So, here we go. Attached is the Transmit FCF. I tried to separate the code related to ATM90E32AS energy meter but proven quite difficult as the LoRa TX-RX packet length is configured to carry out 40 bytes. The time delays within the main Loop are critical and have been calculated by experimenting to...

Looking forward to seeing the code, LoRa is something I've still not managed to dabble with yet. Yes, I know, the same applies to myself. Lot of work, no time :lol: Here is the schematic LoRa_SX1262_TX.jpg LoRa_SX1262_TX.pdf I'm working to modify a bit the FCF, basically to remove some custom varia...

Bantham_Moment_Moment.jpg The two boards are identical, the left is configured as energy monitor and transmitter and the right as the receiver. The host micro is a PIC16F18877 with dual SPI bus. One bus is allocated to the polyphase energy monitor ATM90E32AS of Microchip, and the second to the LAMB...

Tip: this will save you from the need of using several switches to set the actual date and time. Only a user switch, few settings, and 3 times flash of micro are necessary to initialize the RTC calendar and clock. In my hardware, the switch is attached to port PB.11, for that reason the Port interru...

Hi :D As no Stopwatch function is provided by the current FC component for the STM32, here is a complete FCF that initializes the RTC and provides an elementary stopwatch that can count up to 60 minutes. I will use it in my future project "Thermostat for central heating" to calculate the oil consump...

Hi Leigh I have great news! Everything is compiled and works perfectly on my actual hardware :D Here a picture: IMG_20200124_102714.jpg I did a trick within FlowCode to set the time according to the Windows clock. (Don't scare, UK time = GR time - 2 hours :lol:) I soldered and the backup battery and...

Hi Leigh Yeah! It works :D LSE RTC is working and LCD prints and updates the time every second. Simply now I've lost some port interrupts. The only presented are: EXTI0 EXT1 EXT2 EXTI3 EXTI4 EXTI8 EXTI13 If you remember, 2 months ago, I had this problem and you resolved it with the new fcdx file in ...

Hi Leigh
If that could help you, here is a picture that shows what I meant saying: If all "SET" RTC component macros are bypassed just for a test, then the LCD prints normally. Thanks

Hi Leigh Thanks a lot for your help. I appreciate it very much. However, there are 2 issues occurring from the fact that on my hardware I use an external XTAL of 32.768KHz: 1) If the LSE is selected the compiler returns the following error: RTC_STM.o: In function `FC_CAL_RTC_Init_1': RTC_STM.c:(.tex...

Hi... again :D Is there any help or tutorial of how I could set up the RTC of STM32F303RE within FC? Using the STM32CubeMX is quite easy as I can also set the current day of the week, month, year. Unfortunately, I haven't the possibility to also include in CubeIDE the FC generated code of the 4X20 L...

Thanks!
Should I replace the: with And then to add into the same code window the line: ?

Thanks

Thanks,

I will try it in a couple of hours and will let you know (lunchtime in Greece )
I have to modify my variables.

Hi Leigh

Yes, FC compiles successfully with this equation. No errors. Thanks.

It remains, how I could read back the 32-bit data register "ADC12_CDR".
E.g. ?

Thanks again

Hi everyone and Happy New Year. I try to enable the Dual ADC mode on STM32F303 without success. In dual mode, the ADC1 and ADC2 work simultaneously, and the ADC2 is the slave of ADC1. The result of conversion is stored into the "ADC12_CDR" 32-bit register, of which the higher word "RDATA_SLV" contai...

For your interest, FC supports up to 1 ADC converter per device till now. If you are going to include more ADCs, like in the case of STM32F3 which offers 4 independent ADCs, here is a working and tested FCF created by LieghM for our own use: https://www.matrixtsl.com/mmforums/viewtopic.php?f=63&t=21...

Hi Leigh Sorry for the delayed reply. I can confirm that the macros are working flawlessly on my actual hardware with the STM32F303RE. You have configured the SMP register at 61.5 ADC clock cycles. I checked the CAL_ADC file and that is related to the acquisition time of 40us. else if (T_Charge > 40...

I'm planning to add multi-adc support for the next major Flowcode release. Also currently investigating DMA support for various peripherals including adc. Hi Ben, I really understand the case that it would be an enormous upgrade of FC. I also was based on the... DMA of micro, as all other tasks exc...

Hi Leigh I really need the second ADC. In my prototype PCB there are 4 ADC inputs, connected to STM32F303RE as follows: 1) Pilot1 IN = ADC1_IN1 (PA.0) 2) Pilot2 IN = ADC2_IN5 (PC.4) 3) Proximity1 IN = ADC3_IN1 (PB.1) 4) Proximity2 IN = ADC4_IN3 (PB.12) Here a picture, it is a dual EVSE + Energy Moni...

You are right!

Thanks a lot for the advice.

Any luck with the other 3 ADCs of STM32F303?

Thanks again

Hi Leigh, It helps a lot. Now I try the ADC conversion to be based on a timer interrupt as you told me. So when Timer 7 overflows, it calls the macro CP3 of which the first command is the "ADC_CAL Enable". Capture-1.jpg I try various rollover values of timer 7, as well as various configurations of A...

Hi Stefan

My target is an STM32F3

Thanks

Hi Stefan Thanks for the reply. Do you mean that I should write 128 in the Conv_Speed box? I.e. if I write 255 I will get a 24000000/255=94117.6KHz conversion speed? BTW I try to catch the peak voltage of a 1KHz square pulse, but with a variable duty cycle of 5 to 90%. That means that the lower spee...

Hi everyone
I like to use the CAL_ADC component from the TOOLS menu.
However, I can't understand what value I should give to the Conv_Speed byte.
You could see that in the properties panel I've selected as Conv_Speed = PCLK/4 (24MHz/4 = 6MHz).
Should I give the value 4?

Thanks

Hi Each of the four ADC of STM32F3 generates an interrupt after the end of conversion. Taking as an example the Single Conversion Mode: 1) Inside the regular sequence, after each conversion is complete: • The EOC (end of regular conversion) flag is set • An interrupt is generated if the EOCIE bit is...
