ARM, RISC-V контроллеры

ну я пользовался. баудрейт не правил кварц такой же.. все работает.. кусок инициализации уарта UsartCfgPio(); //* Reset Transmitter & receivier AT91C_USART_PTR->US_CR = AT91C_US_RSTTX |AT91C_US_RSTRX; //* Configure AT91F_US_Configure ( AT91C_USART_PTR, MCK, AT91C_US_485_MODE, // Mode Register to be programmed AT91C_DBGU_BAUD, // Baudrate to be programmed 0); // Timeguard to be programmed AT91F_US_EnableIt(AT91C_USART_PTR, AT91C_US_RXRDY|AT91C_US_TXRDY); AT91F_AIC_ConfigureIt (AT91C_BASE_AIC, AT91C_ID_USART, USART_IRQ_LEVEL,AT91C_AIC_SRCTYPE_INT_HIGH_LEVEL, SamUsartIsr); AT91F_AIC_EnableIt (AT91C_BASE_AIC, AT91C_ID_USART); // Clock AT91C_BASE_PMC->PMC_PCER = (1<<AT91C_ID_USART); кусок инициализации клоков while(!(pPMC->PMC_SR & AT91C_PMC_MOSCS)) /* Wait the startup time */ { ; } /* Checking the Main Oscillator Frequency (Optional) */ /* Setup the PLL and divider: */ /* - div by 5 Fin = 3,6864 =(18,432 / 5) */ /* - Mul 25+1: Fout = 95,8464 =(3,6864 *26) */ /* for 96 MHz the erroe is 0.16% */ /* Field out NOT USED = 0 */ /* PLLCOUNT pll startup time esrtimate at : 0.481 ms */ /* PLLCOUNT 10 */ pPMC->PMC_PLLR = ((AT91C_CKGR_DIV & 14) | (AT91C_CKGR_PLLCOUNT & (10<<8)) | (AT91C_CKGR_MUL & (72<<16))); while(!(pPMC->PMC_SR & AT91C_PMC_LOCK)) /* Wait the startup time */ { ; } AT91F_PMC_EnablePCK(AT91C_BASE_PMC,0,AT91C_PMC_CSS_PLL_CLK|AT91C_PMC_PRES_CLK_8);//12MHz AT91F_PIO_CfgPeriph( AT91C_BASE_PIOA, // PIO controller base address 0, // Peripheral A ((unsigned int) AT91C_PA6_PCK0 )); // Peripheral B pPMC->PMC_MCKR = AT91C_PMC_CSS_PLL_CLK | AT91C_PMC_PRES_CLK_2 ; /* Selection of Master Clock and Processor Clock */ /* Select the PLL clock divided by 2 */ while(!(AT91C_BASE_PMC->PMC_SR & AT91C_PMC_MCKRDY));
