peepo/verilog_tutorials_BB: verilog tutorials for iCE40HX8K Breakout Board

verilog files for iCE40HX8K Breakout Board, build with IceStorm. These files are designed to be used with verilog tutorials see bottom-left here:

https://embeddedmicro.com/tutorials/mojo/creating-a-project

Install IceStorm: http://www.clifford.at/icestorm/

Clone the repository:

git clone https://github.com/peepo/verilog_tutorials_BB

read pages 5-6
NB: make upload uses -S to program SRAM so please remove J7 jumper and rotate 2xJ6 jumpers

Build one of the examples:

cd project
make
make upload

Projects:

Project	name	brief	description
0	LED
00	LED	with +out
000	switch	tbc
1	button	button
2	Sync Logic	LED blink	1Hz
3	PWM1	LEDs fade	4x, 6x with clk_50 from divider
4	PWM2	LEDs clk	8 LEDs fade in and out together ~1.5hz ?anomalous
5	PWM3	LEDs wave	8 LEDs fade in and out in sequence 12MHz
5_PLL	PWM4	LEDs PLL	8 LEDs fade in and out in sequence 25/48/96MHz
6	_tb1	testbench	basic and
7	_tb2	testbench clk	pwm for a couple of values
8	ext button	ext button	6,800Ω connects +ive to input and switch, -ive to other end
9	metastability	ext button	with debounce
10	PWM5	servo	arm swings through range: red-TP1 brown-TP3 orange-P16
10_vga	colour	VGA PLL	display bars 640x480
	Hello World	AVR	rely on AVR microcontroller in mojo, PIC is competitor
	----	--	mimas, XuLA2 have PIC18F14K50,
	SPI-	--	logipi may not have microcontroller? has spansion flash
	LogiCore	RAM	no project...
17	Timing	12Mhz	Total path delay: 84.10 ns (11.89 MHz)?
18	Timing_pipeline	12Mhz	Total path delay: 37.28 ns (26.83 MHz)
19	FSM	LEDs 2x	left_PWM & right_PWM, maybe also 5x states, ie forward....
	Memory mapping	AVR	ibid
	SDRAM	N/A	MimasV2possibly or XuLA2 SDRAM before writing to SDcard
	Embedded processor	N/A	skipping for moment.
