Setting SPI register SPI_DIN_MODE_REG and SPI_DIN_NUM_REG is not possible
Posted: Fri Nov 10, 2023 1:27 pm
In my code I would like to set the register to delay the MISO line on SPI3. Therefore I use the following code:
I'm not able to write to these register. They stay 0x00000000 the whole time.
Also in the current ESP-IDF code this section is empty:
https://github.com/espressif/esp-idf/bl ... _ll.h#L864
Is it possible to write to these register?
Kind regards
Code: Select all
uint32_t test_mode = 0x00000001;
uint32_t test_num = 0x00000001;
uint32_t volatile * const p_din_mode_reg = (uint32_t *) 0x60025024;
*p_din_mode_reg = test_mode;
uint32_t volatile * const p_din_num_reg = (uint32_t *) 0x60025028;
*p_din_num_reg = test_num;
if(*p_din_num_reg != test_num)
{
ESP_LOGI(TAG, "p_din_num_reg: %4x", (unsigned int)*p_din_num_reg);
return ESP_FAIL;
}
if(*p_din_mode_reg != test_mode)
{
ESP_LOGI(TAG, "p_din_mode_reg: %4x", (unsigned int)*p_din_mode_reg);
return ESP_FAIL;
