    Question for the Actel FPGA igloo Nano eval kit

    Hi everyone, I am newbie to the FPGA platform and just start with an Actel igloo nano FPGA, based on AGLN-NANO-KIT with flashpro 3 programmer. My question is that what should I do if I want to assign the Topview Pin to specific I/O pin on broad? I try the drag the net into the port list and it...

    [PIC] Question of ADC on uchip

    Hi guys, A question about the dsPIC33 chip of uchip: Because the chip I selected only has one ADC1Buff, so I try to set the config bit(AD1CSSL)to switch between different Analog inputs, but here comes the problem when I switching between 2 different inputs, AD1CSSL=0x0006; AN1=ADC1BUF0...

    [SOLVED] problem with I2C on dsPIC33FJ

    Thank you for getting back to me. At last I found that the problem is caused by a simple mistake. A pin of chip is floating and didn't connect to the pad on board.(forgive my shabby soldering skill) Best Regards

    [SOLVED] problem with I2C on dsPIC33FJ

    Hi everyone, I encountered a problem when using the I2C module on chip. dsPIC33FJ, Mplab X IDE, the I2C works fine on a same board without power and peripheral circuit(power from pickit and just the ASDA and ASCL pins connect to the slave chip), but things changed after adding in the power...

    [PIC] question about ADC module on uC

    MPLAB X16, dsPIC33FJ Hi guys, Its my first time tried to use the ADC module and it really gives me some hard time, I've tried to use AN1 & AN2 as the analog input, 12bit accuracy, using scan method and only opened muxA, I saw the value change in ADC1BUF0(its fluctuated because its switching...

    Question about button design

    Hi, Thank you so much for the reply! the button push function works when delay is added in between the output and the read back. I think you are right, it is not a stable solution. Thank you guys again for the detail reply. Best Regards

    Question about button design

    Hi KlausST, Thank you so much for the reminder, guess I didn't ask the right question, I have already make the button work with pull up resistor, and what I am trying to do now is to implement the button push function without pull up resistor , with dsPIC33FJ chip, how should I do to set the...

    [Moved] embedded c for 8051 micro controller

    Hi abhishekzade, Sorry I should have add some explanation, sometimes I thought code explains better :P The micro-controller only runs the code in main function once, so anything you put into the main function will be executed at least once, in order to make your code loop and function none-stop...

    Question about button design

    Hello everyone, Just a simple question about button design, Do we always need pull up resistor based on the dsPIC33FJ chips? Can I just use the output port to set the pin value to 1 and then read back the value and see if the button is pushed?(I tried this in code, but looks it doesn't...

    [PIC] Question regarding compiler in MPLAB X 2.15

    Hi horse1, Thank you so much! Yes, I guess the compiler is not working correctly. I try to change to C30 complier under Mplab X and change the code that you suggested as well, and it works. Thanks again for the kind help!

    [PIC] Question regarding compiler in MPLAB X 2.15

    Hi guys, I've try to compile the AN1069 downloaded from the website, and here is what pops out from my IDE: Is it because the complier is not working (mpasm V5.57)? Or maybe the IDE isn't working? I've just re-installed it not long ago. Thanks ahead!

    [SOLVED] Can't match the chip dsPIC33FjMC804

    Hi Horace1, Thank you so much! I have switched from MPLAB to MPLABX 1.20 and setup the configuration bits, seems like the IDE was able to identify the chip right now. Connecting to MPLAB PICkit 3... Firmware Suite Version.....01.31.20 Firmware type..............dsPIC33F/24F/24H Target...

    [SOLVED] Can't match the chip dsPIC33FjMC804

    Hi ads-ee, Thank you so much for the quick respond! The chip should be dsPIC33FJ128MC804, I am using MPLAB IDE Verision 8.84.00.00. I have switched to the latest version MPLABX V2.10, it also gives the same message: "Target Device ID (0x0) does not match expected Device ID (0x62b0000)." Best...
