There's a thread about cross-compiling Mono at http://community.onion.io/topic/1945/cross-compile-mono-from-source-for-the-omega2-and-omega2. Mono should include the .Net or .Net core runtime.

PWM is very interesting to me because how it reminds me of AC.

@Guest yeah, I know I have been waiting to continue one of my projects on this answer alone...

@Chris-McCaslin When I was having this problem it was suggested by @administrators they would add drivers for more cameras don't know what happened to that process.

@Chris-McCaslin Try using any pins other than 20 and 21 since they run the I2C protocol. With regards to the servo, while fast-gpio is pretty handy, it's still software-based PWM. Anytime another process gets the CPU's full attention, the PWM signal will change. This will happen many times a second, so the PWM signal going to the servo will be constantly changing. This change in the PWM signal is the reason why your servo is twitching. Sorry, but your best bet for a non-twitchy servo is the Servo Expansion. Another thing, your servo accepts a high pulse of 1ms to 2ms in a 20ms PWM period. For the farthest position in one direction you would send a signal that is 1ms high and 19ms low, meaning a 5% duty cycle The farthest position in the other direction requires a signal that is 2ms high and 18ms low, so a 10% duty cycle And the neutral position would be: 1.5ms high and 18.5ms low, so 7.5% duty cycle

@Chris-McCaslin I bolded it, in the backticks it probably wouldn't become a hyperlink. Also, you're free to submit pull requests for existing articles

@Guest thanks!

@Lazar-Demin sorry for the late reply. I meant was that I want to have Openwrt or LEDE but without the OnionConsole or other extra software. As I could see LEDE project is only available for Onion Omega 2 and Omega 2+ but not for the original Omega. Maybe I didn't search on the right place but I couldn't find anything related to LEDE for the original Omega. I also try compiling but it failed at some point following this guide: https://wiki.onion.io/tutorials/cross-compile on the step 6a. Any help would be highly appreciated. Regards.

@Chris-McCaslin Ah, your browser may have cached the web code from the Omega. To get around this issue, you can try clearing the cache, or following these instructions to bypass the cache.

@chris-mccaslin Thanks! I've added it to the existing PHP GPIO article: https://wiki.onion.io/Tutorials/PHP-GPIO-Example

Your MCP4131 are bit careful for use with SPI. 3.3 Serial Data In / Serial Data Out (SDI/SDO) On the MCP41X1 devices, pin-out limitations do not allow for individual SDI and SDO pins. On these devices, the SDI and SDO pins are multiplexed. The MCP41X1 serial interface knows when the pin needs to change from being an input (SDI) to being an output (SDO). The Host Controller’s SDO pin must be properly protected from a drive conflict. Please check datasheet page 41. You can see the "Typical MCP41X1 SPI Interface Connections (Host Controller Hardware SPI) " wireing.

now i remember ... it has to be formatted as ext4 ... see Addendum Procedures. Just if someone else has a similar problem.

I think I got it, I updated the BravoPapa source to work with my layout which is way over complicated. https://github.com/Immortal-/OmegaGPIO/blob/master/gpio_demo.py the updated code.

Hi Chris, I will order a replacement shipment for your Omega as it should not have shipped with the testing firmware. I apologize for the inconvenience!
