To Alex:

16x2 Lcd displays driven by I2c are now fully operationnal under all targets (PIC16, ATMega, ARM), as you can see in attached zipped examples (PIC16F877 and ATMega328).

https://www.fabriqueurs.com/af...e-16-caracteres-interface-i2c/

A new special command allows users to activate /deactivate backlight from ldmicro ; see doc in LIBRARIES_FOR and attached ld file.
Don't forget to modify I2c address in I2cLib.c for AVRs and in I2cLib.h for PICs (Only one address to modify !!!) to match the one in ld file and in hardware module (generaly 0x27 by default).

lcd backlight is on :), i just set path for hi tech in flashMcu,that´s all i had to do, it seems easy, now i want to try words.


btw, is it possible to do like video link, i am using a serial lcd there or is i2c function in early development yet?

Hi Alex

Normaly you should be able to do the same as on your video with your I2C lcd.

Available commands for lcd 16x2 displays are explained in LcdI2cLib.txt in LIBRARIES_FOR:

- values between 0 and 0x10 are commands :
0x00= Erase display
0x01= Cursor home
0x02= Blinking display
0x03= Normal display

0x0F= Backlight off (if available)
0x10= Backlight on (if available)

Other values / functions can be added in libraries

- values above 0x80 are move commands to move cursor to line y, col x:
bit 7= 1
bits 6-5= y-1 allows 4 lines 1->4
bits 4-0= x-1 allows 32 columns 1->32

Example: 0xA5 = 1 01 00101 will move cursor to line 2, column 6

- other values between 0x11 and 0x7F are standard chars to display at cursor position


Examples (if I2C address is 0x27):

I2C_WR (0x27 255 'X') displays an X at current cursor position
I2C_WR (0x27 255 chr) displays chr at current cursor position if chr is a regular character (alphanumeric or puntuation for instance)

I2C_WR (0x27 255 0x00) erases display
I2C_WR (0x27 255 0x01) moves cursor home (line 1 col 1)
I2C_WR (0x27 255 0x10) sets backlight on

I2C_WR (0x27 255 0x83) moves cursor at line 1 (8) col 4 (3+1)
I2C_WR (0x27 255 0x87) moves cursor at line 1 (8) col 8 (7+1)
I2C_WR (0x27 255 0xA0) moves cursor at line 2 (A) col 1 (0+1)
I2C_WR (0x27 255 0xA5) moves cursor at line 2 (A) col 6 (5+1)

You can use a LUT to display strings char by char as in this example (replace 0x20 by 0x27).

Let me know if you need help.

thanks for your reply,first i wanted to try the hello world with backlight on, i think i did well:


https://www.youtube.com/watch?v=za1lHX-rFVM&feature=youtu.be


1)btw everytime i use i2c function there is a ldmicro error window that shows up only if it is named "I2C1" , watch video please, everything is ok, there is no problem just the window error it is a little annoying but it is ok

2) i have to always name ladder with no spacebar, no problem with that, what about if i don´t use lcd but in my librarie it is set 0x27, does is uses more memory?, i first tried using main library with address 0 i thought it would be generated with 0x27 as set in ladder, i had to set in main library 0x27, i think main library could be default 0 in address for lcd as it is now and then if i set in ladder 0x27 generated lib file that contains lcd library should be the 0x27 because i use lcd, it is only an idea.


My question is if i use backlight command for example how should i set it in ladder?, with an OSR for been used once or without osr?

thanks for your work, we have i2c in ldmicro :)

To Alex:

- Your hello is OK

- Ldmicro can manage several I2C busses on ARMs (ICD1, 2 or 3). On other targets its only I2C. If you modify ALL I2C names to be correct and SAVE the ladder you shouldn't be anoyed again.

- there musn't be spaces or minus (-) and generally no special symbols in folder / file names for compiling reasons

- to save compiling time, you can remove in each lib subfolder the libraries that you don't use in a ladder, EXCEPT UsrLib. c and .h

- to know if it saves memory, it may depend on the compiler efficency ; try and have a look at hex size ?

- if you never intend to user some libraries, you can remove them from LIBRARIES_FOR folder, EXCEPT Usrlib too

- it's difficult to set I2cLcd address in files from ladder because some displays have different addresses and another I2C peripheral can also have an address at 0x27 !
You're the only one to know that you're using this special I2C peripheral..

- to switch on / off backlight, it is sufficient to send the command once, but if you send the same command several times it shouldn't (doesn't) matter

I want to try 16x2 Lcd displays driven by I2c with Atmega, could you please give us the wiring diagram and the steps for making Hello program and the program.
Best regards
Thu Jun 6 2019, 16:22:26
(no subject) (by José GILLES)
To Ahmad:

To try I2cLcd 16x2, you must download the last version of ldmicro (5.3.1.0) and ARMGCC compiler from this site for instance:

https://developer.arm.com/tool...u-rm/downloads/8-2018-q4-major

Then connect your display to I2C bus (4 wires VCC,GND,SDA,SCL)
and follow explainations in:

- HowTo-Avr.txt in LIBRARIES_FOR directory
- LcdI2cLib.txt in LIBRARIES_FOR\AVR directory

Here's attached a working ld example for ATmega328.

Como reparar errores de programación. How to fix programming errors. (by Calubert)
Adjunto archivo de como hacer la programación correcta, de las entradas y salidas de LDMicro, de errores de programadores y no es un error de LDMicro (Programa).
Esto sucede porque los Bit de salida son 0 o 1, si en la salida le decimos que tenga el bit 0, nunca se activara en el bit 1 (en otras lineas), por eso tenemos que usar los (R) reles internos y sobre todo con nombres de variables diferentes.
Para mas detalles pueden contactar con migo por este mismo foro y daré las explicacion necesaria. no soy partidario de hacer escaleras ya que lo correcto es hacer uno mismo la escalera para luego no se tengan errores al modificar cualquier parte de programa ya que cada uno tiene una forma de programación.

Attached file of how to do the correct programming, of the inputs and outputs of LDMicro, of programmer errors and it is not an error of LDMicro (Program).
This happens because the output bits are 0 or 1, if in the output we say that it has bit 0, it will never be activated in bit 1 (in other lines), so we have to use the internal (R) relays and over all with names of different variables.
For more details you can contact me through this same forum and I will give the necessary explanation. I am not a supporter of making stairs because the correct thing is to make the staircase yourself so you do not have mistakes when modifying any part of the program since each one has a programming form.

Fichier joint expliquant comment programmer correctement, des entrées et des sorties de LDMicro, des erreurs de programmation et ce n’est pas une erreur de LDMicro (programme).
Cela se produit parce que les bits de sortie sont 0 ou 1, si dans la sortie nous disons qu'il a le bit 0, il ne sera jamais activé dans le bit 1 (sur d'autres lignes), nous devons donc utiliser les relais internes (R) et plus. tous avec des noms de variables différentes.
Pour plus de détails, vous pouvez me contacter via ce même forum et je donnerai les explications nécessaires. Je ne suis pas partisan de la fabrication d'escaliers, car la bonne chose à faire est de créer l'escalier vous-même afin d'éviter toute erreur lors de la modification d'une partie du programme, car chacun a une forme de programmation.

File allegato su come eseguire la corretta programmazione, degli ingressi e delle uscite di LDMicro, degli errori del programmatore e non è un errore di LDMicro (Programma).
Questo accade perché i bit di uscita sono 0 o 1, se nell'output si dice che ha il bit 0, non sarà mai attivato nel bit 1 (in altre righe), quindi dobbiamo usare i relè interni (R) e oltre il tutto con nomi di variabili diverse.
Per maggiori dettagli puoi contattarmi attraverso questo stesso forum e darò la spiegazione necessaria. Non sono un sostenitore di fare scale perché la cosa giusta è fare da soli la scala in modo da non avere errori quando si modifica qualsiasi parte del programma poiché ognuno ha una forma di programmazione.

Прикрепленный файл о том, как правильно программировать входы и выходы LDMicro, ошибки программиста, и это не ошибка LDMicro (Программа).
Это происходит потому, что выходные биты равны 0 или 1, если на выходе мы говорим, что он имеет бит 0, он никогда не будет активирован в бите 1 (в других строках), поэтому мы должны использовать внутренние реле (R) и более все с именами разных переменных.
Для более подробной информации вы можете связаться со мной через этот же форум, и я дам необходимые объяснения. Я не сторонник создания лестниц, потому что правильная вещь состоит в том, чтобы сделать лестницу самостоятельно, чтобы у вас не было ошибок при изменении какой-либо части программы, поскольку каждая из них имеет форму программирования.

प्रोग्रामर त्रुटियों की LDMicro के इनपुट और आउटपुट की सही प्रोग्रामिंग कैसे करें, इसकी संलग्न फाइल और यह LDMicro (प्रोग्राम) की त्रुटि नहीं है।
ऐसा इसलिए होता है क्योंकि आउटपुट बिट्स 0 या 1 होते हैं, अगर आउटपुट में हम कहते हैं कि इसमें बिट 0 है, तो यह बिट 1 (अन्य लाइनों में) में कभी भी सक्रिय नहीं होगा, इसलिए हमें आंतरिक (आर) रिले और ओवर का उपयोग करना होगा विभिन्न चर के नाम के साथ सभी।
अधिक जानकारी के लिए आप मुझे इसी मंच के माध्यम से संपर्क कर सकते हैं और मैं आवश्यक स्पष्टीकरण दूंगा। मैं सीढ़ियाँ बनाने का समर्थक नहीं हूँ क्योंकि सही बात यह है कि सीढ़ी को स्वयं बनाना है ताकि कार्यक्रम के किसी भी हिस्से को संशोधित करते समय आपसे कोई गलती न हो क्योंकि हर एक के पास प्रोग्रामिंग फॉर्म है।

to MGP:

thanks MGP, i compiled, i changed to 0x3E as you said, watch video please, but i couldn´t make it work with my servo, then i realized that it says #0x87, do i have to change to #0x8F?

https://www.youtube.com/watch?v=h_lqdc55b4g&feature=youtu.be

to Ihor:

when i press "OK" in mcu paramters window using MGP´s ladder, it says that 0 mhz crystal is not possible (it is 0.5Mhz actually) it changes to 16 Mhz, but if i press close window instead error window doesn´t show up, whatch video please:

https://www.youtube.com/watch?v=IxgmdS4Ru4A&feature=youtu.be





BTW : in https://github.com/LDmicro/LDmicro/wiki/Servo-PWM

it is ok to use arduino with 16mhz for servo motor control as Ihor did, it is like arduino board is making things easy, i don´t have to change the crystal, but in pic i have to change my 20 mhz to less than 819 kHz, why is it that pic16 can´t use for example 16 mhz for servo , in that way i could use other options, timers, serial lcd, with 16 mhz and servo like arduino does

For alex, It is not for UAR and write in the bit you want, note that you have to add to the lines 2,3,4. 128 and in line 0 do not add them.

NOTE you always have to place 128 and add the digit, example LINE 2 64 + 128 = 192 Decimal = hex. = c0 On line 1, it is not necessary to add the 128.

Para alex, No es para UAR y escriba en el bit que quieras, date cuenta que hay que sumar a las lineas 2,3,4

NOTA siempre hay que colocar 128 y sumar el dígito, ejemplo LINEA 2 64+128 = 192 Decimal = hex. = c0 En la línea 1 no hace falta sumar el 128.

Hi Alejandro

It seems to be a known bug in your version of armgcc toolchain
version "8 2018-q4" (in windows 64 bit )

https://bugs.launchpad.net/gcc-arm-embedded/+bug/1810274


You should use a previous version of the toolchain !
Or try to just replace this arm-none-eabi-objcopy.exe by the one taken in a previous version...
Or try to use a 32 bit version...

Let us know if it solves the pb ?
