Thanks for your reply Benj, It worked compiled and programmed the esp32 to 100%

OK I have fixed the location, now getting the below message

Target stm32f407zG With flowcode 9

Hi,

Trying to compile a blink for esp32 flowcode 9 keeps saying toolchain not installed.

I have downloaded it and installed 2 times and also rebooted the PC

Hi

WS2812 not compiling, just a very simple code INIT and Set brightnes.


Flowcode1.o: In function `FCD_06621_LED_WS2811__Refresh':

Hi Steve,

At least please consider those who allready owned the chip pack in previous versions to have it @ hobbyist price .

Hi Karthickefy

Everything is very well explained in this video https://youtu.be/c14_sgXaom0

hi medelec35,

That is what I hoped but no the STM32 Chip Pack is only available for PRO and that is
what I am playing with at the moment.

STM32 is why I Bought V7 and the only reason I am interested in V9.

I would pay a bit more for the STM Pack but Pro version everything double the price

Hi ,

I was waiting for v9 to upgrade but STM32 is PRO-only and that's too expensive for me

hello LeighM ,

I can see that this bug is also present on V7.3, I was wondering
is Flowcode 7 still supported for this type of Bugs do we still get bug fixes?

cos I can see that the cumulative update tread in flowcode 7 is quite old
Is there a link we can access to download bug fixes?

Hi, it is just a 1d Array that is storing bytes from an sd card file.
Array = "" dose not work .

I just need to clear it as my problem is when for example first I populate the array with "123456789"
then if I use it again to have it populated with "abc" I get a result of "abc456789"

the only way ...

Hi is there a function to flush / Clear a string Array

I know I can do Array[0] = 0 and so on or a loop that goes true all the array and set
all the elements to 0.

I was hoping something more simple like Array = "" which does not work
also tried a c# icon with Array.Clear(FCV_Array, 0, FCV ...

Hi Alkaline

It Works 100% thanks very much for your help.

Alan

Hi Alkaline

Thanks for your reply I will test this and let you know the outcome shortly

Alan

Hi
I just started playing with STM32 so this is new for me, now I just came across something strange

I made a simple flowcode that initialize the Uart, enables the UART1 RX Interapt, the interapt calls a
macro to receive a string then that string is sent back to me so that I can test the UART is ...

Hi Martin

Thanks for taking the time to look at this and write the macro.

Regarding your question on "how to generalize" I think that we should not try to reinvent the wheel
here cos the bug is in the AVR_CAL_UART.c

Don't get me wrong, I appreciate your work but for now, a simple workaround is ...

Hi Martin

You are right for sure there is no need for high-speed data transfer
will delete the last 3 .

Hi Martin, you are welcome had to dig deep into the datasheet for this :)

It is also good to mention that this will work only on Channel 1 ( uart 0 )
for Channel 2 ( uart 1 ) use registers UBRR1L and UBRR1H instead, values are the same.

below is a simple Macro I am going to use maybe someone ...

Hi This sure is a Bug , but I just found a way around this

Just use a C Code, Tested this and works fine on Atmega 328P.

// Baud Rate 2400:
UBRR0L = 0xA0;
UBRR0H = 0x01;

// Baud Rate 4800:
UBRR0L = 0xCF;
UBRR0H = 0x00;

// Baud Rate 9600:
UBRR0L = 0x67;
UBRR0H = 0x00;

// Baud Rate ...

Hi, I am trying to change the serial baud rate dynamically
but it seems that it does not work maybe I am doing something wrong
been trying all day with no luck.

I bet this bug is also present on V8, I am using Atmega 328P but will be also needing this for Atmega 2560
Would be happy if at least ...

Hi,

Some time ago I made this simple but very powerful Macro thought would be nice to share with the community.
Maybe someone could make a Component out of it I use this almost all the time.

The Macro takes an input string and another 2 search strings, It Searches for a specific word or letter ...

Hi Benj ,

chip is Atmega2560, in the simulation work fine.

Just found a bug in the pow Function

result = pow (x,y)

pow (2,0) = 1 (ok )
pow (2,1) = 2 ( ok )
pow (2,2) = 3 ( ? )
pow (2,3) = 7 ( ? )

if y is greater than 1 the result is wrong by -1

I resolved this by doing if ( y > 1) {result = result +1 } but i think it is still u bug .
