  1. Hi 430h Energia Experts I'm using Energia along with cc3200, i feel using energia is simple and straight since I'm not a "c" expert. I understand that cc3200 has two UART ports (uart0 and uart1) uart0 is in GPIO P01 and P02 - when Jumper J6 and J7 are connected uart1 is in GPIO P57 and P55 - when Jumper J6 and J7 are NOT connected While working on a project with cc3200 I used P01 & P02 as UART1 (Jumper J6 and J7 are connected) to communicate to device1 and now I would like to add another UART based device for which I would like to use UART0 without disturbing UART1 - how to do it? can some one please explain how PIN MUX in energia can be achieved and how to make use of both UART0 and UART1 at the same time in cc3200? Thanks! RRG
  2. Hi Experts I'm using cc3200 MOD and currently using GPIO pin "P01 and P02" as UART modul I know cc3200 has two UART modules - one can be from P01andP02 and other is from P55 and P57. I have a requirement whare I need to retain UART0 and URAT1 for two different use case - one fore display and other to transmit data. I'm using Energia for coding and new to this pinmux etc., Question: from where I need to do the configuration? Should I need to update my INO file? if so with what? can you please help! appreciate your time. Regards,
  3. Hi Andy I'm referring to this post which I recently updated seeking for some guidance. I'm using cc3200 LP and now facing conflict between UART1 (Serial1) Vs I2C where default ports mentioned are 9 and 10 (P01 and P02) for both!! can we have I2C configured or multiplexed to some other GPIO ports? if so how? Thanks!
  4. BTW, I just referred this topic. Hope multiplexing is possible shall try and let you know.. All what I need to do is either #1) Move the Serilal1 (UART1) to other GPIO pin (say 56, 57) and retain default I2C pin as 9 & 10. #2) Move the I2C from 9 or 10 to some other GPIO and retain UART2 as is... any other suggestions!!
  5. I agree! Since I dont have logic analyszer.. I'm forced to do trial and error After many trials finally I got work around .. so now my circuit looks like CC3200 -> UART1 (Serial1) -> TTL/232 -> 232/485 -> external device which has RS485 Where Serial1 = P01 and P02 But I was expecting to have below connection which did not work CC3200 -> UART (Serial) -> TTL/232 -> 232/485 -> external device which has RS485 Where Serial = P03 and P04 Any ways .. thanks for reading and suggestion! Love this forum !
  6. This is what I did and working for I2C... and the same pin is what I'm using for Serial1 (UART communication) also so there is a conflict. Is it possible to do multiplexing between I2C and UART1 (serial1) which has same pin 9 and 10 ??
  7. Hi FmilBurn, Thanks for your reply... From the Note: "...Note: the lighter colors indicate no connects..." Does it mean in cc3200 LP we just have only one I2C ?? that is conflicting with UART1 (Serial1) ?? is it possible for me to do multiplexing?? please help, both Serial communication and I2C interface are important for my project Regards,
  8. Case 3 cc3200 with simple Serial1.print "A & 8" flashed ==> through converter TTL/232 => 232/485 converter => USB/485 converter ==> Laptop/Tera Term (COM port console) :: Result Failure Update>> The above did not work (may be) the USB/485 converter is bad or I was missing something ... But when I modified above conversions as below through converter TTL/232 => 232/USB converter => Laptop/Tera Term (COM port console) :: Result PASS I used Serila1 which is P01 and P02 in CC3200 LP Till today I'm still NOT clear why other serial (say TX(0) or RX(0) ) which is mentioned in block diagram did not help me
  9. Hi I'm using external RTC which has DS1307 where it communicates to my cc3200 using (SDA and SCL) I2C. Please note as oer block diagram there are two I2C interface available in cc3200 LP I'm using RTC lib specified for ds1307 from here Option #1: when I connect my RTC module to Pin P01 and P02 (SCL and SDA) as detailed in CC3200 block diagram I see valid clock/time in my COM port Option #2: Now, When I try the with other I2C port in P4 40 and 39 (top two pins) I'm not seeing any clock/timer value Please help me to understand what might be the reason? why one I2C interface works while other does not? I'm not changing anything in my code/circuit I'm using Serial1 (which is also P01 and P02 similar to one of the I2c port interface) to communicate with other components.. thus we have only one choice to make use of P4 -40 and 39 ports to perform I2C... please help. Thanks!
  10. Hi Can some one help me to understand what is the pin number for Serial. port when used in BP (non-flash mode) The doc says it's P03 (Tx ) and P04 (Rx) but looks like the value are showing always ZERO BTW, I tried with Serial1. and it works perfectly for the same sketch. My Sketch
  11. Hey folks.. can you please check this topic and suggested what i'm missing
  12. This is in continuation with this post where I was working with two cc3200 one for transmit second for receive so my Energia code as described in other posted was /* Serial Transmit:*/ and for receive Please note: TX pin (P01) in transmit CC3200 is connected to RX pin (P02) of receiver CC3200 PS: P01 == P1-10 P02 == P1-9 The above is working fine and could see character "c" printed in console Now... when I change the Transmitter code as below where I have replaced "serial1" with "Serial" as shown below ... I'm NOT see any results - what is that I'm missing Please note - I've connected TX pin (P03) in transmit CC3200 is connected to RX pin (P02) of receiver CC3200 PS: P04 == P1- 3 P03 == P1-4 Thanks!
  13. Lovely! Catch is #1) Baud Rate .. for Serial > Serial1 #2) Baud Rate for Serial1 in Transmitter == Serial1 in Receiver Also, while sampling on computer com port make sure we set Receiver Serial baud rate (NOT Serial1) I've tried this with TWO CC3200 and Screen shot attached! please watch out for #1) baud rate in COM port console #2) and TX pin (P01) in transmit CC3200 is connected to RX pin (P02) of receiver CC3200 PS: P01 == P1-10 P02 == P1-9
