No light on the keyboard usually means no power on the USB Host port which means the myusb.begin(); has not been executed or there is a wiring issue on the USB Host port I just ran your code in the IDE and plugged in a MIDI keyboard and it...

@mjs513 I'm impressed! With the Uno Q hitting everyone's doorstep I figured this would be lost in the shuffle for quite awhile, so thanks for pushing a release out. i will definitely be checking it out and I think it will prove to be a pretty...

My last order came in pink poly as well. Besides inadequate ESD protection, the oversized thin poly bags also don't protect as well from physical damage. The fact that the bags are preprinted makes me think it may be a permanent change...

Checking in to see if there is a plan to eventually roll this new slider functionality into the TeensyUserInterface library?

This link might give you some ideas: https://github.com/Rob65/TeensyScope

The current 8MB PSRAM with 2 installed can work OK with the QSPI bus cranked up to 166.2MHz. There are 16MB PSRAM chips becoming available soon for a total of 32MB/256Mb, but they are limited to about 120MHz with 2 on the QSPI bus for a...

Pink poly does not provide adequate protection. There was a note on the SparkFun website a few days ago about shipping in different packaging, but that note seems to be gone now. Hopefully it was just a temporary packaging issue and they are...

You have signals on both sides of the level shifters labeled the same. That will cause EasyEDA to connect them together on the PCB. Use different names like BUS0 and BUS0_5V to separate the 3V bus from the 5V bus.

The buffer will work OK as long as the Vcc pin is connected to 3.3V. That is unclear from the schematic. It will then accept 5V or 3.3V input and convert to 3.3V to the Teensy. The 0.1uF cap placed between and close to the power and ground...

Can confirm that all the changes worked as advertised. You guys are fast! Sorry, this was just poor verbiage on my part. The font size does change, I meant the issue remained independent of the font size used. I personally find the sliders a...

Playing around a little more, I removed the + sign with slider.setSliderPrint(menu1BacklightSliderH, 3, 0, false); And now get this when running the slider down to 1. Perhaps a clue there? This is Arial_16 BTW, though Arial_12 looks the same.

Looks like good progress is being made. Here are a few notes I made: Like @defragster, on my system it still requires the HX8357_t3n library. The st7735_t3_font_Arial.h is present in the beta 5 release, so not sure why it isn’t finding it, but...

I tried the files in #49. Still had a number of compiler errors. Looking at your compiler log in #47, I added the ILI9341_fonts-master to my local library and then the only compiler error was related to HX8357_t3n missing like @defragster got...

@mjs513 I just downloaded everything from #43 and tried to compile the .ino for the ST7796 with no changes. Also downloaded to my laptop and get the same compiler errors on that system as well. The #37 version still compiles fine. Since you...

With this latest version, I am getting quite a few compiler errors. Using the ST7735_t3 & ILI9341_t3 libraries in Beta 5 and latest 1.12.3 GFX library. In file included from...

@mjs513 just tried running your sliderM_class software. I played around a little bit with resizing the slider larger to get a better feel for the touch control on the small screen. Overall, it seems to work well. Looks like the slider value...

That is an incredibly clever fun project! The sheer number of elements it combines is truly impressive. Would love to see the build info on it.

Hi everyone, Here is a project I have been working on and off since covid, which I finally found some time to complete this summer... So I proudly present: S.A.R.C.A.S.M : a Slightly Annoying Rubik's Cube Automatic Solving Robot. Here is a...

Thanks @h4yn0nnym0u5e for keeping up the good fight! Received an update today that the chips are still expected to exit the factory on 9/30, so should be available in about 3 weeks.

Most capacitive touch controllers use I2C for the touch interface including the RA8875. This is apparently due to the fact that capacitive touch controllers tend to have fairly powerful 16-bit microcontrollers built in that reduces the amount of...

The FT5xxx type capacitive controller have more features like up to 5 finger detection and gesture recognition and so generally used on the larger LCDs like the 7" RA8875 as used on the Project System or Mark's setup. Smaller LCDs like the 3.5"...
