In SPI_DMA example how queue works for multiple slaves in single node , unable to understand from documents of iLLD.@User16286 

I am unable to debug the CYBLE-343072-eval-m2b.  How do I set the board up?  SW8 does nothing.  Makefile changes needed?  I am using ModusToolbox 2.4 and the Hello Sensor example.

I'm trying to understand, via the Architecture TRM, Registers TRM, and the PDL documentation how the Trigger Mux's connect to the PWM Trigger inputs.

I can see that there are 2 Trigger Mux groups, 2 and 3, that connect into the TCPWM's.  It looks like the TCPWMx_GRPy_CNTz_TR_IN_SEL1 register is used to select the trigger source for the START signal to the TCPWM.  It looks like I can chose between 139 possible trigger choices per figure 25-3 in the TRM.  It seems like I can pick the same trigger for each of the counters I might want to control.  I want to understand in more detail what is happening

1) Trigger group 2 vs Trigger group 3, which one is used and where is this documented?

2) There are 28 outputs from those 2 trigger groups.  How are they routed to the PWM's, where is this documented in the architecture or where is a register controlling this?

3) I cannot understand Table 29-2 in the TRM, there is no indication of what registers control this "selection"?

The PDL documentation shows that I can use Cy_TrigMux_SwTrigger to software trigger all my TCPWM's to START at the same time, but I am unclear how this occurs without understanding the mux connections from the Trigger mux to the individual TCPWM's.  Please help my understanding.

And note, this is for the 6xx4 family which is the Ver 2 style of TCPWM and muxing.

Hello there. I'm completely new to this microcontroller and I'm having problems in understanding how to program it from the provided examples.

I'm currently trying to conditionally set different GPIOs depending o the payload content sent by the host. Ideally I would like to be able to read the content of the DMA's channel buffer, which would contain which GPIO I want to set.

After finding out how to add headers to the payload I though I could simply access the memory location where the payload is and do a "if - then" statement using the content of the buffer as I expected. How would I go about doing this? Any direction would be rather appreciated. Thx in advance.

Hi,

I'm trying to change the heap size of XMC MCU using DAVE ... I tried to do that via the "linker_script.ld" file, but the size of the heap is defined as:

/* Heap - Bank1*/
Heap_Bank1_Size = Heap_Bank1_End - Heap_Bank1_Start;

I don't know where the numerical values of "Heap_Bank1_End" & "Heap_Bank1_Start" are defined

Can you please show where exactly in the linker_script.ld file I can change the stack/heap sizes?

Thanks,

I am using Creator 4.4 and I am trying to modify the API code for a existing component (TCPWM_P4_v2_10).I imported the component in my design and modified name/version so as not to clash with existing component. Then I edited the API files, but when I added the modified component to my design and generated the application the program used the API files from the original component not the modified ones. I confirmed that this was true by modifying the originals in the library to check.

It appears list of API files and the path to use is coded somewhere in the component, does any body no where?

Also the Major and minor version numbers are also set inside the customiser code somewhere.

I presume this is a bug as you should be able to modify the existing components.

PSoC Creater 4.4 will program my CY8KIT-059.
However, Programmer 4.00 will not recognize the device.
However, Programmer will detect my CY8KIT-147.
What must I do to get Programmer to detect the CY8KIT-059 ?

Dear Engineers,

I'm using own application based on TLE9879 Eval Kit Hall Sensor example. Everything is working flawlessly but I'm unable to reach declared motor maximum speed unloaded and loaded.

Rated loaded speed : 18000rpm

Rated unloaded speed: 22-25000rpm.

Actual unloaded speed with eval kit is 17220rpm.

Below are wizard parameters. Most change was achieved by maximum Ki Kp duty cycles which make sense, but now I'm unable to increase speed even further. Voltage is as per motor datasheet. Current also.

Any hint where to look now? Thank you
