Re: Help!ez430rf2500-seh solar energy tool-can not use UART
Here is my code:
linkTo()
{
...
P3SEL = 0x3f; // If i put this one here, transmission will fail
BCSCTL1 = CALBC1_1MHZ; // Set DCO = 1MHz
DCOCTL = CALDCO_1MHZ;
UCA0CTL1 |= UCSSEL_2; // SMCLK
UCA0BR0 = 0x68; // 1MHz 9600...
I hav the ez430-rf2500-seh solar energy harvesting tool. I decided to make some modification based on the Demo code.
I wanna choose P3.5 (UART) as a receive pin.
I follow the sample codes to write a simple interrupt.
I disable the previous P3.5 function (connect to solar panel inner battery...
I know that for MSP430fg439, there is a way that u can transmit or receive data without using interrupt enable. ME can replace IE.
I try to find the same way in MSP430F2274, but i cant.
Is there any method to be in the UART mode in MSP430F2274 without interrupt? Where can i find this kind of...
I followed the sample code from the TI.
The ez430-rf2500 target board receives an external signal from a heart rate board(MSP430fg439). I first pass the value of UCA0RXBUF to UCA0TXBUF for testing. I observe the signal from P3.4(Tx) pin by using oscilloscope. It is square wave and it is correct...
There is a table about commonly used baud rate on user guide.
However the frequency i use is 2.097152Mhz = 1.048576Mhz * 2 which is not in the table...
I want the baud rate to be 9600. So i set:
UBR00 = 218; // 109 *2
UBR01=0;
But i dunt knwo how to set the modulation
UMCTL0=??
Any...
Re: Help! Heart rate board (MSP430fg439) can not be powered
Im trying to preset a value(int) in the program. Then later i can replace the value by heart rate reading. I chose P2.4 to be the output pin.
The board is workable and it is fine with original programming. After modifying the...
Re: Help!Try to input an integer to ez430-rf2500 target boar
aHHHH I FORGOT to post a question..............i was too tired tat day.
when i push the push button, it shows red light instead of green light. I check n find if i erase the port 3 initial setting, the green led would light.
then i...
Re: Help!Try to input an integer to ez430-rf2500 target boar
Tks a lot! I am quite new to this tool. XP
I download some sample code from TI. The whole programming is based on the SHE monitor sensor sample code. I change my code today(I juz write the main parts):
int aNumber
main
{
P1DIR =...
I wanna connect another hardware to this target board. That target board will send an integer to this target board.
I choose P2.0 as input pin.
But when i open putty.exe to check the transmission data, i only see 60.
By right, i should see aNumber=0 when there is no input apply to port...
