AVR Embedded Tutorial - Various programmers: what changed

Revision 2 to 3. Removed lines have a minus sign; added lines have a plus sign.

Old	New		Line
1	1		## General
2	2
3	3		### Arduino IDE
4	4
5	5		The easiest way is to determine the necessary parameters for avrdude is to first program the appropriate AVR with the Arduino IDE.
6	6
7	7		Please refer to [[AVR Embedded Tutorial - Set up Lazarus for ATmega and ATTiny\|Set up Lazarus for ATmega and ATTiny]].
8	8
9	9		When programming the AVR for the first time, a boot loader is needed and this is best burned with the Arduino IDE.
10	10
11	11		If you want to change the clock frequency or other parameters, you also have to re-burn the boot loader so that these FUSE parameters are also re-written.
12	12
13	13		### Lazarus IDE
14	14
15	15		The parameters which you determined using the Arduino IDE are entered in Lazarus under:
16	16
17	17		- "Project \> Project settings ... \> Compiler commands \> Execute after" is entered.
18	18
19	19		The parameters look something like this for an Arduino Nano:
20	20
21	21		``` bash
22	22		/home/tux/Programme/arduino-1.8.5/hardware/tools/avr/bin/avrdude -C/home/tux/Programme/arduino-1.8.5/hardware/tools/avr/etc/avrdude.conf -v -patmega328p -carduino -P/dev/ttyUSB0 -b57600 -Uflash:w:Project1.hex:i
23	23		```
24	24
25	25		### Install Avrdude
26	26
27	27		If you install avrdude, you can shorten the starting parameter list for Lazarus a lot.
28	28
29	29		#### Linux
30	30
31	31		``` bash
32	32		sudo apt-get install avrdude
33	33		```
34	34
35	35		Note: When it comes to Linux package management, avrdude is usually somewhat older than the current version. Usually this is not a problem unless you are using brand new hardware.
36	36
37	37		### Shortened parameters
38	38
39	39		Since avrdude is in the search path, you can save the entire path specification. The line with avrdude.conf is also not required, since the default avrdude.conf is used, with Linux this is located at /etc/avrdude.conf.
40	40
41	41		``` bash
42	42		avrdude -v -patmega328p -carduino -P/dev/ttyUSB0 -b57600 -D -Uflash:w:Project1.hex:i
43	43		```
44	44
45	45		## Programming via USB
46	46
47	47		Most Arduinos are programmed via USB which looks like this for the following Arduinos:
48	48
49	49		- Arduino UNO:
50	50		- avrdude -v -patmega328p -carduino -P/dev/ttyACM0 -b115200 -Uflash:w:Project1.hex:i
51	51		- Arduino Nano, old boot loader (available on most Chinese clones):
52	52		- avrdude -v -patmega328p -carduino -P/dev/ttyUSB0 -b57600 -Uflash:w:Project1.hex:i
53	53		- Arduino Nano, new boot loader (will be used from early 2018):
54	54		- avrdude -v -patmega328p -carduino -P/dev/ttyUSB0 -b115200 -Uflash:w:Project1.hex:i
55	55
56	56		## Programming via ISP
57	57
58	58		Arduinos can also be programmed via ISP where the Arduino is connected to an ISP programmer via the 6-pin header. With naked AVR chips, this is done in the same way, only you have to solder the 6-pin connector yourself.
59	59
60	60		### USBasp
61	61
62		-	~~```~~
	62	+	```text
63	63		Atmega328p or Arduino Nano, with an aspISP programmer.
64	64		```
65	65
66	66		#### Linux
67	67
68	68		``` bash
69	69		avrdude -v -patmega328p -cusbasp -Pusb -Uflash:w:Project1.hex:i
70	70		```
71	71
72	72		#### Windows
73	73
74	74		The following driver must be installed <https://zadig.akeo.ie/> - USBasp driver
75	75
76		-	~~```~~
	76	+	```text
77	77		[Path]\avrdude.exe -v -patmega328p -cusbasp -Pusb -Uflash:w:Project1.hex:i
78	78		```
79	79
80	80		### Arduino ISP
81	81
82	82		Homemade ISP programmer with an Arduino, according to these tutorials:
83	83
84	84		- <https://flazer.de/blog/14/arduino-atmel-flash-station> - with control LEDs
85	85		- <https://playground.boxtec.ch/doku.php/arduino/attiny> - without control LEDs, or search for "arduino attiny isp" .
86	86		- ATTiny2313 with modified Arduino as an ISP programmer.
87	87
88	88		``` bash
89	89		avrdude -v -pattiny2313 -cstk500v1 -P / dev / ttyUSB0 -b19200 -Uflash:w:Project1.hex: i
90	90		```
91	91
92	92		### Release the USB port
93	93
94	94		The USB port may be blocked which causes the following error to occur:
95	95
96		-	~~```~~
	96	+	```text
97	97		avrdude: Warning: cannot open USB device: Permission denied
98	98		avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp'
99	99		```
100	100
101	101		With Ubuntu-based Linux you can fix this by installing AVRdude as follows:
102	102
103		-	~~```~~
	103	+	```text
104	104		sudo apt-get install avrdude
105	105		```
106	106
107	107		Note: a PC restart may be necessary.
