actually sim.gpt[1].port is being used as general io writing to the complete port 4 bits 1/2 byte at a time t the lcd data pins

the first 2 lines are actually defines, i just included them so you could know what pins they are on....

i saw an example somewhere where the guy was just using OSTimeDly(1) seconds

sim.gpt[1].port = h; high part of the byte
sim.gpt[1].port = l; low part of the byte

Can anyone give me a hand with this? i've put together some code but having issues.... this is on a mod5282 lcdRS J1[5] lvdE J1[6] void lcdSendCmd(char c) { int h=c/16; int l=c%16; lcdRS = 0; lcdE = 0; sim.gpt[1].port = h; lcdE = 1; OSTimeDly(1); //450ns min lcdE = 0; OSTimeDly(1); //5ms command 200...

Ok wired up a lcd #define lcdRS J1[23] #define lcdE J1[22] #define lcdD4 J1[25] #define lcdD5 J1[24] #define lcdD6 J1[27] #define lcdD7 J1[26] been looking for docs on how to write the data lines, instead of doing it by bits, for init could send 0x2,0xc0xc,0x1,0x6 instead of setting each pin and sen...

Ok, also sometimes while triggering interrupt 1 i get a printf for interrupt 2

the following works but it seems that the inteerupt does not clear i get about 50 or 60 printf statements before it stops, and if i hold the button triggering the interrupt it keeps firing and chrashes any ideas? INTERRUPT(IRQ1, 0x2100 ) { sim.eport.epfr = 0x02; iprintf("Interrupt1 \n"); }...

I was looking around, but i am a bit confused on how to set the gpio's

Yep but you can brick that too i have :s

QY-162A 8 bit parallel, would like to run it in 4 bit, also trying to figure out the pwm, whats the lowest frequency hardware pwm can do on the 5282?

Thanks

Hi I'm looking to interface a 4bit lcd, to my mod5282, this is my first netburner project moving from pics, can anyone help me out?
