cortex m3 değişkenler

[armsistem]

      Arkadaşlar selam , lpc1769 örneklerini inceliyorum , aşağıda uint8_t veya uint32_t şeklinde değişkenler var , uint8_t=unsigned int değerine mi eşit ? Böyle bir komut yoksa cortexm3 bir özelliğimidir , lpc17xx user manulinde de yok , programda herhangi bir yerde typedef unsigned int uint8_t; şeklinde bir komut satırıda göremedim.

Not:'EX33DS_LPC1768_XFi_C_Samples' inceledeğim örnekler.

volatile uint32_t UART0Status, UART1Status, UART3Status;
volatile uint8_t UART0CountOku,UART1CountOku,UART3CountOku;
volatile uint8_t UART0TxEmpty = 1, UART1TxEmpty = 1, UART3TxEmpty=1;
volatile uint8_t UART0Buffer[BUFSIZE], UART1Buffer[BUFSIZE], UART3Buffer[BUFSIZE];
volatile uint8_t UART0Count = 0, UART1Count = 0, UART3Count = 0;

Onların hepsi stdint dosyası içinde tanımlanmış. Bu dosyayı incelersieniz anlarsınız? unsigned int'e eşit değil unsigned char a eşit.Zaten aşağıdaki dosyadan anlaşılacağı gibi typedef kullanılarak c deki data tipler bu şekilde ifade edilmiş.
