Welcome to the Infineon Developer Community

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 followed this link to enable XMC_DEBUG/printf() function.

However, I got this error at the end. Can you guide me to resolve this? Thank you

Hi,

I have used IC IMC102 controller Motor to start the motor.

In the configuration MCE Wizard, I set the switching frequency (inverter =Fsw=6Khz & PFC= Fsw=55Khz).

But because the switching frequency of the inverter is 6Khz , the sound noise of the motor is high and this is annoying.

On the other hand, with the increase of the switching frequency of the inverter, ،Total CPU load becomes more than 90%.

I need frequency switching PFC 55Khz  and Fast control rate =1 ,

What solution do you offer to remove audio noise without increasing Total CPU load?

Best Regards.

How to solve?

Hi,

I'm using the PSoC creator 4.2 version to design the device CY8C6137BZI-F54 .

I have few iput discretes and few output discretes.

When I used PSoC5LP component I used status register and control register for that.

What to use for PSoC6?

AIMW120R035M1H

I am planning to use a 1200V SiC FET, "AIMW120R035M1H" to construct a full 4 FET bridge for 25kW usage.

But there is not a readily packed single gate driver that can deliver a minimum of 5A sink/source for 1200V SiC directly.

Is that means I need to find single >5A gate driver IC, or use two Half Bridge gate driver IC of >5A instead?

Please comment.

Hello

Is there any firmware available for BGT60TR13C  module to send out some information about the direction of the movement or angle values? 

I'm running presence_detection 1.3.0 but it seems it only transfers distance information not direction. Thanks in advance. 

I have a distance2go radar board. Today, when I want to use it again, I found that the software and firmware development package corresponding to the changed board cannot be downloaded. I hope you can get help. Send me the software and firmware installation package distance2go kit

Hello,

This question is related to the HX3 design discussed in this review.

The HX3 hub was manufactures as in the above mentioned design and it looks like it works ok, we use it to connect a USB camera module (AR0144) to the PC/Laptop. The camera module is USB 3 and has a micro-B USB connector, we use a micro-B USB to type-C cable to connect the camera module to the HX3 hub.
we have 2 types of micro-B to type C cable (see attached cable A and cable B), everything works good with cable A but when connecting the camera module to the HX3 hub using cable B we get a "USB device not recognized". we connected the camera module directly to the PC with cable B and it works good, we also tested the camera module with cable B connected to a commercial USB-3 hub and it also works good. 

any ideas what can male cable B not work with the HX3?

thanks,
