    I guess I should have waited 2 more days. I was quietly watching this as wanted SD and USB for my Teensy 4.0's so I ordered a set of the PCBs last 2 nights ago in the .8mm thickness so I suspect in...

    Hello,

    I'm using Serial 1 & 2 vs 6 and also upped the buffer in the serial code from their default 64 but adding debug code I have not seen my serial buffer getting used beyond 64char (usually...

    Hello,

    The module I am using is http://www.canadarobotix.com/bluetooth/rn42-xv-bluetooth-module-pcb-antenna and the datasheet they reference is...

    @Frank - yes, I tried it and it seems to work. Still trying to figure out why the BT adapter is causing the issues in the first place for my own curiosity but at least now it powers up consistently...

    Working from home sometimes has its benefits. Boring con-call so I did more review of my teensy 3.6 power issue. I didn't follow standard debug procedure .... I removed the sensors from my board...

    I am starting to think at some point I may have damaged something hardware wise with the startup of my Teensy 3.6. Even feeding 5V into Vin of the board seems to be hit and miss, the voltage reg...

    Paul,

    The item I had a problem with is Digikey PN 945-1661-5-ND (http://www.digikey.com/products/en?keywords=945-1661-5-ND) which is the 500mA version and is the version that seemed to have solved...

    Thanks for the reply. I am using the 500mA version and from datasheets the items connected to the 3.3V (other than teensy) is currently about 75-80mA. I probably have a few other sensors < 10mA...

    Hello,

    I was about to start a new thread but then found this when searching 'Recom'. I want to use a Teensy 3.6 on a motorcycle for a data logger and thought I would use a Recom R-783.3-0.5 to...

    That matches what I found in my research as well, you want to stay to Classic modules and not LE modules if you want throughput. I moved to a RN-42 module at the moment communicating with Teensy @...

    Hi Bill,

    I was wondering if you are planning to share your latest work with ChibiOS/RT on Teensy 3.6?

    I used your https://github.com/greiman/ChibiOS-Arduino on an Arduino in the past but...

    Hello,

    I have a similar problem where I would like faster comms with a bluetooth module. I was wondering if Adarsha or CraigF has any luck with other modules. I have the cheap ZS-040 at the...

    Thanks. I did download the datasheet and did some reading there first but wasn't looking for the right thing and still learning on how to find what I need in large complex datasheets. Still kinda...

    Hello,

    Yes, I saw the i2c_t3 library and that is what spawned this thread as it didn't seem to confirm the ports are truly independent, I think I actually saw something in the i2c_t3 thread that...
  17. Teensy 3.6 - multiple I2C ports still 1 bus and therefore all same speed?

    Hello,

    I have a selection of sensors I would like to connect with I2C. Most will support 400Khz I2C but 2 are SMBus 100Khz. Reading the datasheet for the K66 it seems the multiple I2C...
