Example 1:
SPI advanced initialisation on ATMEGA2561. In the manual you can read
Spi_Init_Advanced(MASTER_OSC_DIV4, DATA_SAMPLE_MIDDLE, CLK_IDLE_LOW, LOW_2_HIGH);
I you try to wrtie that you will get an error message that MASTER_OSC_DIV4 is not declared. After some hours of searching I found the correct parameters of that function by viewing the file SPI_const.mcl in the uses directory with an external HEX-Editor.
Spi1_Init_Advanced(_SPI_MASTER,_SPI_FCY_DIV4,_SPI_CLK_LO_LEADING);
is working but you won't find this in the manual!
Example 2:
The Ord function does not work anyway. Also the so called solution in
http://www.mikroe.com/forum/viewtopic.p ... hlight=ord does not work on ATMEGA2561.
Example 3:
Records.
Code: Select all
type
TFontInfo = record
CharWidth:byte;
CharHeight:byte;
CellWidth:byte;
CellHeight:byte;
end;
const
FontInfo : array[2] of TFontInfo;
Thats ok. But you have no possibility to initialize that array of records as a constant.
If you want to set that constant by adding a "=(" and you will get an error that the Expression is to complex. You can define it as a variable but then you have to set the values step by step. Wirh large records such as menus this is frustrating. See that exaple
Code: Select all
var Fontinfo: array[2] of TFontInfo;
begin
Fontinfo[0].Charwidth:=5;
Fontinfo[0].CharHeight:=8;
Fontinfo[0].Cellwidth:=6;
Fontinfo[0].CellHeight:=9;
Fontinfo[1].Charwidth:=8;
Fontinfo[1].CharHeight:=14;
Fontinfo[1].Cellwidth:=9;
Fontinfo[1].CellHeight:=15;
....
end;
Uses declarations:
I have a project where the main program is in Main.apas. This uses an other unit called grafik.apas. Both units are in the same project directory. and grafik.apas is located in the uses of main.apas. When compiling i will get the error "E-44 error occured while compiling grafik" "E-7 file 'grafik' not found". Why?
10 minutes ago it worked and also re-starting the program does not solve this problem.
Example 5:
PWM
Pwm_Init(PWM_PHASE_CORRECT_MODE, PWM_PRESCALER_256, PWM_NON_INVERTED, duty);
does not work on ATMEGA2561. It gives an Error "E-3 PWM_INIT was not declared" and I don't know how to initialise PWM on that controller. There is no help available.
