Hi Benj,
What is the functions of "App Developer Addon" package in Flowcode 9? "App Developer Addon" support only for SCADA application correct? Please advice?

I would like to buy it Flowcode9 full package other than SCADA which I'm not using at all

Hi Benj,
Thanks, Is there any working example Flowcode for MQTT with ESP8266?

Karthick.

Hi LeighM, Yes. In my Nucleo-F446ZE board, SB144 is OFF and there is no any connection between the SB144 to CN11 pin 25. After I soldered the Short in SB144 now I can access the PC14 Port from CN11 and it is working fine. Even it works with just "GPIOC->PUPDR |= ((1) << (14 * 2U));" C code...

Hi LeighM, Thanks for your great support always. I'm really sorry to say this still PC14 is not working and status always read "0". Now I have try to test the PORTC13 (removed teh RTC OSC disable code) with your pull up C code and it is working fine. I have measured the voltage on PC13 por...

Hi Leighm, Yes. I understand that the Nucleo board has the crystal OSC on the PC14 and PC15. But on my board, this port (PC14) is used as DI (Digital Input). Can you please guide me to solve this issues? Because currently I cannot sense the SOA_DI signal, because my board doesn't have the external p...

Hi LeighM, I'm using our own board and this step always shows low even PC14 port goes high thorugh other switch circuit in my board. Even I have ST Nucleo board in my hand. I tested with Nucleo with the attached simple program in the same port configuration and it also measures "0" always....

Hi Leighm, Accually not necesary. Just need to pull up during Measurment and after that no need to pull down or high impedence. I have compile this code and the response is always "1". When I connect teh PC14 port to GND still status is "1". and I connect the PC14 to 3V still sta...

HI LeighM, Thanks for your help. But it looks like it doesn't work. So I have made only for SOA_DI part and read the PC14 pin status through UART to avoid the confusion. As per my understanding, we need to define the variable in C Code and the variable must be connected to UART Send number component...

Hi Leigh, Thanks for your explanation. But unfortunately, our boards don't have the external pull up resistor in the PC14 GPIO pin. We use this PC14 port as a digital input. Attached is our flowcode and can you please help to add the C code to activate the internal pull-up resistor in only PC14 Port...

Hi BenJ, I need your help about , how to configure the ARM MCU's GPIO pin Input Pull up or Pull Down configuration through Flowcode. Below is the GPIO configuration details. One of our project, we need to make the GPIO(PC14) Input pin must be in Pull up mode to measure the signal. Can you please adv...

Hi Matrix Team, Do you have any idea about to configure Alexa or Google Assistant with ESP12F / ESP8266 components? I would like to control the home appliances through Alexa/Google with ESP series Wifi module. It will be good if you add ESP12F / ESP8266 as target and can easily configure the Alexa v...

Hi Leighm, Can you please help to update STARM_CAL_ADC.c files to auto update system? I have tested and it is working fine. Thanks. Hi, You need to download and use the files I posted earlier ... STARM_CAL_ADC.c goes into directory C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\STARM 32F303VC.fcdx goes int...

Hi LeighM,
Thanks.I followed your instruction and now I can see all the ADC pin's.

Thanks.

Hi LeighM, Today I have tried to develop the ADC for STM32F303VCT6 MCU and I found that, all ADC pin's are not enabled. Because STM32F303VCT6 has 39 ADC channels. but our Flowcode shows only 9 ports. Can you please help to modify the same? https://www.st.com/resource/en/datasheet/stm32f303cb.pdf Kar...

HI LeighM,
Can you please update the ADC ports for STM32F303VCT6 component too? I will check with our product and update you on the test result. Thanks.

Karthick.

Actually there is no external OSC present in the STM32F446 Nucleo board. As per datasheet, the STM32F446ZET6 chip has the internal oscillator (Internal 16 MHz factory-trimmed RC (1% accuracy)) and that is 16Mhz. So I choose 16Mhz.

HI LeighM,
Yes. ADC is working fine with STM32F446ZCT6 ARM MCU. I can read the ADC value through UART. You can modify the ADC for other MCU's. Thanks.

Karthick.

HI LeighM, Thanks Again. Yes, you are right. I forget to select the port. I thought when I select the Channel 2 -USART2, Flowcode define the pins automatically. After defining the PD5 for Tx and PD6 for Rx and now working fine. But it is not working with software mode and manual define ports. Thanks...

Hi Alkaline/LeighM, Attaches is the response from STM32 MCU's UART port. I get some junk characters instead of numerical data. I have tried to build using USART2 port, but there is some error if I choose pre-configured USART or UART ports directly. If I choose software mode and I define the RX and T...

HI LeighM,
If you update the STM32F446ZET6 parts similar like STM32F446ZCT6, I can test it now in my home and update you on the result immediately.
I have STM32F446 Nucleo board on hand and I can test now. Please check.

Thanks
Karthick.

Hi LeighM, Thanks. I downloaded .FCDX file into the specific folder and now I can see all the ADC pins for STM32F446ZCT6 part. I will check ADC tomorrow and update you the result. Also I verified all STM32F446ZET6 and STM32F446 Nucleo discovery board (Which has STM32F446ZET6 Chip)component and these...

Hi LeighM, Today I have started developing the code for analog channels with STM32F303VCT6 components and I found some mismatch in ADC pins. Please help to check. Below are the details: As per datasheet STM32F303VCT6 MCU has 39 channel ADC. But Flowcode component has only 9 Ch ADC. In our project, w...

Hi Alkaline, Thanks. I also used Termite 3.4 and i get the junk characters. I 'm not getting what I expected. Can you please review the attached code and advice where I have made the mistake? I guess we need to invert the RX-TX signal through MAX232. Now I just increase the count for every 500ms and...

Hi LeighM,
Done. Thanks. Please help with these 2 topics.

Karthick.

Hi LeighM, Thank you very much for your fast reply. Now I changed into the new topic. :D Also, I need another help. How to communicate the ARM MCU's UART port component directly through FDTI TTL UART adaptor (without using MAX232 IC)? I have tried to communicate but FDTI receives wrong Data. If MCU ...
