Hello,
I'm using WICED STUDIO 6.6. and CYW943907AEVAL1F.
I write a code that create some threads and these threads call malloc (and obviously subsequent free).
I checked so many times if malloc is followed by properly by a free and I found a correctly use.
I have the dubt that malloc is not thread safe: I mean that if I call a malloc in a thread and another thread is executing a malloc this can lead a crash.
I observe this crash because the processor resets.
Can someone help me ?
Show LessHi there,
I am confused about the field weakening settings for the IMC controller. It seems like there are two different settings affecting the field weakening controller.
1. In Solution designer setting-> motor control configuration>Control Regulators, there exists field weakening current limit as well as modulation threshold at which field weakening should get activated.
2. In motor control configuration>FOC and inverter setting, there is an SVPWM Over modulation enable/disable setting.
How do these two settings work together? In other words, if I disable field weakening in 1 above (by setting current limit to 0%), while disabling over modulation in setting 2, will field weakening controller be activated? If yes, at what modulation will it get activated (linear modulation range is until 86.6% motor voltage)
My observation during testing when I set a field weakening current limit of 10% (I also had SVPWM over modulation disabled) was that when I increased speed of the motor, the 10% limit was not respected. It is very strange that there is no documentation on the field weakening behaviour of the IMC in the reference or the software manual. Hence, I am forced to ask here.
Further question: In 1 above, is the field weakening current limit, the % of Id current allowed during field weakening?
Show LessDear Sir,
I need an AUX power under 10W ,3.3V application which Input DC Vin 150V.
I saw the Coolset product - EVAL-ICE2QR1765Z. (provide a voltage of 70VDC to 380 VDC depending on the mains input voltage.)
Input voltage 85Vac~265Vac
Input frequency 50Hz, 60Hz
Output voltage and current 5V 2A
Output power 10W
can I follow the EV kit of EVAL-ICE2QR1765Z and take off bridge rectifier BR1 to work with input VDC at 150V?
thanks.

I refer to someone else's project on the Internet, but after loading it in, I found that I can't find any of its header files, how should I add the path to the header files?

Show LessI set up a new project to test the MCU 4700. And I try to use P2.8 output a high level, because according to your user manual that P2.8 is not connected to any signal.
Here is my testing firmware:
However, it still does not work, I can't test a high level in P2.8.
Could you please tell me what' going on here?
Show LessIn the LE GATT Server Throughput Example, I found that the size of each notify array is 244u. I want to know if the maximum size of the notify data is 244 arrays. Because I want to notify 512 or 1024 each time to reduce the pressure on my streambuffer in FreeRtos. If notify supports arrays with a notification size greater than 244 each time, what modifications do I need to make to achieve arrays with a notification size of 512 or 1024 each time.

Hi there,
May i confirm if cyw20704 is BT/BLE 5.0 because some docs say it's a BT/BLE 5.2, thank you!
