TMS570LC4357: Multiple communication protocol

Sir  do you have  any  thread on  I2C  , Iam  working  on example  code  of   I2C  using  Microcontroller  TMS570LC4357 , open drain  connection  external  connection  any details  please share me  sir  it  will really  useful for me , kindly reply me  soon sir 

Thank  you,

I am   trying  to implement  one   logic  for   multiple communication protocol  like  SCI, SPI, I2C , CAN even  RTI  also , all communication should  be  happen  in  single  code,  i will it  possible .

Yes, it is possible.

You just need to combine all the codes in while(1) loop one after another.

If any peripherals working with interrupts, you just need to add the corresponding code as well.

I2c examples can be found in HALCoGen itself at Help Topics section

If necessary you can find some more tested examples at below FAQ as well:

Dear  After  code  and  halcogen   set  ,for  microcontroller(TMS570LC4357)   external full up resistor  should   be required , what will be  value of  resistor . I making  I2C1  as  master  and  I2C2  as  slave  ,that is why  i am asking   external  pull resistor connection  ,  can u give any suggestion related to that  , as  soon as possible 

thank you 

dear sir,

To  calculate   full  resistor  i am  using   formula   R =  (T_rise)/(2* Total capacitance)   After  referring  data sheets  of  TMS570LS4357   I got  T_rise =  4.2 micro sec,  Total  Capacitance  = 400pf,  after calculation  its  getting  5.875 ohm ,  it   is  correct  sir , reply soon sir    ,.

Hi Jeev,

Please try to use either 2.2K or 2.7K resistors as I2c Pullups.

The code looks fine.

dear   sir ,

i  have  one  doubt  if  i have  send  through dock light  application  data  in  UART   communication , received  buffer array i  assigned  size as  20  , in   dock light  i want  to send  more that  20 char or  integer  whatever.  it  should  be  send , whatever  i  type  along  with  receiver size  also increase  it  possible sir , if  its  possible  means how  can u explain sir , kindly reply  fast 

thank you

sir   no  reply  i am  with  struct  due  to  above mention  problem , kindly  response   fast

Hi Jeev,

It is hard to support all the peripheral issues in one thread. 

Plese raise a different thread, because in future it is difficult to analyze the threads. Please raise at least one thread for one issue.
