PSoC™ 5, 3 & 1 Forum Discussions

I seem to have a problem with creator trying to switch to a different device selection when it goes to program my project.

"Unable to acquire target device PSoC 5LP CY8C5888AX*-LP096" was received while trying to change the selected target.

I don't know why it wants to put an * at the end. CY8C5888AXI-LP096 is my selected device.

I have no problem building a project and writing the hex file using programmer, just the program button in creator.

Error: dbg.M0023: There was an error while programming the device: Connection with device lost during programming. Verify the device is connected and try again.

My target hardware is a Freesoc2 board. Any suggestion how to fix this?

hello,

I have a control register (8 bit wide bus) in my schematic, and I want to take that bus and run it to two places.  the first destination is just a straight connection bit for bit.  for the other destination, I want to send the control register's upper 7 bits to the destinations lower 7 bits (a right shift, effectively) and concatenate a different wire onto the upper input.  

something like:
 

assign destination_reg[7:0] =  {single_bit , control_reg[7:1]}

such that if single_bit is 1, and control_reg was 00110101, that destination_reg[7:0] would be 10011010

what is the best way to do this in the schematic editor?  I don't know how to manipulate the buses well enough.  I could make 7 series-pairs of not gates (effectively a buffer), and assign the inputs to the upper bits of the control_reg bus, then assign the outputs to the lower bits of the destination_reg, but that's really messy.

Hello,

I'm currently trying to open communication to the Sparkfun Razor 9-DOF sensor which has an atmega chip onboard and outputs sensor data via UART (TX/RX). I have set up basic open communication using a UART on the Psoc 5lp (Term) and a UART connected to the TX and RX pins on the sensor (IMU). 

The baud rate on the sensor is set to 57600. Tera Term and both UARTs are set to the same.

The main.c is as follows I have also posted the whole project. 

////////////////////////////////////////////////////////////////////////////

#include <project.h>
  
uint8 Ch;

int main()
{
    Term_Start();
    IMU_Start();
    
    while(1){
        
        if((Ch=IMU_GetChar())){
            Term_PutChar(Ch);   
        }
        
        if((Ch=Term_GetChar())){
            IMU_PutChar(Ch);
        }
    }
}

////////////////////////////////////////////////////////////////////////////////

The communication is there, but the output is gibberish. I see the following in Term after hitting the reset button on the sensor:

üüüüààüàüààüüüüüüüüüüüüüàüüüüüüüüüüüüüàààüàüüààüàüàüàüüààüààüüüüüààüüàààüàüüàààüüüàüüüüüààüàüààüüüüüüüüüüüüüüüüüüüüüüüüüüàààüàüüààüàüàüàüüààüààüüüüüààüüàààüàüüàààüàüüà (it looks different on tera term)

The worst part about this whole thing is that I got it working before, changed some stuff around, and can't get back there no matter what I try.

Any help is appreciated. Thanks!

I am not sure the best forum for my question. I am looking for a contract PSOC 5LP "expert" programmer that either has experience with Decawave or capable of helping port some C code from another processor to the 5LP.

The device is a RF transceiver that interfaces to micro using SPI. The SPI code appears to be running and I can read write and read registers ok in the device.

My initial application is to simply get TX to RX working based on their example code.

The TX code appears to be working (The TX sent flags etc are all being sent correctly) but the receiver is not receiving anything.

Most of the job will involve looking into my code to see what I may have overlooked.

I am trying to use the UART module to decode the SBUS signal from an RC receiver. This signal is 100KBps Even parity and 2 stop bits. It is also an inverted signal so I added a not gate on the RX input. Since I could not select 100kbuad in the uart config, I am using my own 800Khz clock.

The device does not seem to decode this signal properly. In the attached image, the top trace changes state whenever I get an interrupt for a new character. The second trace is the signal from my receiver. To see that the uart was getting a signal, I tied the input to it to another output on the psoc and that is the third trace. The last trace is just the 800Khz clock.

You will notice that the first trace changes state after the first stop bit, not the second. I am not sure if this is a symptom iof the issue or not. I get an interrupt after the first stop bt every time so it seems like the uart is locking on to the signal fine.

The first byte has the value of 0x0F. This gets decoded correctly, however, all other bytes are not correct. The second byte shown should be 0x00 but its decoded as 0xbf. The next byte is 0x37 but is decoded as 0x13.

Is there an know issues using 8E2 format?

I am trying to read output from the Raspbery Pi to the Psoc (High/Low), Im doing a smart lock through bluetooth using the pi as the bluetooth compoenent. When a verified paired device is recognized i need to the pi to send out a 1 . With a DMM I am able to verify that the Pi puts out a 0,1 because it reads 3V=High and 0V=Low. When I try to read the output from the Pi  thorugh an if loop, the psoc does not work.

Any ideas on whats wrong?

I'm doing a simple operation on the Cypress PSOC 5LP 59. It uses SPI to communicate with a Raspberry Pi which sends a bunch of letters, and the PSOC 5LP blinks a light after it receives a certain letter. The PSOC stores the entire array of letters.

This does not work for some reason. It works if I use a buffer of 100 letters, and the A is the 95th letter or something. It works up to 400 letters or so (though it will be slightly sporadic sometimes.) But after that point, it won't work. For a buffer size of 1000, with the first A being at the 800th letter, the LED won't turn on. 

The SAME code, works with the 4200 with a buffer of 2000. So why does it not work with the 5LP? Its max array size should definitely not be 400 or so.
