Re: HD44780

Nice to hear that it worked for you also. During testing I'v set the delay times after writing data to the display (in tdisp_lld) very long. These can be faster. I will correct that as soon as possible and send you the new file. I did not have enough time to test the 8-bit version. So that is untest...

Currently I'am checking and implementing the control features like enableing/disabeling the cursor. Turn on/off the blinking of the cursor. And scrolling and turning of/off of the dis...
