Re: 89C420 Motor Control
I followed what you and the manual said, which is to put ASM51.EXE, MOD252 and yourcode.TXT file in the same subdirectory, and ran the program once. However, once I pressed enter, the DOS screen disappearred and no .hex file was created...
Is there any other easy way...
Re: 89C420 Motor Control
I am trying to use ASM51. But when I type C:\filename.txt and press enter, the program exits. Basically it exits whenever I pressed enter...
Re: 89C420 Motor Control
There is something that I don't understand.
What do you mean by "ordinary assembler" Do you compile it using Hyperterminal (I don't see the compile function in Hyperterminal), or uVision2 (I got a message saying there is an error opening my file).
How do you get the...
Re: 89C420 Motor Control
Umm... I tried Hyperterminal, but I couldn't type on that white screen. So I guess I can only transfer my .hex code using Hyperterminal. But before I can obtain the .hex file, I've to compile it using Keil uVision2 (??)
Ok. I tried to run and compile the following...
Re: 89C420 Motor Control
Thx.
In response to your post, I've the following two questions:
1. Is Windows Hyberterminal the only program I need to do this project? I'm asking this because I've previously read some posts that recommend Keil uVision2.
2. How do I create and send hex code to...
Hi,
Project: uses 89C420 to control two motors.
Goal: send high/low signal to 89C420 -> control motors' direction of movement
Circuit schematic: (picture attached)
Physical circuit: (picture attached)
Description: As shown in the circuit schematic, I used Max232 as the driver. I also...
8051 beginner circuit
Since Atmel DS89C420 has on-chip programmer and thus does not require external programmer, I think I might want to start with that. Most of the schematics/code I saw were for Atmel AT89C51. Any schematic/code for 89C420?
8051 codes
Hi,
I'm a beginner on 8051. I'm trying to use my Atmel AT89C51 microcontroller (I also have a Atmel DS89C420, if it's easier to work with) to start a simple project and teach myself about microcontroller. I also have Keil uVision2 installed as my software.
Does anyone have some...
free aec_isp.exe
I've a question with my 8051...
When I checked on the DS89C420 datasheet, I found out that the microcontroller only has 4 bi-directional I/O pins. That's not quite enough for my robot, since I need at least 5 (2 for left motors, 2 for right motors, 1 for distance sensor)...
8051 starter kit
Thank you SARCO~
Hey irfansyah, I was trying to get a copy of the AEC_ISP.exe software. They sent me an email containing AEC_ISP.exe, but I've trouble downloading it from my email... Do you happen to have a copy of the software? Could you post it on the forum? Thanks.
8051 simple project
If I use the type of 8051 that enables "In-System Programmable through Serial Port", then I guess I'll need to get a serial port, and one end will be connected to the serial cable, which connects to the PC to transfer the HEX code. What does the other end of the serial port...
8051 projects pdf
I believe mine is just a regular 8051 microcontroller that's not capable of programming through serial cable. So what specific type of external device do I need to program the 8051 flash memory with the HEX code? Thanks.
simple 8051 microcontroller projects
This might be a basic question. Let say I will program my 8051 with C language. How can I transfer the program into the microprocessor?
I used to use Parallax's Board of Education as my microprocessor, and BasicStamp as the programming language. What I...
8051 project
I've just purchased a 8051 starter kit, which includes a AT89C51-24 microcontroller, crystal, resisters, LEDs, etc. (Picture attached)
My goal is to learn 8051 and its applications. How can I get started?
