  1. my Arduino ide software serial monitor is showing like firmware version : 0x0 = unknown WARNING :Communication failure, is the mfrc522 properly connected ? scan picc to see uid, sak, type, and data blocks....
  2. Hello, I want to hook up a MPL3115A2 pressure transducer sensor and interface it with an Arduino micro-controller. But I have a question. I could set up the display and I can see it is working. The problem is that I get some random numbers, regardless of connecting the sensor or disconnecting the Arduino analog input from it. What might be the problem? Even when nothing is connected to the A0 or any other analog pin, I see the same behaviour. I appreciate any reply and help.
  3. I've wanted to do a little FPGA experimentation for a few years but have been spending my hobby time with SBCs and microcontrollers. Do you have some suggestions?
  4. I tried to start with FPGA programming, but didn't really get my head around it. I found the VHDPlus IDE and with the simple language, embedded libraries and other features it helped me a lot to make some cool projects Just in case someone has the same problem
  5. The Intel/Altera Max 10 FPGA seems a bit easier than most FPGA's. It has internal Clock, internal Flash and internal SRAM. Intel also deliver dedicated power solution for easy implementation. It also Comes with ADC, and even optional NIOS ARM configuration. It also has support for Different types of RAM, PCIE, and Flash memory. It offers up to 50.000 Logic elements. Can do some cool stuff with this thing. Still microcontrollers might be easier though. But it all comes down to the application you need it for I guess.
  6. I want to do a project about Xilinx FPGA Project. When I try to run my synthesis I get this error "There are no HDL sources in file set 'sources_1'. Please use the Add Sources command." - and under the messages tab i get this error. [filemgmt 20-2001] Source scanning failed (launch error) while processing fileset "sources_1" due to unrecoverable syntax error or design hierarchy issues. Recovering last known analysis of the source files.
  7. I'm trying to do a project about Papilio One Xilinx Developer Board and get started with FPGAs. I already have FPGA board, I want to connect it to monitor using VGA . coz no VGA port on my board, but there is FMC LPC slots. Can you tell me how did u do the connection from the slots to VGA. if u have documentation or picture plz send them to me Any help will be appreciated.
  8. I now have a papilio fpga board and although I've for now abandoned my previous project for now I would like to interface this to an external static ram as a learning exercise. So I was thinking of getting a static memory chip something like this one and making a small breakout board pcb for it (probably using seeed studio or similar to get it made), bringing out the pins to a female header row. I can then connect to my papilio using simple wires. Now, assuming my soldering is up to actually making such a board, is there any reason why such a board wouldn't work? I realise that having 30 or so wires connecting the two boards probably limits the speed I'd be able to use the memory at, but was wondering if it would work at all and if so what access speed I'd likely be able to get working? The purpose of this is mostly because I want to try it even if there are better solutions I could just buy... and to give me the hardware I need to understand making memory access controller in verilog. I don't expect this to be fast enough to generate video signals from but wondered what kind of speed I might expect to work with such an arrangement?
  9. For a personal hobby project I'm looking to make a small vga display using an fpga. I was thinking of making the display 640x480 pixels with one byte colour per pixel at 60hz (I believe those timings should work on any monitor?) By my calculation that means I need to read 640*480*60 bytes from the ram every second which is 18432000 bytes per second giving a time per byte of a little over 54ns per pixel. I'm looking at a device something like this for my memory. The datasheet indicates that it has an access time of 45ns so by my understanding it should be fast enough for my fpga to read the data from it. But I'd have to update it during the period when no data is being displayed as it's not fast enough to complete a read and write in that time. Are my calculations correct, and would such a device be suitable for using in this way? Or did I miss something?
