Error compiling JoyC_&_RoverC/Master/Master.ino
-
I try to compile the code from https://github.com/m5stack/M5StickC-Plus/blob/master/examples/KIT/JoyC_%26_RoverC/Master/Master.ino
under Arduino: 1.8.19 (Windows 10), Board: "M5Stick-C-Plus, Default, 1500000, None"
But i get an error:RoverC:88:23: error: 'I2C_ERROR_NO_BEGIN' was not declared in this scope uint8_t IIC_ReState = I2C_ERROR_NO_BEGIN; ^~~~~~~~~~~~~~~~~~ C:\Users\toro\Documents\Arduino\RoverC\RoverC.ino:88:23: note: suggested alternative: 'ESP_ERR_NO_MEM' uint8_t IIC_ReState = I2C_ERROR_NO_BEGIN; ^~~~~~~~~~~~~~~~~~ ESP_ERR_NO_MEM
The answer is in the error, following the suggestion fixes the error.
Now, besides that it works i have no idea if the replacement is correct logically. The Const-Names suggest yes, but there might be more to it...
If the replacement is universally ok, should a github pull request be made?EDIT:
There is an error/warning thrown that i had overlooked.
So, just doing the replacement seems like not enough...RoverC.ino.cpp:1: ...\AppData\Local\Arduino15\packages\m5stack\hardware\esp32\2.0.2/ tools/sdk/esp32/include/esp_common/include/esp_err.h:31:37: warning: unsigned conversion from 'int' to 'uint8_t' {aka 'unsigned char'} changes value from '257' to '1' [-Woverflow] #define ESP_ERR_NO_MEM 0x101 /*!< Out of memory */ ^~~~~ ...\Arduino\RoverC\RoverC.ino:88:23: note: in expansion of macro 'ESP_ERR_NO_MEM' uint8_t IIC_ReState = ESP_ERR_NO_MEM; ^~~~~~~~~~~~~~

@sirtet Change "I2C_ERROR_NO_BEGIN" to "ESP_OK". The git for M5StickC-Plus has already been fixed with this. The fix also works for the M5StickC code.
