SPAMdimithriKILLspam at spamgmail.com asks:
Hello, I am looking to connect a MAX522 DAC through the PIC18F452's SPI interface and a PCF8575 I/O expander through the I2C interface. However both the SPI and I2C modules connect to the same pins of PORTC. Anybody knw away around this? Appreciate it if you cld help...
Regards,
Dimithri
hi there!
im using PIC16F877 as microcontroller to interface with the pc side via VB program, nevertheless the BasicComm i found it here is quite useful. I would like to know the way on how to send and receive frm the PIC16F877 so that it'll be a close loop control within the hardware and the pc. thank you +
SPAMbrentanoKILLspam at spamruhle.com asks:
I have an application that calls for a 19bit synchronous serial interface: clock supplied externally @ 1.2MHz. I am trying to use the Advanced USART in the 18F1320. I am trying to write out three consecutive 8 bit words, I use a timer to timeout during the middle of the third word to exit (since I only have 19 clocks not 24). The interface works for a short while but then gets stuck waiting to transmit the second byte. Does anyone have any suggestions? Thanks.

Robotics nuts!

Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.
The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow!
