This program exercises the I2C peripheral on Jellybean's LPC43xx. You can
scope SCL on P6 pin 3 and SDA on P6 pin 5. If Lemondrop is connected, LED1
will illuminate if I2C communication to the Si5351C on Lemondrop is successful.
Required Lemondrop -> Jellybean connections:
SCL: Lemondrop P7 pin 3 -> Jellybean P6 pin 3
SDA: Lemondrop P7 pin 5 -> Jellybean P6 pin 5
VCC: Lemondrop P4 pin 2, 4, or 6 -> Jellybean P17 pin 2, 4, or 6
1V8: Lemondrop P11 pin 2, 4, or 6 -> Jellybean P16 pin 2, 4, or 6
GND: Lemondrop P5 -> Jellybean P13

This is the smallest-possible example program using libopencm3.
It's intended for the Jellybean development board from the HackRF project:
https://github.com/mossmann/hackrf
It should blink LED1 on the board.
This example copy the Code from ROM to RAM and execute code from RAM.

This program exercises the SSP1 peripheral on Jellybean's LPC43xx.
Jellybean (connector)
P9 SPI
|-----------------|
| Pin2 Pin4 Pin6 |
||------| |
|| Pin1 |Pin3 Pin5 |
||------|----------|
|-------|
SSP1_MISO: Jellybean P9 SPI Pin6
SSP1_MOSI: Jellybean P9 SPI Pin4
SSP1_SCK: Jellybean P9 SPI Pin2
SSP1_SSEL: Jellybean P9 SPI Pin3
GND: Can be connected to P12 SD Pin1
PCLK clock source is PLL1 288MHz (from IRC 96MHz boot from SPIFI)
Freq = PCLK / (CPSDVSR * [SCR+1]).
By default (CPSDVSR=0 => Means MAX Divisor)
SSP1->CR0->SCR = 0x00 => CLK Freq 1.126MHz
SSP1->CR0->SCR = 0x01 => MOSI Freq 566.9KHz
...
Test Oscilloscpe:
SCR=0, CPSDVSR=32 => CLK 9.025MHz
SCR=1, CPSDVSR=2 => CLK 73MHz
SCR=2, CPSDVSR=2 => CLK 49MHz
SCR=4, CPSDVSR=2 => CLK 29MHz
SCR=8, CPSDVSR=2 => CLK 16MHz
SCR=16, CPSDVSR=2 => CLK 8.5MHz
SCR=32, CPSDVSR=2 => CLK 4.386MHz
SCR=64, CPSDVSR=2 => CLK 2.227MHz
SCR=1, CPSDVSR=64 => CLK 2.262MHz
Theory:
SCR=0, CPSDVSR=32 => 288MHz / (32*(0+1) = 9MHz
SCR=1, CPSDVSR=2 => 288MHz / (2*(1+1) = 72MHz
SCR=4, CPSDVSR=2 => 288MHz / (2*(4+1) = 28.8MHz
SCR=32, CPSDVSR=2 => 288MHz / (2*(32+1) = 4.364MHz
SCR=64, CPSDVSR=2 => 288MHz / (2*(64+1)) = 2.2154MHz
SCR=128, CPSDVSR=2 => 288MHz / (2*(128+1)) = 1.116MHz
SCR=1, CPSDVSR=64 => 288MHz / (64*(1+1)) = 2.25MHz

This program exercises the SysTick Interrupt of ARM CortexM4 on Jellybean's LPC43xx.
It also enable Cycle Counter to be used for accurate delay independant from Clock Frequency.
The Demo Use Cycle Counter and SysTick Interrupt to compute number of cycles executed per second.
The result is LED1/2 & 3 Blink with an accurate 1s Period (using SysTick) (Checked visualy and with Oscilloscope).
