Functions
uint8_t	EPS_send_cmd_get_response (const uint8_t cmd_buf[], uint8_t cmd_buf_len, uint8_t rx_buf[], uint16_t rx_buf_len)
	Sends a command to the EPS, and receives the response.
uint8_t	EPS_run_argumentless_cmd (uint8_t command_code)
	Sends an argumentless command to the EPS (expecting no data in the response).

EPS_send_cmd_get_response()

uint8_t EPS_send_cmd_get_response	(	const uint8_t	cmd_buf[],
		uint8_t	cmd_buf_len,
		uint8_t	rx_buf[],
		uint16_t	rx_buf_len )

Sends a command to the EPS, and receives the response.

Parameters

cmd_buf	Array of bytes to send to the EPS, including the command code, STID, IVID, etc.
cmd_buf_len	Exact length of the command buffer.
rx_buf	Buffer to store the response. Is filled with the response, without tags.
rx_buf_len	Length of the response buffer. Must be the command length.

Returns

0 on success, >0 if error.
