Re: TEK 4010/4014 Vector Graphics terminal DEMO

This is a test of alpha terminal mode. // A simple TEK4010/4014 Vector terminal DEMO // You need TeraTerm or Xterm switched to TEK4010/14 Emulation // // Use fast Serial over USB for best experience // // Shows alpha terminal mode // // Provided as-is, no warranties of any kind are provided :) // by...

Re: TEK 4010/4014 Vector Graphics terminal DEMO

@Chris: mind the tek terminal is not well suited for drawing filled primitives, as there is not such command afaik.. Adafruit is pixel-oriented, tek is vector oriented with the "draw a line from A,B to C,D" as the only graphics primitive.. Rendering adafruits demos with tek emulation may work, but i...

Re: TEK 4010/4014 Vector Graphics terminal DEMO

I may just add tek.print and tek.println which just call serial.print and serial.println Yes, that is ok. There is one issue with Serial.print - it cannot print the scientific notation - like: -3.45E-6. So we have to use something instead, which can do.. PS: the Tek terminal, when in alpha mode (Te...

Re: [STM32GENERIC/HAL] SerialUSB TX speed problem

It seems my above results (the tables with speeds) were wrong.. :evil: The Teraterm does not receive all 1mil chars with larger cdc buffer, but a fraction of it. The larger the buffer in CDC the smaller amount of data I get. Therefore the total time for TX was smaller and the TX speed was higher. I'...

Re: [STM32GENERIC/HAL] SerialUSB TX speed problem

The bigger buffers are fast, but TX looses the data :( While running the Tek demo against TeraTerm Tek emulator http://www.stm32duino.com/viewtopic.php?f=18&t=2336&start=20#p31835 the buffer sizes larger than 256 bytes show corruptions in the picture.. The libmaple usb works, not sure on the buffer ...

Another demo you may try or add to the library.

Re: TEK 4010/4014 Vector Graphics terminal DEMO

@Roger: Thanks! The next improvements could be: 1. introducing ie Tekplotv and Tekploth - vertical and horizontal lines with short addressing 2. Tekbox with short addressing 4. introducing the 12bit mode 5. when talking "a perfect library" - the most difficult part would be to create a mechanism for...

Re: Blue Pill that kills

What might the problem be? Bad voltage regulator? Bad pull up? I've checked visually for obvious things like shorts or bridged tracks, etc and can't see anything. Double check the component's values like resistor and capacitors, they could be shorted as well (or wrong values deployed, like 0ohm ins...

Re: TEK 4010/4014 Vector Graphics terminal DEMO

While deleting lines by overwriting them with the background ink works perfectly, overwriting the chars is leaving a weak artifacts like here Font Artifacts.JPG Interesting. Maybe ClearType related? Otherwise it works. No Tekcls() and static objects redraw is needed anymore :).. Update: no artifacts...

Re: Need advice: Metal detector with stm32f103

:lol:
How does it work under salty water? Is the signal of the same shape/timing as in the air?
