    Teensy 4.1 replacement Capacitor?

    Oups missed that doc thanks! and is the package 0603? Would this be a critical component that if broken would explain that the teensy is dead? or is it a non critical decoupling cap?

    Teensy 4.1 replacement Capacitor?

    Hi, I have a teensy 4.1 that was dead on arrival, I noticed a capacitor seems broken so will try to replace it. But I need to figure out the value, its the one closest to the usb plug on the bottom, see pictures below Any hint to the part number or capacitance value and package of this one? Thanks!

    Teensy 4.1 ethernet header position mesurements for custom footprint

    Yes That's exactly how I do it. I've done it in the past and didn't have a problem with solder going into the sockets, I don't think it would be a problem as long as you don't put an excessive amount of solder. I guess the surface tension in the hole keeps the solder there, I wouldn't worry too...

    Teensy 4.1 ethernet header position mesurements for custom footprint

    Oups I did a quick search but didn't get the keyworks right, thanks for the link. Concerning the connections below, I'll be using these low headers and pins for the 0.1in connections, since the ethernet headers are lower than the average 0.1in headers...

    Teensy 4.1 ethernet header position mesurements for custom footprint

    Hi I'm trying to make a custom footprint for teensy 4.1 to get the ethernet pins to go straight down into the pcb through a header without using a ribbon cable. Could it be possible to get the exact measurements like in the picture below from the center of pin 20 to the center of ethernet pin R+...

    Encoding multiple lower sampling rate audio signals in 44100 (over usb audio)

    I'd like to send more audio signals over usb then 2 (I need 18 actually) and they can be lower sampling rate, so I've though of a way to packet (encode, decode) audio samples sequentially into one audio stream. Let's say I have a 44100 signal, and I want to decode 3 signals at 14700 sampling...

    SSD1332 and SSD1331 fast drivers

    Hi, I'm using sumotoy's SSD_13XX library with a ssd1332, and text is mirrored, I can't seem to find an option in the code to mirror the screen, have I missed something? Any hints?

    DAC pin for analogWrite? (led strip PWM, running out of pins)

    Hi, I'm running out of pins on my current design and was wondering if it's possible to use pin 26 on a teensy LC (the DAC pin) to dim an led strip through a n-chanel mosfet? (IRLB8721) Can I do analogWrite(26, value)?

    I2S audio chain with multiple teensy

    Hi! I was wondering if it's possible to chain multiple teensy together with quad I2S audio? like having 4 or 5 teensy or feeding into the next Teensy1>Teensy2>Teensy3>Teensy4>analog output

    SSD1332 and SSD1331 fast drivers

    Yes that's the idea, same spi but different chip selects, don't know yet if it with be a teensy or sam d21.

    SSD1332 and SSD1331 fast drivers

    Thank you! I'll have a projet with many 1331 driven from a single microprocessor soon, will try this out

    SSD1332 and SSD1331 fast drivers

    Thanks, that sounds great! Do you think it was the old ssd1331 library that was causing problems sharing an spi bus using the new spi library?

    Spi for both wiz820io and OLED ssd1332 not working correctly

    So indeed it seems this oled is actually a ssd1331, there are exemples in this thread of people getting the 1332 library working with a 1331 oled but not getting the 1331 library to work. https://forum.pjrc.com/threads/25719-SSD1332-and-SSD1331-fast-drivers/page2?highlight=ssd1332

    SSD1332 and SSD1331 fast drivers

    Hi Sumotoy, I'm trying to use your library with a ssd1331 and a wiz820io and the shared spi bus is not playing nice and causing the teensy to misinterpret the wiznet's incoming upd and freeze everything. Here is the thread about this problem...

    Spi for both wiz820io and OLED ssd1332 not working correctly

    Just tried teensyduino 1.28 with arduino 1.6.8 and still the same problem. I was using the ethernet library straight from your github Paul, now I'm just using the one in the teensyduino package. Here is the library I'm using https://github.com/sumotoy/OLED_SSD1332 it also needs a modified...

    Spi for both wiz820io and OLED ssd1332 not working correctly

    So am I getting this issue from the arduino's ethernet library inefficiency? As I understand it the polling and interrupt shouldn't be a problem in my case? Any other suggestions? Thanks

    Spi for both wiz820io and OLED ssd1332 not working correctly

    Hi, Actually nope, it's not using the interrupt, and I'm using beginTransaction/endTransaction in the code to guard against this kind of potential problem.

    Spi for both wiz820io and OLED ssd1332 not working correctly

    Hi, I've tested the wiz820io and an ssd1332 OLED with a teensy 3.2, each separately and they both work. Now I'm trying to use both at once with different chip select pins. To test it I have a counter that is displayed on the oled and the upd send receive string example with processing. At...

    Multiple teensy on i2c, multiple pull-ups?

    Great info thanks, I should also say that the i2c will be traveling the 8 feet mostly on pcb traces with just an inch of wire between each pcb, don't know if that makes a difference? I'm trying to figure out the PCA9600 to use it in the simplest fashion. I would need to connect SX and SY to...

    Multiple teensy on i2c, multiple pull-ups?

    Hi, I'm planning on connecting 10 teensy on an i2c bus over a distance of 8 feet. Should I have pull-up resistors on every teensy or just on the master teensy at the beginning of the chain? Thanks!

    Teensy LC pcb thickness

    Hi, I'd like to know what's the thickness of the teensy lc's pcb? 1.6mm? or less? What about the teensy 3.2? Thanks!
