Function Documentation

int con_hdr_create_packages_list

(

)

Create a list of CON-HDR packages with pre-defined values.

The data in this list can be used in a combo box to select a pre-defined package.

Returns:

EXIT_SUCCESS when a packages list was created, EXIT_FAILURE when errors were encountered.

Definition at line 40 of file con_hdr.c.

int con_hdr_drc

(

)

Do some Design Rule Checking for the CON_HDR package type.

• check for total number of pins is even.
• check for number of rows is more than 1.
• check for number of columns is 2.
• check for allowed pad shapes.
• check for zero sized packages.
• check for a zero sized courtyard.
• check for minimum clearance between copper (X-direction).
• check for minimum clearance between copper (Y-direction).
• If no fiducials exist.
• check for clearance of the package length with regard to the courtyard dimensions.
• check for clearance of the package width with regard to the courtyard dimensions.
• check for any silk lines or texts touching bare copper.
• check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).
• check for a reasonable silk line width.

Returns:

EXIT_SUCCESS when no DRC violations were encountered, EXIT_FAILURE when DRC violations were found.

Todo:

Check for any silk lines or texts touching bare copper.

Todo:

Check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).

Todo:

Create attributes here.

int con_hdr_get_default_footprint_values

(

)

Look up default values for CON-HDR footprints.

Footprint values can be looked up by placing a question mark "?" in front of the footprint name.
If the footprint name is recognised the values will be loaded and the entries involved in the GUI will be updated accordingly.
Currently the following footprints are supported:

• ,

Returns:

EXIT_SUCCESS when default values for a footprint were found, EXIT_FAILURE when the footprint name was not found.

int con_hdr_set_gui_constraints

(

)

Set GUI constraints for the CON-HDR package type.

This function is only to be compiled for GUI targets.

Returns:

EXIT_SUCCESS when the function is completed.

int con_hdr_write_footprint

(

)

Write a CON-HDR pin through hole footprint.

The pin/pad numbering scheme of the CON-HDR package is:
for 2 rows
2 4 6 8
1 3 5 7
or for 3 rows
3 6 9 12
2 5 8 11
1 4 7 10
You get the idea for 4 or more rows.

Returns:

EXIT_FAILURE when errors were encountered, EXIT_SUCCESS when OK.
