There is 10k potentiometer on input. RealTerm UART/USB terminal connected to RX,TX. 0,500 gives Byte values from 36 to 41 1,000V gives Byte values from 80 to 84 2,00V gives Byte values from 167 to 171 3,00V gives Byte values from 251 to 255 Voltage is very stable. Byte value changes a little every s...

Hi,
I will do this of course. Thanks for suggestion.

Hi LeighM
Still works as before. I will replace the chip, and try also on new STM.
*** After chip replacement everything works as before.

Hi Benj, Thanks for quick reply. I checked some configurations of ADC. GetByte() gives the same result. I got some projects on diferent STM microcontrollers. They works great. VDD=VDDA=3V. Normally I'm using RawAverageInt(16,1000). I also tried to change prescaler and PLL. You are specialist in that...

Hello, Last time i tried to make something on the cheapest version from STM family: STM32F030F4. I just bulild a simple prototype and tried to measure input voltage on PA5 pin (10k poentiometer between GND and 3V). Because i got some problem with correct measurement, I wrote a simple program to chec...

Hi Benji,
What can I say, I hink I have to send a bottle of something strong for that help.
Component added. All macros are active. HEX file created succesfully.
Thanks so much for support.
A lot of health for all Matrix team.

Thanks so much. I will wait for information from You.

My chip packs are shown below. Should I reinstal it?

Hi LeighM,
Something is wrong with my Flowcode7
This option looks like this:

Hi Stefan,
I understand, but I'm afraid the reason is little different.
I have no any parameters to display and modify.
Your screen is from Flowcode 8 right?

Hello, I try o add Timer component to my program and do something on it. When I put the Timer component and some macro (fo example Timer1::StartCounter()) i got problem during compilation. I can't create a HEX file even the code is very simple. License it's a Professional version. Could you help or ...

Hello, Everything is clear. First UART data bits shoud be set to 9. Next your C code shoud be paste after the UART1::Initialise For EVEN mode: HAL_UART_DeInit(&MX_UART_NUMBER_1); MX_UART_NUMBER_1.Init.Parity = UART_PARITY_EVEN; HAL_UART_Init(&MX_UART_NUMBER_1); For ODD mode: HAL_UART_DeInit(&MX_UART...

Hi, Many thanks for it. I will add it soon, test with USB/UART conveter and write an information about result.

Hello. Maybe my topic isn't new, because I want to fix parity bit in my application, but I need some help to solve the problem correctly. Benji wrote a little abut that in older posts. Port settings should be modified to 9-bit, but also adding some calculations are necessary. Because I'm using circu...

Sorry for adding HEX file. Here is corect one.

Hi, I tested interrupt from UART5 RX pin for STM32F030RC on friday evening. I need some help with this. I wrote new simple program: Bluetooth module connected to Channel3-USART3, TXpin- PC.10, RXpin- PC.11; UART to RS485 converter (VP3082) connected to Channel1-USART1, TXpin- PB.6, RXpin- PB.7, flow...

Hello, I promise to write something about modification for STM32F030RC - file from LeighM. I checked interrupt from UART3 RX pin and it works very well. I connect TX to PC.10 and RX to PC.11. Everything works with HC-05 Bluetooth module. I can send and receive data by free BluetoothPro Android appli...

I can't belive... You fix all 6 UART channels :shock: What can I say, you are really a specialist. I can finish my project now. I will receive my board on friday. I will test it and write here about the results. With that all 6 UARTS, STM32F030RC is a very good chip for everyone who want to relize l...

Thanks so much for quick replay LeighM. I got developed PCB with that configuration: UART1 (RS485 for touch panel), UART3 (RS485 for external building automation) and UART5 (bluetooth module). That will be great to get some solution. Datasheets for ARM are much complex for me (before AVR's was used ...

Hello, I'm a new F7 32-Bit ARM user and just start my first projects on this platform. I choose low cost STM32F030RC chip and got some problem with interrupts. There are two interrupts: UART_RXINT1 and UART_RXINT2, which works well for USART1 and USART2 blocks. I need some help to construct interrup...
