Good morning, I am using a 6-axis BMI270 sensor marked "5N 0KC" which replies to me a different wrong chip ID (0x26 instead of 0x24) and does not allow me to enable the accelerometer and gyroscope. I am using another one marked "5W 037" which responds with a correct chip ID (0x24), it allows me to enable the sensors but I cannot modify the ODR of the accelerometer below 200Hz. I would like to know what "internal use" means in section 8.4 "MARKING", in the table "MASS PRODUCTIN - internal code" on page 146 of document BST-BMI270-DS000-06 (document version 1.4) I would also like to know what are the possible correct markings that only identify the BMI270 (not L or W or N or P or E) and what can I do if the supplier has fitted me with one marked "P". Thank you.

Good Mornig, with the PIC32 Microchip microcontroller the compiler acept the original declaration of vector "uint8_t temp_buf[temp_len];"

I have discovered that can't use malloc () and free () on 8-bit microcontrollers family as describe in the page of compiler manual attached. Now i think to migrate an 32-bit Microchip microcontroller to obtain more memory space. Thanks anyway

Hello Kilohercas, thank you for your post. I tried to identify the maximum number of registers that the array could contain: the registers of the BMX160 device are 126, for safety I added 16 bytes so I declared that vector as "static uint8_t temp_buf [142];" this allows it to compile but i have yet to try if it works. Has anyone ever tried to do it this way?

Hello, i'm new of this forum, i try to use the API of "bmx160.h" files with an 8-bit microcntroller in C- language but there is a declaretion of an array inside a function that needed dinamic allocation of memory. In the file attached the array is named "uint8_t temp_buf[temp_len];" and the dimension of array "temp_len" is a parameter passed to the function. The compiler give me this error: "BMX160_drivers/bmi160.c:1369:21: error: variable length arrays are not supported" . Does anyone know what needs to be done to make the compiler allocate memory? Thank you!
