NEW! RCL-1 RS232 Level Converter in a DB9 backshell
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...
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.+
