Looking at your code I noticed this line: servo1.attach(14, 500, 2400); Is there a reason why you deviate from the standard values of 1ms and 2 ms, like so? servo1.attach(14, 1000, 2000); Paul

More commonly known as XY-016 module. But still very limited in specs. Paul

Yes, I do mean the control signal pin. The specs of the Tower Pro MG90S do not mention a minimum voltage for the control signal amplitude. I also did not find any specifications of the WHS15024 boost/step-up converter. Do you happen to have specs...

Now I'm not familiar with the Tower Pro MG90s, but when you power them with 6Vdc, is the 3V3 output of the Teensy sufficient amplitude to reliably drive the PWM control signal? Paul

If I'm correct, the Serial Port Profile is not part of the BLE spec. See this answer. Found this too. Paul

Mouser even has 15K+ pieces on stock. I would buy Teensy 3.2 if they are available - I have actually never needed the processing power of the T4 [and the related power consumption]. Paul

Agree. Like his other post. Paul

@AndyA. The prev message (WillimamsimC) seems ChatGPT generated an should, MHO, be considered Spam

It's related to the SdFat library. Syscall::yield and SysCall::halt were apparently removed in V2.1.1 of the library. Paul

Thanks a lot! Wish I would have known this feature long time ago... Paul

A 1920x1200 PNG file can be uploaded without problem. So perhaps shrink your photo? Paul

Reviewing the board files and the schematic, I think the power supply to the Teensy is fundamentally not correct. In the schematic, the Vin pin is labeled "+3.3V". That 3V3 comes from a regulator mounted on JP13. 3V3 is too low to power the...

In Eagle, you can [1] "Print to File (PDF)" which looks very readable, or [2] File > Export > Image. Choose resolution '300dpi' and it will output a very readable PNG image. Your design seems to be done in Eagle 9.7 which I can not open in...

OK, took me a while to figure out you meant BOB-10124... This board. It is indeed not really clear from the schematic and silkscreen on the PCB but the RTS signal should be connected to pin 4 of J9: The LED will be ON when transmitting and OFF...

Had a look at your code but nothing obviously wrong stood out. What if you integrate only 2 sensors at a time [BME680 & MQ135 or BME680 & GPS or MQ135 & GPS]? Any combination that works? I guess it is a matter of commenting out parts of your...

Welcome to the forum. You may want to share more and higher resolution pictures. I tried to see where the wires go from the display to the Teensy, but it's not discernible. Please share a schematic and your simplest code that shows the issue...

I think it changed here. I assume it was for a good reason then - hope it's not going to bite us somewhere else now. Anyway, thanks very much to @PaulStoffregen and @jmarsh after indepth sleuthing! Paul

Could it be a timing issue with the one-wire interface? Teensy 4.x is pretty fast so perhaps some timing could get on the edge. Heating and/or cooling the IMXRT1062 chip carefully might reveal something. Paul

I had a quick look, I think I know what the cause is but I'm not sure of a few details. If you look at the memory allocated immediately before the ClocklessController there should a 4-byte guard variable. Guards are generally used for local...

Yes, sounds good to me. I'm running it now and FastLED seems to be working. Committed the fix just now! https://github.com/PaulStoffregen/cores/commit/638a2079d290e3d6683aeceb07b6dfd8b09151a9

Did you measure that 2.5V on the Teensy VIN pin? Is the Teensy powered over USB? Paul

I suppose you are trying to read out these registers? Not sure whether I can be of any help here. I think you just have to fiddle with the settings until you read something that looks valid. Paul

This is a bare PT100 “Resistance Temperature Detector”. It's basically a resistor so it does not output a current. You can not hook up such a resistor to a 4-20mA current loop. Whatever circuit you will be using to measure the resistance [and...

Do you have a datasheet or part# for that transmitter? Paul

It may well be a worn-out or low quality breadboard. Breadboards vary a lot in quality. A lot of chinese breadboards are very cheap but low quality - you get what you pay for! Two brands stand out: 1. BPS [BusBoard Prototype Systems]. I have...

Did you check the sub-settings as well? See the manual, paragraph 5.7.4 Analog Output (AO) and 5.7.4.1 AO Detail Settings. OK, but what voltage did you actually measure then? You said "it doesn't match the intended 2V" so I'm curious what...

OK, so that's not going to work. Back to the previous code. Are you actually using this product: IO5202 with 4 AI/AO? Another question on your message #24. You stated: What did you actually measure? Paul

Lin.read is a "private" function in the library, as defined in lin-bus.h: private: Stream* _stream; void send_break(); void breaklength(uint8_t length); void breaklength_35(uint8_t length); void breaklength_LP(uint8_t length); void...

OK, at least we can rule out that checksum question for now. Perhaps, but I don't know enough about those LIN timings whether it's mandatory timings or minimum timings. It certainly looks like ID 34 is the "Write power" command register...

OK. I modified my LIN-slave to respond with a classic checksum on 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, being CRC 0x99 [153 decimal]. Now when I modify this line of your code CRC = lin.response(responseID, linRXdata, 8, lin2x); to CRC...

Hi Jordan, it seems ID 23 is the register to focus on first. Yes, that's weird. In order to verify whether your code may have an issue, I used my homebrew LIN-slave setup. I fabricated that setup a few weeks ago to verify the claim that there is...

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 =...

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

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...

When using Arduino IDE 1.8.19, you can download Teensyduino 1.58.2 here: https://www.pjrc.com/teensy/td_158/TeensyduinoInstall.exe. Paul

Using Arduino IDE 2.3.2, I'm using the Boards Manager to switch between Teensyduino versions: Paul PS: I ran into an issue when when updating from 1.58.2 to 1.59: Need to look into that now... Update on the precompile_helper": file does not...

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

Ran the exact code from message #6. Runs on Teensy 4.0, does not run on Teensy 3.2. Related is this thread. Paul

Posted an article on the website today with info about how the Windows EXE cross compile and signing works. https://www.pjrc.com/how-to-cross-compile-and-sign-windows-exe-on-linux-with-yubikey-token/ Hopefully it can help other people who want...

Here you go. On Windows 10. My Chrome browser downloaded it fine, hello2.exe runs fine from command line. 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() {...

Yes, your design will do. Set the sine module output to 1.0 and set the attenuation or amplification at the amp module. Paul

It looks like you are restarting an old thread. You better continue the old thread. Did you follow all the advice given by @defragster, @mjs513 and @BriComp? Paul

Or short press-fit header pins? Link. Paul

In combination with these kind of pins for the Teensy? Link. Paul

Are these an option? 2.11 mm clearance. Specification here. Paul
