Hi Alberto

txs, nice nice work!!

please have a note:
( see my last post in second part)

Code: Select all

..
#define PERIPHS_IO_MUX_MTCK_U (DR_REG_IO_MUX_BASE +0x38)
#define FUNC_MTCK_U0CTS 3
#define FUNC_MTCK_GPIO13 2
#define FUNC_MTCK_HSPID 1
#define FUNC_MTCK_MTCK 0
..


pad 16 ( GPIO 13, HSPID, MTCK... ) is named U0CTS too, perhabs you have overlook.
or is this wrong in header file in the RTOS, have not seen a update in the
RTOS, so i think, the U0CTS is still on PAD 16 ( GPIO13 ).

best wishes
rudi ;-)

and sure, here is the long talk with CEO Teo Swee-Ann:
http://makezine.com/2015/12/09/meet-esp ... d-esp8266/
and read the nice talk! - we have nice infos in this "whisper talk" - i like this art so much ! we will get all infos, we must open our eyes and ears.. and we will have most infos before espressif post document here, i like this game :P



best wishes

not 100 procent sure ( 99,99 procent ) , think ethernet?!
but please do not beat to me if wrong :oops:

"RMII is a reduced version of the Media Independent Interface (MII). The reduction refers in RMII to the number of transmission lines and the number of pins that is 8 instead of 16th In order to guarantee the data rates of 10 Mbit / s and 100 Mbit / s, as RMII MII works with the SDR-process in which an edge of the clock signal are used for data transmission. However, the clock rate of 25 MHz must be increased to 50 MHz."

rudi ;-)

EDIT:
ups... i think i have not read your question right,
do you ask for the place on Modul/Chip
or ask for the place of #define Code or do you ask, what with RMII is mean?
Sorry - i have read, you want to know what RMII is..
usually in one header here
https://github.com/espressif/ESP32_RTOS ... /espressif
https://github.com/espressif/ESP32_RTOS ... ssif/esp32
but think, there is no header just in time availabel, same to BTLE, i think.
please correct me the think is mistake, but i have not search the RMII mux just in time and my thinking was going because BTLE would be later timer availabel.

Edit:
i read just in time here a small and puzzle:
https://github.com/espressif/ESP32_RTOS ... /rmt_reg.h
and here:
https://github.com/espressif/ESP32_RTOS ... _sig_map.h

Code: Select all

..
#define RMT_SIG_IN1_IDX   84
#define RMT_SIG_IN2_IDX   85
#define RMT_SIG_IN3_IDX   86
..
#define RMT_SIG_OUT0_IDX   87
#define RMT_SIG_OUT1_IDX    88
#define RMT_SIG_OUT2_IDX   89
#define RMT_SIG_OUT3_IDX   90
#define RMT_SIG_OUT4_IDX   91
#define RMT_SIG_OUT5_IDX   92
#define RMT_SIG_OUT6_IDX   93
#define RMT_SIG_OUT7_IDX   94

hi Alberto
txs,
can u say, which base you take, mean you with
GPI only direction is Input ?
GPO only direction is Output ?
GPIO direction is In and Output ?

Example Rev 1.3:
( GPO32, GPO33 , GPI35 ..)

Please have a look here:

Code: Select all

/**
* @brief Enable GPIO pin intput,This function only config GPIO0-GPIO31.
* @param gpio_bits : The GPIO bit number.
* @return null
*/
#define GPIO_AS_INPUT(gpio_bits) gpio_output_conf(0, 0, 0, gpio_bits)
/**
* @brief Enable GPIO pin intput,This function only config GPIO32-GPIO39.
* @param gpio_bits : The GPIO bit number.
* @return null
*/
#define GPIO_AS_INPUT_HIGH(gpio_bits) gpio_output_conf_high(0, 0, 0, gpio_bits)
/**
* @brief Enable GPIO pin output,This function only config GPIO0-GPIO31.
* @param gpio_bits : The GPIO bit number.
* @return null
*/
#define GPIO_AS_OUTPUT(gpio_bits) gpio_output_conf(0, 0, gpio_bits, 0)
/**
* @brief Enable GPIO pin output,This function only config GPIO32-GPIO39.
* @param gpio_bits : The GPIO bit number.
* @return null
*/
#define GPIO_AS_OUTPUT_HIGH(gpio_bits) gpio_output_conf_high(0, 0, gpio_bits, 0)



Code: Select all

we have GPIO0 - GPIO39 In and Output
Input      GPIO0  - GPIO31
Output       GPIO0  - GPIO31
Input High   GPIO32 - GPIO39
Output High   GPIO32 - GPIO39


found here:

https://github.com/espressif/ESP32_RTOS ... ude/gpio.h

best wishes
rudi ;-)

btw
GPIO Pin 24, 28-31 are not defined / special

Code: Select all

#define GPIO_Pin_22 (BIT(22)) /* Pin 22 selected */
#define GPIO_Pin_23 (BIT(23)) /* Pin 23 selected */
//#define GPIO_Pin_24 (BIT(24)) /* Pin 24 selected */
#define GPIO_Pin_25 (BIT(25)) /* Pin 25 selected */
#define GPIO_Pin_26 (BIT(26)) /* Pin 26 selected */
#define GPIO_Pin_27 (BIT(27)) /* Pin 27 selected */
//#define GPIO_Pin_28 (BIT(28)) /* Pin 28 selected */
//#define GPIO_Pin_29 (BIT(29)) /* Pin 29 selected */
//#define GPIO_Pin_30 (BIT(30)) /* Pin 30 selected */
//#define GPIO_Pin_31 (BIT(31)) /* Pin 31 selected */
#define GPIO_Pin_32 (BIT(0)) /* Pin 32 selected */


like your work, hope we get docu asap for clear fine
and you can update fine, which software you use for diagramm?
nice work!!

Hi Rudy,

I use Illustrator :)
I have all documentation & infos from Espressif and this weekend I'm study well :)
In the meantime:

The ESP32 chip pinout. Is the chip mounted in ESP32 module.
