I'm writing a code to read from and write to 'serial SPI Frash memory' ,but i have an error
"serial_mem_test:48: error: 'unit16_t' does not name a type
serial_mem_test:135: error: 'unit16_t' does not name a type".
I can't solve the reason for this error.
Can anyone tell me how to compile this program.
==============here is my code========================
