Hserout/Hserin max.speed

[Mugelpower]

do I need to connect both TX RX Lines on both pics crosswise because of some handshake signals or only one wire for sending from one pic to another? I didn´t find a picture of a master/slave configuration, exept Mister_e´s master/slave example wich is great but for serin/serout.
Hey, how about something alike for Hserin/Hserout Mister_e?

You do realize that the only major difference between SERIN/SEROUT and HSERIN/HSEROUT is that SERIN/SEROUT is bit-banged and HSERIN/HSEROUT uses the hardware USART module (if available) in the PIC...right?
Therefore, any example that works with SERIN/SEROUT, should work with HSERIN/HSEROUT, if properly configured...and it follows that you would then have to...Read the datasheets/manuals for the particular device that you are using.

Hi Skimask,

hmm...I can tell you the only thing I knew was that Hserin/Hserout uses the Usart and I hoped that because of this it could run the data transwer partially in the background .that means that the data-bits-pushing is performed with the minimum of software used to speed things up.

because I´m now thanks to your gurus of piclands help up to 20MHz I may use serin/serout with success....

But: serin/serout and Debugin/Debug worked only with 4 MHz and 4800 baud . any change to that and my recieving PICs LCD showed rubbish. We had that before.

I read cool examples with 112000 baud or so using debug, but that was on "strange" 18F Pics I can´t handle by now.

Maybe I have to switch to a "modern" usart-preferred-PIC with goes along with lots of tutorials or examples or so. The only thing about the usart in the 16F628A I found in the data sheet was "Usart:Y" and the codes for the TX and RX registers.

Tell you what: the learning curve is way steep for an oldschool mechanical engineer of 44 years in foreign language...
