gary, thanks for conferming this is normal... i thought i was missing something because it was so far off, figured the whole point of a timer interrupt was that it was solid, the 8 bit versions are

i rewrote the code in another compiler just for kicks and its the same :( unsigned int i; void interrupt() { if(pir1.TMR1IF && pie1.TMR1IE) { tmr1h=255; tmr1l=96; lata|=1<<5; for(i=0;i<2;i++){} lata&=~(1<<5); pir1. TMR1IF=0; } } void main() { osccon=0xf0;//32Mhz ansela=anselb=0; trisb=trisc=255; tri...

martin, are there speed limitations on the timer1 or should i change the code... here is a calculator that i created from your equasion, from top to bottom prescaler 1,2,4,8 tmr1 calculator.fcf running th calculations for 50Khz i come up with the numbers on the top line when simulate, to conferm thi...

alright man, here's a project i did over xmas, i reduced it to show as example, in this one i have two 1938 chips, one sends uart instructions and strings for lcd the other 1938 chip receives the instructions and strings then updates display based on data and commands it received via 9 bit uart, if ...

are you using the current version of flowcode? if not what happens is it outputs on A0, in v5.5 the pin assignment was fixed
i use rc5 and its awesome

jordy, when i have rs232 talk from pic to pic i use 9 bit uart, in this way you have 0-255 in data and 256 to 511 in commands, can send a command like 300 to start sending data, then send your string, followed by a 325 which signifies end of string, i do this often, when controlling pwms and such i ...

think i might have it, initializes clears and returns to home prints number variables 0-9999999 prints string variables and termainates at last letter full cursor placement top line 0-15 bottom line 64-79 give it a try and tell me what you think? playing with strings.fcf here is a screen shot of pro...

you can make simple pwms that go to any pin on the micro http://www.matrixmultimedia.com/mmforum ... 26&t=11590

was playing around and realized i could break a string variable down like an array and send the characters out one byte at a time, check it out, sent two strings out to display, also to send numbers would be really easy as well since would be sending them out one digit at a time it would be number+4...

in most applications i have at least one switch attached to a port interrupt to abort operations, was wondering if there is a way to hack the interrupt so when a certain command value is received that it is processed from the isr instead of polling for new data received

yes, i borrowed those from the matrix c code cd, the datasheet for this display is really screwed up on that part, but it does send 0011 three times to get it into 4 bit mode then 0010 here is the snippet from the cd /* LCD initialize */ 0x33, /* Set for 4 bit operation */ 0x32, /* Set for 2 line LC...

this is for danny to show a simplier way of doing it :D --- hardware --- data0=c0 data1=c1 data2=c2 data3=c3 rs=c5 en=c4 wr=tied to ground(write only mode) lcd_masking.jpg in this fcf i took the lcd_byte variable and sent it to the output pins for data0-3 by useing bit masking, in binary bits 7-0 ha...

holy **** i figured it out, i had the pins in the wrong order (my bad) :roll: display flashes message on hardware below BIT BANGED LCD.fcf ... to add byte_to_nibble macro works best set up with delays as shown here connections are as would be shown in flowcode data0 d5 data1 d4 data2 d3 data3 d2 rs ...

martin, i was working on trying to do the same thing as post, i created a macro that takes a byte, splits to two nibbles, splits to 4 pins and sends high nibble followed by low nibble, when i looked at the datasheet on mine its confusing, was hoping to understand how to control and lcd, heres what i...

here's what i mean, this simi results for test are in the upper right corner of picture, the simi matches the description in help file, i take it the simulation is generic among all lcd types, in reality it should be listed as small,small bold, medium,large

thanks for testing that martin, your picture results are same as mine, but that doesnt match what the font is explained as or what the simi screen shows, i could have sworn i had the true font #3, last night i mapped everything out with the simulator then wanted to conferm on hardware which is why i...

can someone run code below with eb076 and tell me if the simi window matches the glcd, mine doesnt, im running v5.4...
sizes 1-3 are not correct to simi on my side

with the eb076, when i reprogram or disconnect or reconnect power i get a white screen, funny though the touch screen and the rest of the unit works fine, i can press the screen in places as if i were looking at the gui and the touch is processed and there is always proper uart signal when symptom o...

got it figured out with this link (thanks david) http://www.matrixmultimedia.com/resources/files/articles/MX031%20-%20Multimedia%20Files%20on%204D%20Eblocks.pdf here is flowchart glcd metallica.fcf i dropped in all 5 files on sd card that was generated here is picture of test https://dl.dropbox.com/...

i have been at this for hours and i am still nowwhere... im using page #14 of datasheet, i have a 2 gig sd card thats formatted to FAT, i uploaded 4 pictures into software and built project, it created some files i took the GCI file and dropped it into the freshly formatted sd card, opened up the da...

i thought there was a tutorial for uploading pictures on to a fat16 formatted sd card for the eb076,
i have a formatted fat16 and 32 cards, can someone sum up the steps it takes to do this?

wow, thats really cool, try this to see what i think of it FCD_LCDDisplay0_RAM_Write(0,14,31,0,10,0,17,14,0); i had no clue it was that easy in flowcode, after i read the web link i have a quicker way of generating the number code! download mikroc free version, there is a custom lcd char creation un...

Please make sure you have uninstalled ccs & flowcode and restart your machine and make fresh install of flowcode. You will get the effect of ccs deleted.

thanks, will have to do that in a couple days

same as tachometer project this one uses a 100khz tmr interrupt to measure and display rpm, generally when i do fast timer projects i use seperate chips to do this task like small 12f1840 chips and create a multiplexed 9 bit uart send receive lines so chips can exchange information when requested fu...
