Send byte by slave i2c #8

Hi!

I'm trying to implement a model similar to a memory, where the RA-08 is an i2c slave, receiving a register and returning the corresponding value, but the application gets stuck in while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_TRANS_EMPTY) != SET);

Here the code:

/ wait slave address detected / while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_SLAVE_ADDR_DET) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_SLAVE_ADDR_DET);

/ read RW byte / i2c_set_receive_mode(I2C_SLAVE_NUM, I2C_ACK); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL); board_data->buff.rw = i2c_receive_data(I2C_SLAVE_NUM);

/ read Data Len byte / i2c_set_receive_mode(I2C_SLAVE_NUM, I2C_ACK); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL); board_data->buff.len = i2c_receive_data(I2C_SLAVE_NUM);

/ read Reg byte / i2c_set_receive_mode(I2C_SLAVE_NUM, I2C_ACK); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL); board_data->buff.reg = i2c_receive_data(I2C_SLAVE_NUM);

/ wait slave address detected / i2c_set_receive_mode(I2C_SLAVE_NUM, I2C_ACK); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_RECV_FULL); i2c_receive_data(I2C_SLAVE_NUM);

i2c_send_data(I2C_SLAVE_NUM, 3); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_TRANS_EMPTY); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_TRANS_EMPTY) != SET);

i2c_send_data(I2C_SLAVE_NUM, 1); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_TRANS_EMPTY); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_TRANS_EMPTY) != SET);

/ wait slave stop detected / i2c_set_receive_mode(I2C_SLAVE_NUM, I2C_ACK); while (i2c_get_flag_status(I2C_SLAVE_NUM, I2C_FLAG_SLAVE_STOP_DET) != SET); i2c_clear_flag_status(I2C_SLAVE_NUM, I2C_FLAG_SLAVE_STOP_DET);

Grateful for any help!
