Hi,

The files you attached did not have a uVision project associated with them. What you need to do is to use a project as a reference (for instance: ble_app_template) and add the files that you need.

If you are still having issues setting up Keil uVision, please see their getting started guide: www.keil.com/.../uv4.pdf

Best regards Håkon

Thx for your reply. I miss the keil uVision project file attach file. the question is : 1. I want to know how to add the peripherals(uart' spi 'rtc and Twi) on BLe. At the hal_twi.c is about the TWI peripheral file.it is use PPI controller by event.

Whether other peripheral( uart ' spi' rtc and twi) is same operator? can you give me more sample for me ?

2.at attach file(ble_app_uart_hasbro_rel1_715.7z) file. drv_gyro_mba222E.c mba222E_register_read(..) function. the line number 91 "transfer_succeeded = hal_twi_transfer(s_device_address, &address, 1, TWI_DONT_ISSUE_STOP);" my program always block there, and i have to fix to transfer_succeeded = hal_twi_transfer(s_device_address, &address, 1, TWI_ISSUE_STOP); why i have to change the TWI_ISSUE_STOP, it mean release the bus ?
