heh, cant take any more cool pics cuz i had to sell the LCD for some $$$. ill probably be buying a glk12232-SM in the future, when money flows free once again

hope you enjoy hallis!!

here are some pics of my red modded GLK backlight. used a 10,000MCD superultramegabright LED from allelectronics.com. I filed out the white LED in the backlight unit, and then filed the red LED to a rectangle so it would fit in (but i kept the tip rounded). got some new polarizing film, and ta-da, p...

i like to use the Clean font, and a font i created from Clean, called "Clean Inverted", which is, you guessed it, clean, but inverted so you can use it on filled backgrounds. bascially i just loaded Clean into photoimpact 5 and did a batch invert and save, bingo. :) Could you contact me o...

What would be the best font to use for this display? Ie. a nice small one so that everything actually fits :D hi, i like to use the Clean font, and a font i created from Clean, called "Clean Inverted", which is, you guessed it, clean, but inverted so you can use it on filled backgrounds. ...

slight problem...

i can talk on I2C to the LCD fine, if i do it BEFORE i talk to the temp sensors. if i talk to the temp sensors first, get the data and then try to talk to the LCD, it doesnt work. i think i can work around this but i find it a little bit odd.
any ideas why this might happen?

the last font in Clean is 126. so i change the last one to 127, and draw the bitmap, upload the font. but how to get the the LCD to display the character. do i use ALT 0127 then, to display the sign in MOGD? what would i use in my code to display the character? decimal 127? edit: okay cool, it works...

okay, i found my problem. once again..ugh..lets just say im stupid. ;) my send macro routine would call an i2c_start, and then send the address, and then character, and then call an i2c_stop. for EACH character. this obviously but too much strain onthe bus with all the starts and stops. now the code...

hello i moved the GLK from the PIC serial port to the I2C bus. Only problem is that there is high error (characters are lost, garbled, skipped). I have the bus speed set for 100kBps (10khz) operation. I infact CAN connect to the GLK. my host unit ignores ACK. i have tried various delay times in betw...

SUCCESS!!!


i was correct! i needed to ground the 5th pin. it works now. thanks for your help and time

Are you working on TTL levels or RS232 levels on the PIC and the GLK? {edit} well, of course you are talking to the LCD at RS232 level, since you can talk to it from the computer... now the question is, are you talkingto it at TTL levels from the PIC? im not sure what you mean... PIC - TTL -> MAX23...

Switch your Rx and Tx lines... tried that when the LCD is connected to the PIC, it seems like it "locks" the PIC up. I have an LED set to turn on at powerup. with no LCD connected, it turns on fine. Whent he LCD is connected, the LED doesnt turn on. if i disconnect the LCD, reset the PIC ...

See, i have RS232 communication and I2C bus working now
temp sensor is Microchip TC74A5



now id just like to get it up on my GLK

ive tried CSS i think...maybe Hitech PICC or something...something you had to pay for and something i only had the demo of.

what is an ICE?

you have to make it hard for me here don't you, can't use C or C++... :o I will get the head engineer to look at it tomorrow morning with me... unless some one with assebly know how comes by... heheh i dont have any C/C++ compliers for PICs. sorry about that, heh. thanks for the superfast response ...

basically, i press the reset button on the PICDEM2 board to send the data.
