  1. Hi guys, To train the use of some macros I decided to update/improve a 16x2 lcd library (HD44780) that I adapt many years ago. Possible there are other libraries shared here, but I liked how I managed the configuration of ports and pins using some macros. The use of macros made the library more versatile and easy to adap to new projets without the need to change tons of code lines. The same simples example of use is runnig on MSP430G2553 (old value line launchpad) and MSP430FR2433 (the new value line launchpad). I hope it's useful. https://github.com/agaelema/LCD16x2_M
  2. Hello, I have being working on getting a 20x4 LCD (HD44780) working on the CC3200 launchpad and have not been able to get it working. I have found a few posts with partial code and partial libraries but have not been able to find an SPI or I2C example that works. Does anyone have a working implementation of the HD44780 on the CC3200 in either I2C, Serial or SPI mode? This is seems to be the closest I have found ( https://github.com/remixed123/CC3200-hd44780-lcd ) ... but I am unable to get it working. If anyone has been able to get this working, could you send me a simple "hello wor
  3. I'm looking for comments and suggestions to make this more generally useful. I have a pile of surplus character line LCDs based on the Hitachi HD44780 chipset. There are oodles of these available surplus, and really cheap, like $2 cheap. The probelm I see for most modern MCUs is that the LCDs are usually 5V I/O (at least for the surplus parts) parallel and chew up a lot of I/O slow so they require a bit of code to poll the display or timed delays to insure reliable operation. I'm not too motivated to reinvent the wheel, but all the options I've found seem to miss a lot. I've seen the Ad
  4. Hello, I have tested 2x16 LCD and works well. Included pll and systick routines. Thist project is wroted withotut any driverlib functions. It will be a good example for "bare-metal coding". https://github.com/fatihinanc/stellaris-launchpad/tree/master/1602_lcd HD44780 1602 LCD Connections; RS -> PB0 EN -> PB1 D4 -> PD0 D5 -> PD1 D6 -> PD2 D7 -> PD3
