Alcérreca Join Date: 2010-12-04 Location: SPAIN Message ID: 86 Hi, This is my first post here. I've just received my Papilio Platform and it is a great piece of hw. Arduino will be the starting point of most of the people to this platform so that's why I want to help improving the compatibility between the two. First of all, analogWrite is not yet implemented. I guess this is due to the fact that timers are always a big pain Before I start, is anybody working on it? Thanks. Jose.

One method is to use the SPI Wing for a SPI ADC solution: The other method is to use a Delta-Sigma DAC and a minimal hardware for Analog functionality as outlined in these two Xilinx Apps: http://www.xilinx.com/support/documentation/application_notes/xapp154.pdf http://www.xilinx.com/support/documentation/application_notes/xapp155.pdf On another note, I setup a nicer SMF based forum system. People were complaining about this GFORGE Forum system being to difficult to find things in. Each project has its own forum and it makes it hard for someone to easily identify the best place to put their post. In order to keep this thread from getting lost I'm going to move it over to the SMF forum. In a couple days I'm going to shut this GFORGE forum page down. Jack.
