I'm looking for some example USB HID device code for LPC2387 that compiles with GCC. The Keil example USBHID is horribly written, uses a lot of tricks with the _packed keyword inside type casts and such that breaks it when compiled with a different compiler. Aside from that the Keil example is also so ugly that even though it works fine in uVision it's just not very good code to base a proje...

Hello everyone I have a doubt that puzzles me on LPC1769 datasheet about ADC It says that there is a maximum analog input capacitance for the ADC (Cia). Is this the internal capacitance of the adc or the maximum capacitance i can connect to the adc input?? In http://www.nxp.com/documents/data_sheet/LPC1769_68_67_66_65_64_63.pdf In figure 29 (page 69) the capacitance (Cia) is connected outside ...

Hi all, 1. has anyone tried to implement a Virtual Com Host interface (CDC Host) or has anyone found a working example? I tried to modify a LUFA VCOM Host example but seems not working. 2. Has anyone tried to realize an USB Host application supporting different devices classes and detecting the right device connected so that is possible to redirect the EVANT callback functions to the rig...

Hi, I've made a little SD card audio playback board for someone using LPC1754. It all works fine and will play from any type and size of card. The board can be connected as a USB mass storage device. However on Windows 7 only, some SD cards are not readable by the PC. After much trawling through USB packets it appears that Windows is asking for the wrong sector when it requests the boot sect...

Hi, I'm trying to use CAN with some less-common baud rates but I'm not sure if my calculations are right. Crystal is 12MHz, using a 5x multiplier for a frequency of 60MHz. VPB divider is 1, so peripherals run at 60MHz. I've tested 500kbps and 250kbps, but would like to add 33kbps, 95kbps and 125kbps. I tried setting these rates but it keeps throwing errors onto the network. Good: 250 kb...
