.
      Both commenting _stream->read(); and modifying data[i-3] = tmp[i-1]; serve the same purpose: correcting the wrongly shifted byte. So you should choose either one. When I run your code, I get this response: Same response but correctly shifted by...
