    [SOLVED] arduino leonardo stops transmitting once hdmi cable is connected to a screen

    I am using arduino leonardo for moving mouse pointer with head tracking using MPU6050. It works fine in general. But as soon as I connect an external lcd screen to my laptop via hdmi cable, it stops transmitting. (that is the TX led goes off altogether and the mouse stops moving) I am not able...

    Hdmi to lvds converter

    Hi all. I am trying to design my own hdmi to lvds converter since all the one's available in the market are around $35. I found a few documents about the same on TI website : **broken link removed** I also found an IC by Chrontel: **broken link removed** which ICs total cost to about $6 to $10...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    Yes I tried changing "CONFIG3" to CONFIG3. But it gave the following errors: ecgcode1.c:127: error: (195) expression syntax ecgcode1.c:127: error: (187) too few function arguments ecgcode1.c:127: error: (194) ")" expected ecgcode1.c:127: error: (195) expression syntax - - - Updated - - - Yes...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    Yes, thanks for pointing out the PORT -> LAT. I made those changes in the code. I also removed the stdlib and stdio headers. I am not using the __delay_ms() because if I give any delay above 40ms I get a "160: error: inline delay argument too large" I tried testing the given code with...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    I am attaching my code alongwith The problem I am encountering now is I am getting a warning: (358) illegal conversion of pointer to integer for all the addresses that I have defined And if I change that variable in the function to unsigned char* addr, then I get an error on the line SSPBUF =...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    So you mean to say something of this sort right? Is this code fine for accessing the registers of ADS1298 void SPI_Write(unsigned char addr,unsigned char data) { // Activate the SS SPI Select pin PORTAbits.RA5 = 0; // Send the address of the register to be accessed SSPBUF =...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    I am writing the code in C. So how should the instruction be? Like WREG = 0x4000; or how? Isn't SSPBUF to be used when writing the code here at all?

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    So when writing a code for ADS1298, I should first send the register address in SSPBUF followed by the data to be written to the particular register right?

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    Thanks for the information It really helped clear some concepts. But what I was looking for was a sample code for SPI communication to register addresses or something of that sort. I found one on this website: http://www.ermicro.com/blog/?p=1846 My doubt is here in the SPI_Write function, at...

    [PIC] SPI commands for PIC18F4550 with ADS1298 slave.

    Hi, I am trying to use PIC18F4550 to control the functions of ADS1298 ECG AFE. I read the datasheet of ADS1298 and saw the various registers used for different operations. However I am not able to figure out how the command is to be written in SPI. I searched google for different SPI tutorials...

    Does silk screen affect vias on the board?

    Hi, I am getting a stop mask error for placing a via on the tplace layer of another component. But I dont need to solder anything on the via. So do I need to change the placement of the via or placing the via on the silkscreen won't be a problem. I am attaching an image of the error for reference.

    Placement of batteries in the same plane on two sides of PCB

    Hi, In my design I need 4 batteries in total and hence I have placed two on one side of the PCB and two on the other side right below the first two. Because rest of the circuit isn't too big and the batteries are eating up too much space. But will that cause a problem in any way if the power...

    Routing for analog signals

    I have a doubt as to which is a better way to route for analog signals I have two options. Either I'll have to route it on the bottom layer in which case it'll be under another analog signal in the same plane. Or I can route it from in between two legs of an electrolytic capacitor. What is the...
