Okay, I think I might have solved this one. I didn't have the TRIS of the transmit pin configured as an output. I was under the erroneous impression the UART controller trumped control of any port...
I was originally planning on making 2 sets of MCP23017 circuits; 1 for input with debounce, 1 for output. But even with JLCPCB it comes out to $1 / PCB. I'd like to lower my cost more, and not have...
Use a logical analyzer to see what's coming out of the chip. Compare the output of the SEROUT2 to the output of the HSEROUT2 using the logical analyzer. You might think that your output is 115200,...
I've set the hardware config totally manually from the datasheet and via PBP defines (suggested in the supplementary document PIC18FxxK42_notes) and many hybrids of the 2 methods.
You might want to double check that you are setting the hardware communication correctly. I have used the code below to set the HSEROUT/HSERIN for the 18F4550. You might want to check the correct...
Hi all,
Having issues transmitting numeric data out from the 18F26K83 using hserout. No problems with the software serout2, but for some reason all my numerical data is corrupted for hserout ie....

I have been thinking for a while, how to put togeter a simple microstepper controller without using a ready made commercial driver.
At the end, I came up with this simple project capable to drive unipolar stepper motor in three different modes
FULL STEP
HALF STEP
MICRO STEP
The Pic micro used in this work is a Pic 16F628 a powerfull small micro with PWM capability. With this MCU plus a 74HC04 and a74HC86 the controller will produce 20 microsteps out of a nominal motor step.
An additional improvement of this controller, is the capability to accept travel commands of 24 Bits, wich gives to the user the possibility to send positioning profile of over 16 millions steps.
Controller accept commands via TTL serial port @ 9600,n,8,1 and return an (Ack) once the positioning profile has been completed.
Download the zipped MicroStepper.zip file which contains schematic + software + user manual
Also attached is a simple stepper controller example called Stepper_MK2.zip
