Hello guys,
I have a doubt, I am new to ARM and need to learn architecture and in depth of ARM.
For this I am going through "ARM reference guide", book- but people explained on Assembly, not C. Even many books follow the Assembly, Why?
I am working on C but doesn't no assembly.
My question is...
As SIM300 works with UART protocol, use UART TX to send commands.Then what ever GSM replies read with UART RX and display the same on LCD.
smaple code:
tx_string("AT");
x=RX();
LCD_dat(x);
I have a project to work with three nodes communication and officials suggested to work with CAN protocol and suggested to work with MCP2551 and MCP2515.
Can any one provide me the protocol working and how to interface these IC's using AVR controllers.
I think you want to control other devices using TTL logic using microcontroller, here is the circuit I am attaching as a reference.
In this you can provide input at the base and take the output as shown in image.In place of switch you can use port pin/GPIO pin to control the output from controller.
I have worked with AT89S52 and used an external Flash(ISP) programmer, only hing is At89s52 doesn't have internal ISP(in system programmable), hence we need to get external programmer while comparing to atmega8,as it has internal ISP.
No consideration for crystal, if you want to work with 8051...
Re: Can 89S programmed using USBasp?
As according to the post for USBasp, it won't work with ProgISP, As there is no ISP(In system programmable) support in AT89s52. Here is the solution to dump to AT89s52 is purchase an IAP programmer which was working perfect for me...
