Hi, I have a problem. I’m building a project sourced from GitHub. The code used in the project is loaded into the Arduino IDE. In comparison to this project, I’m using Heltec V3 instead of V2. They have the same pins. However, when I upload the code, nothing is displayed on the screen. Information is displayed in the monitor. Does anyone know how I should connect Heltec V3 with the CC1101 module? Link to the project here: https://github.com/c-logic/tpms_toyota

In spite of the implication from the naming, the V2 and V3 boards are very different. You should probably first check the pinout diagrams for the two boards. While some of the pins have the same functions, most do not and are connected to entirely different GPIOs.
If you search this forum for variations on the V2 and V3 board names, you will find many threads discussing the differences.
Do you know how to connect Heltec V3 with the CC1101 module?
The short answer is “No”, but it looks like a pretty standard SPI interface with a couple of data lines. The
relevant pins are all defined in the globals.h file, so I wouldn’t have thought it would be too much of a problem to modify them in line with the relevant V3 pin numbers.
