Welcome to the C for AVR forum.

Please feel free to post comments, suggestions and any problems your having with the C for AVR's package.

Thats right ksor the MCLR will automatically have this property and reset the software when the 5v connection is broken. If you wanted you could add a software interrupt to happen upon a reset to process a certain bit of code but this is only if you need this functionality.

Hello ksor

Most of the Matrix team are away at a show this week but I will help as much as I can.

Flowcode should be more than adequate to make a program quick enough to reach 9999 in a minute.

You can use Flowcode to build your .hex file that will be sent via your PICstart programmer.

The MCLR pin is used only as a reset pin in the 16F84 / A. A switch can be added to reset the device by placing a push to break switch between +5v and a 1K resistor. The resistor the joins to the MCLR pin and a capacitor is used between the MCLR and ground to add stability. EG 5V----Switch----1K Res...

Hi Andy

Does the 16F84 still program and work if the type of controller is assigned manually in PPP. If it is not working then it would suggest a problem with the chip. Im afraid I only have 16F84A's here to test and you say they are being detected fine. Let me know how you get on.

The UART is based around the oscillator frequency. The microchip datasheet gives exact data on the speeds and error percentages compared to the clock speed. If an internal oscillator is used instead of a crystal there may be a much higher percentage of errors in the transmission. Also the internal o...
