thanks for the tip. after you said that, I realized I never changed the original code to read/write to the input/output I will look at the other examples and try again thanks

I tried to use the ucf file under logipi-gpio-exaple folder and got an error in Xilinx ISE. Anyone have a tip on using ucf file or configuring Xilinx ISE? I attached a screen shot of the error I get. thanks peter

I took a look at the drivers in logi-projects. I forgot to include the LogiPi ucf when I generated the .bit file, so I need to update the ISE project to use that. This is the correct one to use? https://github.com/fpga-logi/logi-projects/tree/master…

thanks for responding so quickly. that helps clarify things. I was able to follow your tutorial on element14, generate the verilog, generate the bit file in xlinix ise and load it with logi loader. The part where I got lost was running that code on…

Hi jonathan, I was able to follow that tutorial, run the simulation, generate the .bit file and load it with logi-loader. Dumb question, how would I call it from python after that? Looking at the other examples in logi-apps on github, I need to use…

Hi jpait, I already went through a few the basic examples on myHDL website. Right now I'm reading about converting to Verilog and VHDL. I thought of a couple of examples, though I haven't gotten that far yet. Simple decision tree - since I'm playi…

Agree, it would get tricky. I was reading up on Xilinx and Altera DSP yesterday. Even though I'm a newbie to FPGA, it was pretty clear the differences between product lines would mean code that works on Spartan DSP wouldn't necessarily work on Alter…

thanks for the tip. I'm still a newbie to FPGA. If I get examples working with myhdl, I'll post them on my github

Hi Jonathan, thanks for taking time to respond, and providing interesting details. I'll have to read it again and digest it slowly. In terms of cost, the LOGi camera is the same, but the way it connects isn't ideal. I would probably have to make …

thanks for catching that. here is the link http://electronsfree.blogspot.com/2015/01/experiments-with-computer-vision.html the images are color. Here is a sample image from my github https://github.com/woolfel/BrickPiJava/blob/master/projects/Java…

@mjones thanks for taking time to respond. The reason I ask is this. I'm working on a personal project to build racing robots using machine vision/computer vision. I tried OpenCV with raspi and picamera and found it too slow. I only need it to proce…

thanks. I'm just glad I figured out what was causing the issue. Though I don't think it was the dist-upgrade by itself that caused the i2c error. I suspect it is caused by disabling serial port login, which caused a communication error. the uart de…
