PowerBoard25

This is the Powerboard for UB SEDS 2025 IREC

Using STM32CubeIDE, we need to convert these drivers from the old firmware:

• LTC2990 Driver

What we still need to implement:

• Powerboard logic
• CAN

How to use LTC2990 Driver:

To use, first init the chip with:

Init function:
int LTC2990_Init(LTC2990_Handle_t *handle, I2C_HandleTypeDef *hi2c);

ex. usage:
LTC2990_Init(&LTC2990_Handle, &hi2c2)

Next, step to get the latest voltage values:

Step function:
void LTC2990_Step(LTC2990_Handle_t *handle);

ex. usage:
LTC2990_Step(&LTC2990_Handle);

To get these newly collected values use LTC2990_Get_Voltage This function will not return the voltages, instead, initialze an array in the main.c with the voltages values you want to store. Pass a pointer to that array in the function:

Get Voltages function:
void LTC2990_Get_Voltage(LTC2990_Handle_t *handle, float* voltages);

ex. usage:
float voltages[4];
LTC2990_Get_Voltage(&LTC2990_Handle, voltages);
