Would be nice if someone knows how to add this device to the Keil IDE.
Does the information here help add it to KEIL?
https://github.com/iclite/mm32_startup/tree/master
Would be nice if @WizzardDr would explain how he added the GD32E230 target to the project:
If a new target would be added, then your MM mcu can be choosen:
Then this repo might already compile. It might need some fixes like fore the E230 mcu in target.h
#ifdef GD32E230
#include "gd32e23x.h"
#define TARGET_nvic_irq_enable(a, b, c){nvic_irq_enable(a, b);}
#define TARGET_nvic_priority_group_set(a) // that function does not exist for this target = not needed ?
#define TARGET_adc_vbat_disable()
#else
#include "gd32f1x0.h"
#define TARGET_nvic_irq_enable(a, b, c){nvic_irq_enable(a, b, c);}
#define TARGET_nvic_priority_group_set(a){nvic_priority_group_set(a);}
#define TARGET_adc_vbat_disable(){adc_vbat_disable();}
#endif
But as WizzardDr succeeded with adding a new target, i now am quite optimistic that he and me could add your MM mcu and i/we resolve all compiler errors.
But are you willing to invest some hours to trace the pins ??
Okay, a target can be added in menu->Project->Manage->ProjectItems..
But now i am stuck at adding the Device files and i do not know the name of the propper #include file:
ideas welcome.
When I look at my board it is slightly different than this board, appears to have the same processor though.

Slave Board Identifiers Taotao Technology 2025 pu20200616011 94v-0 y-d e253642 816117r
To me this looks identical to the photos of the first board.
But i have no idea from where to get the MM counterplay of the Standard Peripherals:
I have nearly zero experience with the Keil Ide :-/
Adding some documentation

Yes thanks, i have added the pdf documents to the manuals folder. But i fear we still do not know how to install the Standard Peripherals like ADC, DMA, GPIO

Looking for help on this board. I've burned through many of the RioRand motor controllers and decided to use one of the 4 different hoverboard motors that I have. Any help will be appreciated. I'm a newbie, but I love tinkering and learning new things.
If you have different boards you better start with a GD32F130 MCU and not this not yet supported MM32SPIN05.
I do have a GD32F130 C8T6 MCU board, but it's a newer board and does not match any of the examples. I wasn't sure if I could flash or not since it didn't exactly match. If I can, then that will be perfect since that's the board and motor that I want to use.
No you need to start a new issue here, upload high res photos of front and backside and start tracing the pins. See the 2.6.1 issue currently being active. This 2.8 is not yet traced either.
I always like to add new layouts, so feel free to go ahead :-)
@RoboDurden heres a toturial of using keil with mm32spin maybe itll help i cannot tell mm32spinexample(changeZIPto7Z).zip MM32_KEIL_Pack_2.18.zip

i am not sure if this is your problem but i think you can copy it from example
@RoboDurden can you please look into it now i have included the new build target
it still have 83 error but those are related to constant not defined can you fix them
#50
Thanks for you work ! I have accepted the pull request :-) But i did not like that you changed
#ifndef ADC_BATTERY_VOLT
#define ADC_BATTERY_VOLT 0.024169921875
to
#ifndef ADC_BATTERY_VOLT
#define ADC_BATTERY_VOLT 0.02488682634 // V_Batt to V_BattMeasure = factor 30: ( (ADC-Data/4095) *3,3V *30 )
This would apply to all other layouts and not only the 2.6. Instead i will add
#define ADC_BATTERY_VOLT 0.02488682634 // V_Batt to V_BattMeasure = factor 30: ( (ADC-Data/4095) *3,3V *30 )
to the defines_2-6.h
i have uploaded my first changes, so please @AILIFE4798 sync your code.
#ifdef GD32E230
#define LAYOUT 7
#elif MM32SPIN05
#define LAYOUT 8
#else
#define LAYOUT 6
#endif
//#define MASTER // uncomment for MASTER firmware. Choose USART0_MASTERSLAVE or USART1_MASTERSLAVE in your defines_2-?.h file
//#define SLAVE // uncomment for SLAVE firmware. Choose USART0_MASTERSLAVE or USART1_MASTERSLAVE in your defines_2-?.h file
#define SINGLE // uncomment if firmware is for single board and no master-slave dual board setup
Looks like many files in the Inc project folder should not be there. Maybe you can fix this:
I am down to 75 errors and 0 warning. Many errors are to my PB8 -> PORT_B + PIN_8 marcors that i introduced lately to make the defines_2-x.h easier. But these macros are GD32 specific so i now first have to investigate how MM is coding PORT and PIN. This might take some hours.
I am still struggeling to get water and electricity running in my autarcic train station:
It is -7°C outside (10:44 o' clock)
yes,the adc calibration should be done on every board because the resistors and mcus are not exactly identical
you can delete those files in inc its not needed
i am just experimenting with it and those file is included in device already
do you have real hardware layout2.8 to test on or should i buy more of them to test because the real problem will start from how to flash it
MM is also using port defines like GPIOB but not pin defines like GPIO_PIN_9 :-/ So i must learn the defines to acces a port/pin for MM. With GD32 the GPIO_PIN_9 is defined in gd32f1x0_gpio.h:
/* GPIO pin definitions */
#define GPIO_PIN_0 BIT(0) /*!< GPIO pin 0 */
#define GPIO_PIN_1 BIT(1) /*!< GPIO pin 1 */
#define GPIO_PIN_2 BIT(2) /*!< GPIO pin 2 */
#define GPIO_PIN_3 BIT(3) /*!< GPIO pin 3 */
#define GPIO_PIN_4 BIT(4) /*!< GPIO pin 4 */
#define GPIO_PIN_5 BIT(5) /*!< GPIO pin 5 */
#define GPIO_PIN_6 BIT(6) /*!< GPIO pin 6 */
#define GPIO_PIN_7 BIT(7) /*!< GPIO pin 7 */
#define GPIO_PIN_8 BIT(8) /*!< GPIO pin 8 */
#define GPIO_PIN_9 BIT(9) /*!< GPIO pin 9 */
#define GPIO_PIN_10 BIT(10) /*!< GPIO pin 10 */
#define GPIO_PIN_11 BIT(11) /*!< GPIO pin 11 */
#define GPIO_PIN_12 BIT(12) /*!< GPIO pin 12 */
#define GPIO_PIN_13 BIT(13) /*!< GPIO pin 13 */
#define GPIO_PIN_14 BIT(14) /*!< GPIO pin 14 */
#define GPIO_PIN_15 BIT(15) /*!< GPIO pin 15 */
#define GPIO_PIN_ALL BITS(0,15) /*!< GPIO pin all */
The PORT definitions for MM are in reg_gpio.h :
#define GPIOA ((GPIO_TypeDef*) GPIOA_BASE)
#define GPIOB ((GPIO_TypeDef*) GPIOB_BASE)
#define GPIOC ((GPIO_TypeDef*) GPIOC_BASE)
#define GPIOD ((GPIO_TypeDef*) GPIOD_BASE)
But i can no identify the PIN definitions yet. Maye a MM32 code example would help
I think i have 2.8 but not here in the train station i think. And honestly i do not have the time=happiness at the moment to build yet another test setup. So it would be great if you had 2.8 hardware. Was $2 a typo or can you really buy fully assembled 2.8 boards for USD 2 ???
Maybe these are the definitions we need: https://github.com/koendv/MM32SPIN27-Arduino/blob/525f27bd91b756aeabad3b7a706f60cb9fb75275/mm32/cores/arduino/HAL_Lib/hal_gpio.h#L89
But i would like to find these defines in the target files you added.
here is a example of mm32 blynk
$2 is for a pair of master and slave layout2.8.1 board by razor no led or motor i think its hard to beat heres a link not sure if you can open it outside of china if not you have to use VPN https://m.intl.taobao.com/detail/detail.html?id=722577319258 a set of gen1 board with mainboard+2 side board+led board is $12 still cheap(seller say its full GD32 so compatiable with eferu) keep in mind its china everything is dirt cheap
Where can i download this blynk example ?
We have problems to port the EFeru gen1 firmware to the newer AT32 Gen1 boards ! So if there is no GD32 mcu on theser $12 boards i would be caucious.
yes i have also seen the at32 board its selling for even cheaper but i know its not supported so i wont try to buy it it is very easy to identify by theres no mcu on the side board every single gpio goes to the main board so the main board to side board cable is very wide idk how they get so much gpio from just one mcu maybe with multiplex idk
Incase you cannot open the link I downloaded the image from seller for you to confirm layout 2.8.1
Well this is definitely not a 2.8 layout. See my photos in Schematics_2.8/ folder.
I do not find the gpio_bit_write() definition for the MM target. When i search my project with strg+shift+F i only find the GD definition :-/ This would help me to cast PA6 to the correct types ..
48 errors. code uploaded. i have to make a break. sun is finally shining so i can saw some wood to feed my oven ! It is currently -6°C outside and +11°C inside !
