STM32F401_TF_LUNA_I2C_HAL
STM32F401CCU6 Blackpill
Based on Arduino... https://github.com/budryerson/TFLuna-I2C
STM32 F4 FW 1.26.2
STM32CubeIDE v1.7.0
HAL
Supported multiple devices on one i2c line.
Printf debugging and SWV, you should watch the video : https://youtu.be/sPzQ5CniWtw
ARDUINO SLAVE ADDRESS
Arduino (IDE only… not the mcu) uses 7 bit addressing system and the rest (including STM32) uses 8 bits.
Whenever you are using the I2C address, use the full 8 bits for the address.
You can find the address for your device in it’s datasheet.
The device 7 bits address value in datasheet must be shifted to the left .
Slave address has been already shifting to the left in the library.
Welcome to the real world :D
How to use this Library:
- Enable I2C normal or fast speed.
- Include Header and source into your project.
#include "tfluna_i2c.h"
TF_Luna_Lidar TF_Luna_1;
int16_t tfAddr = TFL_DEF_ADR; // default I2C address = 0x10 (7 bit)
uint16_t tfFrame = TFL_DEF_FPS; // default frame rate
// device variables passed back by getData
int16_t tfDist = 0 ; // distance in centimeters
int16_t tfFlux = 0 ; // signal quality in arbitrary units
int16_t tfTemp = 0 ; // temperature in 0.01 degree Celsius
// other device variables
uint16_t tfTime = 0; // devie clock in milliseconds
uint8_t tfVer[3]; // device version number
uint8_t tfCode[14]; // device serial number
// sub-loop counter for Time display
uint8_t tfCount = 0;
int main()
{
TF_Luna_init(&TF_Luna_1, &hi2c1, 0x10); //0x10->7bit. 7bit Slave address has been already shifting to the left in the library.
while(1)
{
getData(&TF_Luna_1, &tfDist, &tfFlux, &tfTemp);
printf(tfDist); // Open your SVW ITM Data Console
HAL_Delay(4); // 250Hz
// HAL_Delay(10); // 100Hz
}
}
