Hello, I program on keil µVision 5 and I have an error that I can not solve. There she is: TEST 1\TEST 1.axf: Error: L6218E: Undefined symbol SPI1_Transmit (referred from radio_spi.o) TEST 1\TEST 1.axf: Error: L6218E: Undefined symbol SPI1_waitTranfertComplete (referred from radio_spi.o).
I don't understand why this error persists. Someone can help me? thank you
"undefined" means that something has not been defined - so the solution to that should be obvious ...

It will persist until you fix it!
