Hi,
I am going to make a 6-axis robotic arm and I am going to control the motors with PLC.
I don't know how I should start and how to program the motors in order that the arm go to the right position.
And which coordination system I should use.
And etc...
Could you please help how I can start?
Dear Andre
I decided to use esp32 for my project as you commented.
Could you please let me know if the esp32-WROOM is a good choice?
I need to immigrate from Atmega 16 to esp32-WROOM.
Therefore I need to change my c code to the arduino one; for example i need to use timer interrupts,
ADC, and...
Thanks dear friend
I have to use wifi because of the customer order, therefore the Bluetooth doesn't work for my case.
Actually I need an app for setting variables for temperature and some other data in the app and then send the amounts of these variables for esp8266 via wifi.
Esp8266 should...
Thanks dear friend
The examples you send are about web server
How and where can I find some explanations and examples about ClientTCP1?

Thanks, I need to give my customer an android app, therefore I think it is better that we use ESP8266 as a tcp server not a web server.
First of all thanks for your reply,
Regarding to use of 2 microcontrollers I need that because I am going to have one PCB for both version (with and without WIFI)
Therefore I have a PCB for non WIFI model (with ATmega16) which is capable to add a esp8266-12f module in order to be a WIFI model...
Hi everyone
I designed an electronic circuit includes atmega16 to control some processes.
I am going to upgrade this system to a wifi model with a esp8266 connected to the atmega16 via uart pins. Therefore I need to create an android app to be able to send commands to the esp8266 in order to...
USART Interrupt Problem
Hi
I have a problem with USART interrupt.
I connect a Sim900 to USART of an Atmega8.
My program uses the USART interrupt for receiving SMS's and in the while loop of the program I use the getchar function to receive the SMS characters from RX port of the Atmega8.
The...
So many thanks.
Therefore I need to learn java first and then try to develop a GUI and the software for the purpose.
So how can I start that since I am just an embedded system designer not a Profesional?
I am working on a project that many sim900 modules are sending sms's to a gsm modem as a center of receiving sms's.
Sim900 modules send sms's as reports of the sensors connected to a microcontroller based circuit.
The SMS's are some texts like "error 1" or "Sensor 1 on " or "Sensor 2 off" etc...
My problem has been sloved by changing the name of the variable that the error was referred to.
It is strange because the same code was working in one of my other programs and I just copied it from that program.any way thanks for your reply.
Hi,i am using ATmega8 for a project to send and receive sms by sim900.
i use codevision and RX interrupt to get the input characters using getchar function.
char getchar(void)
{
char data;
while (rx_counter==0) wait_loop();
data=rx_buffer[rx_rd_index++];
#if RX_BUFFER_SIZE != 256
if...
reading received sms by Sim900 in codevision
Hi
Could you please help me how can I separate the received sms text and the sender No. From other parts of the SIM900 response to the +CMGR At command.
