SSD1327 128X128 I2C MIDAS problem

[jnivard]

Hai

I try to use the SSD1327 display using the I2C interface software reassigned, but it seems that it is not working. I have tryed all the constructors for the following board "SSD1327 msp1503"
// Only one contructor is working properly using the hardware implementation of the I2C protocol on Wemos ESP8266 pin D1 and D2, the hardware implementation I2C fullbuffer

//SSD1327 display msp1503 hardware SDA and SCL is working using the display and WEMOS ESP8266 pin D1 and D2 (GPIO5,GPIO4).
// U8G2_SSD1327_MIDAS_128X128_F_HW_I2C u8g2(U8G2_R0, /* reset=/ U8X8_PIN_NONE); / Uno: A4=SDA, A5=SCL, add "u8g2.setBusClock(400000);" into setup() for speedup if possible */ working

//SSD1327 display msp1503 hardware SDA and SCL is not working at all using a display and WEMOS ESP8266 pin D1 and D2 (GPIO5,GPIO4).
//U8G2_SSD1327_MIDAS_128X128_1_HW_I2C u8g2(U8G2_ noR0, /* reset=/ U8X8_PIN_NONE); / Uno: A4=SDA, A5=SCL, add "u8g2.setBusClock(400000);" into setup() for speedup if possible */ not working

//SSD1327 display msp1503 hardware SDA and SCL is not working using the display and WEMOS ESP8266 pin D5 and D6 (GPIO14,GPIO12).
//U8G2_SSD1327_MIDAS_128X128_1_SW_I2C u8g2 (U8G2_R0,/* clock = /14,/ data = /12,/ reset = */U8X8_PIN_NONE);// not working upper text half, no scrolling text

//SSD1327 display msp1503 hardware SDA and SCL is not working using the display and WEMOS ESP8266 pin D5 and D6 (GPIO14,GPIO12).
//U8G2_SSD1327_MIDAS_128X128_F_SW_I2C u8g2 (U8G2_R0,/* clock = /14,/ data = /12,/ reset = */U8X8_PIN_NONE);// not working upper text ok, no scrolling characters,text area is flashing and blanck

//SSD1327 display msp1503 hardware SDA and SCL is not working using the display and WEMOS ESP8266 pin D5 and D6 (GPIO14,GPIO12).
//U8G2_SSD1327_MIDAS_128X128_F_SW_I2C u8g2 (U8G2_R0,/* clock = /0,/ data = /2,/ reset = */U8X8_PIN_NONE);// not working upper text ok, no scrolling characters,text area is flashing and blanck

I did the same test with a ESP8266Mod board and had the same results. The SSD1327 msp1503 is not working using the software implementation of the I2C protocol and only works only with the full buffer constructor (F)

I have repaited the test using a SSD1306 board and that is working ok

The supplier of the board came to the same result and did advice to use the adafruit SSD1327 library and that is working ok. I think
there is a error in the U8g2 libray for the constructors I named
