Welcome to the Infineon Developer Community

I need to use the cyusb3kit-003 SuperSpeed Explorer kit to develop a "logic analyzer" that writes from 16 bit parallel input to windows disk through USB3.   I have a USB2 device that takes data to a buffer, but the readout won't keep up with input.

It is simple.  I need an EXE file for execution under windows command prompt that takes data and writes to binary disk like my current unit.   I am not a programmer, so I need to find someone to do the programming.    I use a high level language to read the binary file and process it.

The web pages lead me in endless circles, and the associates list does not seem to know about the SuperSpeed device.   Short of learning binary coding which I do not have enough time to do,  I see no help. 

Dear IFXer,

In mosfet middle voltage process, may I know the following technology name are same process? because I saw the internal structure are very similar.

Split Gate (SGT)
Trench Field Plate
Shield Gate Trench

Hi I have a project requiring some form of electronic braking and I am using the TLE9879QXA40 board to power the motor. Is there any way using software or hardware to achieve this.

I have a posc6 cm4 app that when I allocate just a few hundred more bytes of static variables, the linker fails. 

The error is:

COMPONENT_CM4/TOOLCHAIN_GCC_ARM/cy8c6xx7_cm4_dual.ld:318 cannot move location counter backwards (from 08046878 to 08046800)
collect2.exe: error: ld returned 1 exit status

Ironically, the PROGBITS feature doesn't run if the linker fails, so you can't see unless you go back to the smaller size. When  you do it prints:

| .data | 0x0800228c | 7820 |
| PROGBITS | 0x08004118 | 1 |
| .cy_sharedmem | 0x0800411c | 12 |
| .noinit | 0x08004128 | 15572 |
| .bss | 0x08007e00 | 255208 |
| .heap | 0x080462e8 | 1304 |
| .cy_app_signature | 0x100fff00 | 4 |

The variable I am trying to grow in an uninitialized struct with an member array, so it should be in the .bss section which is huge, so I suspect that general understanding is wrong.  I can't figure out why the linker is failing or how to change it.   All the advice on this forum does not appear relevant for Modus Toolbox 2. 4

I am using the DFU linker script (dfu_cm4_app1.ld) from the BLE DFU example. 

Please suggest where to look and what to change. 

I am using GPT12_PWM_Generation_1_KIT_TC375_LK as the base firmware and test the example on my TC37X eval board.

Everything works perfectly.

I then tried to test the incremental encoder feature and I follow the document 

Hello,

I need to buy a compiler for the FX2LP18 USB microcontroller CY7C68053.  Can you confirm that the Keil PK51 is compatible with the CY7C68053?

Thank you

Hello!

I am trying to run PAS CO2 mini board on raspberry pi 3 using the python SMBus library for the i2c protocol.

I have a couple of questions regarding how to implement it.

1. My hardware setup is to connect four wires between the pi3 and CO2 mini board: 3.3v, GND, SCL, SDA.

Is this correct?

2. Referring to the Arduino application in the application note, I am setting the instructions step by step in python:

After reading ID, I wrote a code to read the sensor status (0x01). The return value is supposed to be 0xC0, but it appears to be 0xD0 (0b11010000.) In the register map description sheet provided,  4th bit means:

So, I decided to clear this bit by setting 1 to the first bit in the same register address, which is:

After that, I initially set it to idle mode. Then, I set the measurement rate to 10s just like what is shown above in the Arduino application and configured continuous mode by writing 0x02 to the 0x04 register address.

Then, I wrote a code to read the return value of the 0x07 register address, which is supposed to return 0x10 (0b00010000), which means data is ready to be read as written in the registermap description. However, for me, the return value is shown to be 0x02. This bit 2 indicates in the registermap description: 

Finally, when I tried to read the CO2 value, the combined ppm was 62454 something like this in decimal.

What did I do wrong?

I can share my python code tomorrow in the morning, but it is pretty much the same as the Arduino application shown above.

Any help would be appreciated.

Thank you,

Nakseung Choi.

I copied the code from the midi_server example over to a new MTW project and I can send Midi notes to iOS apps (Garageband, MidiWrench). However the server does not seem to receive any Midi events from the phone. I added LEGATTDB_CHAR_PROP_WRITE_NO_RESPONSE to the GATT db in the HANDLE_HSENS_SERVICE_CHAR_NOTIFY characteristic entry, and now the iOS apps do see that the device is capable of Input as well as Output.

I expected that when the client sends a Midi note or CC that the callback I registered (midi_server_gatts_callback) would get called but that does not seem to happen. Am I missing some obvious step?

Unfortunately, the MTW documentation is pretty light on tutorials and overviews 😞

Thanks, Norm

Hi,

I am developing a board with XMC1400 micro. Can you explain how to output printf() to one of the serial uart ports? I looked at some examples but they all use Jlink connection and DAVE IDE console.

Thanks,
