Add ESP-C3-M1-I-Kit board #6938

wmjohnanderson · 2022-07-04T13:54:53Z

Summary
PR for ESP-C3-M1-I-Kit board in variants

I am current summer intern learning as much as I can and using this as practice. This is my first time doing this so if there is anything wrong, or any issues let me know and I can work on it. Thanks!

Hi, @wmjohnanderson
Thank you for the contribution.
Could you please rename the folder to create a proper slug name.
Example: from ESP-C3-M1-I-Kit is esp_c3_m1_i_kit
Thank you in advance.

This creates a pins variant but doesn't define any board to use it. Please update boards.txt to have a reference to this new board.

esp_c3_m1_i_kit/pins_arduino.h

+static const uint8_t SS    = 23;
+static const uint8_t MOSI  = 21;
+static const uint8_t MISO  = 22;
+static const uint8_t SCK   = 28;


the above four pins are not recommended for use or do not exist on the ESP32-C3. These should be remapped to valid pins.

@wmjohnanderson - suggestion:

static const uint8_t SS = 5; static const uint8_t MOSI = 10; static const uint8_t MISO = 6; static const uint8_t SCK = 7;

atanisoft · 2022-07-05T12:24:44Z

+static const uint8_t A2 = 4;
+static const uint8_t A3 = 5;
+static const uint8_t A4 = 6;
+static const uint8_t A5 = 13;


GPIO 0 - 5 are the only ADC pins, GPIO 13 does not exist.

@wmjohnanderson - suggestion:

static const uint8_t A0 = 0; static const uint8_t A1 = 1; static const uint8_t A2 = 2; static const uint8_t A3 = 3; static const uint8_t A4 = 4; static const uint8_t A5 = 5;

+
+static const uint8_t LED_BUILTIN = 18;
+static const uint8_t LED_BUILTIN = 19;


Duplicate pin define... which is it?

@wmjohnanderson - suggestion:

static const uint8_t LED_C = 18; static const uint8_t LED_W = 19; static const uint8_t LED_BUILTIN = 19; #define BUILTIN_LED LED_BUILTIN // backward compatibility

Please verify the suggestions and review from @atanisoft in order to move forward.
Thanks!

@wmjohnanderson Any updates so we can move forward with this PR?

@wmjohnanderson Can you help process suggested changes?

+static const uint8_t LED_BLUE = 5;
+
+static const uint8_t TX = 18;
+static const uint8_t RX = 19;


This is the correct pins used in this boards. GPIO18 and 19 are LEDs and USB JTAG/CDC.

static const uint8_t TX = 21; static const uint8_t RX = 20;

SuGlider · 2022-09-06T01:40:00Z

esp_c3_m1_i_kit/pins_arduino.h

+static const uint8_t RX = 19;
+
+static const uint8_t SDA = 4;
+static const uint8_t SCL = 5;


My suggestion based on the boards layout would be:

static const uint8_t SDA = 1; static const uint8_t SCL = 2;

Fixed with standard ESP32-C3 definition.

SuGlider · 2022-09-06T01:41:22Z

This creates a pins variant but doesn't define any board to use it. Please update boards.txt to have a reference to this new board.

@wmjohnanderson - As @atanisoft already said, we also need that you make proper changes to boards.txt in order to add this boards to the list.

SuGlider

@wmjohnanderson - Please check all the pending requested changes.

P-R-O-C-H-Y · 2022-12-02T14:21:27Z

@wmjohnanderson Hi, is this PR still valid as there is no reaction from you for a long time.

SuGlider

Fixed all pending issue in order to move forward and get it merged.

@wmjohnanderson Any updates so we can move forward with this PR?

@VojtechBartoska @P-R-O-C-H-Y - I have searched this board specification and fixed all the pinout definition.
Please review it. ~~I think we can go ahead and get it merge it~~

It still misses modifications to board.txt file.

SuGlider · 2022-12-07T21:29:03Z

@P-R-O-C-H-Y - Please double check it and if it is ready, please merge it. Thanks!

Fixes board.txt file to add the new ESP32_C3_M1_I_KIT variant

SuGlider · 2022-12-08T19:08:14Z

This creates a pins variant but doesn't define any board to use it. Please update boards.txt to have a reference to this new board.

This is done now.

me-no-dev · 2022-12-13T10:03:06Z

Specs say that the module comes with 4MB Flash, so I suggest (strongly) that the unnecessary options are removed (flash size, flash mode, flash freq and partitions that would not fit) 4MB 80Mhz QIO should be default and only option

me-no-dev · 2022-12-13T10:03:47Z

Also this module does not differ in any functional way from the default ESP32-C3 Dev Module

me-no-dev · 2022-12-13T10:06:28Z

@ajsb85 @wmjohnanderson have you tested USB connected to IOs 18 and 19? Does it work OK with the LEDs that you have added?

SuGlider · 2022-12-13T23:14:44Z

@ajsb85 @wmjohnanderson have you tested USB connected to IOs 18 and 19? Does it work OK with the LEDs that you have added?

The board has a CH340. I think it doesn't mind about USB pins.
Maybe it can just disable menu option for CDC.

me-no-dev · 2022-12-14T10:46:11Z

@SuGlider you still have the options for Flash Frequency and Flash Mode, which I find redundant as well. 4MB 80Mhz QIO is all that is needed

SuGlider · 2022-12-14T14:41:35Z

I think it is fine now. Let me know.

ajsb85 · 2022-12-15T11:29:27Z

Hi, @me-no-dev

I will take a look all the features and review the PR in deep with that board.

Thank you very much for the merged into the repo.
