SPC58EC80E5 , how to work on serial recevier
I’m working on SPC58EC80E5 in autodevkit studio , serial tranmitter is working but serial recevier is not working , i attachesd the serial driver coniguration check it and also my main.c is below
#include "components.h"
#include "serial_lld_cfg.h"
#include <stdio.h>
#include <string.h>
uint8_t ch;
char buffer[20];
uint8_t idx = 0;
int value = 50;
/* ── Strip \r and \n from string ── */
static void stripNewlines(char *str)
{
int i = 0, j = 0;
while (str[i] != '\0')
{
if (str[i] != '\r' && str[i] != '\n')
str[j++] = str[i];
i++;
}
str[j] = '\0';
}
int main(void)
{
char msg[50];
componentsInit();
irqIsrEnable();
sd_lld_start(&SD12, &serial_config_configuration_name);
sd_lld_write(&SD12,
(uint8_t *)"UART Ready. Send number like 120#\r\n", 35);
while (1)
{
if (sd_lld_read(&SD12, &ch, 1) == 1)
{
/* ── ignore \r and \n completely ── */
if (ch == '\r' || ch == '\n')
{
/* do nothing, discard */
}
else if (ch == '#')
{
buffer[idx] = '\0';
idx = 0;
stripNewlines(buffer);
int newValue;
if (sscanf(buffer, "%d", &newValue) == 1)
{
snprintf(msg, sizeof(msg),
"Prev = %d | Curr = %d\r\n", value, newValue);
value = newValue;
sd_lld_write(&SD12, (uint8_t *)msg, strlen(msg));
}
else
{
sd_lld_write(&SD12,
(uint8_t *)"[ERROR] Send digits only, like 120#\r\n", 37);
}
}
else
{
if (idx < sizeof(buffer) - 1)
buffer[idx++] = ch;
}
}
osalThreadDelayMilliseconds(10);
}
}
