I have a custom board with Texas Instruments' CC1310, I want to send this board's coordinates via RF with bma400's help. RF part is ok, there are files on github as reference but I want to know if there is an example code for TI MCU's. I want to move quickly that's why I need help about that topic. If there is no sample doc as I want, how can I adapt files on github to my project ?
Solved! Go to Solution.
Your interface modification looks okay, but in your code, reset funciton is before init function.
If so, your data log should be reset first as below.
|MOSI: 0x7E; MISO: 0x00|
|MOSI: 0xB6; MISO: 0x00|
And, for SPI reading in BMA400, we need one dummy byte. ( bma400.c line 593)
For example, in case of chip ID, data log shall be as below.
|MOSI: 0x80; MISO: 0x00|
|MOSI: 0x00; MISO: 0x00|
|MOSI: 0x00; MISO: 0x24|
However, in your log, MOSI just sent two bytes as 0x80, 0x00.
I think you can check based on this one.
Please let me know if you have any quesitons.
Thank you, I have checked SPI mod, Picture I have sent previous message was CPOL = '0' and CPHA = '0'. I read the document and as you shared it supports 0-0 and 1-1 modes. I also tried 1-1 mode, result is same on my side. I see no data on miso line. Maybe poor soldering cause this, I am not sure.
