Hello, I am using BSL to program a MSP4301F1612. The TCK pin of the programmed processor is also connected to the CS pin of an SPI driven SD-card. From my...
Cool. In that picture what does the current source in parallel with the diode (at the bottom left) represent? Regards Michael Dalton ... [Non-text portions of...
Hi Jim, Thank you for the link and the fast answer. Your example looks great, and I have been able to implement printf, putc, and puts on uartA1 on my board....

Thx. The current source is your MSP430-output with a resistor in series. The diode at the current source does _not_ have any function. M....
Then try something like the MICREL MIC5011 driver. For low or High side MOSFET driver. A $4 IC from digikey. http://www.micrel.com/_PDF/mic5011.pdf See also,...
Scott, take a look at the interrupt-driven input of my posting to the TI e2e site. Using that technique, you can collect the input string, saving it in an...
Oops! I did a no-no, I searched for "SDI-12", got a link to a wiki, and posted it without trying the link. Turns out there is not, and apparently, never was, a...
I started a new thread because I wasn't entirely sure whether you were using printf for debugging or something else. ;-) I just took a quick look at the...
Peter, I appreciate your input, and have, for various reasons, debated whether to respond to your comments. I don't really need to explain my reasons why, but...
You state that you require "accuracy to the 6th decimal place" and yet you then say that this is a reason to revert to C's internal floating point routines....
It's worse than that. 1.654321 That is 7 significant figures. float can't deliver that. You'd need 64-bit doubles to read and print correctly without loss....
Al and Paul, you are both correct. Perhaps I was not as precise as I should have been in my response. I sent that out at 2:30 AM, after working all day, and ...
... Certainly valid reasons there, and no need to argue. Although I am a hobbyist and the cost of additional speed/ram/rom/power is a complete non-issue, I...
@Matthias ... Ohhh ok :) @Ed ... That's spot on, ordering one now, will update on how it goes (hopefully well) Regards Michael Dalton ... [Non-text portions of...

Hey Matthias, When you drive the PMOS in the circuit are you driving the gate 'ON' with logic 0 (GND) or does this circuit invert the logic signal? To ask in...

I have a problem abiding to 2 MISRA rules (Yes it is a requirement that is imposed on me, but can I justify not complying to these 2 rules, if so how?). #109 &...
... No, don't think so. ... #109. This is to avoid endian, packing, and other issues. I find that unions are rarely, if ever, needed. There is absolutely no...
Thanks Paul for the reply, Case #111: I have a bitfield of 19 bits, among other bit fields inside a struct, so I use a long, instead of int (in this case int...
Hi, ... This is where standards and extensions collide. However, do you really need to save 32-19 = 13 bits? You really, really can't afford to break out...
... Yerrch. You can do that in portable C--why use a bitfield? That's 100% non-portable. Does MISRA allow this? I don't think so. Reading Rule 3.5 and...
Basically, it's a struct. Each field has a name, and the user really doesn;'t need to know its location within the long word, nor its size, just its name. ...
... That's fine. But why not answer the question, which was "Why do you not do this in a portable manner rather than try to use something that is outlawed and...
