    ARDUINO USB HOST SHIELD And Other Questions

    I am finally getting my arty running and have written or modified existing VHDL code and configured it to the FPGA with great success. I am wondering if there are references upon connecting to the arduino usb host shield. I am also wondering how soon the arty A7-100 will be available. Sincerely, DC

    CAD drawing for Pmod shield?

    Is there a CAD model available for the Pmod shield? I'm using it with the Arty board (for which I do have the CAD model), and would like to incorporate both into an assembly so I can create a case. thanks! https://reference.digilentinc.com/reference/add-ons/pmod-shield/start
  3. I have been working with the Digilent analog shield for quite some time now, and initially, using its functions was an easy task and calling analog.read and analog.write in my main loop presented no trouble. Fast forward to today, every time I have called analog.write(the only analog shield function i need) in my main loop code, it seems to fail. The code function is called in a large menu setup and the code isn't the cleanest, but I have put in print statements both before and after the code is called. Both statements are printed in the Serial monitor, ensuring that the arduino is certainly reading the analog.write code, but whenever i test a channel, the output does not change from what was initially written out in the code's setup function. if someone could describe what is happening, that would be grand. please help.

    AnalogShield on Arduino Mega2560

    Hi all, because I was running out of memory on my Arduino UNO using the analogShield I changed to the Arduino Mega2560. As it turned out, the Arduino Mega2560 is not officially supported with the library from the digilent resource center. However, there is a modified lib on github which supports the Mega2560 almost flawlessly. Here is the Link: https://github.com/wespo/analogShield The only modification I had to do was to bend away pin 11,12,13 of the digilent analogshield. This way the 6pin SPCI port is used for SPI communication. (The mega2560 doesn't use SPI on pin 11,12,13) Ben

    Board Geometry for ARTY

    Are there dimensions available somewhere for the Arty board? I want to design a shield for Arty and need to know the exact locations of the headers. I see that it looks similar to Arduino headers, but a drawing or even Altium PCB file would really help! Thanks.

    Uno32 Shield Template

    Hello, I'm looking for an Altium PCB template for an Uno32 homemade shield who makes use of all the pins of the board. I would also be pleased with a "technical drawing" of the board which shows the spacing between the different connectors and pin banks so I could make my own template in case I couldn't find any. Thank you
  7. Hello everyone, and thanks in advance for reading this! On a current project, I’m working with a network of Arduino UNOs R3, each with an AnalogShield installed (to be precise, it’s 4 Arduinos+AnalogShields total, communicating over I2C). I immediately found a problem when I connected all their Vin ports together to a 12V power supply: they sourced too much current (my main power supply was reading more than 1 A!). So I quickly stopped that and tried connecting the 5V ports together to a 5V power supply. At first this was OK, but soon they started to source too much current again. I also tried powering one of them via USB and connecting all the 5V ports together… This works most of the time, but some times the 5V line’s voltage oscillates badly or they start sourcing too much current again... It's funny because sometimes things seem to work, and then stop working. I checked the health of all Arduinos and they are perfect. And I checked powering all Arduinos by themselves (no shields) both through their Vin and 5V ports, and that works with no issues... So it must be an issue with the AnalogShields... For the moment, as a temporary measure, I’m powering all of them independently through their USB ports, and connecting only their grounds together. But in my final configuration I’d like to be able to power all of them with a single power supply. Can anybody point to where the issue could be?
  8. Question 1: I changed a little bit to print out the value on passthrough code: #include <analogShield.h> //Include to use analog shield.#include <SPI.h> //required for ChipKIT but does not affect Arduino void setup(){ //no setup Serial.begin(9600); } unsigned int count = 0;void loop(){ count = analog.read(1); //read in on port labeled 'IN0' Serial.println(count); analog.write(0, count); //write out the value on port labeled 'OUT0'} I read values for all ADC pins 0->3. And I see that A0,A2,A3 read correct values with 32,000 for 0V, But for A1, this value is around 2200. Could you help me explain why that happens? Is that the Shield damaged ? Question 2: Is the default value around 45k, if I dont read anything ? COuld you help me answer ASAP ? Thank you
