Hello, I solve a problem with writing the value to the register of sensor VL53L1X. It is the main purpose, why the sensor doesn´t read distance because the init state is invalid. For example, I tried to write the value 0x2 to the register 0x30 on the...

Hi, I solve a problem with reading more parameters from the inclinometer Murata SCL3300. The communication works without errors, the init state is OK and when I read more parameters, I get the wrong results. For SPI communication I use HAL_SPI_Transm...

The problem with writing values to the sensor registers was caused by a bad BluePill board. The fourth byte of the message was never sent (you can see it at the PrintScreens from the oscilloscope), the clock always dropped after the three byte.When...

@John E KVAM thanks for you answer. The I2C mis-configured is possible. I´m adding the actual configuration. Really long wires are not the cause of this problem. I use the same wires for testing on the Arduino board and it works. Tomas

The problem was in reading data. Responses are shifted as shown in the datasheet. The data reading code should look like this: // first command transfer(RdAngX); if (crcerr || statuserr) errorflag = true; // second command tra...

Hi @Eleon BORLINI ,thanks for your answer and suggestion. I try to add this question on the Murata support page. I use a basic processor STMF103C8T6. I think the problem will be in using the function HAL_SPI_TransmitReceive. The protocol needs to se...
