Hello,

I would like to use the BLDC_SHIELD_TLE9879 with a raspberry pi instead of an arduino, should be straight forward given that the interface is just SPI.

arduino uses 5V logic. The BLDC_SHIELD_TLE9879 user manual does not comment on the logic level - does anyone know if the board is compatible with 3.3V logic?

Thanks,
Ralph.

Hello!

I have my Arduino Uno set up  to two BLDC_SHIELD_TLE9879s and have my motors with encoders connected to it. I'm trying to figure out a way to keep track of the position of the motors as they work together on a x and y axis. Is there a way to keep track of the position through the hall sensors? Or maybe a different way?

Please ask if you need more information and thanks for helping!

Hello, 

I am using a TLE9879 as a SPI SLAVE

The system has several SPI (slave) devices (LCD, Serial Flash etc, (FWIW: with different SPI clocks rates)

The TLE  is using P0_1 (configured as an external interrupt) to function as a 'slave select' so that it can be individually addressed.

The system is working but I have noticed that the  TLE occasionally seem to loose synch with the senders SPI clock (and just receives garbage (I have confirmed with an LA that the sender is sending correctly)

I have recently noticed that  that TLE is detection an Baudrate Error  (SSC2_CON.BE=1). As the clock is provided by the master I don't understand how/why the TLE slave  can even detect a baud rate error?!

Despite this I am setting the baudrate (SSC2_RB = 39 ) corresponding to a 500KHz SPI clock.

This (possibly) improves things but not much . (FWIW, I have experimented with SPI clocks from 500KHz up to 4MHz with similar results (SSX_CON/BE =1) still occurs frequently (say 20-30% of the time).

Can someone provide more context around this Baudrate error (besides what is in the datasheets).

How is is intended to be used.

What happens to the SPi peripheral when this bit is set?  It appears that often (but not always) 'garbage' (or 0xff) is received when BE is set.

How do I clear/reset the error?

What it the recommend way to drive the TLE as an SPI slave? (Any sample code would be very much appreciated)

As I said it works - but not 'well' (high comm error rate, unpredictable when it will glitch).

FWIW: The master talks to other (SPI) peripherals just fine.

I'm am running out of things to try - and advice would be very much appreciated.

Dear Infineon support team,

I am using TLE9842QX chip. Required example code for the EEPROM access. provide me the application note for

1. partition for EEPROM and FLASH

2. Pushing data to EEPROM

3. Fetching data from EEPROM

4. Clearing the EEPROM

Best Regards,

I try to add the example code of DMA_UART_TTY_EXAMPLE_TLE987X to my
project.

After setting the DMA options:

the header dma_defines.h is correctly generated.

But I get following errors:

compiling Main.c...
app\Main.c(69): error: #20: identifier "DMA_CH12_NoOfTrans" is undefined
char uart_tx_data[DMA_CH12_NoOfTrans] = "Hello World!\r\n";
app\Main.c(85): warning: #223-D: function "DMA_Master_En" declared implicitly
DMA_Master_En();
app\Main.c(187): warning: #223-D: function "DMA_Reset_Channel" declared implicitly
DMA_Reset_Channel(DMA_CH12, DMA_CH12_NoOfTrans);
app\Main.c(187): error: #20: identifier "DMA_CH12" is undefined
DMA_Reset_Channel(DMA_CH12, DMA_CH12_NoOfTrans);

-> dma_defines.h is not included.

and really there is no #define RTE_DEVICE_SDK_DMA in RTE_Components.h.

But I should not edit RTE_Components.h directly. How can I add
RTE_DEVICE_SDK_DMA, I can't find any setting in Keil uvison.

Volker

I am using TLE9845 for development, but found that when VS is lower than 4.9V, VDDC will drop to 0V and the chip will not work. But the Datasheet said "Single power supply from 3.0 V to 28 V". So how do I make the chip work at a voltage lower than 4.9V
