Initial Test of Main V12.6 board
|
I'm following the Main Board build instructions. The first tests went well, i.e. 3.3 and 5v tests.
On the next test, i.e. loading the i2cscan.ino, the serial monitor reported No I2C devices found. However, in another popup window, it said Press Button on Teensy to manually enter Program Mode, with i2scan.ino.hex 1% used on the status line.
With the audio hat on top of the Teensy 4.1, I cannot access the "button". Should I remove the Teensy from the Main board, remove the Audio Hat, and then program the Teensy by itself first? Best regards,

开云体育Yes, you can temporarily remove the hat.? Program the Teensy, turn the power off… and replace the hat if you want. ? ? Dr. William J.

开云体育It should be finding the hat at WIRE at 0x0A… ? Its either not recognizing WIRE or its shorted somewhere. ? You can remove the teensy and hat off (as one unit)… jump the voltage tab that you cut in the instructions (UNTIL YOU REINSTALL THE TEENSY BACK ON THE MAIN BOARD), plug in the USB cable as if you were programming the Teensy, but rather to supply power and see if 0x0A shows up.? If not you have it located in a connection between the hat and the Teensy. ? You can also just build a small section of one of the other boards that includes the I2C stuff… cable it to the MAIN board and see if it sees it.? The logical choice is the Front Panel… and you just need to install the IC’s, connectors, and the jumpers on the electronics board of it…not the switches to see if it at least can read that board. ? ?

Still no I2C device found :(
I ohmed out all the connections between the stacked header pins through the Teensy and to the Teensy Audio adapter. I found some intermittent connection issues, which I think is due to the Tayda A-4662 male pin set for the Audio Hat. I noticed that Tayda sent me a substitute part, and I noticed that the pins were not as long a normal pins. So, I started over with a new Teensy 4.1, offset Audio adapter board and Teensy Audio board and longer header pins. I took lots of time to ensure that all solder joints were good and then used an ohm meter to check each pin from the stacked header pins to the Audio board. All were good. I programmed the board with just the Teensy, adapter, and Audio board. Arudino IDE notice a? new board and port and did some automatic updates.?
The is started reporting no I2C device found. I'm not sure where to go from here...2 strikes. I am using Arduino IDE version 2.3.6 Maybe I am missing a library?? ?

开云体育John… ??Two options. ? If you programmed the teensy separated from the MAIN board and ran the teensy + hat off the just the USB cable powering the teensy thru the computer… and it doesn’t see the hat… either the hat is bad, or the hat is not making connection with the pins on the teensy, or the teensy is bad.?? That’s all there is. ? If the teensy is now on the MAIN board, build the front panel board and cable it up to the main board.? see if it sees that. ? ? Dr. William J.

Thanks Bill, I appreciate your help.
I've had a lot of years and experience building electronic gadgets but has really perplexed me. I've been through 2 sets of Teensys, adapter boards, and audio hats, with the same results. They say the definition of crazy is to keep doing the same thing and expecting a different outcome, so though I have 2 more sets of teensys, boards, and audio hats. I don't want to a keep doing the same thing.
My next attempt? will be to test the teensy separately on a different I2C breadboard circuit. Then if that is successful, I will dig into the audio hat documentation and see if I can breadboard a working circuit with it.?
Of course, I will try the one suggestion from you that I haven't tried yet, i.e. building and connecting the front panel board.?
Best regards,

John: I would simply plug in the USB connector on the new Teensy, before you even solder pins on it, and run the ASCII Table example program. I use this program (Example-->Communications-->ASCIITable) because it also writes to the Serial object as part of its execution. If that's okay, at least you know you have a working Teensy and IDE. I would then hook up the Main board and the display and see if that works. If not, you should still be able to run the "Gauges" program that's in the RA8875 library (no hat necessary). If that fails, then something is wrong with the display or the Main board. Also, these simple tests don't use the front panel at all, so you don't have to contend with those, either. Jack, W8TEE

开云体育Yeah you’ve got to build that front panel board anyway at some point… so give it a try and see if the test program can find that I2C device.? Remember that the teensy has THREE I2C busses and we use all three… meaning that two could be working just fine while the third has a short of some type.? ? The test program looks at all three busses for specific addresses. ? ? Dr. William J. Schmidt - K9HZ J62K(J68HZ) 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ?

Thanks Jack and Bill,
Yesterday, I successfully ran the ASCII code.
Today, I built the Front Panel board and connected it. Success on Wire1. I2C device found at address 0x20: Front panel MCP23017 for switches 1-16 !So, it's between the Audio Adapter and the Teensy Audio Hat. I have ordered some Stacking Header strips with enough pins that I don't need to Dremel two 12 pins to make them fit. That is my only guess, that the two sets didn't line up perfect and maybe one was pushing on the connection one way and the other the opposite way. Until they arrive, I will look into the PRCJ docs on breadboarding the Teensy with the Audio Hat to see if something turns up.
Am I the only one that this happened to, not only that but two board sets in a row.
Best regards, John K1JO |
开云体育Ok one more test you can run… The AUDIO HAT… and the RF board uses “WIRE” (not “WIRE1” or “WIRE2”)… so you could build the control portion of the RF board and try that to make sure that “WIRE” is working correctly.? I guess you could also connect to the “RF CONTROL” connector on the MAIN board to a bread-boarded MCP27018 with address 0x27 (which is “111” for A0, A1, A2) to see if it returns the part imitating the RF board.?? You just need pins 1 = SCL, 3 = SDA , and 5 = GND. ? ? Dr. William J. Schmidt - K9HZ J62K(J68HZ) 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ?
