Hello, When I toggle a GPIO on my MSP430 processor I have (or at least I think I have :) a clean understanding of what happens. I can relate the frequency of the toggling to the instructions used and the clock speed of the CPU. Nothing strange happens. The MSP430 runs the instructions below: /* Put 0xAA in the r15 register. */ mov.b #-86, r15 /* Write the contents of r15 on p...

Hi all, I?ve read the C code made by Xilinix to program a FPGA using an embedded microcontroller. The application is written to fit the 8051 and I have to port it into a MSP430f1232 to program a Spartan 3. In the application description it says it is easy to port the code into others microcontroller and it is only needed to change few functions in the file ports.c but my GCC refuses to com

Just got the USB version, eZ430-2013 Development tool, but It's not being rocognized by my PCs. Can anyone help? I just emailed TI, and while I wait for reply, thought I'ld ask here. I followed all installation instructions. When I plug it in USB, it's recognized as a MSP-FET430UIF JTAG device, then up pops the Hardware Wizard looking for a driver. I browse to where TI says to, but to no a...

Followup to the message I posted the other week about Nokia 2260 LCDs for my Babylonian clock... the electronics are now working. The clock starts at 10:12:10 and ends at 10:13:08 in this video; you get to see most of the digits. It was slightly tricky to fit the 59 digits (at 32 x 22 pixels) into the 2K MSP430; I wound up making a set of sub-

Hi, I'm trying to clock the CPU (MSP430F1611) to 8,000,000 Hz and I've run into some problems. Making the CPU to actually run at 8MHz was easy enough: DCOCTL = DCO0 + DCO1 + DCO2; /* 0xE0 */ BCSCTL1 = XT2OFF + RSEL0 + RSEL1 + RSEL2; /* 0x87 */ However, the UART1 stopped working. What I've got so far is: void uart1_init( unsigned int ubr ) { /* RS232 */ P3DIR &= ~0...
