  1. Well small might have been wrong in this context (10.4 cm), it has 800x480 Pixel, so at 23 Mhz you would get around 60 fps. Anyway i just realised that i cant do simple addition, i only need 32 pins.
  2. Hi i want to use the stellaris launchpad to drive a small LCD module. Unfortunately this LCD uses 3 x 8 Pins alone for the Pixel Date plus 8 more for control. Now on the Launchpad there are only 35 Pins available, the Datasheet mentions up to 43 Pins. I am aware of the "up to", still is there a way to squeeze some more out (maybe directly contaction pins on the board etc), some of the controll pins might be muxed via a shift register but i need atleast 4 more for the clocks. Also regarding clocks, i read this http://forum.stellarisiti.com/topic/395-how-fast-is-the-io/ topic, now it says one c
  3. the tracking number is ti internal, i asked the customer service and they updated me with the real tracking number when it was available, awsome; anyway i got mine today and it also didnt have jumpers and i sadly i didnt have any spares so i just twisted some wire in it to get it up and running
  4. ok this post was misplaced anyway, the solution is using the timera1 instead of timera0 to have the outputs ta1.1 and ta1.2 correspondign with ccr1 and ccr2: note: in this example i am modulating 2 different pwm singals with a shifte sine, (no sine table included here to save space) void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer //unsigned long counter=0; P1DIR = BIT6; P2DIR = BIT1+BIT4; // P1.6 output (green LED) P2SEL = BIT1+BIT4; P1OUT = 0; P2OUT = 0; // LED off //TIMER A sett
  5. hi this might be stupid question but i have been looking for the answers in most referenced tutorials and in the datasheets but i didnt find anything (so if u have the answer and know where in the tutorials/user guides it can be found please also add that to your answer). ok so basically i want to output 2 different pwm signals using timer a. also i got a msp430g2553 because the g2211 i used before has only 2 capture compare registers, so now i got 3. the timer is in up mode and will go into the isp(to update taccr1/2) when taccr0 is reached. for the output i wanted to use the output mod
  6. hi im using the msp430g2211 and tried to modulate a sine wave with pwm therefore i used a precalculated sine table with value pairs for low and high times now i noticed for small values theres a strange behaviour #include int winkel=0; int out=0; int hilf=0; //sine table, test with only 1 pair const int sinus[]={999,1}; */ //float cosinus[]={}; void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer //unsigned long counter=0; P1DIR = 0x40; // P1.6 output (green LED) P1OUT = 0; // LED
