Hello to all returned in this topic,because I managed to make the keyboard of 6x4 and stayed put here to anyone who is interested in implementing.tested with the keyboard of the proteus Calculator and worked is only adjust for convenience of you.Thank you all

Do you have any fireworks that you can use to use this microcontrollers WITH FLOWCODE .someone can give me a suggestion?.Thank you all

Hello friends foristas like to know how I use for AVR the microcontroller AT89S51 or AT89S52,AT89S55,already that I have many here to spare and like to uses them,I know that there is no flowcode in support for this types of microcontrollers,however will have no fireworks for i uses it.

Ola Benj thank you for allowing me to reply I did what vc posted and gave certain .writes in the EEPROM GIVING OK. Thank you from my heart . My question now is how does the EEPROM Read protocol.Seeing the example that you did I cannot understand. 1 - Start 2 - Address of Block Read 3 - Transmit valu...

Protocol i2c is
start bit
ADDRESS OF BLOCK 0xA0
Address of EEPROM
Data
Stop bit
but I put to write at ADDRESS 0xA1 and nothing happens .

I used an example and then modified for my use and debuggo in Proteus.He writes in the EEPROM values at address 0 until address 0XF8 and then back to record at address 0,How do I write block 2 i.e. Record above address 0x100 for example .can help me

Hello to all foristas like the aid of you.On EEPROM 24C08 which has the coupler storage 4 block of 256 addresses .I would like to know how I do to write at address 2 when the Block 1 is full .

Thank you LeighM managed to decompose and reassembly of the variable.Thank you even

LeighM Thank you for answer me and at the same time lighten my mind.Was with doubt and you answered me so clearly.Thank You

I would like to decompose an undefined variable value 2660 and put into 2 variable and write to EEPROM foreign.If you want to check if this value is there in the EEPROM I get the variable and remonto.My doubt is how I do this decomposition and reassembly of variable .someone can help me

Ola friends I am trying to make a project with microcontroller PIC 16F877 and this project consists in record a number in the eeprom foreign 24c08,number as these 2600 until 2660 and then make the comparison if the numbers are certain,but doing test with the own internal microcontroller eeprom VI th...

Ola Benj thank you for allowing me to reply .very interesting and util this mode of use .I will examine more macro to learn to do this .Show of ball . Thank You

Hello Benj i am by examining your example and vi that you do not declare any variable and yes names such as .date and .command vc can explain to me what this means.because I thought that interesting this influences anything .

I will examine a little more to learn how to use macros.Because is well easier understanding.Thank You

Good Night BENJ you is very good . Thank you for allowing me to reply I managed to do, but it was not that way as efficient and objective which you made ,because I am not so bao as agentkeys that knows very of flowcode .i did well

Ola a todos depois de muita insistência consegui fazer funcionar um transmissor do protocolo NEC que necessitava para um de projeto de interface que preciso fazer nesse ano.E como estava na duvida passarei o exemplo que peguei aqui mesmo no forum. START BIT = 9MS em LOW e depois 4MS EM HIGH LOGICO 1...

Ola medelec35 apologize for the delay,because it was on vacation of my work .thank you for helping me I will test it here and will answer for you

Ola giving response to the topic,unfortunately the LCD display(code ASCI) does not support letter alfanumerica Latins.Thank you for trying to help me
You can close this topic.matter resolved

I tried to make a simulation of the start bit and like that voçes analizasse if is correct.

My 1st doubt is about start bit.I have to put 1 bit in 9ms in low and the 2 bit 4,5ms in high.This this correct or does not ? Someone who has already worked with NEC protocol with flowcode can help me.

NReading a tutorial I understood that this protocol NEC consists of 4 bytes being that address / INVERT ADDRESS /Command /INVERT COMMAND,however like to an aid of how to implement it.

Ola a great 2016 for all.I wish once more to ask the help of you.I am already in the final phase of a project of interfacing of an appliance from karaoke to adapt in machines here in Brazil.now only need to do the typing of keys for Karaoke.I was studying on the protocol NEC and I would like to know...

Ola medelec35 Thank You for answer me.My hardware is proprio and will give a look to see be I make this way that VC has passed.

Ola kersing thank you for allowing me to reply I am using hardware proprio which fabriquei.I have already tried to use in flowcode 5 he gives error both ASCII OR MACRO MACRO STRING and always when I fake in proteus he lack any letter display. Example : Write STRING "MÚSICA CANÇÃO" appears " M SICA C...

I made a simple program and always lack letter on lcd displade .someone can help me .Thank You
