Hi there, I faced the problem of accessing both pwm channels and all of the four adc channels on the CON4 header at the mini2440 board. Unfortunately the included modules in the kernel that create the devices /dev/adc and /dev/pwm doesn't allow for that. Therefore I added two more drivers that are capable to do so. In the attachment you'll find a patch file (ext_io.patch) for the kernel Linux 2.6.32.2 (2010-01-13) 81 MB downloaded from http://friendlyarm.net/downloads. A sample application is provided as well, that has to be placed in /opt/FriendlyARM/mini2440/arm-qtopia/ in order to compile. Sorry, that all the comments are in german. I'm too lazy to translate them. Good luck with that, Stefan Behrendt Hochschule Wismar Germany
Extended pwm and adc driver
thank You for Patch.. Can you tell me how to apply the patch to kernel and will all channels of ADC works after applying patch??? Regards
I applied patch and AIN0 is working perfectly. I used http://friendlyarm-micro2440.blogspot.in/p/building-qt-projects.html This example for testing. How to select AIN1 using your driver and this example?? Regards
