Hi,
Hi Hirata,
In really products, TSC2046E usually works with more powerful MCUs than MSP430, such as ARM9, ARM11 and Cortex A8. Personally, I tried connecting the TSC2046E with a Cortex M3 MCU via SPI for evaluation. Here are my comments to your two questions.
1) was TSC2046E connected with MSP430 through SPI interface?
Andy-san,
Thank you for your replay.
I have a real customer now.
If does customer want IP, do you have any condition?
Can you build IP to MSP430?
The current situation, our customer are considering to use CPU which is non-TI SoC.
If they want to integrate IP into SoC, do they need to make IP by their self?
Beat regards,

Hi Hirata-san,
The gesture engine is usually written in pure C code and platform-independent, which means it can be used to any MCU. Does the customer have singed NDA with TI? What's the volume for this project?
Andy
Andy-san,
I check that my customer have signed NDA with TI.
Volume is sevral humdred per year.
Could you tell me part number of Cortex M3 you used.
Best regards,
Yoshihiro Hirata
Hi Hirata-san,
The Cortex-M3 MCU I have tried is AT91SAM3U from Atmel. Actually, you can find an example project from Atmel, which has all the necessary code to control ADS7843/TSC2046E via SPI interface. Below is the link to this example project I uploaded.

Andy-san,
Thank you for provide me a example project.
But, I don't have any development kit of Atmel. So I can't build.
Could you provide me a MAP file?
And Could you tell me a MIPS of example project?
Beat regards,
Yoshihiro Hirata
Hi Hirata-san,
Sorry, I am not able to provide you with a MIPS example project. I suggest you port the C code from the Atmel project to your own project. I think you only have to complete the code for the SPI interface of the MCU you are using and most of the code from the Atmel project could be reused.
