Re: 16(L)F178x family
18f26k80 has 12bit adc, its a 28 pin, this chip does have some funny configuration and does require the low esr capacitor. on the other spectrum microchip offers some spi based adc's wtih 8,10,12 bit resolution. when you search their site your looking for successive aproximation adc's. things that a...

Re: tmr1 and tmr1 ext osc
thanks, i didn't realize, a while back i discovered this problem and there was no fix, then i learned how to read datasheets, was adding tmr1,3,5 to libraries tonight and figured would post that

tmr1 and tmr1 ext osc
at least with 16f1939 when enable tmr1 it cuts out useage of c0,c1 pins... the problem is when select instruction clock as source it should clear bit 3 in t1con register... after enable tmr1 put this line of code afterwards to regain control of c0,c1 pins
Code: Select all
t1con&=~(1<<3);

ben: i was excited and forgot to initialize in flowcode.....im writing librarys for this by looking at datasheet and i found that any chip with 1800 in the name the sspif bit does not set when using it to determine message complete, this is kind of weird because its the way they instructed in datash...

12f1840 spi inop
is there anything special to do on this chip to get spi working? i wrote spi code for it and can't get it working either, i get one pulse on power on and thats it, did internet search and erratica search but shows nothing... can someone look into this for me have plans for it if resolved forgot to s...

Re: spi pic to pic
working spi master slave, this is a simple test but you can see how this can be expanded to send and process any instruction, and send back as many bytes the master is programmed to send.... it is important when sending message to slave that at least a 1ms delay is used here is master code 16f1939 s...

spi clock
in flowcode i can communicate with external eeprom and sram chips with spi clock set to idle low which would be mode 0,0... in c this works as well with the exception that the master can't read the slaves sent data correctly..... the only way using spi in c that i can receive information from extern...

Looking at the app and your algorithm , there are some clever programming skills (by the both of you)! thanks man,... the c code was the algarithm that i wrote for rod using mikroc,... he copied it over and made some mods so it works with his compiler, then over the next week he added all the cool ...

tmr2 (computer app)
to demystify the tmr2 interrupt, a friend (rod maher) and i came up with a tmr2 calculator computer app that will speed up project development time and increase confidence in using this interrupt, here is a link, PICTimer2Calculator.zip or direct link: https://dl.dropboxusercontent.com/u/10367218/PI...

Can we just do it without C in simple way? yes, sorry about that, i thought that was what you were going after, i noticed the mikroc coding, to toggle a bit just make the pin or port an output with a flowcode output icon, then use this if your gonna toggle the bit on B0 latb^=1<<0; don't know if th...

first you have to turn off the analog selects, then use tris to make pin output, then use toggle like this, this is just to toggle b0 pin, with out any other pins accounted for anselb=0;// disable bport analog module trisb&=~(1<<0);// set b0 as output latb&=~(1<<0);// set b0 as low while(1){ latb^=1...
