Hello,
I'm trying to connect my LIS35DE accelerometer to piccolo c2000 launchpad using matlab/simulink embedded coder for c2000 processors. Slave address of LIS35DE is 29 (dec), and im trying to read register number 32, which value should equal 7, i check and this device works. I already made some programs using simulink embedded coder for this MCU and it work great, so i dont think its any connection problem.
Module clock prescaler and Master clock Low and High -time divider are set to give 100kHz i2c data transmition rate.
I tried debuging using SCI connection, and i got:
1. data transmiter status is: 0x10 0x34 but i'm recieving "Inital output" (default: 0).
2. if i change slave address to none existing like 13 i get: 0x86 0x14 (transmiter status) and 0 from receiver.
i read the eeprom example, but is complicate and i dont have a eeprom now...
what exactly are the i2c pins of the C282027?
i dont know if have default pins or i can enable that i want and where exactly in the library "embedded coder" i can configurate that pins... when i put the osciloscope in all the pins trying to find the clock signal (SCL pin) only appear a constant of 3.3 volts.... or if i need pull-up resistances... i make a new threat, if someone can help me with that.
