I have some rights now. I'll check for spam daily when I'm able to.

Of course in hindsight I am probably stepping on some copyright rules by having this printed, but I don't think anyone's going to complain about that... it's a developer's manual and I am using it for developing with TI parts after all.

I decided "for the hell of it" to print out the MSP430 chip family User's Guide, all 676 pages of it (slau445). Total cost was ~$70 altogether including the $10 binder from Staples. I used bestvaluecopy.com for the printing - printed in B&W, with a thicker color cover sheet, 3-hole drilled, shrink-wrapped, and put it in my own binder. Reading the more esoteric parts of the book - like the PMM, SVS and CS systems - is actually much nicer in print I found. Just more comfortable to sit down at the table and *look* at the diagrams and text and hold my left hand under the page with the

Can some of us get moderator rights? Take a load off your back I'm getting back into the hobby as of recent so I can watch it for now..

I may have posted about this a long time ago, but I had written a library to utilize the Nokia 1202 cellphone parts LCDs - there are a couple BoosterPacks we made years ago using this and I have at least 1 working board in my bin of parts. https://github.com/spirilis/msp1202 The library includes "msp430_spi.c", which provides an implementation of SPI for several chips including some of the FRAM chips (FR5969 and FR2433 iirc). As the Nokia 1202 LCD does not break out the D/C line, it requires 9-bit SPI, and the "spi_transfer9()" function is defined for those chips (for all the eUSCI_

Kicking off my MSP430FR2433 hobby effort I looked into the RTC peripheral, which amounts to a really simple stupid counter, the likes of which I often used WDT for back in the day. It just counts up to RTCMOD and then fires the ISR. So without the fancy date tracking that RTC_B did on the Wolverine chips, I had to up the ante a bit and write myself a library to convert "epoch" seconds format (# of seconds since Jan 1 1970 midnight UTC) into a "struct tm" year/month/day/hour/minute/second/etc. structure and vice versa. I looked around for other implementations and found some inspirat

Finally getting back into it. No workbench yet, but I start a 4-week sabbatical after next week, so one task on my plate is to revamp the basement with new shelving + bigger work from home office & workbench. In the meantime, I noticed the older TI SimpleLink hardware seems to be deprecated - the latest SimpleLink SDKs no longer support them & it halts with PG1.x hardware (requires PG2.0+). So I threw all those launchpads away. I guess I'm getting old or maybe wise enough to realize when something isn't worth the effort... So my focus now is the MSP430FR2433 - the Value-Li

Cool article! Random thought just happened upon me, I wonder if there's a registry of all semiconductor fabs in the world?
-
Ha that is cool! I guess one side project I need to pick up "at some point" (code phrase for "sometime next century if I'm still alive") is DIY electrification of our bicycles. My son especially needs some motorized motivation... we moved to an area that's quite hilly!

AI and edge? That sounds fancy... what kind of edge hardware?

HI folks- Old time forum member here, but been away from the microcontroller hobby for a few years... sold my old house, moved to a rental for a year, now finally in a new "permanent" house for hopefully a long time. The basement is an utter mess but I have all my electronics parts, soldering equipment, an entire bin dedicated to TI launchpads, stored in my crawlspace (w/ dehumidifier) for when I clean up this mess of a basement & set up my new workbench. So what's everyone working on these days?

Compiling CMSIS DSPLIB to MSP432 (and other cortex M4 from TI)
spirilis replied to agaelema's topic in Code vault
Hi- quick question, do you have any software you like for designing filters? (e.g. FIR or IIR coefficients) I may be dabbling into MSP432 DSP work soon... -
Mind you the 20km (actually 30km now?) was tested at the top of two buildings in Norway with clear line-of-sight between them.... but 0.3km still sounds bad to me. Wish I had some time to keep playing with these, as I want to follow up on a lot of this stuff.

I haven't messed with energia in a while but I am pretty sure SoftwareSerial doesn't work on that chip... it was meant for the really small MSP430G2452 and similar which didn't have a hardware UART. Arduino handles softwareserial better. Maybe someone else has a better softwareserial implementation around here, I don't know though.
-
Bringing back threads from the dead! Can you provide more context here? The GPS shouldn't use the same UART as another device (camera? what kind?) but otherwise yeah, Serial1 should work...
