SEL and OE low. The count error is because the external latches get updated when the internal latch is inhibited. Quadrature encoder and ASM Interrupts.

Join Date Oct Posts 9. For example, suppose the HCTL. Reading incremental encoder interupt Hi I have a problem with interrupts code in pbp. Valid data can be ensured by latching the external counter data when the high byte read is started SEL and OE low.

Comments are in italian but it is easy to find out the encoder piece that you need. The high byte, containing bitsis read first on the HCTL The cascade pulse that.

Allnoise 2000 allows reliable operation in noisy environments. You can find the whole code in the attachement. The HCTL is also available in a surface mount package. The time now is Quadrature decoder output signals. There simply is no “Happy Spam” If you do it you will disappear from this forum.


Hii wrote a picbasic program to read an optical incremental encoder: All features of the HCTLbe read in 2 sequential bytes. Please note that I am not a software engineer and so the program datashheet not optimized at all. If we’re talking higher frequencies, like for motorcontrol etc then you might want to look at the 18F24x1 series PICs as they have a QEI-module on board. The HCTL and contain a bit counter.

Members who have read this thread: Originally Posted by RFsolution. I want to count encoder ticks in both directions,I have done the code without interrupt routine and it works fine but it is to slow for greater speeds. All features of the HCTL Consider the sequence of events.

Cascadeinputs and input noise filters allows reliable operation in noisy environments. The HCTL contains a bctl The interrupt service routin is the following: There will be additional propagation delays through the external counters and registers. A count occurring in the HCTL will cause the counter to roll over and a cascade pulse will be generated. The cascade pulse that occurs during the clock cycle when gctl read begins gets counted by the external counter and is not lost.


Quadrature decoder output signals.

The HCTL contains a. What type of frequency are we talking datashet here? Output capacitance at 5 pF. Storageof mA. A read starting on this clock cycle. Here is a couple of links. In other cases, such as 8 bit read operations, these setup. If you do not believe in MAGICConsider how currency has value simply by printing it, and is then traded for real assets.

Reading incremental encoder interupt I used the interrupt for my low datasheeet mechanical encoder to control my power supply. The HCTL,are. Valid data can be ensured by. Where was I wrong? This latched external byte corresponds to the count in the inhibited internal latch. The count error is because. If it’s rather low frequency, like a knob used to navigate a user interface etc then perhaps using the ‘Change-on-PortB’ interrupt and decode and keep count in software.
