Hi there, I wrote a small post about how I modified the Reload2 active load to add programmability using the Teensy3.1 DAC and reduce the amplifier offset voltage, leading to a lower load current: http://www.embeddedrelated.com/showarticle/775.php I hope you will find it interesting, if not...

Hi Paul, I am also interested to know why the EZP_CS is not connected. As I understand it, the MINI54TAN uses the EZPORT to program the MCU flash. How can it work if EZP_CS is left floating ? Could you post the reply you sent by email here ? Thanks !

Hi, I am porting the code of a previous project from teensy3.0 to 3.1. I am using the latest version of the teensyduino (1.18). I also use the command line version of the loader application, which I had to modify to support mk20dx256. I made it available here, if anyone interested...

I ordered 7 teensys3.1 2 weeks ago and received today. Very satisfied.

Hi, I am designing a TEENSY3.x carrier board for a project which measures 2 voltages. I saw that the TEENSY3.1 has 2 independent ADCs, and I will use them both so that measured voltages are sort of synchronized. I also want the carrier board to support TEENSY3.0, using ADC0 channels...

OK, I understand now ... thanks for your reply. Actually, using AD7A would not work.

Hi, I downloaded the latest version of the teensyduino program and looked at the analog.c implementation. I see you are using the alternate channel set by setting the MUXSEL bit: ADC0_CFG2 = ADC_CFG2_MUXSEL + ADC_CFG2_ADLSTS(2); Can anyone explain me what is the reason for doing so? In my...

Hi, I wrote a small article on how I interface a RASPBERRY PI / LINUX with the TEENSY3.0 in recent projects. It only gives details about the LINUX side, but I thought it might be of interest to some of you: http://www.embeddedrelated.com/showarticle/173.php Fabien.

Hi, I tested your code and it works well, thanks. I added a function so that control goes back to the MINI54 if TEENSY MCU is currently running. The modification is here (switch_to_mini): https://github.com/texane/teensy3/blob/master/src/loader/load_linux_only.c It might not be necessary in my...

Thanks very much for your answer Paul.

Hi, Sorry if it is a naive question, but I am trying to figure out the purpose of the MINI54TAN mcu. I thought the MK20DX flash memory contains the bootloader AND the program uploaded by the user ... so why is the MINI54TAN mcu needed at all? Thank very much for helping, T.

Hi, Thank you very much, I will have a look at it during the next week but it looks very like what I need. I understand testing a software through different platforms is time involving and that it is not part of your priorities for now, so I wont ask questions unless really necessary. The...

Hi, Thanks for this tiny but great board. I need to program the TEENSY3.0 from another platform the GUI loader does not work on. To do so, I would need the documentation of the loader protocol the TEENSY3.0 comes pre programmed with. I read through the forum, but it is very unclear to me what...
