Hello,
Currently, I command the sensor with "SendScriptToDevice(Linear_Sweep);" function like that.
char const * Linear_Sweep= "e\n"
"var c\n"
"var p\n"
"set_pgstat_mode 3\n"
"set_max_bandwidth 200\n"
"set_range ba 500u\n"
"set_e -500m\n"
"cell_on\n"
"wait 1\n"
"meas_loop_lsv p c -500m 500m 50m 100m\n"
"pck_start\n"
"pck_add p\n"
"pck_add c\n"
"pck_end\n"
"endloop\n"
"cell_off\n"
"\n";
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration--------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */

/* Initialize interrupts */
MX_NVIC_Init();
/* USER CODE BEGIN 2 */
HAL_UART_Receive_IT(&huart3, RX_Data, 1);
SendScriptToDevice(Linear_Sweep);
But now, I want to updated certain numbers in Linear_Sweep with UART receiving. To implement this idea, I wrote the codes like that but it didn't work. Do you have a suggestion about the problem?
