CCS/CC2650: Copy Character buffer data to integer type Variable

Tool/software: Code Composer Studio

Hello,

I am trying to copy buffer data(character type) to some variable which is integer type (uint8_t) .

Say I have 1 Buffer BUFTYPE txBufmesdata2[] ="78"   here 78 is stored or received  as char type.

I want to copy that 78 to variable say  H(int type ). I am getting error like incompatible with type.

Can you suggest any alternative method or way to copy data.
