Re: Links to leafabs site in old comments are broken. Fix by replacing part of the url?

Thanks to you.

I thought there will be tons of broken links and they going to need some kind of mass replace in the BD, but actually the list was not that big.

Re: Links to leafabs site in old comments are broken. Fix by replacing part of the url?

Found those. I didn't search too deep, and covered only links to docs (saw some broken links to the leafabs forum). Also I think I missed 2 quotes in one of the last 3. I will report here if I find more. # - (number of broken links) - Link to the message 01 - (3) - http://www.stm32duino.com/viewtopi...

Links to leafabs site in old comments are broken. Fix by replacing part of the url?

Not sure if someone has asked before, but with the new leafabs site up, they also changed the location for the docs. Thus, all the links for that site in the comments are now broken, showing an error when you try to access. That's pretty bad because we lost important information provided by the user...

Re: UART or Task crash after X iterations using FreeRTOS

After some time I was finally able to continue in this project, and just came to say @edogaldo was right about the shared uart bettween tasks. After being sure each uart is used in only one task, the program started to run without any issue. After that I also switched from bluetooth elm327 to a wire...

Re: UART or Task crash after X iterations using FreeRTOS

Hi Luc, my guess is that you run into some race condition due to usart interrups handling. Consider that the starndard Arduino interrupt handlers are not thread safe out of the box, if you look at freertos usart samples you can see there are calls to special apis that make the interrupt handlers th...

UART or Task crash after X iterations using FreeRTOS

Hi, I'm looking for a hint on how to debug/solve a problem with the serial ports when using FreeRTOS. I need to test a DVR/LDW equipment for a car, that has to be feeded with serial messages each 200ms including the car Speed, RPM and turn signals. For the turn signals I simply use gpio and lower th...

Re: How to control Devices with Android-Part 1

I've used a HC05 module to interface Arduino with a cheap bluetooth OBD2 scanner to get Speed and RPM data from the car. While is not plug and play, I've found it easy to work with. Just an init code with AT commands wich you can save and almost just copy & paste to the upcoming projects. Thes rest ...

Re: USB HID

The download in the original post saved my life. I had to create a list of 500 1-wire iButtons (DS1990A), just selected the usb keyboard + mouse from the menu and paired it with the 1-wire library plus a little sketch to avoid all the hard work and common mistakes by wrong reading the small engraved...

Re: RPi Zero - for $5

same here with the chinese-is-my-first-option thing. Here in my country there is almost impossible to find stuff for electronics development. If you have luck and find the parts you need, then they are just too expensive. So the best option is to buy them on aliexpress or ebay and have patience wait...

Re: OrangePi-PC experience

I have two Orange Pi PC since a month, as well as some Raspberry Pi 2 boards. While I have not used them too much, I found them great for projects where you need a more powerfull brain to act as a master. Compared to a PC, the are cheaper, smaller, completly silent and use much less power. They are ...
