CC1350: I2C driver stop bit remove

Intellectual 1980 points

Part Number: CC1350

Dear friends,

My customer is using CC1350 I2C driver as master mode, reading a GPS module data.

They use TI-RTOS API I2C_transfer(), and need to remove stop bit after writing some data, since the GPS module needs it to.

Is it possible to do so?

Thanks!

Hi Yan,

The I2C driver is not in direct control of the start and stop as this s controlled by the I2C hardware itself, it is therefor not possible to simply "remove the stop bit". What GPS module are they using that want them to remove the stop bit?

Hi M-W,

Thank you for your reply.
Customer is using NEO-M8P GPS module.
So in this case, since stop bit could not be removed, anything else could be done?
Thanks!

Hi,

According to U-BLOX, the DDC should be fully I2C complaint (fast mode), where are you getting the information that you need to "remove" the stop bit?
