Re: Let Us Know What You Are Doing With Flowcode

I am using flowcode to develop Production test jig that test product for functional pass/fail.
During test, the jig will capture test data and send it to PC through RS232. (may use ZigBee in future).

PC running Excel VBA will collect test data and save them in network server.

Re: RS232 out and bit bang

Benj,

have found the C Code for reducing delay time to get 9600 baud, now i can set the chip clock speed properly.

I have ordered (from Farnell) a copy of Flowcode 3 Pro to replace the student version that come with PICKIT2, hope it helps to ease on the comms programming.

Thanks

Re: RS232 out and bit bang

have able to make the the output at 9600 baud with below settings: 1. Internal oscillator at 8MHz (using C code). 2. Chip, clock speed, 710000Hz. (to offset the culculation of 1ms become 0.08875ms) Although the baud rate is correct now, the delay of 1ms is actually getting a 0.104ms due to the clock...

Hi everyone, I am new here, just bought from Farnell "PICKIT2 + Flowcode (Student licence)". After receive the item, then i realize it do not support communication. I tried the sample program provided by Matrix to bit bang RS232 data out using the PIC16F887 internal oscillator, i get max baud rate o...
