Arduino for STM32

Hello everyone, I have such a problem, namely I used to fight with the ibus library and I managed to tame it thanks to your help ;) As I bought myself a new radio, I would like to send telemetry to it. The only sensible library I found is: FrSky S-Port telemetry library https://www.rcgroups.com/foru...

Hi, I decided to check if something has changed in Core 2.3 and the IbusBm library. It turns out that the STM32 Core 2.3 version started working ibus Servo but IbusSensor does not work. So I don't have telemetry. I can control e.g. servo motors etc (now i have the correct PWM values which was the pr...

Ok, I found a solution. The problem is the stm32duino ibus sensor works on the old version 1.9.0 on the newer one does not want to work in any way. Is there a chance to solve this problem and where can I report it? This code work on version 1.9.0 but don't work on 2.0.0, 2.1.0, 2.2.0 #include <IBusB...

Hi everyone. I don't know much about electronics, so I have a question. I have a servo that is powered by 5V. At the same time, I power my stm32 via a 5V pin. If I connect the servo in this way to stm32, will I not burn anything or do I need to use a converter? Thank you in advance for the answers f...

it is looking for _VARIANT_ARDUINO_STM32_, i'm not sure if that is the correct way to detect the STM core. so one of those things is maybe you could either try to #define _VARIANT_ARDUINO_STM32_ before your #include "IBusBM.h" to see if it helps When I add this definition, I have a compil...

The worst part is that exactly a year ago, maybe one and a half everything was working on the blackpill STM32F411.
And I did some dumb updates a while ago and it stopped working.
I installed clean windows10 for this arduino IDE earlier versions I only added STM32 and ibusBM. Unfortunately, no success.

Hi all, I have such a problem, namely I want to receive data via iBus from the flysky ia6b receiver. The problem is that I get all 0 instead of specific values. The same code uploaded to ArduinoMega works without a problem and with stm32 it does not want. I tried on the STM32F411 / F401 blackpill, N...

I changed the code but unfortunately to no avail. it works on PB6 / PB7 and in the rest I have the start screen of the display ;( #include <LiquidCrystal_PCF8574.h> #include <Wire.h> TwoWire Wire2(PB3,PB10); TwoWire Wire3(PB4, PA8); LiquidCrystal_PCF8574 lcd(0x27); // set the LCD address to 0x27 for...

Ok, I used a different library and it works. but I have another problem namely how to use a different SDA / SCL pair. When I connect by default in stm32F401 PB7 / PB6 it all works and if I try to use SDA2 / SCL2 or SDA3 / SCL3, it doesn't work. Has anyone encountered such a problem, what could be wr...

Hi everyone, I've been trying for a few days now to try to run the LCD on the stm32f401 but to no avail. The LCD display is: LCD 2004A 4x20 HD44780 green. I connected the PB6 (SCL1) and PB7 (SDA1) + 5V and GND cables. After connecting only the power supply, I adjusted the display so that there were ...
