Re: Problem with 0.96" TFT display ST7735
There is also another thing that made me curious. The blue and red colors are switched. When selecting the red color, the blue color appears. When selecting the blue color, the red color appears. Does this happen with your displays too?

Re: Problem with 0.96" TFT display ST7735
Hi Martin, I was actually thinking about this possibility. Your test reinforces this possibility. I have ordered different samples to test, but your information is very helpful to me. I really appreciate your input.

Problem with 0.96" TFT display ST7735
I recently received some 0.96" ST7735S TFT displays and decided to test them. In the picture of the display you can see that the available communication pins are SCL-SDA-RES-DC-CS-BLK, but in FlowCode the available pins are MOSI-MISO-CLK-RES-DC-CS-BLK. So, I connected them as follows: CLK -----...

Problem with 1.3 inch TFT display ST7789
I was trying to use the display shown in the photo, but something wasn't working right. As simple as my code is, it doesn't work properly. I'm using an Arduino UNO. The problem: After the code is sent to the Arduino, the display remains without information. But, when I send the code to the Arduino a...

Free Arduino Mega 2560. Why not?
I was thinking about the use of Arduinos nowadays. I usually use STM32, because they are cheaper and more competitive. However, I see that two very famous Arduino models are the Arduino Uno and Arduino Mega. I know that FlowCode now offers free support for the Arduino Uno, but the Arduino Mega is st...

Re: Data transmission between 2 STM32 microcontrollers
So it is not possible to communicate with two peripherals on a single UART channel (Short distances)?

Re: Data transmission between 2 STM32 microcontrollers
I also have another question: I'm using a STM32F401RET6 and it has 6 UART channels. Is it possible to make more than 6 slave microcontrollers using just one master board?

Re: Data transmission between 2 STM32 microcontrollers
Hello. I really appreciate your participation in clarifying my question. The communication used between the two STM32 microcontrollers must be bidirectional.

Data transmission between 2 STM32 microcontrollers
Hello everyone.
I want to communicate between 2 STM32 microcontrollers and I'm having some difficulties doing so.
At first, I don't think I know the correct way to do this.
What tool should I use for this? UART? (CAL or RS232?), SPI?
I apologize for my many doubts.
