Dear.

What is the difference between configuring full measurement as 0, or 1 in Lib_Meas_Fast_Sample function?

Hello!

I have designed a PCB that uses the SP490-01-11 tire pressure monitoring sensor. I would like to program the sensor but have run into some problems.

According to the documentation available here: https://www.infineon.com/cms/en/product/evaluation-boards/sp4x_prog_adapter/ the SP4X_PROG_ADAPTER should be used to program the IC, the programming adapter is currently not available to purchase anywhere.  Are there any alternative programmers I could use?

Based on the quick start guide I should be able to write code, compile and flash it to the IC using Keil μVision, but even after installing the plugin there is no SP490 in the list of targets. How can I add it?

Thank you for the help in advance.

Hi,

I used sp49 Sensor for my TPMS Application. Instead of RF we are using BLE for Communication. But my sensor power consumption is 0.9mA. Is it possible to reduce the power. How can  i  reduce the power Consumption

Dear,

i have couple of question on pressure sensor KP264 and usage of Diag1\Diag2 .

1- The Diag1 and Diag2 test shall be triggered  at start-up or after start-up by means of Diag SPI commands ? 

2- The use case UC2 in the safety manual mention a tsafety= 1ms.  Does it means that  the pressure measurement is available  1ms after the Acquire pressure SPI command?  (So opposite to the UC1 where the system shall wait 5 ms before reading the response of a Pressure SPI command).

We bought SP4X_DEV_KIT. I am trying to communicate with SP400-15-11 sensor and CC1101 SubGHz transceiver. I can see it's broadcasting on 433MHz. But i can't see the data packets the SP40 is sending.

There is very little information about SP40.

I use CC-Debugger with CC1101 and SmartRF Studio 7.0 from TI. I am sharing my SmartRF Studio 7.0 setting parameters in the attachment.

Which parameters is wrong? How can I build communication CC1101 with SP40?
