16F690 serial communication tutorial. I need to change to make the code work for the 690. The IDE and the HI-TECH C compiler. The PIC16F690 has one or two. Pic16f690 Serial Communication C Code For Loop. Intended for an engineer who is new to Microchip products, this self-paced, online class provides an introduction to. Jul 18, 2016.

PIC 16F877 series normally has five input/output ports. They are used for the input/output interfacing with other devices/circuits. Most of these port pins are multiplexed for handling alternate function for peripheral features on the devices. All ports in a PIC chip are bi-directional. When the peripheral action is enabled in a pin, it may not be used as its general input/output functions. The PIC 16F877 chip basically has 5 input/output ports.

The five input/output ports and its functions are given below. When enabling peripheral functions, more care should be taken in defining TRIS bits for each PORT C pin as compared to other.

Some peripherals override the TRIS bit to make a pin an output, while other peripherals override the TRIS bit to make a pin an input. Since the TRIS bit override is in effect while the peripheral is enabled, read-modify write instructions (BSF, BCF, and XORWF) with TRISC as the destination, should be avoided. The user should refer to the corresponding peripheral section for the correct TRIS bit settings. PORT E has only three pins (RE0/RD/AN5, RE1/WR/AN6 and RE2/CS/AN7) which are individually configurable as inputs or outputs. These pins controllable by using its corresponding data direction register “TRIS E”.

These pins also have Schmitt Trigger input buffers. The PORT E pins become the I/O control inputs for the microprocessor PORT when bit PSPMODE is set. In this mode, the user must make certain that the TRIS E bits are set and that the pins are configured as digital inputs. Also, ensure that ADCON1 is configured for digital I/O. In this mode, the input buffers are TTL. Download vandisk usb driver.
