I feel some serious tool-envy

I feel some serious tool-envy

Got my enclosures today. That means I now have all the hardware parts for this batch.
 
I've been playing around with Fusion 360 instead of Rhino, mainly due to the integrated CAM processor. Also it has easy to use rendering stuff out of the box too.
 
This is the reason I love companies that provide 3d CAD files. I can define some simple stroke text, and Fusion 360 will project it over the 3d curvature of the part.

 
My CNC setup is in dis-array. The setup is sub optimal.

 
But I think the results speak for themselves.

 
I want to experiment with filling the engravings with a paint to make them stand out.

Went through and soldered up a batch of new PCBs


 
Paneling PCBs made this process much fast.
I'm still using my manual PnP which isn't very fast or accurate, especially after a few coffees.

Your program doesn't make any sense as is. You have counter variables that are never counted up or down. I think you copied a program that you don't understand. Someone from a forum rewriting it for you won't help you achieve your goal.
 
My suggestion is to either start from scratch and build the program step by step, or at least try to understand how the original is supposed to work before you change it:
https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/529768
 
I see that Dennis tried to be really helpful on E2E but ultimately lost patience. Starting from scratch with Energia or a beginners tutorial might be your best bet.

Then try to fix the warnings. The if statement I mentioned above probably does not what you expect. It will always set output_control to 1.

It might help if you try to explain in a bit more detail what your code is supposed to do. You won't get many answers if you expect people to parse 100+ lines of code.
 
There are a few errors in the if/else in the ISRs. The compiler will probably tell you about these if you look at the warnings.
 
E.g. :
 
if ( output_control = 1 ) .. i
 
and:
 
else ( ouput_control == 0 )

Only when consumed socially. Back in the day (.com bubble) my theory was, that ideas from the Friday night pub crawl which you still remembered on Monday morning must have merit.

During development / testing original (TI USB) BSL was untouched. My BSL was placed in main flash, started by RESET vector and copied to RAM. Main flash was not used anymore and it was ready for user program. After downloading user program by RAM BSL, and device reset, user program was started.

Only when consumed socially. Back in the day (.com bubble) my theory was, that ideas from the Friday night pub crawl which you still remembered on Monday morning must have merit.

When I was working on my BSL, all testing (with logs) is done by using main flash, without touching BSL flash area. (In any case) BSL was copied to RAM and executed from there. At the and it was relocated to BSL area, and flashed, after I was 100 % sure that everything is OK with generated (2 KByte) TI txt file.

Have you tried a lower SPI speed, as the TM4C123 runs at 80 MHz?
 
To do so, change SPI_CLOCK_DIV32 for SPI_CLOCK_DIV64 or SPI_CLOCK_DIV128.

Do you set the chip select (CS or SS) pin?

In more detail, now that I looked at the MSP430G2553 datasheet:
 
To use I2C, the TI library will set bit 5 and 6 in P1SEL and P1SEL2 to connect these pins with the USCB0 peripheral. See table 19.
 
Looking at the schematic on the previous page, P1SEL and P1SEL2 are connected through an OR gate to the active low enable pin of the interrupt logic. I.e. if one of the two is high, there will be no interrupts.

 
You could manually clear bit 6 in P1SEL and P1SEL2 when you are waiting for the INT signal, and set them again before start using I2C.

@@fatihinanc
Out of the millions of chips out there, you guessed correctly!
Working on the same? Did you figure it out...
 
@@chicken,
i2c just uses P1.6 and P1.7 I believe?
void i2c_init(unsigned char addr, unsigned char prescale){     //P1.6 SCL / P1.7 SDA     P1SEL  |= BIT6 | BIT7;     P1SEL2 |= BIT6 | BIT7;         //... } Isn't P1.5 just used for SPI?
I will try your suggestion. Think the whole thing stranded when I do that.
 
As a general note I'm trying to see the Interrupt on my little DSO202 oscilloscope, but not really getting around with that thing.
Maybe the problem is that the pin is pulled high with 1.2kOhm resistor?
 
Will return with more findings, thanks for thinking with me :-)
 
EDIT:
 
I got it working, due to your hints/ideas.
For future reference this is quite simply it...
void main(void){ //setup... for(;{        //issue i2c command...         //P1.6 SCL disable         P1SEL  &= ~BIT6;         P1SEL2 &= ~BIT6;         P1IE   |=  BIT6;                            // interrupt         P1IES  |=  BIT6;                            // falling edge (default)         P1IFG  &= ~BIT6;                            // flag clear         __bis_SR_register(LPM4_bits);      // sleep         //-----------------------------------------------------------/         P1IE   &= ~BIT6;                            // !interrupt         //P1.6 SCL re-enable         P1SEL  |= BIT6;         P1SEL2 |= BIT6;                 //read i2c data } } #pragma vector=PORT1_VECTOR __interrupt void ISR_P1(void){     if(P1IFG & BIT6){         P1IFG &= ~BIT6;                        // clear flag         __bic_SR_register_on_exit(LPM4_bits);  // clear LPM bits, returns to main after last LPMx     } } Thanks again!
 
Now to make sense of the data

@@abecedarian No worries, the MSP430 USB peripherals and libraries handle that nicely. You can query the USB status (connected, suspended, enumerating etc.).
 
The main request is, that TI offers more MSP430/432's with USB peripheral. I think right now USB is only available in the MSP430F55xx family. It seems that with all the IOT hype, some manufacturers assume that USB is becoming obsolete.

USB and Low Power are indeed a very much desired set of coupled features. For example, making a portable device that runs from a small battery or solar cell that you want to configure or extract logged data from at the end of the day or something. Perhaps the battery recharges via a USB connection as well. So, having USB to communicate to the device when charging is a definite feature worth having. It can be low power when not connected to USB.

I just took a look at the Energia implementation of Tone and it does not use PWM but just a timer and toggling the pin manually in the interrupt routine.
https://github.com/energia/Energia/blob/master/hardware/msp430/cores/msp430/Tone.cpp
 
This should make implementing toneAC a lot simpler.
 
ISR code:
*tone_out[n] ^= tone_bit[n]; \   if ( tone_periods[n] == 0 ) stopTimer(n);\   else if ( tone_periods[n] > 0) tone_periods[n]--; \ ccr += tone_interval[n]; \ The tone_out array holds the port and tone_bit the pin to be toggled for a given tone n. All you will need to do is add tone_out_neg and tone_bit_neg arrays and initialize and toggle them together with the existing code for tone_out and tone_bit.

Mhhh, there are some interesting things starting to show in the Energia GitHub repositories:

A wise man once told me, to stop worrying about things that I can't change. There will always be people copy&pasting or even claiming other's ideas as their own. No license will prevent that, and IMO it should not prevent you from publishing if free education or help to others is your intention.
