- Mon Jan 09, 2017 1:42 am #60694 Hi,

We are trying to interface the memory IC(24C32) with the esp8266 using the esp8266basic. We have successfully interfaced it with the help of arduino but unsuccessful with esp8266basic

here is the code which I am working with

Code: Select allcls

let eeprom_address = 0
button "i2c Find" [I2C_find]
button "i2c Read" [I2C_read]
button "i2c Write" [I2C_Write]
wait

[I2C_find]
for address = 1 to 127
   i2c.begin(address)
   stat = i2c.end()

   if stat < 1 then
     ' print stat
      print "Found I2C device at address: 0x" & hex(address)
      print " - > " & address
      print " <br>"
      got_address = address
endif
next
wait

[I2C_Write]
 print "writing to address " & got_address
 i2c.begin(got_address)
 i2c.write(eeprom_address >> 8)
 i2c.write(eeprom_address)
 i2c.write("A")
 i2c.end()
 print "write complete"
wait

[I2C_read]
  print "reading from address " & got_address
  i2c.begin(got_address)
  i2c.write(eeprom_address >> 8)
  i2c.write(eeprom_address)
  i2c.end()

  i2c.requestfrom(got_address,1)
  if i2c.available() then
     i2c_read = i2c.read()
     i2c.end()   
     print  "the data is " & i2c_read
  end if
  print "read complete"
wait


kindly let us know where we are going wrong.

Thanking you in anticipation.
