SPI between MSP430/432 and MCP3911
MSP432 posted a topic in Energia - MSPHi, I am trying to read ADC channel values from MCP3911 using MSP launchpad using SPI protocol. When i used Arduino Mega the protocol is working fine. But when i use any TI devices i am having a problem, it always gives me all 0'S or 1's. I am using energia for MSP devices. Any i have chosen the appropriate pins as defined in the enegia pin layout. msp430----- static const uint8_t SS = 8; /* P2.7 */ static const uint8_t SCK = 7; /* P3.2 */ static const uint8_t MOSI = 15; /* P3.0 */ static const uint8_t MISO = 14; /* P3.1 */ Can someone help me troubleshoot where i am goin
MSP430 project for motor control using multiple ISR
Marija posted a topic in Energia - MSPHi all, I'm relatively new to microcontroller programming and I'm having a few problems with a current project that I would appreciate help with. I'm using MSP430G2553 and Energia to control the speed of two vibromotors. To this I use three pushbuttons, one to change from one motor to another and two more(up and down) to increase/decrease the speed. I have 3 interrupts to do all this and I copied the code below. The program works mostly but sometimes it acts randomly, for example, increasing the speed when I press the decrease button, or not responding at all. My questions are these, they
