  • Gist failed?

    void clkgpio::SetPhase(bool inversed)
{
	uint32_t StateBefore = clkgpio::gpioreg[GPCLK_CNTL];
	clkgpio::gpioreg[GPCLK_CNTL] = (0x5A << 24) | StateBefore | ((inversed ? 1 : 0) << 8) | 1 << 5;
	//clkgpio::gpioreg[GPCLK_CNTL_2] = (0x5A << 24) | StateBefore | ((inversed ? 1 : 0) << 8) | 1 << 5;
	clkgpio::gpioreg[GPCLK_CNTL] = (0x5A << 24) | StateBefore | ((inversed ? 1 : 0) << 8) | 0 << 5;
	//clkgpio::gpioreg[GPCLK_CNTL_2] = (0x5A << 24) | StateBefore | ((inversed ? 1 : 0) << 8) | 0 << 5;
}

    Well that would take care of BPSK modulation
