Latest MAX7219 component for 7digit display

The last time I've played with the MAX7219 was in 2015 according to my Flowcode files. Now I want to use it with a board that contains 8 7-digit displays. ( https://www.aliexpress.com/item/1005003217251335.html?spm=a2g0o.productlist.0.0.38115801jOwdIE&algo_pvid=d09a317b-22ef-4301-b69e-3b0844f5654c&a...

Oscillator question (LP-mode)

In the datasheet for the 16F1827 ( http://ww1.microchip.com/downloads/en/devicedoc/41391d.pdf ) as from page 299, I see tables with different BAUD rates with different Xtal's. "BAUD RATES FOR ASYNCHRONOUS MODES" I want to use a PIC that consumes as less power as possible, and then I see the 32khz XT...

Re: Who uses cheap 433Mhz modules?

First range test today with the HC12. Default settings and sender was lying on my desk on my attic. For me this was a great success. Line of sight I got errorless reception at approximately 150m. This is more then I hoped for in these conditions and with the default settings + the cheap coil antenna...

[Solved] Arduino Nano UART problems

It's nice to start a topic with "solved" in the title . In Belgium we have a saying that, translated, must sound something like: " A donkey doesn't hit the same stone twice", but I must be dumber then a donkey :-) In some projects I've used the UART of a Arduino Nano (Chinese version with a CH340 ch...

Re: Putting a PIC in sleepmode for 1 minute

Hey guys, After playing a few hours with the settings for the 18F4550 on a Matrix EB board, I finally got it to flash a few LED's :-( The problem with the EB006 seems to be the switches for the XTAL and others. So after a few hours I got it to flash leds and show a text on a display. My goal was to ...

Re: Putting a PIC in sleepmode for 1 minute

Hey thank you chipfryer:

I've edited the testfile like this:
SleepPIC.fcfx
(8.63 KiB) Downloaded 207 times
The WDT is set to 1/32768 postscaler in the settings, so it will start the loop again after 32768 cycles (I think 1 cycle is 4ms).
So this should work?

Re: Putting a PIC in sleepmode for 1 minute

Hi You can certainly reduce your power to the point you can barely measure consumption unless you have some serious test kit <s> It seems like you may be sending out values every minute or so. Without question the RF when transmitting will be you biggest draw so try and minimise this. Depending on ...

Re: Putting a PIC in sleepmode for 1 minute

Hi Getting best battery life is indeed a "black art" and in my opinion you need to consider this from the onset. Personally I think you need to design around such rather than add it in later. Microchip have many guides for enabling "Sleep" and "Deep Sleep" function. If you do a search for "microchi...

Re: Putting a PIC in sleepmode for 1 minute

By mistake I don't have the proposed MCU here right now ( PIC18F14K50), but another NanoWatt MCU is lying here next to me: the 18F4550. For testing purposes it seems that this old PIC will work too?

Putting a PIC in sleepmode for 1 minute

I'm looking to make a project where a PIC is used, powered by a battery. This project needs only to work a few seconds each minute. The rest of the time it should use as little power as possible. I was looking for the PIC18F14K50, as a NanoPower device that can be but into sleep mode. (https://ww1.m...

I had great success using these and they have built in detection to ensure that the data is valid before presenting it on the receiver. https://www.rfsolutions.co.uk/radio-modules-c10/alpha-c80 Unfortunatley the smaller modules at least seem to be end of life, I think in part because things like th...

Add "Solved" on this part of the forum :-)

I was reading this part of the forum, and it would be nice to see which suggestions are implemented.

Is it possible to add [Solved] to the title if the suggestion is added to Flowcode?
Would be a great feature to this forum.

Does anyone agree?

Does anyone use Flowcode with cheap 433Mhz modules like these ones: https://www.tinytronics.nl/shop/nl/communicatie/rf/433mhz-rf-transmitter-en-receiver-link-kit It seems like the connection is like a RS232 signal without real timing (just data).
