Hi all I need a simple LCD Program code without any other tasks such as serial and GPIO co that I can see it clearly how it works. I need it badly. I am using MCBSTM32 kit board. Would be grateful if you have simple code for me Thanks
Hi Thanks for your prompt reply - Are you already familiar with electronics - particularly digital electronics? Yes I am
- Are you already a competent 'C' programmer? No not so, Just a bit like I know how to declare, build function, but i have yet to go further.
- Are you already familiar with embedded development in general? I am learning. I have worked with microcontrollers before but not so often.
- Are you already familiar with LCD interfacing in general? Yes sort of,
- Are you already familiar with the STM32? i am trying to be familar with STM32.
I am using Keil MCBSTM32 board
Q: Are you already familiar with electronics - particularly digital electronics? A: Yes I am
Good - so you can read & understand schematics & datasheets?
Q: Are you already a competent 'C' programmer? A: No not so...
There are some general programming books here: http://www.keil.com/books/genbooks.asp See also: www.accu.org/.../embedded_systems.htm And: publications.gbdirect.co.uk/.../ And, of course, any 'C' textbook!
Q: - Are you already familiar with embedded development in general? A: I am learning...
There are many online resources; eg, http://www.embedded.com http://www.eg3.com
For specifics of using the Keil tools, you will need to refer to the Keil documentation; in particular the introductory material included in your kit, and: http://www.keil.com/support/man/docs/gsac/ http://www.keil.com/support/man/docs/uv4/uv4_ex_hello.htm
Q: - Are you already familiar with LCD interfacing in general? A: Yes sort of
The requirements of the LCD are completely independent of what is used to drive it - it makes no difference at all to the LCD whether you are using a PIC, an 8051, an STM32, an FPGA, discrete logic,or anything else!
Q: - Are you already familiar with the STM32? A: i am trying to be familar with STM32.
For support & details of the STM32, you need to go to the ST site: www.st.com/.../familiesdocs-110.html
You WILL need both the Datasheet and the RM0008 Reference Manual - and the ST page also has lods of application notes, examples, etc...
If you are using the ST Firmware Library, you will also need the documentation for that.
The Hitex "Insider's Guide to the STM32 ARM® based Microcontroller" is also available for download from www.st.com/.../familiesdocs-110.html
Keil's ARM-specific booklist is here: http://www.keil.com/books/armbooks.asp
Of course, I mean, "loads of..."
Thanks. Looks like it will take me time to learn. Ok Is that okay with you if I sent you a simple project to find out what I missed out?
#include <stdio.h> #include <stm32f10x_lib.h> // STM32F10x Library Definitions #include "STM32_Init.h" // STM32 Initialization #include "LCD.h" // LCD function prototypes int main (void) { lcd_init (); lcd_clear (); lcd_print (" HELLO DEMO "); set_cursor(0, 1); lcd_print (" http://www.keil.com "); }
When I compile the codes, no errors When I run, Nothing happened, no changes in the LCD When I debug, it stopped at lcd_init function using F11. To come out of the function, I used ctrl+F11, byt it could not come out. My friend says that there should a LCD code placed here in the main.c.
What do you think?
Clement
Yes, of course it will! It takes a great deal of practice and study - just like any other skill!
So what does that tell you?
Where do you need to look closer to find the cause of this problem?
"My friend says that there should a LCD code placed here in the main.c"
On what basis does he say that?
How, specifically, does he think that this will help?
