Thanks, did not know srand() existed (even for avr so it seems). So, in essence I reinvented the wheel. Thanks for the embtextf link, will have a look into that.

In an attempt to port one of my projects from AVR to the MSP430G2553 and failing horribly because the printf() function in CCS does not fit into the 512 bytes RAM, I did manage to port a single function. The function, READrnd(), reads some pre generated random numbers from flash memory. I use them to give my projects some (predefined) randomness. For example, the project I want to port uses the predefined random numbers to "randomly" turn on and off 8 relays. I am going to use it for some night/day simulation in houses on a model railroad track. Anyway, with the MSP430 version of the onlin

Hi there! I just registered on this forum to learn more about the msp430 microcontroller. I have started working with 8 bit avr micro controllers before the turn of the century starting with the at90s1200 (the very first, no RAM). Hope I am welcome here. Yesterday I found a post in the beginners forum pointing out that you need both the data sheet and the family guide to understand how to program a msp430. Helped me a lot. With 8 bit avr's you get them in one datasheet. On my left is a msp430 launchpad wildly binking its leds at me Met vriendelijke groet, Marc The Netherl
