Hi support team all.

My customer has inquired about initialization after power-on.

Does this device require initialization after power-on?

If initialization is necessary, please tell me the initialization procedure.

Best regards,

Higa

Hi Daisuke,

No the device does not require an initialization sequence. However, download of the respective drivers and a sequence may be needed to interact with host processor, send commands to TSC2046, and read touch screen data. Please reference the following:

Driver: TSC2046 WinCE 5.0 Driver

The link above includes an SPI communication code as a reference.

Additionally, the two E2E threads below give good guidance to chip function or application code:
