Bosses, when I was in the use of stm32f103, in writing your own file invokes the stm32f10x. H header file is submitted to the errors, D: \ Keil_v5/ARM/PACK \ Keil \ STM32F1xx_DFP \ 2.3.0 \ Device \ Include \ stm32f10x h (175) : error: # 101: "NonMaskableInt_IRQn" has already had been declared in the current scope
About 30 errors, are all about IRQ, how to solve ah,
Their use is stm32f103rct6 chip


This is I write my own code file invokes the stm32f10x. H
