Hi,

I see that P2.0 and P2.1 port pins are assigned for external oscillator and as well as they also assigned for alternate functions like for position detection channel in CCU6 timers in TLE9879xx board, but they are not in the port pins section. Can we solder two hall sensors signal pins out of three hall sensors for the BLDC motor control when we need to take use them as a CPOS (in CCU6) function?Attachment 2843

XMC1302 Flash Write, ERASE problems

≪ Previous: Multiple Communication in XMC1302

Maybe important to mention:
The latest user manual (Infineon-xmc1300-AB_rm-UM-v01_02-EN.pdf, page 224) suggests the NVM ERASE, that is not working.
According to the errata sheet this function is faulty and the ROM function should be used instead.

If you want to implement some low-level flash routines use the ROM routine for ERASE!

≪ Previous: SPI DMA XMC4400 automatic slave select update

Hi,

We want to generate a PWM output signal on one channel without CPU interaction. It can be CCU40 or CCU80, we have no preference.

The setup is:
1) Timer module generates pulses at a certain interval
2) DMA module is triggered by the pulses generated in (1). On every pulse, it transfers a 16-bit value to the PWM period match register.
3) The PWM module is running, but it does not update the period match register.

The problem is the shadow transferring mechanism. I can successfully update the PWM period match register with DMA, but according to the datasheet I also need to manually write to the shadow transfer enable register with the CPU.
Is it possible to trigger a shadow transfer without the need for CPU interaction?

I see that there is a connection between the POSIF module and the shadow transfer enable pin (hardware). Can I use this functionality somehow to address my problem?

The purpose is to play an audio file without CPU interaction.

Thanks
Rickard

Hello Infineon,

i'm curious about the status of MPU support in FREERTOS App.
I just noticed that the actual App supports FreeRTOS V9 - so MPU should be supported.
There's also a checkbox "Enable MPU support".

It doesn't change the linker script automatically, so i changed it manually (according to http://www.freertos.org/FreeRTOS_Sup...U_4709677.html.
Linker script now works without problems.

Do i have to copy them manually?
Or maybe is MPU support by FREERTOS App incomplete?

C167CR-LM GPT1 Core Timer T3 How does it work?

≪ Previous: FREERTOS App -- MPU support status

Hello Everyone,
Apologies upfront, I'm quite new to µcontrollor programming and just started to learn, so i probably got few thinks not right yet.

I've got questions about the T3 Timer. Today at my School I've encountered this timer for the first time but I'm not sure what this
does(we just scratched the Topic). I'm aware that the T3CON register controlles the timer and that this timer can run as simpler counter OR as a Clock.

My confusion starts when i use the Clock with an prescaler. According to the Manual If i have the CPU running at 20 Mhz
and I choose as prescaler a factor of lets say 256 my period will be 840ms with an resolution of 12.8µs. The Input frequency
would be then 78.125kHz.

What Number would then stand in the Register T3 every tick?
How is the period or where is the period applied to?
Where goes the Input frequency into?
What does the gated Mode or how does it work?

I hope some of you can enlighten me :)
