Re: [Pharo-users] From Roassal RTView to html

by Andrei Stebakov

Now it takes me to the right page, thanks! One small glitch though, looks like after mouse click the UI element gets grabbed by the mouse as if I pressed "click and hold". So the only way to dis-engage the mouse from the element is to refresh the html page.

Milton, thanks for the example. I wonder why the link it takes me to has an appended ".html" at the end like "https://twitter.com.html"?

I'll try to find if there is a way to embed a clickable interaction. Looks like since there is no response to the topic, I was wondering if it's a non-pharo/roassal way to do it or it's just not so many people tried it.

image lockdown/deployment mode

by Baveco, Hans

Is there a way to disable the programmer facilities and produce a locked image for an end user? I would be happy if I could at least replace the world menu with a custom menu. In the developers-list archives I only found an old discussion (May 26 2010 Image Lockdown/Deployment mode), without actual solutions. Maybe these are available now? TIA Hans

Re: [Pharo-users] Pharo things analog reads ?

by Denis Kudriashov

Hi Steven. I added I2C support <https://github.com/pharo-iot/PharoThings/releases/tag/v0.2.1> to PharoThings and WiringPi. Now you can ask the board instance for I2C connection: i2cConnection := board connectToI2CDevice: 4. And then read/write data using wiringpi functions like: i2cConnection readData. i2cConnection read8BitsAt: 16r32 "register". i2cConnection writeData: 16rAB. i2cConnection write8BitsAt: 16r32 "register" data: 16rA5. Also I added I2CDevice as superclass for simple i2c devices. There is example of accelerometer ADXL345. Look for details.
