The MSP430 Launchpad will be used in the First Year Introduction the Electronic Engineering and in the second integrated engineering project. Introduction The Getting Started with the MSP430 LaunchPad Workshop is free, on-line, in-depth introduction into MSP430 basics including: An. The TRIS registers are located in the bank 1. The two registers that we are interested in are the direction register (P1DIR), and the output register (P1OUT). In my project, I use a few basic macros for GPIO. A key to getting good power performance out of an MSP430 application is good use of timers and hardware interrupts. These pins can be controlled through the MSP430's I2C command set. pt Registers (1/6) Independent of the I/O port type (non-interruptible or interruptible), the operation of the ports is configured by user software, as defined by the following registers: Direction Registers (PxDIR): • Read/write 8-bit registers; • Select the direction of the corresponding I/O pin,. Additionally register examples for some of the internal peripherals will be demonstrated and explained. We will show it based on the STM32F4-Discovery board, however controlling the timers of other STM32 devices is very similar. 0 I/O Port 1 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 GPIO = General Purpose Bit Input/Output 8-bit I/O ports 1 to 12 ports, depending on family and pin-count Each pin is individually controllable Input pins can generate interrupts Controlled by memory- mapped registers: IN OUT DIR REN. In this MSP430 programming tutorial part 1 some of basic C operators used for programming the MSP430 will be looked at. Texas Instruments MSP432 Driver Library What DriverLib is The Texas Instruments MSP432 Driver Library (DriverLib) is a set of fully functional APIs used to configure, control, and manipulate the hardware peripherals of the MSP432 platform. System clocks. When the bit for a given pin is cleared in both of these registers, as they are on reset, the pin is configured as a digital I/O (also called a general purpose input/output, or GPIO). Finally the code that resets the output value was delete to avoid losing the pullup/down resistor configuration. 3V for Raspberry-Pi and 5V for Arduino Most important pins includes UART, SPI, IIC, GPIOs are mapped onto the board, only pins A0-A3 is not in used. The errors are showing undefined on GPIO_IOCLR and the other similar stuff shown above, I am working with an LPC-2148 Proto Board. of registers. In the last post I explained what is PWM and how to use it to control a servo motor. A good rule of thumb is to enable the interrupt of the last memory channel that is to be sampled from.
