I think you have Teensy2.0 selected in your boards? You should also update teensyduino i do believe they are for the T3.x series

You'll be happier with the T3.x series. If you go with the 3.5/3.6 you'll have 3 dedicated hardware SPI busses and faster performance :) Also you have 3 I2C busses on 3.5 and 4 on T3.6, T3.2 only has 2. If you put on...

moveTo uses absolute positioning of the pixel size on your screen. So if you got a coordinate based on screensize, thats exactly where the pointer will go if you change screen resolution, obviously you'll need to write...

Thanks but my libraries were tailored for teensies and won’t compile on most if any arduinos due to their old toolchain and lack of C++ enhancements, and being teensy specific, so going through the hastle of their...

Thanks Robin. :) However, the title may be misleading a bit as it's an SPI interface library (not I2C per say), which is however capable of remotely accessing the I2C/Serial/SPI peripherals attached to the slave....

the uart register of the first field is different per UART port, however, the second field is common among all UART registers. UART_S1_FE is valid for all status registers of UARTs, theyre all shifted the same way...

Circular_Buffer library not added yet since request on teensyduino 1.42 beta3 thread... DId I miss some registration process? :)

you could always control other teensies many of ways, via UART,I2C, SPI,CAN, ETHERNET, etc

dielectric grease is good for pogo pin setups :)

why not use a DC-DC converter that takes 8-40V input and gives a regulated 3.3/5V output? Do you need a "battery" type of system in the vehicle? If so, along with this, you could goto any local alarm supply store and...

I created 2 libraries similar to do this which controls multiple node peripheral ports over the SPI or CAN network. However, the CAN version I managed to make it multi-master and concurrent access, so everything both...

spi/i2c isnt designed for long distances, obviously lowering the clock helps, but that is just a bandaid, you’ll also need to handle the reflections using a very small resistance... if this is your “EMI” issue for...

definately a code issue, of which we cannot see. An example would definately help us point you in the right direction

sometimes if the gas pedal is to be expected to drive a car, doesn’t mean the ignition is running. Loss of expectations :)

im just surprised you managed to get a com16 with a power cable :)

New update: IMCTFD now supports Teensy LC ! Note, TeensyLC does not support TeensyThreads, so when using TeensyLC, the library will transparently switch to use IntervalTimer instead

try to goto device manager port settings of com16 and force it to use a different port number

you tried holding the program button before plugging teensy in the PC?

did you disable your antivirus before installing teensyduino? also teensyduino must be instealled AFTER the IDE is installed 1.8.7 and 1.44 work fine here

I’ll also mention on the LC, SPI1 in slave mode is faster than SPI0, so it will be better to use SPI1 as slave and SPI0 for the strip if you plan to use the LC.

if no one can help you figure it out in a reasonable time get a fleabay equivalent strip link as yours and ill order one to see what i can do :)

if no SS, just use SS from master to slave only then for the MCU link

you should run the SS line into an attachinterrupt on the slave, and not use SPI transactions on the slave when it connects to the strip. Whether this works or not (based on above) is beyond me, but worth a try. Also...

pocket sized N64 with Super Smash Bros! :)

Good evening everyone. I worked on getting a simple example posted on the repo, and..... the library has been posted! Hope you all like it :) Thanks to Mike for finding bugs and running tests in his spare time :) ...

for sure ill be working on one whenever the 4.0 comes out :)

flexcan has it’s own memory mapped address used only for itself, not sure if you can use it without CAN..

Hi all, just a few more tests need to be done. On points 14, 15, and 16 of the readme on github, i added (like IFCT) filter enhancements and message distributions. I've also implemented (like IFCT) a background task...

if you’re worried about SPI over long distance, I wrote a protocol for teensy 3.x to control multiple node ports over CANbus, of course, the limitation is the bandwidth of the bus (1Mbps max), by hosting another teensy...

for what you want, differential RS485 or CANBUS is needed.

you could replace all references to Wire with Wire1 in the library and that should be it, but you didnt post code or library so were just speculating here, limitations are on the libraries you use

would have been nice to have FD support, currently working on T3.x library for the 2517FD similar to ifct

if your getting that serial error its most likely your code the issue, if your program crashes and hard faults the cpu you’ll get the same error youre getting

if your worried about corrosion you could always brush on a thin layer of die electric grease :D

multi- master 2 way control with parallel communication actually, good for centralized sketch code :)

Last year the forums had interest in CAN, this year looks pretty dead with an exception of a small handful of people who actually do show interest. with CANFD your not limited to the 8 byte payloads of CAN2.0 but in...

CAN2.0 is more mainstream in the automotive industry than CANFD, if you were to favour CANFD over CAN pinouts some people might get depressed or not :D Irregardless, with CANFD being 12MBits and a proper library it...

is SPI_MST long forgotten already? :) LC,3.2,3.5,3.6 supported (teensy to teensy only)

never funny, but possibly true :) Hey Tim, thats the release you got! lol

pinMode(pin,INPUT_DISABLE);

is he declares +1, he will still run into the == issue, he should be doing if (num == MAXCHANS -1)

programming is done over HID, NOT serial. If you have serial driver issues, it's not HID related..

well all the usb ports on the pc have a common ground, you are not using AGND are you? use GND points only

are you using common ground?

I might order a few too, looks like it could need a sister library like IFCT :) It all depends on my free time of course Tony

your other teensies were already programmed, by default the actual USB is not enabled on new teensies until you flash it with it enabled if you had an issue with a windows driver, its possible your usb driver was not...

sorry but you absolutely need to run begin(), why you comment it out?

After testing out the MCP23017 attached to the T3.6 while the T3.5 was accessing it, I decided to attach a MCP23S17 (SPI) variant to the Teensy 3.2 node on the network. Here's the loop code on the T3.5 to talk to the...

New update! Aside from including Wire capabilities, I2C_T3 support has been added to CANquitto as well. An example of which is: node123.Wire.begin(I2C_MASTER, 0x00, I2C_PINS_18_19, I2C_PULLUP_EXT, 100000); SPI...

make sure they have common grounds, testing from a PC though, the USB cable is already grounded to the PC so that will work for sure, but you need a ground from teensy to your device if you want them to talk

the contact has a miniscule resistance which wont beep, you should be able to see the value though if your reading the ohms, like taking a resistor and trying to check if the voltmeter beeps :)

that spammer who posted here i messaged him on facebook to stop flooding the forums and reported him, he “viewed” my message within a minute and never responded. He’s definately doing it on purpose

you need IFCT, Circular_Buffer, and CANquitto libraries installed in arduino user folders, You can’t write to Node, it is a singleton class just for the master node config. You need to construct a node to talk to...

Today's update for CANquitto: Wire (I2C) has now been integrated into the protocol. It's based off Wire.h from Teensyduino. This week I plan to add i2c_t3 methods as well, the library will give you a choice to run...

Hi Paul, I'm poking around the Wire libraries for Teensy 3.x for user option choice for I2C over CANquitto, and noticed that i2c_t3.h has Wire3 declared but Wire.h throws a compile error, only Wire,Wire1,Wire2 are...

reed relays are silent, to an extent, you'd have to be very close to it to actually hear it, like silent room with ear near it... when power is applied, a magnetic charge shifts a tube inside to make contact.

You probably only need a 74HCT4066(TTL) for that type of thing. Use a gpio to trigger a pin and the bilateral switch will join the contacts of the camera
