Display module will not receive data from the K64F MOSI pin

Hi guys,

Im trying to use the K64F to control the DM TFT35 107 display module (320x240, 256k colour depth) which works perfectly fine when using the Mbed LPC1768. My programme runs as intended using the K64F since I can view the responses through CoolTerm BUT for some unknown reason the display module won't display anything. So far I have:

- Used an oscilloscope to observe the MOSI signal on the K64F of which displays a 3.3V output. - Altered a register to enable a high drive strength mode, this increased the 3.3V to 3.6V (just in case)

I have seen another issue identical to this where the problem was solved by removing a resistor soldered to their display board but i do not have this option.

Basically I'm wondering if there's something I have overlooked hardware wise as this seems to be the case.

Many thanks,

Dan T.
