How many ports are there for PIC and ARM?
I/O Ports PIC16 series consists of five ports, such as Port A, Port B, Port C, Port D, and Port E. Port A: It is a 16-bit port, which can be used as an input or output port based on the status of the TRISA register. Port B: It is an 8-bit port, which can be used as both an input and output port.
What is PROFIBUS connector?
The PROFIBUS DB9 connector is used in most IP 20 environments and is the best solution for high transmission speeds. The connector is perfect for establishing a connection between cables and to create the ideal branch. The majority of connectors have coils to suppress noise and reflections.
Which is better PIC or ARM?
It can be programmed to carry out a vast range of tasks. PIC micro-controllers are available in 8-bit, 16-bit and 32-bit. It is based on RISC Instruction Set Architecture and Havard memory architecture….Difference between PIC and ARM :
| S.No. | PIC | ARM |
|---|---|---|
| 09. | It has a very good community support. | It has a vast community support. |
What is PIC full form?
The acronym PIC stands for “peripheral interface controller,” although that term is rarely used nowadays.
What is PROFIBUS DP cable?
Profibus cables are automation cabling for industrial fieldbus fast-connect-type systems, particularly developed for process applications. They offer excellent electrical transmission performance for their respective Decentralised Peripherals (DP) and Process Automation (PA) applications.
What is DP protocol?
PROFIBUS DP stands for Decentralized Periphery. The name refers to the I/O connections, which use completely decentralized high-speed serial communication to connect to a central controller.
How do I check my PROFIBUS connection?
Probably the best way to physically check a Profibus cable is to use the Siemens BT200 tester , which will test for Cable A/B breaks , cable A/B being swopped , cable shield breaks and incorrect terminations etc.
What is PROFIBUS module?
PROFIBUS DP (Decentralized Peripherals) is a network that is made up of two types of devices connected to the bus: master devices and slave devices. It is a bidirectional network, meaning that one device, a master, sends a request to a slave, and the slave responds to that request.
How many pins are there in pic16f877a microcontroller?
PIN CONFIGURATION AND DESCRIPTION Of PIC16F877A microcontroller As it has been mentioned before, there are 40 pins of this microcontroller IC. It consists of two 8 bit and one 16 bit timer. Capture and compare modules, serial ports, parallel ports and five input/output ports are also present in it.
Which pin is positive on a PROFIBUS cable?
Pin 3 and pin 8 are used for the data transmission. This is where you will connect the green and the red wire. The green wire is usually the positive or channel A. So, when you are connecting the Profibus cable you should be connecting the green wire to pin 3.
What is the current limit for pic16f877a GPIO pins?
Therefore, the current limit for each GPIO pin of PIC16F877A is 10 mili ampere. As it has been mentioned before, there are 40 pins of this microcontroller IC. It consists of two 8 bit and one 16 bit timer.
What is the LVP bit on a PIC 16f877a?
By default from the factory the LVP bit is set to 1. If Low-Voltage Programming mode is not used, the LVP bit can be programmed to a ‘0’ PIC 16F877A has an internal EEPROM data. Two bits, CPD and WRTD, protect the entire data EEPROM.
