On page 11 on Manual 2 it says But in appendix 6 it says there are 512 bytes, and this is what the simulator shows. So how do I access the ram above 256? I tried forum search but got 500 irrelevant threads. EDIT: by further experimentation it appears that bptr is a 9 bit register, and can...

I'm using a 8M2 to read temperature from I2C DS1631 and format as serial data for a remote PC. Simple conversion from published arduino code, but the 1631 requires write to a control register to start the conversion. No data is involved, just needs 2 bytes sent - the device address and the...

This piece of code is generated by the Datalogger Wizard. Why does the highlited line not cause an error? if address > 4095 then memory_full i2cslave %10100000, i2cslow, i2cword writei2c address,(data0) pause 10 readi2c address,(temp_byte) if temp_byte <> data0 then ee_error temp_word =...

I have a 20M2 picaxe based memory tester that functions correctly in simulation. My concern is I must ensure that my '-chip select' line does not go to a logic "0" during power up of the hardware, or it will invalidate the test. I believe that all pins are configured as inputs at startup...
