I’m writing a firmware for ESP32-S3 and I have problems using the WiFi with an EVE2 display (NHD-7.0-800480FT-CSXV-CTP). I tried to setup a minimal code to reproduce the issue.
#include <stdio.h>
#include <freertos/FreeRTOS.h>
#include <freertos/task.h>
#include <esp_log.h>
#include <nvs_flash.h>
static const char *TAG = "SYS";
void app_main(void)
{
esp_err_t ret = nvs_flash_init();
if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND)
{
ESP_ERROR_CHECK(nvs_flash_erase());
ret = nvs_flash_init();
}
//Display_Init();
Network_Init();
while (1)
{
//Display_Fsm();
ESP_LOGI(TAG, ".");
vTaskDelay(pdMS_TO_TICKS(100));
}
}
here the network functions:
int retry = 0;
EventGroupHandle_t eventGroup;
static void event_handler(void* arg, esp_event_base_t event_base, int32_t event_id, void* event_data)
{
if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_START) esp_wifi_connect();
else if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_DISCONNECTED)
{
if (retry < EXAMPLE_ESP_MAXIMUM_RETRY)
{
esp_wifi_connect();
retry++;
ESP_LOGI(TAG, "retry to connect to the AP");
}
else
{
xEventGroupSetBits(eventGroup, WIFI_FAIL_BIT);
ESP_LOGW(TAG,"connect to the AP fail");
}
}
else if (event_base == IP_EVENT && event_id == IP_EVENT_STA_GOT_IP)
{
ip_event_got_ip_t* event = (ip_event_got_ip_t*) event_data;
ESP_LOGI(TAG, "got ip:" IPSTR, IP2STR(&event->ip_info.ip));
retry = 0;
xEventGroupSetBits(eventGroup, WIFI_CONNECTED_BIT);
}
}
void Network_Init(void)
{
ESP_ERROR_CHECK(esp_netif_init());
eventGroup = xEventGroupCreate();
ESP_ERROR_CHECK(esp_event_loop_create_default());
esp_netif_create_default_wifi_sta();
wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
ESP_ERROR_CHECK(esp_wifi_init(&cfg));
esp_event_handler_instance_t instance_any_id;
esp_event_handler_instance_t instance_got_ip;
ESP_ERROR_CHECK(esp_event_handler_instance_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &event_handler, NULL, &instance_any_id));
ESP_ERROR_CHECK(esp_event_handler_instance_register(IP_EVENT, IP_EVENT_STA_GOT_IP, &event_handler, NULL, &instance_got_ip));
wifi_config_t wifi_config =
{
.sta =
{
.ssid = EXAMPLE_ESP_WIFI_SSID,
.password = EXAMPLE_ESP_WIFI_PASS,
.threshold.authmode = WIFI_AUTH_WPA2_PSK,
//.sae_pwe_h2e = ESP_WIFI_SAE_MODE,
//.sae_h2e_identifier = EXAMPLE_H2E_IDENTIFIER,
},
};
ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_STA, &wifi_config));
ESP_ERROR_CHECK(esp_wifi_start());
ESP_LOGI(TAG, "wifi_init_sta finished.");
}
here the display functions:
void Display_Init(void)
{
EVE_init_spi();
EVE_init();
// Draw static stuff and save to G-RAM
EVE_cmd_inflate(MEM_LOGO, LOGO_SMALL, sizeof(LOGO_SMALL));
drawStaticHeader();
drawStaticPageMain();
drawStaticPageAdvanced();
}
void Display_Fsm(void)
{
ESP_LOGI(LOG, "!");
handleTouch();
displayListBegin();
appendFromRam(MEM_DL_HEADER, num_dl_static_header);
appendFromRam(MEM_DL_PAGE_MAIN, num_dl_static_page_main);
drawTopBar();
drawTopButtons();
drawGloveStatus();
drawNavigationButtons();
displayListEnd();
}
The draw functions are quite long, I don’t know if I need to post them all.
Anyway, here the description of the issue:
-
if I run the display functions only all works fine: the display is updated correctly and I see the
.and!debug symbols on the terminal -
if I run the network functions only all works fine: I see the
.symbol and the WiFi connections debug strings -
if I enable both functions, the display is updated few times, then when the WiFi is activated

as you can see after few seconds all the debug symbols are not printed anymore and the wdt is triggered because is hangs inside:
void EVE_execute_cmd(void)
{
while (EVE_busy() != E_OK)
{
taskYIELD();
}
}
it does not depend on the functions I use to draw on the display.
I read the documentation about SPI master and I don’t see anything about conflicts with the WiFi.
Here the configuration of the display:
add_definitions(
-DEVE_CS=GPIO_NUM_14
-DEVE_PDN=GPIO_NUM_47
-DEVE_SCK=GPIO_NUM_11
-DEVE_MISO=GPIO_NUM_12
-DEVE_MOSI=GPIO_NUM_13
-DEVE_ROTATE=2
-DEVE_BACKLIGHT_FREQ=1000
-DEVE_BACKLIGHT_PWM=10
-DEVE_NHD_70)
Is there anything that would prevent the use of the WiFi with the SPI master?
