PIC based Speed controller
This is a PIC16F870 based speed controller for electric radio controlled vehicles:
- PIC based, PIC16F870
- Uses PWM to control the motor current
- 128 steps resolution
- Features low resistance MOSFET for large currents
- Includes a MOSFET to short circuit and break the motor
- Very easy to use:
- Connect it to your R/C Reciever with standard R/C connector
- Connect the battery to the two dedicated pads on the PCB
- Connect the motor to the PCB
The code is written in MPASM compitable assembly. All files are found on this page: http://www7.brinkster.com/strombom/ESC/index.htm

Appologies in advance.
I'm new to this PIC programming. I am running windows NT service pack 5 on a pentium s motherboard. Bios setting is SPP. Im using MPLAB IDE version (5.5) to edit and assemble the code. I am trying to use PICALL PRO windows version to Load the hex files into the chip. The software gives error at reset vector ooooh ("Code error"). Any body with what could be wrong. software really fully functional with PIC16f84 as advertised? (from: www.quasarelectronics.com/software.htm under kit 3117, 3081)'

I am working on a project with the PIC 16F873. I found that when the watchdog time is enabled, I can not write any data to on-chip eeprom. Is this a bug or is it documented somewhere. Also are there any tricks to disable the watchdog timer in code?'

Hi all!!!
I used to program a PIC16f873 with assembler, so when using variables in different banks I had to switch them using RP0 and RP1.
Now I have to program it with Hi-Tech C compiler, and I would like to know if I have to care about bank switching. Does the compiler recognise the location of every variable and automatically select the suitable bank????
I am going to use a buffer of 128 positions (the variables are going to be char), and this PIC just have 96 byte space in RAM data in every bank. Does the compiler divide the buffer and fit the parts into the different banks???
Thanks in advance.'
