Guest pepevi Posted January 27, 2011 Report Share Posted January 27, 2011 Hi there, I just want to post what I'm working on, as comments are appreciated and needed. I've programmed a PWM module independent of the AVR Core so PWM is generated with VHDL, not with the timers of the Atmega103. Now I have 8 analog outputs on the Papilio, configurable via Arduino/wiring code (analogWrite as usual) and running synchronously. You can find the schematic here. This has led me to start working in a project where a user will configure its Papilio to meet his needs (PWM output ports, I2C, PPM inputs, etc.) and a .vhd will be generated (top_avr_core_v8.vhd, formally). This uses the full power of the FPGA as each pin is totally configurable. So this comprises some VHDL modules, a script/app that generates top_avr_core_v8.vhd and an Arduino library to command the modules. Link to comment Share on other sites More sharing options...
