Re: 5" touchscreen issues
John: There's a function in the EEPROM.cpp file called ShowEEPROMValues(). Try calling that function near the bottom of setup() and see if the EEPROM values make sense. Jack, W8TEE

My working hypothesis is that the touchscreen is recognizing touches since I can see them in the debug trace and that the root problem is that calibrations are not being stored. Next avenue of investigation is the EEPROM functions and related libraries. Certainly open to any suggestions the group has as it feels like a s/w issue at this point - i.e. something changed since this configuration is working for some.... 73, Joe AF4XS |

Re: 5" touchscreen issues
Our web site was hacked and each time we fixed it, it got hacked again, so we haven't tried for some time. We have not done anything new with the JackAl, but will continue to monitor this group as best we can. Al and I have be swamped with the new Projects book, which we hope will be out in July. Al and I have both ordered T4.1's but they are not here yet. Also, with editing page proofs, I'm not sure when we will get back to the JackAl. Keep us posted, as the JackAl should fly with the new T4 series! Jack, W8TEE

hey jack I have been working on your code to port it to teensy4.1 we have 1 library that has to be fixed I fixed one already. the OpenAudio_ArduinoLibrary does not have the speeds and mcu support for the teensy4 /4.1 yet I have been working to fix it. and we have redone the pins for a new layout. Are you still developing or have you dropped the project as lat updates are like a year old and the website seems to not function. ?

Re: 5" touchscreen issues
Which Teensy are you using? Jack, W8TEE

as far as I know this project died no code updates . I have been looking ta the code and compairing the 2 vresions the touchscreen code did not change. Execpt a few new functions ------ Original Message ------

Re: 5" touchscreen issues
I was just giving some back story.? I have many projects going on besides the Jackal. :)? I have not even tried the 4.1 with a RA8875 yet, I just got one the other day.
Was just letting the OP know I ran into some problems with the RA8875 using different Teensy boars once I upgraded to the latest Teensyduino 1.52. 73 Michael -- KE4EST |

Re: 5" touchscreen issues
I use several Teensy boards for a lot of things.? Been playing with the new 4.1 as of late.? I use a few of the RA8875 screens.? As soon as I installed Teensyduino 1.52 final I ran into all sorts of issues with the 8875 screens.? I went back to 1.52 beta #5 and they started working again.? There is a couple of threads on PJRC forum about others with the same issue.? I am sure Paul will have it fixed soon.

I suspect the calibration values aren't being stored for some reason. Any ideas from the group? 73, Joe AF4XS |

Re: Greetings! Starting my JackAl build

Little more progress....
BTW the JackAl board was complete when I purchased this from another ham. And I found a through hole 10ohm so that is on the protection board for the moment. |

I've started building SMT kits recently, and had a bad moment when an 0603 resistor squirted out of my tweezers. I spent about 20 minutes carefully searching my workbench for the wayward chip. I eventually found it, and immediately soldered it down. Then I got on Ebay and bought a big sample book of 0603 SMT resistors and another of capacitors, and some empty sample book pages for the various SMT parts of different sizes I have in some SMT solder practice kits I had lying about. They were smaller than the 0603 I was temporarily missing, and I have some 0804 sample books, but 0603 was a size I didn't have yet. I've been buying SMT components when I get a new kit. I roached an Si5351A trying to clear a solder bridge, so I got on Mouser's site and ordered a small tube of 25 for my stock, along with some regulators in different voltages and other common parts, like LM386 amps. If you don't know about the wonderful things called sample books, they're small loose-leaf books with divided pages that contain small sections of reel-tape, with components of various values. The resistor book I ordered has 50 each of some large number of values in it, for a total of 8500 components. I paid a?bit more for?1% tolerance. The capacitor book is a bit smaller, 50 each of 90 values, either NP0 or X7R tolerance. They cost a bit, but they'll last me for years! (I know, there's a chance they'll cheat and send me 5% resistors, or lower-tolerance caps, but their feedback looked ok, so I have my fingers crossed.) I could have saved some by ordering from Banggood, but I want the sample books BEFORE the next ice age! I hope the project turns out great!? -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Thu, May 14, 2020 at 10:12 PM jason kitchens <jasonmkitchens@...> wrote: I'm starting my JackAl build with a V4 uBitx and 5" display and it been an interesting ride so far. |

Greetings! Starting my JackAl build
#jackal
I'm starting my JackAl build with a V4 uBitx and 5" display and it been an interesting ride so far.
Anyone else working on their build? Here's a pic of the almost completed display protection board. I need to find the missing 10 ohm 0805 to finish the board. |
