Hi Leo
This forrum is basically closed.
If you lucky, somebody from flowcode team will see your message.
If you use FC10, go to a new forum.

Hi

.temp[.count]=GLCD::ReadASCIILUT(.pos_str,.count)
----------------------------------------------------------------
During my study of oled SSD1306 I crossed the above code inside the Print macro.
Can somebody attaches/exlain this macro?
Thanks

Hi
A very interesting project, chipfryer27.
Some people used 7600:

Hi George
Please search this forum:
convert two Int to one Float

Hi
Use search window. Enter Nokia 5110.
Should be some discussions on this forum.

Understood.
Thank you for your help.

The Atmega 328 ROM size is 1kB.
As LUT table uses the ROM:
I can store only 100 values with 10 byte in one value.
-----------------------
As I want to store 100 integers, the storage size should be 16x100=1600 bytes (at least).
Is it a problem?

Hi
Can you add your chart, please.

Hi I have tried to include the lut component (removed the C-icon (lut)). I have the error: lut undeclared... or other errors. ------------ If I remove the lut as an integer array or as a FC8 lut component, and use (for example) ten values, instead of 100 lut values inside the interrupt 0, 247, 470, ...

Hi
The lut component is not used (should not be included).
The Interrupt uses C to create a direct access to Timer1 .
I will check today the program (without the lut component).
I am not sure, but (probably) the included (but not used) lut component can create some problems.

Hi chipfryer

If Lut table inside the interrupt,
- the interrupt macro works, but
- the main macro does not work.

If Lut table outside the interrupt,
- the interrupt macro does not work, but,
- the main macro works.

Hi
One more question.
I understand, that locals in interrupt macro is not saved.
I need to use static or globals.
What is the best?

Hi
lut table works OK inside the interrupt macro, however the main macro is not. Test B5 does not flash.
If I use the lut table outside of interrupt (before the main macro) B5 flash OK, but the interrupt does not work.
Any help, please?

Hi
Can you please share the results?
What was the problem?

Hi
I used the FC8.
Works OK, only one problem with 'interlaced' function.
Didn't work in 'yes' version.
No problems with 100kHz or 400kHz

Hi
Can you please give more information?
Did you try a second, third OLED?
Do they all work the same?
Does Nano work OK with 1 second B5 flash?

Hi Enrique There is a reason, why MFRC522 has only a few milliwatts in the output. It was discussed here: https://www.edaboard.com/threads/rfid-13-56mhz-power-amp-design.131000/ You can create more powerfull transmitter and more sensitive reciever, however some cost is involved and some legal issues...

Hi Martin The ATmega328 Timer1 can be configured (if directly accessed) into the Phase Correct Pulse Width Modulator (PWM) mode. So far I have problems with the custom code for Timer1 TCCR1A = 0b10110000; /* 10xxxxxx Clear OC1A/OC1B on compare match when up-counting. Set OC1A/OC1B on compare match w...

I am not sure where should be the interrupt title in this code...
ISR(TIMER1_CAPT_vect) // input capture vector
{
FCM_%n(); // Call Flowcode Macro
}

Doesn't look like interrupt calls the Timer1 macro

Have tried the next code, but due to my C-code errors, it does not work

Hi In the article - Arduino Uno SPWM Inverter, https://yopiediy.xyz/ https://yopiediy.xyz/arduino-uno-inverter-12v-to-220v-pure-sine-wave/ Author used Timer1 to create the SPWM by using one Lut (table). The Time1 code: TCCR1A = 0b10110000; /* 0b10xxxxxx Clear OC1A/OC1B on compare match when up-count...
