I2C #27

Closed BLavery closed 7 years ago

BLavery commented 7 years ago

I am trying to port the SPI example of oled SSD1306 to use i2c instead. I haven't succeeded yet. I am suspicious that this call: defprimitive "i2c-write-slave" at line 550 in ext.S of punyforth is missing one of the 4 parameters of the corresponding C call int i2c_slave_write() at line 120 in i2c.h at https://github.com/SuperHouse/esp-open-rtos/blob/master/extras/i2c/i2c.h

Am I missing something? I do hope I don't have to set up to recompile punyforth, just for a 1-line change to ext.S

Earlier i2c_slave_write had 3 parameters, see: https://github.com/SuperHouse/esp-open-rtos/commit/fd1081a0cc1e0f8723087b366aa81750f4638d1f#diff-938bcf30e93ecd659b5e0be1995b2c3d

The punyforth binary should be compiled against the earlier version of esp-open-rtos, so it shouldn't be the problem, but I'll double check it.

Yes it has 3 parameters in that build, so this shouldn't be the problem. What kind of error do you get?

I've just tested the i2c with a wemos oled shield and it worked fine. Closing this.
