MSP430 --> AD421 DAC current loop problem
I hope someone with some experience with the AD421 can point us forward with a problem we have. We've got an MSP430F149 driving an AD421 16 bit DAC as a 4/20mA current loop driver. The AD421 is isolated using H11L1M optocouplers, the F149 is battery powered and completely isolated from the AD421, we have used the... 18 Sep 2005 18:25

S1D13700 Grayscale configuration
Hi all, I'm using a S1D13700 with my 320x240 display with 1bpp without problems for weeks. Now, i'd like to increase the color depth to 2bpp (maximum color depth @ 320x240). I experience some difficulties since grayscale mode is not develloped in the datasheet : - [FX] should be set to 0b0111 - [C/R] is (... 11 Aug 2005 11:07

Couldnt read MT8888
Hi.. I'm trying to build my own PSTN-based home controller. Yes, I know that many would suggest to build IP-based one. The problem is subscribing internet here is far more expensive than subscribing PSTN-line. Sucks.. Anyway, I use AVR Mega8535 with MT8888 so I can control my house and get its status (throu... 26 Jul 2005 13:21

Chipcon & other RF transcievers?
Hi everyone. Has anyone here used Chipcon transciever parts? I'm thinking about using the CC2500 or maybe the CC110 for a project and wanted to find out the pro/cons for these devices. Also, is anyone aware of a part in this class (embedded RF, SPI or UART interface) that can do 1 Mbps? Finally, how goo... 16 Jul 2005 11:56

MSP430, gcc -> IAR
I'm an experienced C/C++ programmer, but very new to Embedded programming. I've bought the TI Flash developers kits that include the IAR compiler. I have some existing msp430gcc code, but there are some differences - particularly in how interrupts are declared. The issues I need to resolve: 1) some of my in... 3 Jul 2005 16:19
