about IIC slave

[desongli]

I need to develop the IIC Slave function by using a GPIO of the nrf51822, but the development on the KEIL with C is not enough, GPIO with C program is too slow to follow the IIC master’s communication . So I want to know whether nrf51822 can be develop with assembly language. If that is true, I need you give the assembly instruction set of nrf51822 , assembly SDK for KEIL, brochure and example program etc...

Thanks.

Hi,

The nRF51822 contains a ARM Cortex M0 CPU core. You need to read the ARMv6-M Architecture manual which has the instruction set and all the details of the ARMv6 architecture. We don't provide any SDK for assembly. You can see an example how to use inline assembly in C files for different compilers in the file bootloader_util.c found in \components\libraries\bootloader_dfu folder of SDK v11.0.0.

Best regards,

Jørgen
